The air conditioner in your home or business uses a capacitor that is designed to send power or electricity to the air conditioner’s motors. Depending on the type of cooling system you have, you will find there are two major motors, the compressor motor and the blower motor. Without a properly functioning capacitor your air conditioner will not be able to cool your home. Even though the capacitor is a rather small component, when it fails it can have a major effect on your home’s cooling system. Air Supply Heating & Air Conditioning would like to share some of the common signs of capacitor failure.

Air Conditioner Not Blowing Cool Air

When the air conditioner isn’t producing cold air, first try to switch the air conditioner off and then back on. This will help reset the cooling system. When resting your cooling system, double check the thermostat’s settings to rule out the possibility that the thermostat’s setting was somehow accidentally adjusted. If the air conditioner still isn’t running, and you still do not feel any cool air coming from the air vent, most likely the capacitor has failed.

Loud Humming or Buzzing AC Noise

An air conditioner will make a soft humming noise when it is running. When your air conditioner is making a louder humming noise than what is usual or it is making a buzzing noise, this can point to a failing capacitor as well. If your home is feeling warmer or the air conditioner seems to have a hard time starting up along with the noises, this is most likely a failing capacitor.

Air Conditioner Switches Off

If the air conditioner switches off before the cycle was completed, the common problem is that the blower motor capacitor has failed. The second step to the cooling system is the blower, which circulates the cool air through the air ducts and into the home. If the air conditioner was running normally and suddenly shuts off, then this often points to the failure of the blower’s motor capacitor.

Air Conditioner Struggles to Start

If you notice your air conditioner seems to have a hard time starting up, this is often due to a failing compressor motor capacitor. The first component to start the cooling cycle is the compressor. If the compressor isn’t starting, the capacitor is dead. However, if the air conditioner struggles to start then the capacitor is wearing down and needs to be replaced.

Testing an AC Capacitor

If the capacitor is failing or dies, an HVAC technician can come to your home and run a diagnostic or test the capacitors. They will discover if there is any power entering through the capacitor to see if they are still working. They will do a visual inspection of the capacitors as they may have melted or burned out. If the capacitors have indeed failed, they can be quickly replaced and your cooling system restored.
