If your air conditioning system isn’t cooling properly, there are some easy things you can do to troubleshoot your system before you call for repairs.
Air Conditioner Doesn’t Turn On
If your air conditioning system will not turn on, the most likely causes are a blown fuse or circuit breaker, a faulty thermostat, or an internal switch problem. Make sure your thermostat is set to “cool” instead of heat or off. Make sure the thermostat is set below your existing room temperature. Check your circuit breaker for a blown fuse. If you find one, replace the fuse and reset the circuit breaker. If your air conditioner still doesn’t turn on, call a technician to find AC repair today.
Poor Air Flow
Improper air flow typically results from a dirty air filter or blocked air duct. Both can cause poor air flow into your home. First, check your filter to see if it’s dirty, and if it is, replace it. Next, inspect your ductwork to look for ducts that are damaged or disconnected. Lastly, check your register dampers on room vents to make sure they are open. You may not be able to reach your ductwork in the basement, crawl space or attic, so you’ll need to contact an AC technician who can do a physical inspection.
Compressor Turns On and Off Frequently
If your compressor cycles on and off too frequently, this can be caused by a refrigerant leak, faulty thermostat, frozen coils, or a cooling system that too large for your home. First, check for a dirty air filter and faulty thermostat. If your system has a refrigerant leak, frozen or bent coils, or an oversized air conditioning unit, you’ll need to contact an AC technician for professional service and repairs.
