How do I fix my central air conditioner?

Here are some tips on how to fix — or at least troubleshoot — your central air conditioner. Start by checking the circuit breaker. Turn it off and back on. If it trips, there’s an electrical problem with either the circuit breaker or the AC unit. Next, check to make sure that the air registers (metal grates through which air enters the room) are open. Check your furnace filter for clogs, and replace if necessary. Finally, clean off your outdoor condenser coils, as even a small dust buildup can cause problems.

If you run into obstacles, don’t hesitate to contact the best central air conditioning pros near you for help.
