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.
