Frequently Asked Questions

Why is my AC running but blowing warm air?

The most common cause of “warm air” during an emergency is a failed capacitor or a tripped contactor. The capacitor acts like a large battery that gives the outdoor compressor the “kick” it needs to start. If it fails due to extreme heat, the indoor fan will blow, but the outdoor unit won’t produce cooling. Alternatively, your evaporator coil may be frozen solid. While it sounds counterintuitive, restricted airflow (from a dirty filter) or low refrigerant causes the coil to drop below freezing, encasing it in ice and blocking all heat transfer.

Why is the outdoor unit making a loud buzzing or screeching sound?

A loud buzzing usually indicates that the compressor is stalled or “slugging.” This happens when the capacitor has failed, and the motor is trying to start but can’t, or when liquid refrigerant is entering the compressor (which is designed only to handle gas). A high-pitched screeching, however, is often a sign of high internal pressure or a failing condenser fan motor bearing. In either case, you should shut the system off at the thermostat immediately; continuing to run a noisy unit can turn a $300 repair into a $3,000 compressor replacement.

How can a clogged drain line shut down my entire AC system?

Most modern AC installations include a primary or secondary condensate overflow switch. Because air conditioners pull gallons of water out of the air, they rely on a drain line to move that water outside. If this line clogs with algae or “sludge,” the water backs up into a safety switch. This switch instantly cuts power to the “R” (power) wire of your thermostat to prevent your ceiling or floor from flooding. If your thermostat screen is completely blank and won’t turn on, a clogged drain line is the first thing a technician will check.
