The Most Overlooked Indoor Air Quality Issues in Houston, TX

Have you ever walked into your home and felt like the air just doesn’t feel right? Maybe it feels heavy, dusty, or even slightly musty. In Houston, where humidity and heat can be relentless, indoor air quality (IAQ) is a concern that many homeowners overlook. Most people think of air quality only in terms of allergies or visible dust, but the truth is that the air inside your home can contain a wide range of invisible pollutants that affect your health and comfort every day. Understanding the most overlooked IAQ issues can help you take control of your indoor environment and protect the health of your family.

Why Indoor Air Quality Matters in Houston

Houston’s climate plays a big role in shaping indoor air quality concerns. High humidity, combined with a mix of urban pollution and allergens like pollen, creates an environment where mold, dust mites, and bacteria can thrive. According to the Environmental Protection Agency (EPA), indoor air can be two to five times more polluted than outdoor air, and poor air quality is linked to respiratory issues, allergies, and even long-term health effects.

The good news is that many of these problems are preventable or correctable with proper HVAC maintenance, air filtration, and professional indoor air quality services. But first, let’s explore the issues that often fly under the radar for Houston homeowners.

Hidden Moisture and Mold Growth

Why Moisture is a Problem

One of the most common but overlooked IAQ issues in Houston is hidden moisture. High humidity levels, often exceeding 70% during the summer, create ideal conditions for mold growth inside walls, under floors, and in attics. Mold spores are microscopic and can spread through your home via your HVAC system without you even noticing.

Health Risks of Mold

Mold exposure can trigger respiratory problems, headaches, sinus infections, and allergy flare-ups. In some cases, prolonged exposure can lead to more serious conditions like asthma exacerbation. According to the Centers for Disease Control and Prevention (CDC), children, elderly adults, and individuals with compromised immune systems are particularly vulnerable to mold-related health issues.

Prevention and Solutions

Proper ventilation, humidity control, and regular HVAC inspections are key to preventing hidden moisture. Installing a whole-home dehumidifier or maintaining your air conditioning system to manage humidity can significantly reduce mold growth and improve overall indoor air quality.

Dirty Ductwork and Air Vents

The Problem with Air Ducts

Many homeowners never think about the condition of their ductwork, but dirty ducts can significantly impact indoor air quality. Dust, pet dander, pollen, and even microbial contaminants can accumulate over time in ducts, only to be circulated throughout your home whenever your HVAC system runs.

The Impact on Health and Efficiency

Clogged or contaminated ducts can exacerbate allergies and respiratory issues. Additionally, dirty ducts can make your HVAC system work harder, reducing efficiency and increasing energy costs. Studies by the National Air Duct Cleaners Association (NADCA) show that regular duct cleaning can help maintain system efficiency and improve indoor air quality.

Solutions for Cleaner Air

Professional air duct cleaning and inspection should be part of routine HVAC maintenance. Ensuring that your ducts are sealed properly and free of debris helps minimize the spread of pollutants and supports a healthier indoor environment.

Inadequate Air Filtration

Why Filters Matter

Many homeowners underestimate the importance of air filters. Standard HVAC filters primarily protect your system from large particles but often fail to capture finer pollutants like bacteria, viruses, and volatile organic compounds (VOCs). These tiny particles can remain suspended in the air, contributing to poor indoor air quality and potential health issues.

Health Implications

According to the EPA, prolonged exposure to poor indoor air quality can increase the risk of respiratory infections, aggravate asthma, and even affect cardiovascular health. Families with young children or elderly members are particularly at risk.

Upgrading Your Filtration

Using high-efficiency filters (like HEPA filters) or installing an air purifier in conjunction with your HVAC system can drastically improve indoor air quality. Regularly replacing filters ensures your system runs efficiently while capturing harmful particles.

Volatile Organic Compounds (VOCs)

What Are VOCs?

VOCs are chemicals released from everyday products such as paints, cleaning supplies, furniture, and even carpets. While outdoor air pollution often gets attention, indoor VOCs can reach higher concentrations in homes, especially in well-insulated modern buildings like those common in Houston.

Health Risks of VOCs

Exposure to VOCs can lead to headaches, dizziness, eye irritation, and long-term respiratory problems. Children and individuals with asthma are particularly sensitive. The World Health Organization emphasizes that long-term exposure to indoor VOCs can contribute to chronic health conditions.

