Troubleshooting Your AC (Before Calling for Repairs)
The last thing that any homeowner in a climate as hot as ours wants to encounter is an air conditioner that stops working properly in the middle of the hottest time of the year. Unfortunately, there is just no way in which to guarantee that your air conditioner in Phoenix, AZ is always going to function precisely as it ought to. Air conditioners are mechanical systems, and they operate under a lot of stress in this part of the country. Eventually, you are going to run into trouble.
The good news is that many issues with one’s air conditioner can be resolved quickly and simply. There are obviously a lot of very serious problems that could develop with an air conditioner, but not every instance is going to be terribly serious. Here are a few tips for troubleshooting your air conditioner before dialing our number to schedule repairs.
The Air Conditioner Is Not Blowing Air At All
This is the most alarming situation that you can encounter when trying to cool your home during the summer season. Now, there is certainly a chance that your system has broken down entirely for some reason and that it may need to be professionally repaired. However, there may be other issues causing the problem that you can handle on your own.
The very first thing that you should do is simply check your thermostat. If you have accidentally set the temperature higher than you meant to, or if the system was accidentally switched off, then you are not going to need professionals to resolve the situation! Simply make the necessary adjustments, remind the kids not to fiddle with the thermostat, and get back to living comfortably.
Another item to check is your condensate pump. If your air conditioner does not just drain condensation out of the house, but relies on a pump to get rid of it, it is possible that this pump has malfunctioned. If the reservoir is full of water, a limit switch may be keeping the system to keep it from overflowing.
Finally, double check your circuit breaker. The indoor unit may be running on a circuit that has tripped, and you can fix that problem with a simple flip of a switch. If you cannot find any obvious cause of the issue, then contact us to have the problem diagnosed and resolved.
The System Is Blowing Warm Air
Another issue that you may encounter is warm air coming from the registers in your home. This could be indicative of serious issues like refrigerant leaks or damaged ductwork but, again, it could also be a minor issue that you can handle on your own.
It’s possible that the outdoor unit is off due to a tripped breaker, leaving the indoor unit to blow unconditioned air throughout the house. Again, just check the breaker and reset it as needed. You should double check the thermostat as well. It’s even possible, if you use a heat pump, that you accidentally left the system in its heating mode.
You are not always going to wind up in a best case scenario, of course. When you’re not, count on our team for exceptional air conditioning repairs.
G-O-E-T-T-L it’ll keep you cool but it’s hard to spell.

Update: 12/3/24 - Jacob is great. He fixed the leaking parts on water softener and also checked the water heater to see what can be done with that. He is efficient and very knowledgeable and reviews everything so you understand.

Update: 7/25/24 - had some more work done today. The folks who come to service, install, etc. are great. They know their job, are very efficient and friendly. Today it was Justin and Luis who were installing a new filter system. Looking forward to not have to change filters every month. Thank you, gentlemen, for all the hard work in the heat.

They said I needed to replace my a/c. I was given a choice of 5 units. I liked that the 2nd most expensive would balance the temperature in my house. I get full west in my living room in the afternoon. It is always 10 plus degrees hotter on my sofa, than rest of house. So I paid a fortune and it isn't doing what he said it would. They came back and added another vent to my living room. Better, but still not what I was told. I could saved $10k and got the cheaper model. Don't think I have much recourse to get this fixed. The technicians are very good, too bad their salesmen and products are not up to the same standard.


Blake was absolutely amazing from start to finish. He was friendly, personable, and genuinely took the time to listen to my concerns. He explained everything clearly, provided sound and honest guidance, and never once made me feel pressured. His professionalism and genuine care made it easy for me to trust him and feel confident in moving forward with this company.
Technicians like Blake are the reason customers stay loyal—he definitely deserves a raise. I’m truly blessed to have encountered him today. Thank you, Blake, for your outstanding service!










Thank you!!!




