Nothing is more aggravating than a malfunctioning air conditioner. Over time, the air conditioner can stop cooling as it should, which typically means you need to call for a repair. However, there may be some things you can check that can solve the problem. Here are some areas to check before you call in your HVAC technician.
Clean Debris from Outdoor Unit
One area to check is the outdoor condenser unit. If your air is not cooling, there could be some debris built up around the area preventing proper airflow. Over time, cut grass, fallen leaves, and other debris can collect around the unit and clog the unit. The system needs clear airflow to function. In addition, check around the unit to see if you need to cut the grass or pull weeds that have grown up around the area. Also, check inside the unit. Look at the fan mechanism to ensure nothing has fallen through the grates and gotten stuck. This can prevent the fan from turning, which will burn up the entire system.
Make Sure the HVAC Breaker Is On
If you notice something odd with your air conditioner, make sure the HVAC breaker is in the on position. Most HVAC systems require more than one breaker in a home. It is possible that one of them tripped at some point. To check this, locate the breaker box in your home and open the door. Look for the breaker labeled HVAC air conditioner, furnace, and any others associated with the system. Turn them all off then back on. Wait a few minutes, then check to see if the air conditioner will come on.
Make Sure the Thermostat Works
If you still do not have cool air from your air conditioner, make sure your thermostat is working correctly. Digital thermostats will blink or not have anything on the readout if they are malfunctioning. You may only need a simple battery change. If the battery is not the problem, you may need to replace the thermostat. It is not unusual for thermostats to eventually wear out. If you are not comfortable doing this yourself, your HVAC technician can do this for you.
If none of these solutions work for you, you may have a deeper issue that only a professional can take care of. Be sure to note when your air conditioner stopped cooling and whether or not you heard any odd sounds at the time. This will help diagnose the issue more quickly.
