I had a great experience with Stay Cool! They were able to come check my heater the same day I called, and checked all of the heating and cooling systems. I needed a new water heater and furnace - I didn’t feel pressured or like they were trying to upsell. Two days later, Dalton and Neil came to replace those two systems. Everyone I talked with was very professional and knowledgeable. I would absolutely recommend Stay Cool!

Definitely a company I will keep in my pocket for future HVAC services.

Travis , the technician, came out in very polite and professional and identified 2 problems I was experiencing with my furnace. The last few days have been very chilly. He stated what was needed and the price it would involve. With recommendations to plan on if other problems arise. He had to gather equipment needed to get the repair done he was quick and fastidious in his service and informed me when it was completed. Was very happy with the results. My furnace is running again and I’m warming back up. Thank you Stay Cool HVAC for you service.

Jake and Trey were fantastic. Highly skilled and efficient and super nice dudes. We have used Stay Cool multiple times now including a furnace install. Their quote was spot on, they showed up when they said they would. Great experience. Travis was also super helpful in navigating a new furnace. We will be using them again when our other furnace finally dies. Thank you!