How to Reduce VOC Exposure

Ventilation is key. Using exhaust fans, opening windows when weather permits, and choosing low-VOC or no-VOC products can significantly reduce exposure. Combining these strategies with HVAC filtration upgrades further enhances indoor air quality.

Poor Ventilation and Stale Air

The Hidden Dangers of Stale Air

Even if your air looks clean, stagnant or poorly ventilated air can be a serious indoor air quality issue. Homes that are tightly sealed to improve energy efficiency can trap pollutants inside, creating pockets of stale air that contain dust, allergens, and microbial contaminants.

Effects on Health and Comfort

Stale air can contribute to headaches, fatigue, and respiratory irritation. Over time, inadequate ventilation can worsen indoor air quality and create an environment where mold and bacteria thrive.

Improving Ventilation

Mechanical ventilation systems, such as energy recovery ventilators (ERVs) or heat recovery ventilators (HRVs), can bring in fresh outdoor air while minimizing energy loss. Even simple solutions like ceiling fans, exhaust fans in bathrooms and kitchens, and opening windows periodically can improve airflow and reduce indoor pollutant buildup.

Pet Dander and Household Allergens

Common Overlooked Allergens

In Houston homes, pets are beloved family members, but their dander can accumulate in carpets, furniture, and HVAC systems. Dust mites, another common allergen, thrive in humid climates like Houston and are often overlooked as a source of respiratory issues.

Impact on Health

Allergens can cause sneezing, coughing, itchy eyes, and even trigger asthma attacks. For families with children or elderly members, controlling allergens is critical for maintaining a healthy home environment.

Practical Solutions

Regular cleaning, vacuuming with HEPA-filter vacuums, and professional HVAC cleaning can help reduce allergens. Installing high-quality air filters and using dehumidifiers can further minimize dust mite populations.

Carbon Monoxide Risks

The Silent Threat

Carbon monoxide (CO) is an odorless, colorless gas produced by malfunctioning furnaces, gas appliances, and water heaters. While often overlooked, CO is extremely dangerous and can be fatal at high concentrations. According to the CDC, more than 400 Americans die from accidental CO poisoning each year, and thousands more require emergency treatment.

Preventing CO Exposure

Regular HVAC inspections and maintenance are critical for detecting and preventing CO leaks. Installing CO detectors near sleeping areas provides an additional layer of safety. Ensuring proper ventilation and timely repairs can protect your family from this silent threat.

Chemical Cleaning Residues

Hidden Pollutants from Cleaning

Many households rely on cleaning products to maintain hygiene, but residues from chemical cleaners can linger in the air or on surfaces, contributing to indoor air pollution. VOCs and other chemical byproducts from these products can irritate eyes, skin, and respiratory systems.

Reducing Chemical Exposure

Switching to natural or non-toxic cleaning products, improving ventilation during cleaning, and using air purifiers can help reduce exposure to harmful chemicals. This simple adjustment can make a significant difference in overall indoor air quality.

Regular HVAC Maintenance: The Key to Healthy Air

The single most effective way to address many of these overlooked IAQ issues is through regular HVAC maintenance. Professional services can:

• Inspect and clean ductwork

• Check and replace air filters

• Test for carbon monoxide leaks

• Evaluate ventilation efficiency

• Recommend air quality improvements, such as purifiers or dehumidifiers

According to industry studies, homes that receive regular HVAC maintenance not only experience improved air quality but also benefit from lower energy costs and fewer system breakdowns.

Why Your AC May Freeze Up Even During End-Of-Summer in West University Place, TX

When the sun blazes, the air feels heavy, and you’re just grateful for a cool breeze from your air conditioner, the last thing you expect is for it to suddenly stop working because it’s frozen solid. It sounds strange—how can something that’s designed to cool your home actually get too cold? Yet, AC freeze-ups are more common than many homeowners realize, and they can happen even when summer is winding down in West University Place, TX.

In our area, the combination of high humidity, intense heat, and unique local weather patterns makes air conditioning systems work harder than most people think. That extra strain can lead to frozen coils, reduced airflow, and, eventually, a complete AC shutdown—leaving you hot, frustrated, and possibly facing costly repairs.

In this post, we’ll break down the main reasons your AC may freeze up during late summer, what signs to watch for, and how you can prevent it. By understanding these causes, you’ll be better equipped to protect your comfort and your investment.

