Dalton did a great job! He came out the same day and fixed our issue. He was also super patient and kind in explaining everything.

AC went out on a Sunday and they sent Travis out almost as soon as I called the next morning. I thought the system was shot, but he checked it all out, made the repairs and got it working again. Thanks!!

I can’t recommend Stay Cool enough! I completely understand why they have a 5-star rating.
I had just moved into my new home when my 22-year-old HVAC system failed only two weeks later. They came out quickly, got it running by replacing a part, were upfront with their pricing, and never made me feel pressured. They did let me know the system was at the end of its life and that replacement was something I should start considering, but they left the decision up to me.
They came back out two more times as I weighed my options, and when I finally decided to replace the system, the entire process was smooth from start to finish. Everyone was prompt, professional, knowledgeable, and genuinely kind.
What impressed me the most was that they even took the time to speak with my home warranty company on my behalf even though that’s not something they typically do. Because of their willingness to help, I was able to get some money back, and I truly appreciated them going the extra mile.
A huge thank you to Scott, Dalton, Landon, Peter, Travis, and Mary in the office (and even Dane, the best AI customer service rep lol). It’s rare to find a company that’s not only great at what they do but also full of genuinely good people. If you’re looking for an HVAC company you can trust, Stay Cool is it.

First of all, a HUGE thanks for Stay Cool Climate being able to schedule same day service during the heat wave and the upcoming holiday weekend! Alex came out today and did a great job diagnosing and communicating the issue we were having with our AC. He fixed it up quickly and made a few recommendations with no added pressure. After the work was completed we decided to sign up for the preventative maintenance program, which was an easy decision after the experience we had with this repair. Highly recommend!

My air conditioner went out on Wednesday afternoon, and Stay Cool Climate Control had someone at my house first thing Thursday morning. Dalton was my technician, and he did an excellent job. He was professional, friendly, explained everything clearly, and had my AC up and running quickly. I really appreciated the fast response and great customer service. If you’re looking for a reliable HVAC company, I highly recommend Stay Cool Climate Control!

Stay Cool helped us out in a big way, was there the morning after I contacted them with a technician, helped our existing AC make it a few more days until they could install a new one. All of the technicians and the installers who came were on time or early and always explained everything very well.
