AC Component Guide: Capacitors

While you may use your air conditioning system in Phoenix, AZ throughout much of the year, you likely are not familiar with many of the different components that actually allow that air conditioner to cool your home. That’s fine, of course. You aren’t a professional air conditioning technician, and this isn’t the type of material that most homeowners would choose to study for fun. Even so, we do think that it is beneficial to have a basic understanding of some of the important components of your home cooling system. The capacitors in that system, for instance, make it possible for your AC to operate reliably and successfully.

What Are Capacitors, and What Are They Doing in My AC?

Motor capacitors, including start and run capacitors, as well as dual run capacitors, are electrical components that store energy and put that energy to use when needed. Start capacitors, as you may have guessed, are used when your air conditioning system first starts up. Your air conditioner is going to require the most energy when doing so, which means that it may need a little help to get going successfully. The start capacitor boosts the starting torque in the motor briefly to get it over the hump, so to speak.

Just as a start capacitor helps your air conditioner to start up, the run capacitor helps it to keep running in a reliable manner. They ensure that proper, consistent levels of current are moving through the system, so that your air conditioner does not come grinding to a start. As you can imagine, a failing capacitor of any sort can spell serious trouble for your air conditioner.

If your start capacitor is bad, you may hear your system humming away, without actually starting up. Perhaps it will begin to start up, but fail before it has really gotten going. If your run capacitor is bad, you may hear your system start up, and it may even begin to blow some cool air, but it will cycle off before it should. This short cycling wastes energy and puts a lot of strain on an air conditioning system.

If you suspect the need for any AC repairs, remember that Goettl Air Conditioning is the company to call.

My technician Jorge (George) Gutierrez was out today performing the a/c system check. He did a fabulous job and identified significant issues and concerns for the longevity of my current 12 year old system. He was very knowledgeable and helpful on what my options are and in the end I’ll be getting a new system instead of worrying about the current system failing in our extremely hot temperatures. He was very respectful of my home and my dog was ecstatic to meet him.

Frank identified the need for new faucets in the master bath and discussed my preferences. The type of faucet being replaced is no longer available (mini wide spread) so he had to do some research to come up with a solution. Had to be ordered, not surprisingly, and we appreciate his conscientious performance.

This was my first service with this company and it was a pleasant one. The technicians were professional and polite and quickly resolved a minor scheduling conflict. Interaction with a sales manager for a quote on needed equipment was equally pleasant.

Signed up for the Sadie membership as a a preventative measure to avoid bigger problems down the line. Had my appointment to check my system today and to my surprise the tech discovered a huge gash in my ductwork! Thankfully so because the ductwork up there is a very tight space which I could never squeeze myself into and would’ve gone unnoticed for who knows how long. Huge thank you to Technician Roy Adame for making the trip out on a Saturday afternoon, going the extra mile to fully inspect the system in a tight space, and fully explaining the possible causes of the damage and the impact it would on the system performance. 🙏🏼🤙🏼🫡👏🏼🙂
