Few things are as panic-inducing as your AC giving out on a hot summer day (which is basically every day in Florida.) When your central air system malfunctions, there are several things you can try before calling in the pros.
Here are a few troubleshooting tips that may save you some time and money.
Check Your Thermostat Settings
If it were set to a higher temperature or turned off by accident, it would be easy to misconstrue it as a broken AC unit. In reality, a quick adjustment of your settings could fix the problem.
If the thermostat is blank, that means it’s likely not hooked up to a C-wire, or common wire, which draws power from the HVAC system. Instead, it’s battery operated. A blank screen could indicate a dead battery. Replace it.
However, if your thermostat is hardwired and the screen is blank or blinking, that’s a problem for a professional HVAC technician to investigate.
Check the AC Unit’s Filter
A clogged filter is one of the most common problems leading to a poorly functioning or nonworking AC unit. When it’s clogged, it hinders the performance of your entire HVAC system. Change the filter every 30 to 90 days. If you check it before then and it looks dirty, go ahead and change it.
Make Sure Your Vents Aren’t Blocked or Crowded
If your AC is turning on but isn’t cooling your house, the problem may be airflow. Check the vents around your home to make sure that they aren’t blocked or crowded. Poor circulation hinders the unit’s ability to cool your home and causes your AC unit to run longer.
Check the Outside Unit for Debris and Vegetation
Sometimes, a poorly functioning AC unit has nothing to do with what’s going on in the house. Examine the outside unit to make sure that it’s free of debris and vegetation. If there is debris, removing it could fix your AC unit problem.
Try to keep three feet of clearance between your HVAC unit and surrounding vegetation to allow for sufficient airflow.
