AC Problems: Faulty Capacitors
Wouldn’t it be great, particularly in as hot a climate as ours, to know that no problems would never befall your air conditioning system? As those of us living here in the real world know, of course, this goal is tragically impossible. An air conditioner is a mechanical system with many moving parts and electrical components. Occasional operational problems are a certainty, not a possibility. Eventually, you are going to require professional air conditioning repair in Chandler, AZ. Contact us when you do.
As we mentioned above, there are a lot of different moving parts and components in any air conditioning system. Any problem with any one of these components is all that it takes to cause serious operational issues with your AC. Left unresolved, such problems could wind up doing real damage to the system. One problem that you may encounter is a failing capacitor. In today’s post, we’ll take a peek behind the curtain to discuss what capacitors do, and how a failing capacitor can affect your system.
Start Capacitors and Run Capacitors
A start capacitor is a device that helps your air conditioner to start up. It takes more energy to start a mechanical system up than it does to keep a mechanical system running, so getting an air conditioner running can require a bit of a boost. It is the start capacitor’s job to provide the system with the extra juice that it needs to kickstart its cooling cycle.
A run capacitor, on the other hand, does not provide an extra jolt of energy. Instead, it helps the system to maintain a charge, even and unvaried, in order to keep the system running properly. There is no point in getting your air conditioner up and running if variations in power levels are going to leave it shutting right back down again anyway, right?
Problems Caused By Faulty Capacitors
As you can imagine, a problem with your start capacitor is going to negatively affect the air conditioner as it tries to start up. The system may develop a severe case of hard starting, wherein the compressor will get going only to grind to a halt. Hard starting puts serious strain on the system that can lead to costly damages, and a hard start kit may be required to help your system get off to a smoother start if the capacitor alone is not enough to do the job.
If the problem lies with your run capacitor, then the air conditioner is going to get running just fine. Unfortunately, it is not going to stay running just fine. The system will start up, but may run only briefly before cycling back down. A faulty run capacitor is one of the common causes of short cycling, and short cycling drives up energy costs while also putting your system at risk for serious operational damages.
If you suspect that you have a problem with your capacitor(s), or any other issues with your air conditioner should develop, contact us right away. You really do not want to ignore problems of any kind with your AC. We’ve seen people do it before, and it only leads to big headaches down the way.

I highly recommend Goettl Air Conditioning and Plumbing! Shane Smith, their plumbing service technician, provided outstanding service when we needed a new water heater.

Oh, and he even brought a Sadie dog toy for my pups! 😁

Stacy arrived today. He was super knowledgeable and interested in answering our questions (which were abundant). Very friendly and not in any hurry to leave. He took his time to explain what he was doing. He pointed out a dangerous situation with our surge protectors. We had fried wires! We ended up having them replaced right on the spot. We were so impressed with him that we will be requesting him next time we're due for our routine check up. Thank you,
Stacy!
James Jacobson was outstanding with his knowledge and took his time explaining every detail.

This past week our service technician was Andrew Morgan and he is such a friendly, knowledgeable, and skilled technician. He spent time making sure the job was done correctly and he explained it in terms that I could understand. Not only is our unit functioning even better than before, I also gained knowledge of how the system works.













I highly recommend Goettl as this is the second time l've used them in less than a year. (2 seperate issues)... and I highly recommend them..anytime and anyday.
They have exceeded to top any expectations I could have ever had with any company.


Jerry also noticed our water pressure was low after flushing toilet then trying to wash hands in bathroom sink which were so he suggested a new pressure regulator as we have had a new better water conditioning system installed. We now have the best water pressure even when using a shower and kitchen sink faucet at the same time. Also Jerry is a master plumber and we appreciate his knowledge and experience. Will definitely call Goettl again when a plumber is needed.

Darean Guerra today. He arrived on time and took the time to explain what he was going to do. He was very knowledgeable which helped me trust what he was doing. He left his work area clean. I am very pleased with his work.




Now we have a new flange, installed correctly, and ready for the new toilet!







The company is installing a tankless heater and the customer service is outstanding.
I recommend Geottl to all!


They made sure my carpet was covered and when they were all through they cleaned up perfectly
I would recommend your company to anyone looking to put in a new air conditioner.
Thank you so much for all you did for me.
Sincerely, June Jones

And I would highly recommend the company and the quality technicians like Jarod.
Jarod is the go to if you want excellent
