The Top HVAC Repairs in Texas Homes (and How to Prevent Them)

When it comes to maintaining a comfortable home in Texas, your HVAC system is essential. Whether it’s the heat of summer or the chilly winters, your HVAC system ensures that your home stays cool in the heat and warm in the cold. However, just like any mechanical system, HVAC units are prone to issues, and in Texas, the extreme weather conditions can take a toll on these systems. At D-N-D Services, we’ve been helping homeowners in Rockwall and surrounding areas since 1997, providing HVAC services that keep your system in peak condition. Here are the top HVAC repairs we often see in Texas homes and how you can prevent them.

1. Dirty Air Filters

One of the most common HVAC problems in Texas homes is dirty air filters. Air filters are essential in trapping dust, dirt, and allergens, preventing them from circulating through your home. However, over time, these filters can become clogged, restricting airflow and causing your system to work harder. This not only makes your HVAC system less efficient but can also lead to more expensive repairs down the line.

How to Prevent It:

1. Replace your air filters regularly. Depending on the type of filter and your home’s environment, filters should be replaced every 1 to 3 months.
2. Consider upgrading to high-efficiency filters. If you have allergies or pets, high-efficiency filters can help trap smaller particles, improving your indoor air quality.

2. Refrigerant Leaks

Your HVAC system relies on refrigerant to cool your home. When there is a leak, the refrigerant levels drop, causing the system to overheat and potentially fail. Low refrigerant levels are one of the most common causes of HVAC system breakdowns. In Texas, with the long and hot summers, a loss of refrigerant can leave you sweating and scrambling for repairs.

How to Prevent It:

1. Schedule annual HVAC inspections. A trained technician can check your refrigerant levels and detect any leaks before they become a major issue.
2. Don’t ignore poor cooling performance. If your system isn’t cooling as effectively, this could be a sign of a refrigerant leak. Early detection is key to preventing costly repairs.

3. Frozen Coils

Frozen coils can occur when there is insufficient airflow over the evaporator coils or when the refrigerant levels are too low. When the coils freeze, it can lead to system failure, causing a significant inconvenience, especially in the summer. Texas heat can make this problem even more frustrating as the system struggles to keep up with high cooling demands.

How to Prevent It:

1. Keep the air filters clean. A clogged air filter can block airflow to the evaporator coils, causing them to freeze.
2. Get your system serviced regularly. Preventative maintenance is crucial to avoid coil freezing and other performance issues.
3. Ensure your home’s airflow is unobstructed. Avoid blocking vents with furniture or drapes, and make sure the outdoor condenser unit is free from debris.

4. Thermostat Malfunctions

The thermostat is the brain of your HVAC system, controlling when your system kicks on and off based on the temperature you set. If your thermostat malfunctions, it can lead to inconsistent temperatures in your home, or the system might not turn on at all. While thermostats can last for years, wear and tear or wiring issues can cause problems.

How to Prevent It:

1. Check your thermostat settings regularly. Ensure it’s set to the desired temperature and mode (cooling or heating).
2. Consider upgrading to a smart thermostat. Smart thermostats allow you to control your home’s temperature remotely, improve efficiency, and provide maintenance reminders.
3. Schedule a professional check-up. If your system isn’t responding properly, a professional HVAC technician can check the wiring and recalibrate the thermostat.

5. Leaking Ductwork

Ducts carry cool or warm air throughout your home, but they can sometimes develop leaks. Leaky ducts can lead to air loss, making your system work harder and increasing your energy bills. In Texas, with the extreme temperatures, leaky ducts can significantly impact your comfort, especially if your HVAC system is trying to maintain an efficient temperature.

How to Prevent It:

1. Have your ducts inspected. Regular maintenance can identify areas where your ducts may be leaking or damaged.
2. Seal any gaps or leaks. If you notice any air leaks around your ducts, they should be sealed immediately to prevent air loss.
3. Consider duct replacement. If your ducts are old or severely damaged, replacement might be necessary to ensure optimal performance.

6. Compressor Problems

The compressor is the heart of your air conditioning system. It circulates refrigerant through the coils, allowing the system to cool the air. If the compressor breaks down, your HVAC system won’t be able to cool your home effectively, and it may require costly repairs or even a full system replacement. In Texas, where air conditioning is a necessity, this issue can be especially urgent during peak summer months.

How to Prevent It:

1. Schedule regular HVAC maintenance. Regular service helps detect problems with the compressor early and prevents major breakdowns.
2. Ensure proper system operation. If your HVAC unit is working harder than usual or producing inconsistent cooling, it could be a sign of compressor issues. Immediate attention can prevent further damage.

7. Blower Fan Problems

The blower fan is responsible for circulating air through the ducts and into your living spaces. If the blower fan is malfunctioning, your system may not produce enough airflow, resulting in uneven temperatures or total system failure. In Texas, where air conditioning is essential for comfort, blower fan issues can leave you sweltering.

How to Prevent It:

1. Replace air filters regularly. Clogged filters can strain the blower fan and cause it to malfunction.
2. Ensure proper maintenance. Regular maintenance can prevent wear and tear on the blower motor, ensuring it functions properly.
