Fall may be just around the corner, but the days remain long and hot. Few things can put a damper on the final stretch of summer like your AC not working. In this post, we cover 5 common A/C problems to watch out for.
1. Dirty Filters Impeding Air Flow
The air filters in your unit need to be replaced frequently, or in the case of reusable filters, they need to be cleaned frequently. As filters become clogged with dirt, dust and debris, it can prevent proper airflow throughout your unit.
2. Low Refrigerant Levels
Low refrigerant levels will impede the effectiveness of your unit. This chemical, also known as Freon, is responsible for cooling the air within your system. If your unit needs to be recharged with refrigerant, it’s a strong indication you are dealing with a refrigerant leak, which should be located and repaired right away.
Your unit depends on two fans – one that blows indoor air over the evaporator coil to cool the air, and an outdoor fan that conveys the heat absorbed from your home to the outside. Faulty motors, worn belts, dirt and debris or lack of lubrication can cause either fan to stop working properly. This can lead to poor airflow, or in the worst case, compressor failure. Cleaning your A/C unit and keeping outdoor compressors free of leaves, dirt and other debris can extend the life of your fans and overall unit.
4. Frozen Evaporator Coils
Evaporator coils are filled with refrigerant and absorb heat from the air. They need warm air circulating around them in order to function, otherwise they can get too cold and develop a layer of ice on the outside. When this happens, you are likely to get either warm air, or no air at all from your unit.
5. Dirty Condenser Coils
Condenser coils are part of the outdoor unit and expel heat removed from the building to the outside. This process of heat transfer can be impeded when condenser coils become clogged with or covered in dirt and debris. This can result in greater wear and tear on your unit and eventual failure. Regularly cleaning your unit can ensure condenser coils are operating efficiently.
Trust a Professional
An annual tune-up by a professional can extend the life of your A/C unit by many years. In addition to cleaning and inspecting your system, an HVAC technician can help set up a maintenance plan and provide guidance on how frequently to change or clean air filters.
