This was my first experience with Stay Cool and I’m very pleased. Dalton installed a new humidifier and performed a spring maintenance checkup on a neglected air conditioner. He was prompt, professional, courteous and had the parts necessary for the identified repairs. I highly recommend.

Both techs were awesome. They were nice and answered all my questions. I would recommend this company to anyone. The out water heater went out called and the next day they were out and had it replaced. Job well done.

Furnace decided it was unhappy with the quick shift back to winter temps, and gave no heat. I scheduled an appointment online, and within 2hr Travis arrived. Problem part was quickly identified and replaced getting heat flowing again. Very impressed with their response and service overall. Great job!

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!
