As the temperatures heat up, chances are that you will want to run your central air conditioning more. Though you want your home to cool down, you don't want cold air running constantly. This can not only be uncomfortable but also cost you money. Here are some of the reasons why your air conditioner keeps running and what kind of air conditioning repair your unit may need.
Dirty filters block airflow. This makes it difficult for your unit to read and adjust the temperature and humidity. Your air conditioning unit will either run all the time because it reads the wrong temperature or cycle on and off. This could make the interior of your home too cold. If possible, check and change your filters to see if the problem improves.
If your thermostat is failing, then that could also cause your air conditioner to stay on or cycle continuously. Your thermostat is reading the wrong temperature or is not reading a temperature at all. No matter how much you adjust the controls, your unit won't stop running. Your air conditioner will act like it hasn't reached the right temperature and keep running.
Dirty Evaporator and Condenser Coils
The evaporator and condenser coils help absorb and disperse the heat from your home. When they are dirty, then the refrigerant cannot absorb the heat. This causes the unit to work harder as it tries to cool your home. Over the winter, dirt, dead insects, dust, and pollution can all accumulate on the coils, so they need periodic maintenance.
If you've made additions to your home, then your air conditioning unit may be unable to cool off the whole area. Certain types of air conditioners will run continuously until all rooms are cooled. A professional air conditioning repair company can send someone out to make calculations as to how big a system you need. You may need a larger unit or need to change to a split system to handle the load.
One of the best ways to prevent problems with your air conditioner is to have AC maintenance performed before the weather warms. That way, repairs can be done before they're truly needed. Another thing to take note of is that it's perfectly normal for your air conditioner to run more often during hot weather. If your air conditioner unit is constantly blowing air, then turn off or disconnect the unit. Call a professional air conditioning repair person to take a look at your system.
