Common A/C problems can become major inconveniences as the heat of summer arrives. Many glitches that don’t draw much attention while the weather’s still moderate may become painfully obvious when your system’s struggling under the kind of cooling load a North Carolina heat wave can produce. They can also make themselves known on the bottom line of your monthly utility bill, as under-performing units often consume excess energy to meet thermostat settings. Most air conditioning service calls involve issues of air flow or temperature shortfalls. Here are four common A/C problems and potential solutions.
Condenser isn’t running
If you hear your indoor blower turning on and off but the fan in the outdoor condenser cabinet doesn’t activate, you won’t get cooling performance. First suspect: A tripped circuit breaker. Reset any tripped breaker switches at the main panel and try the system again. Any other likely cause requires professional help to diagnose and repair.
First, the no-brainer: Is the thermostat set low enough? Try lowering the thermostat five degrees. Also consider the outdoor temperature. If it’s over 100 degrees, your system may simply lack the capacity to keep up with the heat. If not, you may have a dirty indoor evaporator coil, especially if your A/C hasn’t received regular annual maintenance. Unfortunately, most evaporator coils are sealed units and cleaning often isn’t a DIY project. Call your HVAC contractor for service.
When you’re only getting warm air out of the vents but the system seems to be running, check the outdoor condenser, particularly the intake vents in the side of the cabinet. Are they obstructed by weeds, leaves or other vegetation? You need two feet of open space on all sides for proper airflow. If everything looks okay, have a professional check the system refrigerant charge.
Unit cycles on and off rapidly
Again, a dirty or iced-up evaporator coil is a possibility. If this is a longstanding problem, your A/C may be oversized for the BTU requirements of your home.
