Unless you’re an HVAC professional—like the team at Clear Air Conditioning & Heating you probably don’t spend much time thinking about your air conditioner or how it works.

Yet, according to the U.S. Energy Information Administration, about 90% of households in the U.S. use air conditioning. So while you may just care that it keeps your Peoria, home or business cool, understanding a little more about your system can help you recognize when something’s not working quite right.

Let’s break it down.

A Brief History of AC Technology

Air conditioning has come a long way since its invention in 1902 by Willis Carrier. Originally used to control humidity in a printing facility, the technology quickly made its way into theaters, department stores, and eventually homes.

Today, central air systems are not only more efficient and quieter but often come with smart controls and zoning capabilities. Understanding how your system works empowers you to make smarter decisions about maintenance, upgrades, and repairs.

What Does an Air Conditioner Actually Do?

Your central air conditioner does more than just cool your space. It also:

• Removes humidity from the air by drawing out excess moisture (hence the need for pans and drain lines).
• Improves indoor air quality by pulling allergens and debris out of the air through the filter.
• And of course, it lowers the indoor temperature by removing heat from your home and releasing it outside.

To do all this, most central AC systems use a “split system,” with a hot side (outside unit) and a cool side (inside unit). These two sides work together to extract heat from the air in your home and transfer it outdoors.

Here’s a simplified explanation of how that process works:

1. Warm indoor air is drawn into the system.
2. The refrigerant inside the system absorbs the heat from the air.
3. The heated refrigerant is pumped through a closed-loop system to the outdoor unit.
4. A fan blows over the outdoor coil, releasing the heat into the outdoor air.
5. The refrigerant cools back down and cycles back inside to absorb more heat.

This heat-transfer process repeats continuously to keep your home comfortable. And while the overall system involves many small moving parts, the core components are what really keep things running.

How Refrigerant Makes Cooling Possible

Refrigerant is the key to your air conditioner’s cooling power. This chemical compound absorbs and carries heat as it circulates through your system. As it evaporates into a gas inside the indoor unit, it draws heat from the surrounding air. When compressed and pushed into the outdoor unit, it releases that heat and condenses back into a liquid.

This cycle of phase changes—from gas to liquid and back again—is what makes modern cooling possible. Maintaining the right refrigerant level is essential. Too much or too little can lead to poor performance, frozen coils, or even compressor failure.

Key Components of a Central Air Conditioner

Of course, your Peoria, home’s AC system also includes other essential parts—fans, filters, sensors, and more—but these four components are the backbone of your cooling system.

Evaporator (Indoor Unit)

The evaporator is located inside your home on the cool side of the system. It receives the cold, liquid refrigerant. As warm air blows over its chilled coils, the refrigerant absorbs the heat and evaporates into a gas. This process cools the air before it’s circulated back through your home.

Condenser (Outdoor Unit)

The condenser sits outside on the hot side. It works the opposite of the evaporator, converting the refrigerant gas—now carrying heat from your home—back into a liquid. The condenser’s coil releases this heat into the outside air, thanks to a fan that blows across it.

Expansion Valve

The expansion valve is the control center between the condenser and evaporator. It regulates how much refrigerant enters the evaporator. As it removes pressure from the refrigerant, it allows it to expand and turn into a gas, enabling the cooling cycle to restart.

Compressor

The compressor is also located outside and acts like the heart of the system. It pressurizes the refrigerant gas, which raises its temperature and prepares it to release heat once it reaches the condenser coil. The compressor keeps refrigerant circulating through the system in a closed loop.

Boosting Indoor Air Quality With Your AC

Your central air conditioner can do more than cool your home—it can also support cleaner, healthier indoor air. Consider adding IAQ indoor air quality products like UV light air purifiers, electrostatic or HEPA filters, or a whole-home dehumidifier.

These upgrades work alongside your HVAC system to reduce allergens, neutralize bacteria and mold spores, and manage excess humidity.

The result? Cleaner air and a more comfortable home environment.

Frequently Asked Questions About Air Conditioners

How often should I service my air conditioner?

We recommend a professional tune-up at least once a year—ideally in the spring before peak cooling season.

Can I clean my AC coils myself?

