Troubleshooting for A/Cs

Troubleshooting for A/CsIf something’s wrong with your air conditioner, is it anything you can repair yourself? Frankly, the list of DIY fixes for central A/C problems is extremely limited. High voltage and toxic refrigerant pose safety issues and exacting technology incorporated in today’s units requires the specialized expertise of a qualified HVAC service technician.

Still, sharpening your A/C troubleshooting skills can help isolate a problem and, most importantly, accurately communicate it to the field technician. Here are some common issues you might notice, as well as the typical causes a qualified service person will want to investigate.

Unit Doesn’t Turn On

Make sure your HVAC thermostat is switched to the “on” position and set to cooling mode. The temperature setting should be at least 5 degrees below present room temperature. If the system still doesn’t cycle on, check for any tripped circuit breakers in your main electrical panel. If you find one, point it out to the arriving HVAC technician.

Insufficient Airflow

If you’re getting cool air — just not enough of it — check the air filter. If it appears dusty and dirty, here’s your one and only opportunity for a do-it-yourself solution: Try installing a new filter. If that doesn’t resolve the issue, call for professional help and mention that you’ve already replaced the filter.

Air Not Cool Enough

If the outdoor temperature’s over 100 degrees, you may be getting all the coolness your A/C can deliver. All units have a finite capacity for heat removal. Close curtains and utilize ceiling fans to assist the air conditioner. If the temperature outside’s not that extreme, poor cooling performance may be due to low refrigerant level or dirty coils — issues that require professional diagnosis and repair.

Water Leakage

Water on the floor around the indoor air handler unit usually indicates an overflowing condensate drip pan. An air conditioner produces gallons of condensate per day. To prevent significant water damage, turn off the unit and call your HVAC contractor immediately to unclog the condensate drain system.
