Cooling Problems: Is My Thermostat to Blame?
Considering the intense heat of our summer season, ensuring optimal performance from our air conditioners is crucial in the Southwest.
Various factors can contribute to subpar cooling performance. Sometimes, the air conditioner isn’t the root cause; the thermostat is the culprit. Your thermostat is crucial in regulating your home cooling system’s operation.
Recognizing signs of thermostat issues is essential to maintaining a comfortable home environment. If you suspect your thermostat is causing cooling problems, you may want to consider the following.
The Impact of Thermostat Placement
Although it might seem like a minor detail, the placement of your thermostat significantly affects your cooling system’s performance. Incorrect placement can lead to inaccurate temperature readings and inefficient cooling.
Your thermostat should be positioned away from direct sunlight, drafts, and heat sources such as windows, doors, and appliances. Poor placement can cause your air conditioner to cycle on and off too frequently or not enough, leading to inconsistent indoor temperatures and higher energy bills.
Why Placement Matters
When a thermostat is exposed to direct sunlight or drafts, it can give false readings to your cooling system. For instance, if placed in a sunny spot, the thermostat might register a higher temperature than the actual room temperature, causing the air conditioner to overwork.
Conversely, if located near a drafty area, it might read lower temperatures, resulting in inadequate cooling. Strategically placing your thermostat in a central location, away from these influences, helps ensure accurate temperature regulation and efficient cooling performance.
Regular Maintenance for Optimal Performance
Keeping your thermostat clean and well-maintained is essential for accurate operation. Dirt and debris can accumulate over time, interfering with the thermostat’s sensors and leading to incorrect temperature readings. Regularly dusting and cleaning your thermostat can prevent these issues and maintain efficiency.
Simple Maintenance Tips
To keep your thermostat functioning properly, gently clean it with a soft brush or cloth to remove dust and debris. Ensure that the area around the thermostat is also free from obstructions affecting airflow and temperature sensing.
Additionally, check the thermostat’s wiring and connections periodically to ensure they are secure and in good condition. Simple maintenance steps like these can significantly improve your cooling system’s performance and extend its lifespan.
Choosing the Right Thermostat for Your Needs
The type of thermostat you install can greatly impact your cooling system’s efficiency and your overall comfort. Various thermostat options are available, each with its features and benefits. The key is to choose a thermostat that suits your lifestyle and preferences.
Smart Thermostats
Smart thermostats are becoming increasingly popular due to their advanced features and convenience. They allow you to control your home’s temperature via smartphone apps remotely, set schedules, and even learn your temperature preferences over time. A smart thermostat can enhance your cooling system’s efficiency and provide greater control over your indoor climate.
These devices often come with energy usage reports and tips, helping you to identify patterns and adjust settings for optimal savings. Additionally, many smart thermostats integrate with other smart home devices, offering seamless automation and improved home comfort.
Programmable Thermostats
Programmable thermostats offer flexibility by allowing you to set different temperatures for various times of the day. It can lead to energy savings, as you can reduce cooling when you’re not home or during the night when temperatures are typically lower. Ensuring your programmable thermostat is set correctly can help you maintain a comfortable home while reducing energy consumption.
Moreover, these thermostats are ideal for maintaining a consistent temperature schedule without manual adjustments, making it easier to adhere to energy-efficient practices. You can enjoy a comfortable environment while minimizing energy use by programming your thermostat to cool down the house just before you wake up or return from work. In regions with extreme temperatures, this can also help extend the life of your HVAC system by preventing overuse.
Signs Your Thermostat Needs Attention
Recognizing when your thermostat is malfunctioning is crucial to preventing larger issues with your cooling system. Here are some common signs that your thermostat may need attention:
Inconsistent Temperatures
If different rooms in your home have varying temperatures, your thermostat might not accurately control your system. It can happen if the thermostat is placed in an area that doesn’t represent the average temperature of your home, such as near a drafty window or in direct sunlight.
Uneven temperatures can also result from poor thermostat calibration or an aging device that no longer accurately measures temperatures. You might need to relocate your thermostat or upgrade to a more advanced model to resolve this. Ensuring the thermostat is centrally located and away from heat sources can help maintain a more consistent temperature throughout your home.
Unresponsive Controls
Difficulty adjusting the temperature or unresponsive controls can indicate a problem with the thermostat. This issue might stem from faulty wiring, dead batteries, or a malfunctioning interface. In some cases, dirt and dust buildup inside the thermostat can interfere with its internal components, leading to unresponsiveness.
Additionally, an outdated or damaged thermostat may need help communicating effectively with your HVAC system. If you encounter this problem, check the battery and clean the unit. If these steps don’t help, consider a professional inspection or replacement to restore proper functionality.
Constant Running or Short Cycling
The thermostat might give incorrect signals if your air conditioner runs continuously or turns on and off frequently. This condition, known as short cycling, can strain your cooling system excessively, leading to increased wear and tear and higher energy bills. Short cycling can be caused by a miscalibrated thermostat, incorrect temperature settings, or issues with the thermostat’s location.
For example, a thermostat near a heat source can cause the system to cycle on and off rapidly. To address this, ensure your thermostat is properly calibrated and positioned. If the problem persists, consulting with a professional HVAC technician can help diagnose and fix the underlying thermostat issues, ensuring efficient and reliable operation of your air conditioner.

If you notice any of the above signs, it’s time to call a professional HVAC technician to diagnose and fix the problem.

Update 4/21/25 - Mike did a wonderful job. Made suggestion to keep my system running well for more years to come.
‐---------------------
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

Not Plumbing
Goerttl made repair experience not so painful
Support Military
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.



Sally






Thank you,
Greg Sanches





















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.
