Air Conditioning Repair Tip 2: Is My Thermostat Faulty?
It is important, living in Tucson, that you are able to depend on the reliable, efficient operation of your air conditioning system. Unfortunately, even with a high-quality system and routine maintenance service, there is no way to guarantee that your air conditioning system will always operate properly. There are a lot of different components that make up your air conditioner, and this means that there are also a lot of different things that could potentially go wrong. If your AC won’t cool your home it may be due to a faulty thermostat. Contact the Tucson air conditioning repair technicians at Goettl today if you think that there is a problem with your thermostat.
Do you notice that your home suddenly feels too warm, even though you have your thermostat set to keep it cool and comfortable? This could well be the result of a faulty thermostat. There are many different reasons that your air conditioning system may suffer this problem. It is possible that it is simply unable to accurately read the temperature in your home. In this case, it may need to be cleaned. You can remove the cover and clear out any dirt and debris that has accumulated in there. This may help the thermostat to more accurately read the temperature in your home.
This problem is not necessarily the direct result of a faulty thermostat. In fact, it is possible for your thermostat to be reading the temperature properly, but for your AC to still leave you uncomfortable. If you have the cover of your thermostat off, feel to see if there is any cool air coming from behind it. If there is a cool draft, it is possible for your thermostat to read the temperature of your home as being cool, resulting in less cooling power from your AC. Your thermostat must be placed in a spot indicative of the true temperature in your home in order to operate properly. As you can see, determining if your thermostat is actually faulty can be trickier than you may have thought. Contact the Tucson air conditioning repair technicians at Goettl today to learn more. We can find the exact cause of, as well as the solution to, any air conditioning problems you may have.

After toughing it out for a night I scheduled a service check with Goettl. Jorge came out and I'm so thankful that he was the one to show up. I was greeted at the door with a gift for my doggo and a new flashlight. Jorge took a look at my system and he knew his stuff. Optimal operating temperatures, pressures and the whole works. He took the time to explain it to me, show me the failed parts and even give me a list of options. With those he gave me realistic expectations at each price point.
He was able to work his magic and get my system back online and my house cool again. This isn't my first time calling on goettl and it won't be my last.





I’ll be canceling my home warranty and working directly with Goettl Air Conditioning & Plumbing from now on. Their reliability and customer care are unmatched. I’m very grateful for Jesus’s honesty and dedication highly recommend!

He explained, while he saw no immediate problems. what we might expect going forward, given the furnace's age and condition. After I asked about major component vs. whole-unit replacement, he provided a thorough explanation, and pricing, of options for us to consider.
Very good experience with Jef! Highly recommend!



His experience led us to a solution for our pipes, which saved us thousands and thousands of dollars.
He’s a good man to have on your side

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.