Understanding How Your AC Works — and Why It Can Freeze

Your AC isn’t just a machine that blows cold air into your home. It’s a complex system that relies on a delicate balance of temperature, airflow, and refrigerant pressure to work properly. At its core, your AC removes heat from inside your home and transfers it outside using refrigerant and a system of coils.

When this balance is disrupted—by reduced airflow, low refrigerant, or other issues—the evaporator coil (the part that absorbs heat from your home) can get too cold. If it drops below freezing, moisture in the air will condense on the coil and turn into ice. Over time, this ice builds up, blocking airflow even more, which causes the coil to get colder, creating a cycle that eventually shuts down the entire system.

Why West University Place, TX Homes Are Prone to AC Freeze-Ups

While AC freeze-ups can happen anywhere, the climate and environmental conditions in West University Place make them more likely. Here’s why:

1. High Humidity Levels

According to the National Weather Service, the Houston area—including West University Place—averages a relative humidity of around 75% during summer. This excess moisture in the air makes your AC work harder to remove humidity while also cooling your home. When moisture condenses on your evaporator coil and temperatures drop too low, ice can form quickly.

2. Heavy Cooling Demand

Even at the tail end of summer, daytime highs can hover in the 90s, with heat indexes well above that. This means your AC is still running long cycles to keep your home comfortable. Long run times increase the chance of airflow issues going unnoticed, allowing a freeze-up to happen before you realize there’s a problem.

3. Airborne Dust and Pollen

Late summer in our area can still bring high pollen counts and increased dust levels, especially during dry spells. This debris can clog your air filter faster than usual, restricting airflow and triggering the freeze-up cycle.

Common Causes of AC Freeze-Ups

Several issues can cause your AC to freeze. Some are simple maintenance oversights, while others require professional repair.

1. Dirty or Clogged Air Filter

One of the most common—and preventable—causes of AC freeze-ups is a dirty air filter. A clogged filter blocks airflow, making it harder for warm air to reach the evaporator coil. Without enough warm air moving across it, the coil temperature drops, leading to ice formation.

The Department of Energy recommends checking your AC filter every month during heavy use and replacing it at least every 1–3 months, depending on your system and indoor air quality.

2. Low Refrigerant Levels

If your system is low on refrigerant, it can’t absorb enough heat from your home, which causes the evaporator coil to get too cold. Low refrigerant usually means there’s a leak in your system—a problem that not only causes freeze-ups but can also damage your compressor if ignored.

In fact, the Air Conditioning Contractors of America (ACCA) notes that refrigerant leaks are one of the leading causes of early AC failure, often reducing system efficiency by up to 20%.

3. Dirty Evaporator Coil

Dust, dirt, and mold growth on your evaporator coil act like insulation, preventing the coil from properly absorbing heat. This lack of heat absorption lowers coil temperature and increases the risk of freezing.

Since the evaporator coil is hidden inside your indoor unit, it’s not something most homeowners see or clean themselves. Regular professional maintenance is the safest way to keep this part in top condition.

4. Faulty Blower Fan

Your blower fan moves air over the evaporator coil and into your home. If it’s malfunctioning or running at the wrong speed, airflow drops, the coil gets too cold, and ice begins to form.

This can be caused by worn-out motor bearings, electrical issues, or even an incorrect fan speed setting after repairs or installation.

5. Blocked or Closed Air Vents

Sometimes the problem is as simple as too many closed air vents or blocked registers in your home. Restricting airflow through your ductwork causes a drop in air volume across the coil, setting the stage for freezing.

6. Thermostat Issues

A thermostat that is not reading indoor temperatures correctly may cause your system to run longer than necessary, which can lead to overly cold coil temperatures and ice buildup.

Warning Signs Your AC May Be Freezing Up

Recognizing a freeze-up early can help you prevent major damage. Look for these signs:

• Weak or No Airflow: If air coming from your vents feels weak or nonexistent, ice buildup may be blocking airflow.

• Visible Ice: Ice or frost forming on the refrigerant lines or around the indoor unit is a clear indicator.

• Warm Air from Vents: If your AC is running but blowing warm air, ice may be blocking heat transfer.

• Water Leaks: After the ice melts, you might see water pooling around your indoor unit.

Steps You Can Take to Prevent AC Freeze-Ups

Keeping your AC healthy in West University Place’s climate means paying attention to both airflow and system maintenance. Here’s how you can prevent freeze-ups:

1. Replace Air Filters Regularly

As mentioned earlier, clogged air filters are the top cause of freeze-ups. Regular replacement keeps airflow steady and helps maintain proper coil temperature.

