The tech was very polite. Answered all of my questions. Was very helpful at giving advice on what I could do to keep the system clean. He was very thorough but quick.

J. got my water heater pilot light going again. It was quick and easy. I maybe could've done it myself, but I am physically challenged. It's good to have affordable help, sometimes!

July 22, 2025 Stay Cool technician Dion came to service my AC unit. He was very professional kind and proficient. He showed me photos of my AC unit inside and up on the roof of my building. He explained everything in detail.

Your staff is not only excellent at what they do but so friendly and nice! I really appreciate the fact that I saw video of the finished job since I am unable to physically climb the ladder to the attic. Thank you again for your professionalism and kindness.

Our ac went out the week before Thanksgiving and we were so stressed out. Stay cool was fast to get someone out for a quote. They were straight forward and upfront about everything. The unit had to be replaced and the one we picked was installed quickly and professionally.

We have had multiple issues with our unit since we moved into our home. Stay Cool has been wonderful to work with going above and beyond to provide exceptional customer service and up to date communication the three times we've had to have service.

Lionel arrived to complete our mini-split maintenance. He was very polite and respectful. He explained his process with us in a very professional manner. He thoroughly cleaned our inside and outside units. We are extremely satisfied with the service.

Anthony was a great repairman. He was courteous and knowledgeable. The office said he would be there next day, but expedited the call when she found out our house was warm and uncomfortable. I need a new unit and will use them in the future. I notified my neighbors and several said they would call them next time their A/C needed repairs. They all were great with outstanding customer service.
