Top 5 Reasons Your AC Needs Repair (And How to Fix Them)
It’s a sweltering summer day. Your AC’s running non-stop, but the house still feels like a sauna. What’s going on? AC problems are frustrating, but the good news is most issues are fixable—if you act fast.
Let’s break down the top five reasons your AC might need repair and what you (or a professional) can do about it.
1. Your AC Blows Warm Air
You crank up the AC expecting a cold breeze, but instead, it feels like someone’s pointing a hair dryer at your face.
Why it happens:
-
Dirty air filters restrict airflow.
-
Refrigerant levels are low.
-
Compressor issues.
How to fix it:
-
Swap out the air filter—it’s cheap and takes minutes.
-
Check for ice on the coils. If you see frost, turn off the AC and let it thaw.
-
Low refrigerant? Call in an HVAC technician. They’ll diagnose the leak and recharge the system.
2. Strange Noises Are Coming from the Unit
Is your AC clanging, buzzing, or screeching like it’s auditioning for a horror movie?
Why it happens:

Loose or broken parts.
-
Fan blades hitting debris.
-
Motor or belt issues.
How to fix it:
-
Shut off the unit and inspect for visible debris.

Tighten loose screws or bolts.

Nothing’s worse than a dead AC when you’re melting in 100-degree heat.

-
Double-check the thermostat settings. Set it to “Cool” and lower the temperature.

Why it happens:

The AC unit’s efficiency has dropped.