You can gently rinse your outdoor coil with a garden hose to remove debris, but internal components like the evaporator coil should be cleaned by a licensed technician to avoid damage or voiding your warranty.

Why is my air conditioner running but not cooling?

This could be due to low refrigerant, dirty coils, a malfunctioning compressor, or a blocked air filter. Call a professional for a full system inspection.

An air conditioner is your lifeline during a prolonged heat wave.

This life-saving comfort system is a necessity when temperatures soar and linger in Peoria as they have under the heat dome that has scorched across Arizona. 

Risking an AC breakdown during extreme heat also risks your health. According to the National Weather Service, heat-related fatalities in 2023 surpassed deaths related to tornadoes, lightning, floods, hurricanes, and other weather events.

With much of the U.S. broiling in high temperatures this summer, you will likely only find relief from the heat with a reliable AC. And to have one of those, you’ll want to follow these three tips to avoid your AC from having a breakdown:

• Schedule AC Maintenance ASAP
• Upgrade to High-Efficiency AC
• Staying on Top of AC Air Filter Changes

Professional Help for Your Air Conditioning

Fortunately, at Clear Air Conditioning & Heating Inc., we are committed to your well-being and comfort year-round and during all weather conditions. We recognize our expertise is in high demand in the summer when the cooling season is in full swing and extreme temperatures dominate Southwest heat forecasts.  

We are available to restore air conditioning to your Peoria home. We respond to requests for AC repair quickly but prefer to help you avoid the need for repairs. 

Breakdowns are not inevitable. Here are three ways to insulate your home from an air conditioning malfunction during a heat wave:

• Schedule AC Maintenance ASAP
  Why risk the need for emergency AC repairs this summer when you can schedule a system checkup now? Tune-ups are the best way to get your air conditioner in shape for high temperatures.
  
  During maintenance, our licensed technicians at Clear Air Conditioning & Heating Inc. will clean and lubricate components, check the refrigerant level, inspect electrical connections, and assess the unit’s performance. We can catch and fix problems before they spiral out of control and trigger other issues.
  
  A tune-up will boost your system’s energy efficiency and prepare it to handle intense heat. You will welcome the restored efficiency when you check your monthly electricity bill. You will also feel relieved knowing you scheduled professional maintenance before AC repairs swamp HVAC technicians.
  
  As summer rolls on and the heat intensifies, scheduling a repair technician at your preferred time can be challenging.

• Upgrade to High-Efficiency AC If your air conditioner is over 10 years old, needs frequent repairs, or has significant problems, replacing it with a high-efficiency unit will save money on repairs and energy bills, improving cooling and humidity-reducing performance.
  
  A high-efficiency air conditioner uses less energy than your outdated system and reduces your impact on the environment. Its variable-speed compressor with inverter technology adjusts its speed to deliver the cooling needed.
  
  It turns on, speeds up, and attains cooling capacity, reaching the desired temperature on your thermostat. It slows and runs at a lower speed to maintain the temperature.
  
  A conventional compressor turns on, runs at capacity until it reaches the desired temperature, and then turns off. When the indoor temperature falls below the set point, the compressor turns on again. Constant stopping and starting expends energy and shortens component lifespan through wear and tear.
  
  High-efficiency air conditioners are also quiet and better at reducing humidity.

• Staying on Top of AC Air Filter Changes Replacing your air filter is an easy maintenance task that yields significant results. Your air conditioner runs more frequently during a heat wave. If it operates with a dirty, debris-clogged air filter, it loses efficiency and might even overheat. A dirty filter restricts airflow, which could lead to a breakdown.
  
  Check your filter for dirt at least monthly and more frequently during a prolonged heat wave. Refer to your AC owner’s manual for the filters your system should use.

A good night’s sleep is essential for your overall health and well-being. Sleep affects everything from your mood and energy levels to your immune system and physical health. That’s why maintaining a comfortable sleeping environment is so important, especially during warm nights when high temperatures can disrupt your rest.

At Clear Air Conditioning & Heating, Inc, we understand how critical sleep is to your everyday life. That’s why we’re dedicated to providing our customers in Glendale with reliable air conditioning systems that ensure maximum comfort, day and night.

