AC went out last night with temps in the mid 90’s. With one call to Jeremy, he had a tech out first thing the next morning. Had me up and running again in less than an hour, and the house is already back to temp in less than 18 hours. Will definitely resume them again…prompt and reliable. Tech was super friendly…he also showed me a quick and simple fix I can do myself to prevent further damage down the road.

Great company, goes above and beyond, they don't money grab, they love pets.

My husband and I just bought our first home, we knew our A/C unit would eventually need replaced, next thing we know it was completely out in the middle of summer.

We reached out to Stay Cool and they showed up on time for both the initial inspection and the installation. Showed pictures of problem areas. Out the door price, taxes included. Very clean and professional. Even fixed our gas water heater exhaust because it was sketchy. Overall above and beyond what we expected.

I would also like to add again, THEY DONT MONEY GRAB! For the size of our home, the standard cheapest unit was a perfect fit. That is exactly what they recommended. They were very understanding of our finances as we just bought this house and even gave us different tips to help make this purchase easier.

We are so happy to know that we will not be having any issues any time soon! Thank you guys for all of your help and Stay Cool! 😉

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.
