Why is my AC running but not cooling?
Start with a dirty filter, a wrong thermostat setting, or a tripped breaker. If those check out, the cause may be low refrigerant, a failed capacitor, or a frozen coil. A provider can confirm.

Currentseeing Heating & Air is a referral service. The providers in our network are independent local businesses, and they do the air conditioning work. Currentseeing Heating & Air connects Birmingham homeowners with them.
The smartest time to ask for help is when the first sign shows up. A louder hum, weaker airflow, or a higher bill all point to a problem that is still small. Act now and the repair is often simple. Wait through a hot, humid summer and it can turn into a failed part or a dead system. Fill out the short estimate form and tell us what you see. A local provider will follow up to talk through the problem, the visit, and a written quote. You choose what happens next.
Check the thermostat. Set it to cool, and set it a few degrees below room temperature. Dead screen? Replace the batteries.
Next, check the breaker panel. If the AC breaker tripped, reset it once. If it trips again, leave it off. Something is wrong.
Last, look at the air filter. A gray, packed filter chokes airflow. Swap it and see if the air improves.
Some problems are urgent. In a hot, humid summer, they get worse fast. Shut the system off at the thermostat and get help if you notice:
For emergency AC repair, send the estimate form first. Request a callback to check provider availability. Many providers can respond quickly, but hours vary.
An AC rarely quits without warning. It gives hints first. Spot them and the fix stays small.
Vents feel soft, or some rooms stay warm. Causes range from a dirty filter to a failing blower or a duct leak.
Buzzing, rattling, squealing, or clicking is not normal. Each sound points to a different part, so describe it to the provider.
Same habits, higher bill. The system is working harder to do the same job.
The house feels sticky even when the AC runs. The system may not be pulling moisture out.
The unit turns on and off in quick bursts. That wears parts down fast.
Many local homes are slab-on-grade ranches with attics that get very hot. Ducts up there lose cool air before it reaches the room. The system runs longer and wears out sooner.
Storm season adds more risk. Power surges can damage electrical parts. Heavy rain and debris can clog drain lines and strain the outdoor unit. After a big storm, check for odd behavior. Do not wait for a full failure.
The provider starts by asking what you noticed. Then they check the thermostat, filter, airflow, and electrical parts. They inspect the outdoor unit, the coil, and the drain line.
You should get a plain explanation of the cause. Then a written quote with parts and labor. You decide before any work starts.
These small electrical parts help the motors start. They fail often in heat, and replacing them is usually quick.
Humid weather grows algae in the line. Water backs up and can shut the system down or stain a ceiling.
If the outdoor fan will not spin, the system overheats. A motor swap is a common fix.
Low refrigerant means weak cooling and a frozen coil. A leak needs finding and sealing, not just a top-off.
Busy home? Say so when you request the estimate. Tell the provider about work schedules, school runs, pets, and naps.
Ask how long the visit should take. Ask if parts are on the truck or must be ordered. Small repairs can often fit into a short window. Larger ones may need a planned block of time.
Repair is usually the answer for a young system with one failed part. Replacement is worth a look when the unit is old, repairs keep stacking up, or the cost of the fix is close to the price of new equipment.
Ask the provider to compare both on paper. Replacement has its own page if you want to read more.
Good providers answer these clearly.
Change the filter on a schedule. Keep leaves and debris off the outdoor unit. Pour water in the drain line opening now and then if the provider suggests it. Book a HVAC service check before summer, not after the first hot week.
Catch it early. Your heating and cooling system will thank you.
The provider finds the real cause of the warm air, noise, or shutdown before suggesting any repair.
You get parts and labor in writing, so you can decide before work starts.
Capacitors, contactors, fan motors, drain lines, and more are handled by independent providers.
Tell the provider about your routine so the visit fits school, work, and pets.
Prices vary by home, part, and provider. These are typical U.S. ranges for common AC repairs. They are only a guide. Always ask for a written quote before work starts.
| Repair item | Typical range | Notes |
|---|---|---|
| Diagnostic visit | $75 – $200 | Often applied toward the repair if you go ahead |
| Capacitor or contactor | $120 – $400 | Common heat-related failure; quick fix |
| Drain line clearing | $100 – $300 | Common in humid weather |
| Thermostat replacement | $120 – $350 | Depends on smart or basic model |
| Fan motor replacement | $400 – $900 | Indoor or outdoor; varies by unit |
| Refrigerant leak repair | $250 – $1,600 | Depends on leak location and refrigerant type |

Treat smoke, a burning smell, water near electrical parts, or repeated breaker trips as urgent. Turn the system off and request help. A hot home with vulnerable people is also urgent.
It depends on age, repair cost, and how often it breaks. A single failed part on a fairly young system is usually worth fixing. Ask for a repair and replace comparison in writing.