Running your AC while you sleep isn’t just about comfort—it also offers several health benefits. Let’s dive into why keeping your home cool at night can help you feel your best.

Getting It Right: The Ideal Sleeping Temperature

Research published by the National Center for Biotechnology Information (NCBI), part of the US National Library of Medicine (NLM) recommends setting your thermostat between 60 and 68 degrees Fahrenheit at night for optimal sleep quality. This temperature range helps your body maintain its natural cooling process, which is vital for deep, restorative sleep.

When your bedroom is set to this ideal temperature, your body doesn’t need to work as hard to regulate its own temperature. This creates a consistent, comfortable environment that helps prevent frequent waking. No more tossing and turning or fumbling with blankets! With your AC doing the work, you can settle into a restful, uninterrupted night’s sleep.

Keeping It Right: Maintain Your AC for Consistent Comfort

Your air conditioner plays a crucial role in maintaining the perfect sleeping temperature, but it can only do so if it’s in top condition. Regular maintenance is essential to prevent unexpected breakdowns or inefficiencies.

Scheduling professional AC maintenance ensures your system is clean, free from dust and debris, and operating at peak performance. During a tune-up, our technicians thoroughly inspect your unit for leaks, cracks, or worn components that could compromise your comfort. By staying ahead of potential issues, you’ll be able to rely on your AC to keep you cool and comfortable through the hottest nights.

The Right Benefits: Health Advantages of Sleeping Cool

When your air conditioner is running efficiently, you’ll enjoy more than just a good night’s sleep. Lowering your thermostat at night provides several health benefits:

1. Improves Your Mood and Mental Health

The connection between sleep and mental health is undeniable. When you sleep in a cool, comfortable environment, you’re less likely to wake up throughout the night. This uninterrupted sleep helps you feel refreshed, alert, and positive during the day.

Lack of sleep can lead to irritability, fatigue, and difficulty concentrating. By optimizing your sleeping conditions, you’re setting yourself up for better emotional resilience and cognitive function, which allows you to tackle your daily challenges with a clear mind.

2. Slows Signs of Aging

Cooler sleeping environments encourage your body to produce more melatonin—a powerful hormone known for its anti-aging properties. Melatonin not only helps regulate your sleep-wake cycle but also acts as a natural antioxidant, protecting your skin from premature aging and reducing the appearance of wrinkles.

By creating the right conditions for quality sleep, you’re giving your body the chance to repair and rejuvenate itself. This simple step can lead to healthier, more radiant skin over time.

3. Supports Weight Loss and Metabolism

Quality sleep is a key component of maintaining a healthy weight, and sleeping in a cooler room can play a significant role in this process. When you sleep, your body burns calories to maintain its core temperature. Cooler environments can enhance this calorie-burning process, contributing to weight loss.

Additionally, poor sleep disrupts hormones like ghrelin and leptin, which regulate hunger and appetite. A comfortable, cool sleeping environment promotes better hormonal balance, helping you stick to a healthy diet and avoid overeating.

Extra Tips for Better Sleep With Your AC

To get the most out of your air conditioner at night, follow these tips:

• Use a programmable thermostat: Set your AC to adjust to your ideal sleeping temperature during bedtime automatically.
• Optimize airflow: Ensure your vents are open and unobstructed to maintain consistent cooling.
• Invest in blackout curtains: These help block heat from entering your home during the day, so your AC doesn’t have to work as hard at night.
• Upgrade your system if needed: An energy-efficient AC unit not only cools better but also saves on energy costs.

July 17 is the coolest date on the calendar.

It marks National Air Conditioning Day, commemorating the work of Willis Carrier, the father of the modern-day indoor air conditioning system. It is the perfect time to put your feet up, chill out, and luxuriate in the cool comfort of your Arizona home.

Is your heating, ventilation, and air conditioning (HVAC) equipment ready for National Air Conditioning Day? Can it handle the long, hot summer of Arizona or does it barely scrape by on an occasional scorcher?

Clear Air Conditioning & Heating Inc. can keep your air conditioner running efficiently, no matter how high the outdoor temperature rises.

You do not have to wait until National Air Conditioning Day to give your system a little TLC. By scheduling an annual checkup in the spring, you will avoid the HVAC industry’s busy summer season. Your air conditioning system will be ready to work when you need it the most.

