My AC Compressor Won’t Turn On.

Why Is My AC Compressor Won’t Turn On?

1. Make sure the circuit breaker is in the ON position and the thermostat is calling for cooling.

2. Check to ensure the condenser coil is clean and hose it down if needed.

3. Monitor to see if the condenser fan runs and listen to see if the compressor tries to start

If your air conditioner compressor is not working, the problem can often be from the HVAC electronics. However, it can also be a dead compressor but most likely be confirmed by an HVAC professional.

Many small, inexpensive and easily replaceable parts are often breaking down. So it would be a lot cheaper to first replacing those parts than any major components. Also, in many cases, your HVAC system may simply need a thorough cleaning. We don’t recommend any customer to try and do the repair themselves but should leave it for the pros.  But knowing that some customers are technical than others. Here are a few simple steps you can do with caution before calling a certified HVAC company. First, let us talk about the compressor and its function.

What is an Air Conditioner Compressor?

Air Conditioner Compressor

An air conditioner compressor is a part of your air conditioner that helps to cool your room. It can be made up of several different parts, but it all works together to blow cold air into the room and make it feel cooler. The compressor is a major component of your air conditioning system. It is typically located in the outdoor unit among other components which make up the condensing unit.

The role of the compressor is to compress the returning refrigerant as it carries heat out of the conditioned space. This heat then gets dumped into the atmosphere upon reaching the condenser by the use of a condenser fan. During this process, the vapour refrigerant gets converted from its vapour state, into a liquid before leaving the condenser.


Now that all of the above has been physically checked and inspected, you can now determine if power is going to the condenser. Therefore, get in touch with us today and speak to one of our specialists about the problem.
