AC Repair Before Summer: 5 Signs Your Air Conditioner Needs Service

Pittsburgh summers can get hot and humid fast. The worst time to find out your air conditioner isn't working is during the first heatwave, when repair demand peaks. A quick pre-season check can save you from a sweaty emergency.

1. Weak or warm airflow

If the air coming from your vents is weak or not cold, you may have a clogged filter, low refrigerant, or a failing compressor. Start by replacing the filter, then call a pro if it doesn't improve.

2. Strange noises or smells

Grinding, rattling or buzzing usually points to a mechanical issue, while musty smells can mean mold in the system. Both are worth a professional inspection before heavy use.

3. Rising energy bills

A sudden jump in your electric bill often means your AC is working harder than it should due to a developing fault. Servicing it restores efficiency.

More warning signs

• Water leaks or excess moisture around the unit
• The system short-cycles (turns on and off frequently)
• Thermostat readings don't match how the room feels
