Jeremy was very professional and took the utmost care with the maintenance and repair of my home A/C. He was very thorough and didn’t try to push any services. He gave me my options and left the decision up to me! 10/10 great service.
I like that stay cool does their best to assign the same technicians to you each time. Jeremy was already up-to-date on my house and my systems, so there was no acclamation in order for him to begin service. I will continue to recommend stay cool to anyone that asks.

Outstanding service from start to finish! Stay Cool Climate Control recently installed both our new air conditioning and heating systems, and we could not be happier. The entire team was professional, punctual, and highly knowledgeable. They took the time to assess our home's needs, explain our options clearly, and answer all of our questions.The installation process was flawless. The technicians were respectful of our property, worked efficiently, and left the area spotless. Both systems are running perfectly, and our home has never been more comfortable. If you want top-tier workmanship and reliable customer service, I highly recommend Stay Cool Climate Control!

Had a snake in my air conditioner. Called another company who said I would have to get pest control out to remove the dead snake before they would come out. Called Stay Cool and they came out quickly and removed the snake and got my AC running again. I was so thankful because it was so hot outside. I would recommend this company to everyone. There is a reason they have 5 stars!! Thanks Stay Cool!!

Stay Cool was great to work with. HVAC went out and needed someone quickly as it’s 90°+ out and Travis was here same day to diagnose. Gave a reasonable price for a complete new system and quoted us for repairs if we wanted that route. We opted for a new install and they took care of us the next day and were done in just 4 hours! Overall, great experience and will use them again for any maintenance or repairs.

Stay Cool Climate Control just installed a complete HVAC system at my residence this morning and I have been blown away by the professionalism and respectfulness of their technicians. They answered our questions, cleaned & swept up any mess, and has been just absolutely amazing & friendly. I'm not one to give a whole lot of reviews or complete many surveys, so this experience has made an impact on me.
