Hear from Our Satisfied Customers

First of all, a HUGE thanks for Stay Cool Climate being able to schedule same day service during the heat wave and the upcoming holiday weekend! Alex came out today and did a great job diagnosing and communicating the issue we were having with our AC. He fixed it up quickly and made a few recommendations with no added pressure. After the work was completed we decided to sign up for the preventative maintenance program, which was an easy decision after the experience we had with this repair. Highly recommend!

My air conditioner went out on Wednesday afternoon, and Stay Cool Climate Control had someone at my house first thing Thursday morning. Dalton was my technician, and he did an excellent job. He was professional, friendly, explained everything clearly, and had my AC up and running quickly. I really appreciated the fast response and great customer service. If you’re looking for a reliable HVAC company, I highly recommend Stay Cool Climate Control!

Stay Cool helped us out in a big way, was there the morning after I contacted them with a technician, helped our existing AC make it a few more days until they could install a new one. All of the technicians and the installers who came were on time or early and always explained everything very well.

Travis did a good job of explaining what the issues were and giving me options. He left it up to me as far as what I wanted to do instead of pressing into a decision. Would recommend.

Very impressed with the young man that came out he put covers over his shoe. He was very professional and I look forward to seeing him in the fall. I think the price they charge was extremely fair. I didn’t think they were trying to push something on me, I’ve used them before I highly recommend them.

Stay cool Climate control has been so great to work with. Alex was our technician and he went above and beyond the Call of duty to soothe my anxiety about my air conditioning system and discovered a problem that if not taken care of immediately could have been a huge problem. I know a lot of business owners who own HVAC companies yet I still choose to go with Stay cool climate control. Keep up the great work!
