I have been using Cool Temp Air for a year and a half now, since I've owned my current home. The last time I used them, we were doing an addition to the home, so I reached out to them to check on our unit. They were flexible with their scheduling, and the gentleman that came out was prompt, professional, and polite. He checked our unit to make sure it was working properly, and made some adjustments to make sure it would continue to work well with the new addition. I plan on using them in the future.
