Common AC Problems and How to Fix Them

Air conditioning systems are a vital part of home comfort, especially during hot summer months. But what happens when your AC stops cooling, starts making noise, or fails to turn on at all? At East Coast Air Conditioning, we’ve helped thousands of homeowners address the most common AC issues. In this blog, we’ll walk you through typical AC problems, simple DIY fixes, and when to call in the pros.

1. AC Not Cooling Properly

Problem: Your system is running, but the air coming out isn’t cool.

Possible Causes:

• Dirty or clogged air filter
• Low refrigerant
• Blocked condenser coil

Fix: Start by replacing the air filter. If that doesn’t work, check your outdoor unit to ensure nothing is blocking it. If the problem persists, it may be a refrigerant leak—which requires professional repair.

Possible Causes:
