Brenda I had 3 young men that came to my house this morning and removed my old furnace and AC and replaced it with new ones. It only took them 5 hours and they were done. Very pleasant and informative, and they worked well together.

Cole came out to service my mom’s very dated furnace and was phenomenal at explaining what needed to be replaced as well as the how and why of the new equipment. What was most important was that he listened to her and put her at ease. She would give him 10 stars if she could!

I signed up for the maintenance plan with Stay Cool Climate Control. Travis arrived early and explained each step of the process as he performed the inspection/maintenance. He gave me some helpful tips to keep my unit running efficiently. I also appreciate the peace of mind knowing that Stay Cool Climate Control will be there for me if anything breaks down in the future.

I would recommend this company hands down, from Carter to the techs, they treat you like family. Give them a call, you won't be disappointed.
