Why Is My AC Running but Not Cooling?
Seven Usual Suspects
An AC that runs but doesn't cool almost always has one of seven problems: a failed capacitor, a stuck contactor, low refrigerant, a dirty coil, a clogged filter, a bad condenser fan or a thermostat issue.
| Cause | What You Notice | Typical Fix |
|---|---|---|
| Failed capacitor | Outdoor fan not spinning, humming | Replace capacitor |
| Stuck or pitted contactor | Outdoor unit won't start or won't stop | Replace contactor |
| Low refrigerant | Warm air, ice on the copper line | Find and fix leak, recharge |
| Dirty outdoor coil | Weak cooling on the hottest days | Clean the coil |
| Dirty indoor coil or filter | Weak airflow, coil freezes | Clean coil, change filter |
| Bad condenser fan motor | Fan slow or silent | Replace fan motor |
| Thermostat problem | AC won't respond to settings | Recalibrate, rewire or replace |
What Can I Check Before Calling?
Before calling for AC not cooling repair, five checks take five minutes and sometimes fix it.
- Thermostat on COOL, fan on AUTO, set below room temperature.
- Fresh batteries in the thermostat.
- Breakers for the indoor and outdoor units switched on.
- A clean filter, not a gray, dusty one.
- Outdoor unit running with the top fan spinning.
If the outdoor fan isn't spinning, turn the AC off to protect the compressor and call us.

Why Does My AC Cool Some Rooms but Not Others?
Usually an Airflow Problem
An AC that cools some rooms but not others usually has a duct or airflow problem, not a broken unit. Upstairs rooms, bonus rooms and rooms at the end of long duct runs feel it first.
| Hot Room Cause | Fix |
|---|---|
| Crushed or disconnected duct | Repair or replace the duct run |
| Leaky duct joints in the attic | Seal with mastic |
| Too few returns upstairs | Add a return |
| Bonus room over the garage | Add a ductless mini split |
| Closed or blocked vents | Open vents, move furniture |

Is It Worth Fixing an AC That Won't Cool?
Fixing an AC that won't cool is usually worth it when the cause is a capacitor, contactor, fan or cleaning. It may not be worth it when an old system needs a compressor or has an R-22 leak.
- Under 10 years old, small part: fix it.
- 12+ years old, compressor or R-22 leak: compare with replacement.
- Not sure: get a free second opinion.

Why Lowcountry ACs Stop Keeping Up in Summer
Heat Plus Humidity
Lowcountry ACs stop keeping up in summer because they're fighting heat and humidity at once. A system that's slightly low on charge or a little dirty cools fine in May and falls behind in July.
- Design temperature: most systems are sized for about 95 degrees outside; hotter afternoons push them to the limit.
- Humidity load: your AC spends part of its effort pulling water out of the air.
- Dirty coils: pollen and grass clippings choke airflow.
- Sun load: west-facing rooms and big windows heat up fast.
A healthy AC should cool the air about 15 to 20 degrees between the return and the supply vents.

Frequently Asked Questions About AC Not Cooling Repair
Quick Answers
Why Is My AC Blowing Warm Air?
An AC blowing warm air usually has a failed capacitor, a stuck contactor, low refrigerant or a dirty coil. If the outdoor fan isn't spinning, turn the AC off and call.
Can a Dirty Filter Stop My AC From Cooling?
Yes. A clogged filter cuts airflow, which can freeze the indoor coil and stop cooling. Change filters every 1 to 3 months.
Should I Turn Off an AC That Isn't Cooling?
Yes, if the outdoor fan isn't spinning or there's ice on the lines. Running it can damage the compressor.
How Cold Should Air From My Vents Be?
Air from your vents should be about 15 to 20 degrees cooler than the air going into the return.
Why Does My AC Cool at Night but Not in the Afternoon?
That usually means the system is low on charge, dirty or slightly undersized, so it falls behind when the heat peaks.
Can Low Refrigerant Fix Itself?
No. Low refrigerant means a leak. The leak has to be found and repaired before recharging.
How Fast Can You Fix an AC That's Not Cooling?
Many not-cooling repairs are fixed the same visit, because capacitors, contactors and fan motors ride on our vans.
Do You Charge for a Second Opinion?
No. Second opinions on replacement quotes are free.