Original order of checking thermostat. And why heat would not kick on right away
It was taking several degrees to heat up the house. Air conditioning works great.
He went and checked thermostat and suggested a new thermostat. $800 for two installed. 👀
He then checked furnace in attic.
The fresh air exchanger was pretty dusty and he could clean it for under a hundred $. I said go ahead because exchanger runs ten minutes per hour to keep fresh air circulating. So price was $99. Still a lot for cleaning a screen.
It seemed to have worked in conjunction with thermostat because it’s been working properly since he left.
Im glad I didn’t spend $800. But only $228 .
Hope thermostat continues to work well
Thank you Jackie.
I still think prices are very high. You can buy and install a thermostat yourself for $175. With a $75 rebate. That’s quite a difference.


I also want to add that Taylor came to service my unit and she was amazing. My dog is usually sketched by most people and she liked Taylor. That's a huge plus.









Thank you Ian for my maintenance today!
March 2, 2024

Andrew is an outstanding representative of the company.
Thanks

We had Edgar come out to inspect our new home today and he did a very thorough inspection. He made sure the unit was checked so when the warranty company comes out we have all information possible. Amazing customer service and very personable
Edgar came back after a warranty inspection was done on the home by the install company. He found errors and was amazing at documentation of the issues. If I could give more than 5 stars I would.
Peter and Josue came out today to do an additional check on our unit with humidity issues. The weather was not conducive to having the outdoor pressures checked and they were very thorough with an interior check. Very professional and knowledgeable.









I would also like to thank Josh for his assistance in the process. He helped us find ways to save money on the additional work that needed to be done. His calm demeanor not only added a professional touch but also helped us heal from the prior experience with the other HVAC company. Thank you, Josh and Jorge, for helping us make the right decision. Jeremy is the bum digidy in a good way.



















I think the guy that was supposed to be assigned to me had problems. My appointment was from 9-1 and Austin was assigned to me at 1:30 and Drove over an hour to get to me.
Now that's 💜
11/24/25 Seems this is an update not its own post. Adam was out to repair our filtration system. No muss no fuss and it was fixed. Awesomely competent guy






Job done quickly and efficiently. Thank you





A special shout-out goes to Pablo, our technician. He was on time, friendly, and extremely knowledgeable. Pablo took the time to explain everything he was checking, walked me through the condition of each component, and gave helpful tips on how to keep our system running efficiently year-round. His attention to detail and pride in his work really stood out. Because of his professionalism and the overall quality of service, Goettl has definitely earned my trust and future business.
Highly recommend Goettl HVAC—and if you can, ask for Pablo!

Veronica and Kdyn did a great job cleaning our ducts too!

I have seen Goettl vans all over town and so I called them.
Got appointment right away and the Technician, Jef Eusepi, took care of our problem.



Call Goettl and was able to get us on the schedule due to a cancellation they had.
Jef Eusepi our tech was fantastic.
He explained everything and showed us pictures of what he was doing and fixing.
Would definitely recommend this Company and Jef.

He was knowledgeable and friendly and was able to flush the tank and get my hot water flowing again. Thanks again...




(Oldest)Jared was great. Got here promptly and fixed it quickly. Lifesaver on a 100+ degree day!










On time, clean, and very thorough with any potential issues.
Thank you.







Chris R came out for our Sadie Membership inspection and review before the cold comes here in TX. He did a fantastic job and really knows his stuff. Thank You!






Mike provided truly exceptional service. From the moment he arrived, it was clear he was extremely knowledgeable; he quickly and confidently diagnosed a very tricky issue that we had with our pipes, explaining everything clearly and answering all of our questions with patience. He also installed our new water heater and did an outstanding job. If you need a plumber who gets the job done right the first time, we highly recommend Mike. Thank you!






The Goettl team has been very professional and helpful to me as their customer. Thank you, Kelli Stoika.
PS… If there would’ve been 6 stars on the scale, that’s what I believe they should’ve received.

Thank you,

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.









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
Customer service and communication for any AC related issues. He is very knowledgeable, personable and trustworthy. I am grateful and satisfied.







They listened to my issue, were very through, checked for leaks, etc. I’ve lived in Lakeway for 30 years, used MANY local plumbers - but Goettl will definitely get all my business moving forward. HIGHLY recommend!
Ty, Wil & Adrian!

Everyone from the Goettl sales representative Christian, Tech / Advisor Josias recommended a HVAC A/C and Heating system replacement. Technicians team Veronica and her partner.
