Air conditioner doesn’t cool?
Air conditioner doesn’t cool
A central air conditioner that runs but doesn’t cool may just need to be cleaned. Plan to do this on a relatively warm day. Follow the instructions in your owner’s manual.
- Before you begin, turn off the power to the unit. There is normally a shut-off or disconnect panel on the house wall next to the outdoor compressor. Otherwise, shut off the air conditioner’s 240-volt circuit at the main electrical panel.
- Rake leaves and debris away from the outdoor condenser.
- Remove any protective grille or cover from the condenser’s fins.
- Use a soft brush to clean dirt and debris from the fins, and then vacuum them with a brush attachment (be careful not to damage the fins).
- Unscrew and lift the top grille off the unit, if possible. If the fan is attached to the grille, be careful not to pull any wires loose.
- From inside the unit, hose down the fins (protect the wiring and motor with plastic sheeting). If your owner’s manual calls for lubricating the motor, do that now—but don’t overlubricate.
- Reassemble the unit.
- To test it, turn the power on and set the thermostat to turn the unit on. Let it run for a few minutes, and then feel the two pipes that connect to the condenser unit (slide any insulation back). One should feel warm, the other cool. Otherwise, call an air-conditioning technician—the refrigerant may need to be recharged.
Important note: Avoid straining an air conditioner’s compressor by waiting at least five minutes between turning it off at the thermostat and turning it back on.
How to choose an air conditioning contractor
The best way to choose is based on brand, reputation, tenure and price.
”Very painless; everyone was nice and very thorough. A great experience from the very start.”
“The crew did an excellent job installing our new unit and getting us back on so we could have heat that night.”
“Extremely pleased with the professionalism and the courtesy of the men that installed the unit.”
“My technician, Kelly, was so respectful and I didn’t even have to ask questions. He proactively showed me what was wrong and what he needed to do to fix it for me. I am in my 70’s and it was nice to be treated with such kindness and understanding from him. I couldn’t be more pleased with the work they do for me and they always clean up after themselves, I never have to go behind them trying to pick up a mess when they are gone like I have other companies.”
“It’s a great feeling to have someone come out twice a year and maintain my furnace and a/c especially since I would have no idea where to start. These guys are so professional and courteous and do a great job. They are always on time and I know I can count on them to do the job right!’