Is an Annual AC Tune-up Necessary?

If you expect your equipment to run efficiently for as long as possible without unexpected breakdowns, an annual inspection, cleaning, and tune-up are essential.

According to the U.S. Department of Energy, central air conditioning systems have a service life of approximately 15 to 20 years. Almost any piece of equipment with moving parts, whether it is the HVAC system in your home or the motor in the vehicle you drive, will not run efficiently for more than a decade without regular maintenance.

Skipping the annual tune-up on your air conditioning system in Peoria may save you money now, but you will spend more in the long run if your system breaks down. The longer you delay maintenance, the more likely something will go wrong as your HVAC system ages.

What Could Happen if I Skip AC Maintenance?

You wouldn’t skip an oil change in your car—it’s too much of a risk that it would break down. Caring for your AC should be of a similar mindset. Here’s what could happen if you skip annual maintenance of your air conditioner:

• Refrigerant loss: If the system is losing refrigerant, you may notice ice over the coils, and the air blowing from the registers will not feel cool. Too little or too much refrigerant can affect the system’s compressor.
• Worn or faulty parts: A broken fan belt, fan bearings clogged by dirt build-up, or a burned-out motor, for example, will stop the fan in your system from working. You will not feel any air blowing from the duct registers.
• Clogged drain line: A build-up of sludge in the drain line can cause water to overflow the condensate drain pan and possibly damage your home.

The best way to avoid repairing or replacing equipment is to be proactive about maintenance. Make sure to schedule an annual inspection, cleaning, and tune-up.

What Should an AC Maintenance Checkup Include?

An ENERGY STAR^® maintenance checklist recommends checking thermostat settings, inspecting and tightening electrical connections, lubricating moving parts, inspecting the drain line, checking system controls, cleaning and adjusting blower components, cleaning the condenser and evaporator coils, and checking the refrigerant.

Most tune-ups also include a filter inspection and replacement. Dirty filters can restrict airflow and cause your AC to work inefficiently. Inspecting and changing the air filter monthly throughout the cooling season is an easy do-it-yourself project.

What Other AC Maintenance Tasks Can You Do Yourself?

In addition to changing your air conditioner’s filter, keep the outdoor unit clear of shrubs, brush, and other obstructions that could impede airflow.

Keep furniture from blocking indoor air registers, and occasionally vacuum registers to remove dust.

Remember to schedule your system’s annual inspection—and get ready to celebrate on July 17!

Stay Cool All Summer

Why is your air conditioner blowing out warm air when it should be keeping you cool inside your STATE home? Here are a few reasons why your AC might be blowing hot air:

• Your Thermostat Is Set Incorrectly
  Did you accidentally set your thermostat to Heat instead of Cool? If so, resolving the issue is simple—just set your thermostat to Cool!
  
  Tip: turn your thermostat fan setting from AUTO to ON during those super muggy days in the summer. Doing so will lower the humidity inside your Glendale home and improve the indoor air quality (IAQ).
  
  
• Your Refrigerant Is Leaking
  Low refrigerant levels could be the reason your air conditioner is blowing out warm air. If you have a refrigerant leak, your system will run low on refrigerant, causing your air conditioner to struggle to keep your home at the temperature set on the thermostat.
  
  Turn to Clean Air Conditioning & Heating to check your AC refrigerant levels. If our professionals discover a refrigerant leak, we will address the issue, get your refrigerant levels to the appropriate range, and restore the comfort of your home.
  
  
• Your AC Filter Is Clogged
  A clogged filter can result in restricted airflow and prevent your air conditioner from keeping your home cool. Protect your HVAC system—and your comfort—by replacing a disposable filter or cleaning a washable filter every 30 to 90 days.
  
  Consider upgrading your filter. According to the Environmental Protection Agency (EPA), a high-efficiency particulate air (HEPA) filter can trap 99.97 percent of dust, pollen, mold, bacteria, and particles, some as small as the size of 0.3 microns! Be sure the filter is compatible with your system—otherwise, the filter will restrict your system’s airflow.
  