2. Keep Vents Open and Unobstructed

Even if you don’t use certain rooms often, keep at least 80% of your vents open. Furniture, rugs, and curtains should be positioned to avoid blocking airflow.

3. Schedule Annual Maintenance

Professional maintenance helps catch issues like low refrigerant, dirty coils, and blower problems before they cause a freeze-up. The Environmental Protection Agency (EPA) recommends annual servicing for optimal performance and efficiency.

4. Watch for Humidity Issues

If your home feels unusually humid, your AC may not be removing enough moisture, which can be a sign of low refrigerant or coil issues. Addressing this promptly can prevent a freeze-up.

5. Keep Outdoor Unit Clear

Your outdoor condenser needs proper airflow to function correctly. Keep plants, debris, and grass clippings at least two feet away from it to avoid strain on the system.

Can Your Pets Affect AC Performance in Houston, TX?

Living in Houston means being no stranger to heat, humidity, and the need for dependable air conditioning. With average summer temperatures hovering in the 90s and humidity levels often reaching above 70%, a functioning AC system isn’t a luxury — it’s a necessity. For many homeowners, especially those with furry family members, the air conditioner is essential for maintaining a safe and comfortable indoor environment. But have you ever considered how your pets might be affecting your AC system?

Whether you have dogs, cats, or other shedding animals, your pets can impact more than just your furniture and floors. They can also play a surprisingly big role in your HVAC system’s performance and efficiency. In this blog, we’ll take a deeper look into how your pets may be influencing your air conditioner, what you can do about it, and why regular HVAC maintenance becomes even more important when you have animals in the home.

How Pet Hair and Dander Affect Airflow

One of the most common ways pets interfere with AC performance is through shedding. Dogs and cats, particularly long-haired breeds, release large amounts of fur and dander into the air. This debris doesn’t just settle on your carpets — it gets pulled into your home’s ventilation system.

Clogged Filters

Air filters are designed to trap dust, pollen, and other airborne particles. When pet hair and dander build up quickly, filters can become clogged much faster than they would in a pet-free household. A clogged filter restricts airflow, making your AC work harder to cool your home. According to the U.S. Department of Energy, replacing a dirty filter with a clean one can lower your air conditioner’s energy consumption by 5% to 15%.

Strain on the Blower Motor

Restricted airflow forces the blower motor in your HVAC system to run longer and harder to circulate air. Over time, this can lead to wear and tear, reduced efficiency, and even early failure of the motor. The more clogged your filters become, the more your system suffers.

Increased Dust and Contaminants in Ductwork

Pet dander is made up of tiny, even microscopic, skin particles. Unlike pet hair, which is visible and relatively easy to vacuum, dander floats through the air and can settle deep into your ductwork. Once there, it can continue to recirculate throughout your home.

Air Quality Impacts

The American Lung Association reports that poor indoor air quality can contribute to asthma, allergies, and other respiratory issues — especially in children and older adults. Pet dander exacerbates these problems. If it accumulates in your ducts, your air conditioner could be redistributing irritants every time it runs.

System Efficiency

Dust and debris buildup within ducts reduce the system’s overall efficiency. Not only does your AC work harder to cool your home, but it also takes longer to do so. This added workload leads to higher energy bills and puts more strain on your system components.

Pets and Thermostat Use

As much as we love our pets, it’s important to acknowledge how our efforts to keep them comfortable can influence our AC usage. Many pet owners set their thermostats lower during the day to make sure their dogs or cats stay cool while they’re at work.

Energy Consumption

Running your AC longer or setting it lower can dramatically increase your energy use. According to the Energy Information Administration (EIA), cooling accounts for about 12% of the average U.S. household’s total energy expenditures — and that number is often higher in hot climates like Houston. Making temperature adjustments specifically for pets can drive up your cooling costs significantly if you're not careful.

Smart Thermostats and Pet Comfort

One way to balance comfort and efficiency is by installing a smart thermostat. These devices can help manage temperature settings throughout the day while factoring in pet-friendly temperature ranges. For example, most dogs and cats are comfortable at temperatures between 75°F and 78°F, which may not require as much energy as cooling your home to the low 70s.

Pet Accidents and Outdoor Units

Outdoor condenser units are a vital part of your AC system, and unfortunately, they are often accessible to pets — particularly dogs. Pet urine, dirt, and other outdoor messes can negatively impact these components.

