The cooling season isn't far off, and no Kansas City homeowner wants to face problems when it comes time to turn on the A/C for the first time. While there are literally dozens of things that could cause your central air not to function properly, there are some very common issues that may cause your air conditioner to fail. Some problems require the attention of an experienced HVAC technician, while others may be minor, something you can correct yourself.

What are the five most common issues you may encounter with your air conditioning unit?

Leaking Freon or refrigerant. Refrigerant is the cooling agent that provides cool air via your air conditioning system. If refrigerant levels are low or you suspect a leak, it will cause your A/C to produce air that isn't quite as cold. In fact, low refrigerant levels often indicate a leak. If you have to have your system recharged, chances are you have a leak. While R-22 refrigerant is being phased out in the U.S., there are other types that are used today that don't deplete the ozone. Most important of all, if a leak exists it should detected and repaired. Faulty wiring. Nearly every homeowner knows that faulty wiring presents a risk of fire. Whether wiring was performed by someone who was not certified or the wiring has simply gone bad due to age, it can trip your circuit breaker or result in no power for your cooling system. Outdoor unit fails to function. If the outside unit of your air conditioning system won't function, it can usually be attributed to a bad thermostat, a substantial reduction in power, or even issues with the contractor who installed it. The inside coil is frozen. This typically indicates an issue with airflow, which may be caused by low refrigerant level, a return air vent that is blocked, or dirty/clogged air filters. Fan on outdoor unit not working. The fan is the component that's responsible for heat transfer from inside your home to the outdoors. If the fan on your outdoor unit isn't functioning as it should, the compressor could overheat because the heat is not properly transferring. This could result in the safety overload tripping, or even internal damage to the compressor. There are some things you can do to ensure your air conditioning system functions efficiently, such as changing the filter frequently. However, the best way to avoid any serious issues or those that may become costly is to have regular check-ups (preventive maintenance) twice each year. In doing this, many minor issues can be detected before they become huge headaches. Regardless of your needs, count on the Kansas City HVAC professionals at Schomburg Heating & Cooling.