  
• Your Evaporator or Condenser Coils Are Dirty
  Dirty evaporator and condenser coils impede the airflow, preventing your home from feeling cool. It can also cause ice to form on your outdoor condenser unit. If condensation forms over the dirt and freezes, your entire air conditioning system could be at risk of breaking down completely.
  
  Our Clean Air Conditioning & Heating professionals can diagnose any issues you are experiencing with your air conditioner and correct them so you can return to enjoying the comfort of your home. To prevent damage in the future, be sure all air conditioning parts and components are routinely inspected, cleaned, and maintained.

Spring is finally arriving in Arizona! The days are getting longer, the flowers are blooming, and you’re probably already thinking about dusting off the patio furniture or tackling that messy garage.

But there’s one essential part of your Phoenix home that also needs some TLC this season—your air conditioning system! Just like you wouldn’t ignore a dust bunny atop your fridge during spring cleaning, your heating and cooling system deserves some attention too.

A few AC maintenance tasks can go a long way in improving efficiency, airflow, and indoor air quality. From replacing air filters to scheduling professional maintenance with Clear Air Conditioning & Heating, spring cleaning for your cooling system can prevent breakdowns and keep your home comfortable.

Not sure where to start? Read on for essential AC cleaning tips to keep your system running smoothly this spring!

The Importance of Spring AC Maintenance

After working hard all winter to keep your home warm, your air conditioning system deserves a refresh before it starts cooling things down for the summer. Dust, debris, and even pet hair can accumulate in your system, reducing efficiency and potentially leading to unexpected breakdowns just when you need your air conditioning the most.

A well-maintained AC system doesn’t just work better—it also helps you breathe easier. If you’ve ever wondered, “Why is my room so stuffy?” or “What is that smell coming from my air ducts?” the culprit is often a neglected HVAC system.

Dust, mold, and other pollutants can build up in your ductwork and filters, circulating throughout your home and affecting your indoor air quality.

3 Simple Steps to Spring Clean Your HVAC

Now that we’ve established why HVAC maintenance is important, let’s get into what you can do to keep your system running smoothly.

1. Change Your Air Filters

Your HVAC’s air filters trap dust, pollen, and other airborne particles, keeping them from recirculating in your home. However, most filters only last 30 to 90 days before they need to be changed.

Skipping a filter change can reduce airflow and force your system to work harder.

Replacing your air filters on a timely schedule can prevent that “stuffy” feeling in your home and improve overall air quality.

2. Clean Your Vents and Registers

While you have the vacuum out for regular spring cleaning, take a few minutes to vacuum your air vents and registers to remove dust buildup. This helps improve airflow and prevents allergens from getting kicked up into your duct system.

If you notice a persistent odor when your system is running and find yourself asking, “What is that smell coming from my air ducts?” it might be time for a professional duct cleaning. Mold, dust, or even pests can lurk in neglected ductwork, affecting both your air quality and your health.

3. Check and Clean the Outdoor Unit

Your AC’s outdoor unit has likely accumulated leaves, dirt, and debris over the fall and winter months. A clogged condenser coil can cause your system to overheat or run inefficiently, which could lead to the dreaded “Why is my AC blowing warm air?” moment on the first hot day of the season.

Give the unit a good rinse with a hose (after turning off the power) and clear any debris around it to ensure proper airflow.

Schedule a Professional Tune-Up

While regular maintenance helps, a professional AC tune-up is the best way to keep your system running efficiently. A technician will check refrigerant levels and clean critical internal components like the evaporator coil.

Over time, this coil can accumulate dust, pet hair, pollen, and other particles—especially if the air filter is clogged and ineffective. This buildup can lead to a burning smell when you first switch your HVAC system to cooling as the debris heats up.

An HVAC technician can also thoroughly inspect your unit to ensure there are no potential issues that could leave you sweating when summer hits. Plus, regular maintenance can extend the lifespan of your system and even lower your energy bills!

The Indoor Air Quality Factor: Breathing Easier at Home

Good indoor air quality (IAQ) is key to a healthier, more comfortable home. If you notice excessive dust, lingering odors, or allergy symptoms, your air may not be as clean as it should be.