Corrosion and Damage

Dog urine is acidic and can corrode aluminum fins and copper coils over time. If your dog tends to urinate near the outdoor unit, it may lead to accelerated deterioration of the condenser. Repairs or replacements of these parts can be costly and are often avoidable with proper precautions.

Blocking Airflow

If pets like to lounge or dig near the outdoor unit, they can accidentally block airflow or cause damage to the surrounding area. It’s essential to keep at least two feet of clearance around the condenser and ensure that it remains clean and free of pet-related debris.

The Importance of Regular HVAC Maintenance for Pet Owners

Having pets doesn’t mean your HVAC system is doomed — but it does mean you should be more proactive with maintenance. Here’s what pet owners in Houston should consider to keep their AC running smoothly:

Change Filters Frequently

If the standard recommendation is to change your filter every 90 days, pet owners should consider changing it every 30–60 days, depending on how much their pets shed. This small habit can drastically improve airflow and system performance.

Clean Vents and Registers

Vacuuming vents and returns weekly can help prevent buildup of pet hair. You’d be surprised how much fur can gather in these spots and how quickly it can be drawn back into the system.

Schedule Professional Duct Cleaning

If you’ve had pets in the house for multiple years or if you notice unusual dust levels, it may be time for a professional duct cleaning. The National Air Duct Cleaners Association recommends having your ducts inspected every 3 to 5 years, especially if you have multiple pets.

Annual AC Tune-Ups

Scheduling annual maintenance is key to catching pet-related issues early. A trained technician from McCann Services can inspect your system, clean coils, check the motor, and ensure everything is operating efficiently. They can also recommend specific solutions tailored to pet-owning households.

Pet-Specific HVAC Accessories

Did you know there are HVAC accessories designed specifically with pets in mind? Here are a few upgrades that can help improve comfort and air quality:

HEPA Filters or Electrostatic Filters

Upgrading to a high-efficiency particulate air (HEPA) filter or electrostatic filter can make a big difference in capturing pet dander and other small particles. These filters are particularly helpful for households with allergy concerns.

UV Air Purifiers

Installed inside your HVAC system, UV air purifiers can reduce airborne bacteria, mold spores, and allergens — including those from pets. They add an extra layer of protection for your home’s air quality.

Dehumidifiers

Humidity in Houston can make your indoor air feel stuffy and uncomfortable. High humidity levels can also intensify pet odors. A whole-home dehumidifier can work alongside your AC system to regulate moisture and reduce that “wet dog” smell.

HVAC Best Practices for Pet Owners

Here are a few practical tips to help Houston pet owners extend the life of their AC system:

• Brush and bathe pets regularly. Less shedding means less hair and dander entering the HVAC system.

• Keep pet beds away from vents. This helps maintain airflow and prevents fur buildup in key areas.

• Use pet gates if necessary. If your pets are curious about the indoor or outdoor units, consider using a barrier to prevent them from getting too close.

• Pay attention to smells and sounds. If you start noticing unusual odors or noises when your AC runs, it may be a sign of pet-related damage or buildup.

Why June Is the Time to Check Your Refrigerant Levels Before the Shortage Hits Hard in Bellaire, TX

Living in Bellaire, TX means you’re no stranger to long stretches of heat and humidity. When it’s hot outside, your air conditioning system isn’t a luxury—it’s a necessity. But what many homeowners don’t realize is that one of the most essential components of your AC system—refrigerant—may be in short supply just when you need it most.

Whether your home is older with an R-22 system or more modern using R-410A or the newer R-454B refrigerants, you could be affected by changing regulations and nationwide shortages. June is the last window to act before demand spikes, prices rise, and supplies dwindle.

Let’s break down why checking your refrigerant levels now is not only smart—it’s essential.

What Is Refrigerant, and Why Does It Matter?

Refrigerant is the substance that cycles through your AC system, absorbing heat from inside your home and releasing it outside. Without it, your AC simply can’t cool your home. It doesn’t “get used up” like gas in a car, but it can leak, and even a small leak can significantly reduce efficiency and cooling performance.

Low refrigerant levels lead to:

• Longer run times

• Higher utility bills

• Poor air circulation

• Risk of system overheating

• Total system breakdown

According to the U.S. Department of Energy, refrigerant leaks can reduce your system’s efficiency by up to 20%—and over time, that adds up to serious money.

