How Does An AC Capacitor Work?

An air conditioning system needs a capacitor to start and work well. It is one of the most important electrical parts. A little item called the capacitor is often neglected, yet it is highly critical for starting motors and keeping them running smoothly. When a capacitor starts to fail, the system could not turn on at all, or it can turn on slowly and spew hot air.

It’s easier to find problems early and avoid paying for more expensive repairs if you know how an AC capacitor operates.

What an AC Capacitor Actually Does

A capacitor is a piece of equipment that holds electrical energy and releases it when it is needed. Air conditioning systems use this stored energy to provide motors a little extra power when they start up and to keep them running smoothly once they start.

If the capacitor doesn’t operate, motors can not start, get too hot, or use too much power.

Capacitors for Starting and Running

Most commercial and home AC systems employ a start capacitor, a run capacitor, or a dual run capacitor that works for more than one portion.

A start capacitor sends a rapid, intense burst of energy to the compressor or fan motor to help it start turning. The start capacitor is taken out of the circuit when the motor reaches its working speed.

A run capacitor, on the other hand, stays in the circuit while the system is running. Its job is to help maintain the voltage stable and make the motor run better.

Signs a Capacitor May Be Failing

Capacitors lose their capacity to store a charge over time, especially in hot locations.

Some common signs that something is awry are:

• The AC unit has problems starting or produces a buzzing noise before it turns on.
• The system shuts off without notice.
• The vents blow warm air.
• The outdoor fan isn’t operating well.
• Circuit breakers trip more often than they should.
• Some broken capacitors may show signs of damage, such swelling or leaking, while many fail without showing any signs of damage.

Why Capacitors Break Down More Often in Phoenix

Electrical parts don’t do well in hot weather. Air conditioners in Phoenix have to work harder and run longer than they do in regions with milder temperatures.

Why You Should Hire a Professional to Do the Replacement

Even if capacitors don’t cost much, a good technician should always change them. Even when the power is out, capacitors may still contain energy, and misusing them can be dangerous. Putting in a capacitor that is the wrong size might also destroy motors and impair the life of the system.

Schedule a time for AC servicing in Phoenix

If your air conditioner takes a long time to start, produces unusual noises, or doesn’t cool as well as it should, it might be because of a bad capacitor. If you take care of the problem early, it might not grow worse and your system will stay running well.