Here are a few ways to improve IAQ:

• Upgrade your air filter: A high-quality filter, such as a HEPA or media filter, captures more airborne pollutants than a standard filter, reducing allergens and dust. Be sure the filter is compatible with your system.
• Use an air purifier: Whole-home air purifiers help remove bacteria, viruses, and other contaminants, improving overall air quality.
• Control humidity levels: A whole-home dehumidifier or humidifier keeps moisture levels balanced, preventing issues like mold growth and dry air discomfort.

Breathe Easy With Spring AC Cleaning

Spring cleaning isn’t just about tidying up—it’s about creating a healthier, more comfortable home. By giving your cooling system the attention it needs, you can enjoy better air quality, improved efficiency, and peace of mind knowing your system is ready for summer.

So, grab that vacuum, swap out those filters, and get your AC in top shape—your lungs (and your energy bill) will thank you!

Your air conditioner (AC) can do several things––keep your Arizona home’s indoor air cooler than outdoor temperatures, help to keep indoor airborne allergens at bay, and help keep your home’s humidity low. But one thing it can’t do is kill mold.

It can help prevent mold, but once it exists, your air conditioner can’t kill it. If you find mold exists somewhere in your heating, ventilation, and air conditioning (HVAC) system, particularly in your air conditioner or ductwork, call Clear Air Conditioning & Heating for assistance. We can guide you on ridding your home of the mold and help maintain your HVAC system to prevent the mold from recurring.

How Does Mold Occur?

Mold needs a damp, humid environment to breed. That means water is part of mold’s equation. Remove the water, and mold can’t live. According to the US Environmental Protection Agency (EPA), mold already exists in all homes, even in your Peoria home. But in most cases, it exists on such a small scale that it’s not noticeable or a health risk. It’s when that damp, humid environment is introduced that mold grows.

This mold-ideal environment can be introduced because of an unknown or ignored leak somewhere in your home or high humidity. Air with over 70 percent humidity is a definite breeding ground for mold. Once the mold begins to grow, the spores can travel through your home’s air causing allergen issues. A small leak in your HVAC system or ignored air conditioner drains and pans, evaporator coils, or air handlers could very well be an origin of mold.

How Can My Air Conditioner Prevent Mold?

As already mentioned, mold thrives in damp, humid environments. Your air conditioner is designed to help dehumidify your home, removing excess moisture and preventing mold’s growth. So keeping your air conditioner running in humid weather and situations is a proactive step to take.

Mold also likes stale air. Running your air conditioner provides proper ventilation and airflow in your home, thereby preventing mold’s growth again. If you decide to leave your home during high temperatures or high humidity for more than a few days, it’s advisable to leave your air conditioner running with the fan set to ON, though you may be tempted to save a little energy and turn it off. The tradeoff in mold prevention in your home is well worth the amount of energy you would have saved.

What Do I Do If I Spot Mold?

Even if you take the proper precautions against mold in your home, you may still come across it, maybe on your air conditioner itself. What should you do?

There are times you can clean mold yourself, when there’s only a small amount. But sometimes you need a professional, as mold spores can be a health risk. It’s not uncommon for HVAC air handlers, evaporator coils, and condensation pans to have mold. A professional, like ours at Clear Air Conditioning & Heating, can take care of that mold during a regular air conditioner maintenance visit and explain how to avoid its recurrence.

The post Does an AC Kill Mold? first appeared on Clear Air Conditioning & Heating and is written by Clear Air Conditioning & Heating.

As the temperatures begin to rise in Peoria, many homeowners are firing up their air conditioners (AC) for the first time in months. But what if, instead of a refreshing blast of cool air, you’re hit with an unpleasant smell?

If your AC is producing an unusual odor at startup, you’re not alone. This is one of the most common concerns our team at Clear Air Conditioning & Heating hears every spring as homeowners transition back to cooling mode.

To assuage your concerns, we’ve compiled a list of common smells and their causes.

What’s That Smell Coming From My AC on Startup?

Let’s break down what might be causing these smells and what you can do about them.

1. Musty or Mildew Smell
If your AC smells like a damp basement or old gym socks, you might be dealing with mold or mildew growth inside your system. This often happens when moisture builds up in your air ducts or evaporator coils, creating the perfect environment for microbial growth.

