They are awesome. Hottest day of the year and my air stops working and he was at my house within 30 minutes. 20 minutes later he had it fixed and I was blowing cold! I can't say enough how much I appreciated him! I'm from the Midwest and a little spoiled and not used to the heat. On top of that I thought his price was fair. He also gave me advice that next time that happens I need to shut it off. Thank you!