Why the 2025 Refrigerant Shortage Is a Real Concern

The HVAC industry is in the middle of a major refrigerant transition. The Environmental Protection Agency (EPA) has mandated the phase-down of hydrofluorocarbon (HFC) refrigerants like R-410A due to their high global warming potential (GWP). Starting in 2025, many systems will switch to newer, low-GWP alternatives such as R-454B.

But here’s the issue: as manufacturers prepare for this switch, production of R-410A is being scaled back, and prices are rising as demand outpaces supply.

Reports from industry insiders show:

• R-410A stockpiles are projected to drop by over 30% by the end of summer 2025.

• R-454B, while cleaner, is not yet widely available, and many systems are not compatible with it.

• Contractors and suppliers are already warning of delays, backorders, and increased service times.

What this means for Bellaire homeowners is clear: waiting until July or August to check your refrigerant levels could leave you at the back of the line during the hottest time of the year.

Signs Your AC Might Be Low on Refrigerant

You don’t have to be an HVAC expert to recognize when something’s off with your system. If you notice any of these signs, you could be running low on refrigerant:

• Your home isn’t cooling as effectively as it used to, even with the thermostat set low.

• Warm air blows out of your vents even when the AC is running.

• The system runs constantly without achieving the set temperature.

• Ice forms on the refrigerant lines or evaporator coil.

• You hear hissing sounds, which can indicate a refrigerant leak.

If you’ve noticed any of these issues, don’t wait—your system might be under strain, and that strain only increases the longer the refrigerant remains low.

Why June Is the Smart Time to Act in Bellaire

June sits right on the threshold of peak summer temperatures in Bellaire. Waiting even a few more weeks could mean:

• Longer wait times for appointments as HVAC contractors book up.

• Higher refrigerant costs as demand spikes and supply thins out.

• System failures during heat waves when your AC is working its hardest.

By scheduling a refrigerant level check and system inspection now, you avoid the last-minute scramble—and get ahead of the crowd. It’s proactive, not reactive.

What Happens During a Refrigerant Check?

A refrigerant level check is part of a professional AC tune-up. When a technician from McCann Services comes to your home, here’s what they’ll do:

1. Inspect the system for leaks – Using electronic detectors or dye tests, the technician will check for any signs of refrigerant escaping.

2. Measure refrigerant pressure – They’ll ensure the system is charged to manufacturer specifications.

3. Evaluate system performance – Technicians assess airflow, temperature differentials, and overall cooling performance.

4. Repair any minor leaks or damages – If a leak is found, repairs can often be made during the same visit.

5. Recharge refrigerant if necessary – Only EPA-certified professionals can legally handle refrigerant. If your system needs a recharge, we’ll top it off safely and correctly.

Regular maintenance—including refrigerant checks—can extend your AC’s lifespan by up to 40%, according to ENERGY STAR®.

What If My System Uses R-22 or R-410A?

If your system still uses R-22, you’re probably already aware that it was phased out in 2020. Supplies are limited to recycled or recovered refrigerant, and it’s increasingly expensive. If your R-22 system is having refrigerant issues, this might be the time to discuss upgrading your equipment.

If your system uses R-410A, you’re in a better position for now—but not immune to the effects of the 2025 transition. You can still get refrigerant this summer, but availability might become tighter later in the season.

Starting in 2025, new AC systems will shift to R-454B, which is not backward-compatible. So if your system is more than 10 years old, you might consider scheduling a consultation with McCann Services to discuss your options ahead of the switch.

Can I Just Top Off the Refrigerant Myself?

Short answer? No. Refrigerant isn’t like windshield washer fluid—it’s a chemical compound regulated by the EPA. Only licensed professionals are permitted to handle, recharge, or dispose of it.

DIY refrigerant recharges:

• Violate federal regulations

• Risk damaging your system

• May result in incorrect levels, which can harm performance and void your warranty

• Can be hazardous to your health if mishandled

Professional AC technicians don’t just “top it off”—they check for leaks, verify correct pressure, and make sure the system is running safely and efficiently.

Preventative Maintenance = Peace of Mind

Refrigerant checks aren’t just about solving problems—they’re about preventing them before they happen. In the Texas heat, a broken AC is more than an inconvenience. It can impact your health, safety, and even your home’s structure (especially if excess humidity leads to mold or moisture damage).

According to the U.S. Energy Information Administration, Texas households use more electricity for air conditioning than any other state—accounting for roughly 18% of their total energy consumption. Keeping your system efficient doesn’t just keep you cool—it saves you money.
