Common HVAC Problems And How To Avoid Them: Tips From The Pros

April 14, 2023


If you’re a homeowner, you know how essential a reliable HVAC system is to your comfort and well-being. Even the most well-maintained HVAC systems can experience problems from time to time. These issues can be frustrating, costly, and dangerous if not addressed promptly. From clogged air filters to refrigerant leaks and thermostat malfunctions, various problems can impact the performance and longevity of your HVAC system.

Being top-rated HVAC contractors, we’ll cover some of the most frequent issues homeowners face with their heating and cooling systems and share tips from the pros on how to prevent them from occurring in the first place.

Dirty Air Filters

Dirty air filters are one of the most common HVAC problems, affecting the efficiency and performance of the system. Air filters trap dirt, dust, and other airborne particles to keep the air inside your home clean and healthy. Over time, the air filters become clogged, restricting airflow and making the system work harder to maintain the desired temperature. This can cause the system to overheat, leading to component failure and reduced lifespan.

Solution: To avoid this problem, replacing your air filters regularly is crucial, ideally every one to three months, depending on the usage level. Regular air filter replacement can help maintain the performance and efficiency of your HVAC system, improving the air quality inside your home.

Leaking Ducts

Leaking ducts are a common HVAC problem resulting in reduced comfort, increased energy bills, and poor indoor air quality. Signs of leaking ducts include uneven temperatures, drafts, and excessive dust. To detect and fix this problem, inspecting your ducts regularly is essential.

Solution: The solution to this problem is to inspect your ducts regularly and seal any leaks or gaps with specialized duct sealing materials. However, the best solution is to call a professional duct repair service. Additionally, consider adding insulation to your ducts to prevent heat loss or gain and reduce energy consumption.

Refrigerant Leaks

Refrigerant leaks are a severe HVAC problem that can cause reduced cooling or heating capacity, increased energy bills, and even system breakdowns. Signs of refrigerant leaks include hissing or bubbling sounds, ice buildup on the evaporator coil, and reduced cooling or heating performance. To avoid this problem, it’s essential to have your HVAC system inspected and maintained regularly.

Solution: The solution to this problem is to have your HVAC system inspected and maintained regularly by a professional technician. If a refrigerant leak is detected, the technician will need to locate the source of the leak and repair or replace the affected components. In some cases, it may be more cost-effective to replace the entire system rather than repair the individual parts.

Frozen AC Coils

Frozen AC coils are a common HVAC problem resulting in reduced cooling performance, increased energy bills, and even system damage. Signs of frozen AC coils include reduced airflow, unusual noises, and warm air coming from the vents. To prevent this problem, it’s essential to maintain proper airflow and temperature levels.

Solution: The solution to this problem is to maintain proper airflow and temperature levels by ensuring that your air filters are clean, your ducts are sealed and insulated, and your thermostat is set to the appropriate temperature. Additionally, consider installing a programmable thermostat or upgrading to a more efficient HVAC system to reduce the risk of frozen coils.

Thermostat Malfunctions

Thermostat malfunctions are a common HVAC problem resulting in reduced comfort, increased energy bills, and even system damage. Signs of thermostat malfunctions include inaccurate temperature readings, unresponsive controls, and erratic behaviour.

Solution: The solution for this problem is to check your thermostat settings and connections to ensure they are accurate and properly configured. You can also replace your thermostat with a newer, more advanced model that offers better control and energy efficiency. Additionally, you can consider installing zoning controls or upgrading.