What to Do:

• Check and replace your air filter if it’s clogged with dust and moisture.
• Schedule an AC tune-up and coil cleaning to remove any built-up mold or bacteria.
• Consider a whole-home dehumidifier if high humidity is a recurring issue in your home.

2. Burning Smell
A burning odor when you first turn on your AC could be due to dust accumulation on the heating elements or electrical components. If your system has been sitting unused for months, dust settles on the coils, wires, and motor. The dust burns off when you start it up, causing a brief but noticeable smell.

What to Do:

• If the smell disappears within a few minutes, it’s likely just dust burning off.
• If the odor persists, turn off the AC and check for any visible damage to wires or components. Then, call a professional HVAC technician to inspect your system for electrical issues or overheating parts.

3. Rotten Egg or Sulfur Smell
A sulfur or rotten egg smell is a major red flag, as it could indicate a natural gas leak near your HVAC system. While air conditioners don’t use natural gas, a nearby furnace, gas line, or stove could be leaking, and your AC could be circulating the odor throughout your home.

What to Do if You Notice a Sulfur Smell in Your House:

• Turn off your AC and exit the house immediately.
• Call your gas company or emergency services to inspect for a leak.
• Do not turn on any electrical appliances or light switches until professionals give the all-clear.

4. Chemical or Sweet Smell
A chemical odor, similar to acetone or sweet antifreeze, could indicate a refrigerant leak. Refrigerant is essential for cooling your home, and a leak can not only affect your AC’s performance but also pose health risks if inhaled over time.

What to Do:

• Turn off your AC and avoid prolonged exposure to the odor.
• Call a licensed HVAC technician to inspect and repair any refrigerant leaks.
• Never attempt to handle refrigerant yourself, as it requires specialized training and tools.

5. Dirty Socks or Sewage Smell
If your AC produces a foul, sewage-like smell, you might have a clogged condensate drain or an issue with sewer gas backing up through your home’s plumbing system. Bacteria can grow in stagnant water within the drain line, creating an unpleasant odor.

What to Do:

• Check and clean your AC’s condensate drain line to remove any blockages.
• Pour a mixture of white vinegar and warm water down the drain to kill bacteria.
• If the smell persists, contact a professional to inspect both your HVAC and plumbing systems.

Preventing Future AC Odors

To avoid these unpleasant smells when starting up your AC each spring, consider the following maintenance steps:

• Replace your air filters regularly (every 1–3 months, depending on usage and pets in the home).
• Schedule annual HVAC maintenance to clean your coils and drain line and inspect for potential issues.
• Ensure proper ventilation to prevent moisture buildup and microbial growth inside your system.
• Use UV air purifiers or high-quality air filtration systems to reduce bacteria, mold, and airborne contaminants.

When to Call an HVAC Professional

Everyone loves to save money, and it’s a good idea to review different aspects of your budget now and again to see if there are more opportunities you have missed in the past. Considering how to reduce your energy bills is always a great idea in the springtime.

According to the US Department of Energy (DOE), air conditioners use about 6 percent of all electricity in the country at a cost of roughly $29 billion to homeowners.

If you can reduce that usage in Peoria, you will be able to make a difference in our environment and save yourself some money as well. Take some of the following ideas from our professionals at Clear Air Conditioning & Heating Inc. to heart and make some money-saving resolutions today.

Saving Tips for Running Your AC 

Before it heats up too much in Peoria, start implementing some of these tips and take advantage of the resulting energy (and, subsequently, money) saving tips.

Tune-Up for Efficiency

All air conditioners work more efficiently if they have clean filters, enough refrigerant, spotless coils, and plenty of room for air circulation.

Although you can take care of some of these maintenance items on your own—clearing away fallen yard debris from around your outside condenser unit and regularly changing filters—you should engage one of our highly trained professionals to help inspect and clean your air conditioning components.

Our experts can also check your ductwork and be sure you are not losing your cooled air before it reaches its destination.

By investing in regular maintenance, your unit is less likely to break down in the dog days of summer, which is an extra bonus.

Work With Mother Nature

Find ways to use outdoor conditions to your advantage when it comes to saving energy. For example, during the spring and fall, when nighttime temperatures cool down, open all your windows to let the cool breeze in.

