Compressor inside an open outdoor AC condenser unit during a replacement

The engine of your air conditioner in Orlando, Florida

AC Compressor Replacement

The compressor lives inside the outdoor unit and pumps refrigerant through the entire system. When it stops working, the air conditioner may still blow air, but that air will not be cool.

AC compressor replacement for Orlando homes

AC compressor replacement is one of the larger repairs a cooling system can need. Orlando Cool Air Solutions makes sure the compressor is truly at fault and helps you weigh replacing it against replacing the system.

Signs of a compressor problem

Outdoor unit hums but does not start
The fan may run while the compressor stays silent.
Tripped breakers
The AC circuit breaker trips repeatedly when the system tries to start.
Warm air from vents
The blower runs indoors but the air never cools down.
Loud clanking or grinding
Harsh mechanical sounds from inside the outdoor cabinet.
Hard starts
The unit struggles, stutters or shuts off shortly after starting.

What compressor replacement involves

Not every compressor complaint is a failed compressor. Capacitors, contactors and wiring can produce very similar symptoms and cost far less to repair, so those are checked first.

If the compressor has failed, replacement involves recovering refrigerant, removing the old compressor, installing a compatible new one, replacing related components as needed, then evacuating and charging the system. On older systems, a full replacement may be the better long term choice, and you will hear that comparison directly.

Compressors in long cooling seasons

An Orlando air conditioner runs for many more hours each year than one in a cooler climate. Keeping the outdoor coil clear of grass, leaves and debris helps the compressor avoid running hot.
