How Can a Bad Capacitor Cause Me to Need AC Repairs?

Your home’s air conditioning system is a complicated piece of equipment. Its main purpose is to remove heat from your home and then exhaust it outside. In order to do that, it uses two fans as well as a compressor—each with their own motor. Attached to each motor is a capacitor that performs an essential function. We wanted to share a little bit about what capacitors are and why they’re important to your air conditioning system. Give us a call here at Goettl Good Guys Air Conditioning if you need any Paradise Valley air conditioning repair services. Otherwise, read on below to learn more.

Paradise Valley Air Conditioning Repair: Bad Capacitors

If you remember the movies Back to the Future, you may recall that one of the key components of the DeLorean time machine was the flux capacitor which required 1.21 gigawatts of power in order to travel through time. Similarly (kind of), your air conditioning system’s capacitors store an electrical charge and then they deliver it to their attached motor to give it a boost of power.

Each motor in your air conditioning system has its own capacitor that is about the size and shape of a can of soda pop. If the capacitors stop working, these are a few of the issues that can happen.

  • AC producing warm air – If your AC is blowing warm air into your home, it could be that the capacitor for your compressor has stopped working. This would prevent your system from getting the correct pressurization of the refrigerant to allow it to absorb heat out of your home’s air.
  • No cooling – If you aren’t getting any airflow from the registers in your floor or ceiling it could be that the capacitor for the indoor fan isn’t working. If this is the case, you will likely hear the outdoor unit turn on but the indoor unit of your AC remains silent. It could be making a buzzing noise which is likely the sound of the motor trying to operate on its own.