Then, first thing in the morning, close your windows and pull your shades to trap the cooler air inside. You can also consider planting trees to shade your home in the future.

Circulate Indoor Air

Consider investing in floor or ceiling fans to help move your indoor air. Fans use a lot less energy than air conditioning systems and do a good job cooling down your home in moderate temperatures. You can also run the fan on your heating, ventilation, and air conditioning (HVAC) system or install a whole-house fan that pulls fresh air from the attic.

Relocate Heat Outside

The sun is not always the biggest culprit in generating indoor heat. How often do you find that your appliances are competing directly with your air conditioner?

Instead of turning on your oven or stove, consider grilling outside to keep that heat out of your home. Or get a little creative and find some great cold meals to prepare instead.

The clothes dryer is another heat producer in most Arizona homes. Instead of running your dryer, put that springtime sun and a laundry line to work.

Block and Reflect

Another idea to reduce the heat and associated energy bills is to invest in energy-efficient windows, seals, and insulation to keep the cold in and the heat out. You can also install light-colored window coverings to block sun in the warmest part of the day.

Energy-efficient, reflective roof tiles or a coat of lighter exterior paint can do wonders in reflecting the heat of the sun away from your home’s outside.

Rely on Technology

At the very minimum, install a programmable thermostat that will automatically adjust your temperature requirements while you are away or asleep. Smart technology is advancing each day, and in some homes, rooms can now detect when you are present in them and adjust the temperatures accordingly. You can also control and monitor air conditioning usage from afar using a smart phone.

Don’t Forget the Little Things

Every light that’s left on when not in use generates heat as well as all those electronic devices. Consider switching to LED lightbulbs and turning off electronic gadgets when they are not being used to save money and reduce heat.

Today’s air conditioner (AC) is based on a prototype invented in 1902 by Willis Carrier, an engineer from Buffalo, New York. Unlike earlier forms of cooling, Carrier’s model controlled the temperature by removing heat and humidity from the air.

Since the early 20th century, engineers have significantly improved on Carrier’s initial design. Even in the past decade, cooling technology has become much more efficient. For instance, if you replace a 10-year-old air conditioning unit with a new efficiency model, your energy use could go down as much as 50 percent, according to the U.S. Department of Energy (DOE).

The Early Days of Air Conditioning

Did you know “evaporative cooling” is an old form of air conditioning that historians trace back to ancient Egypt and Persia? The process involves leaving out water, snow, or ice and letting it evaporate to cool an indoor area.

How Your AC Works

Air conditioners decrease indoor temperature through the refrigeration process. They circulate refrigerant, a substance that phases between liquid and gas. As this cycle occurs, the refrigerant grabs heat and humidity from the air, converting it to liquid water.

As a result, your home gets cooler and less humid––which leads to more comfort and better indoor air quality (IAQ).

Your AC has four basic components:

• The Evaporator
  This element sits inside. It is a collection of coils that absorbs heat and humidity from inside your home.

• The Condenser
  This unit that sits outside your home. It is responsible for releasing the heat that your evaporator collects into the outdoors.

• The Expansion Valve
  This component facilitates the flow of refrigerants. It can increase or decrease in size, allowing it to expand or convert from gas to liquid.

• Compressor
  This is a pump that applies pressure to the refrigerant to keep the flow going.

Common AC Mistakes

Here are four common mistakes to avoid when running your AC unit:

Mistake Number One: Leaving Doors or Windows Open

When your AC is running, you should keep your Arizonia home as airtight as possible. When doors are windows get left open, the cold air escapes, causing your AC to run longer. This leads to high utility bills and a shorter lifespan for your cooling equipment.

Mistake Number Two: Forgetting to Change Your Air Filter

HVAC filters need to be changed at least every 90 days. A clogged filter means your air ducts won’t be able to distribute cool air properly. It can also cause mechanical problems and reduce efficiency.

Mistake Number Three: Skipping Maintenance Inspections

Did you know most HVAC manufacturers require you to keep up with maintenance in order to keep your warranty? There’s a reason for that. Seasonal maintenance visits are important for the following reasons:

• Your HVAC system can achieve peak efficiency
• Your equipment will last longer
• Your HVAC specialist can discover and fix small problems before they turn into expensive repairs
