I would like to thank Don's Heating and Cooling in Alliston for the great service I received in August 2018' My central air system died on me. It was about 20 yrs old. I called Don's and they sent someone out to check it for me. Because of it's age, I asked to have a new one installed. A new one was here in 3 days and hooked up. The men that were here were very polite, didn't leave a mess and I'm thrilled with the new unit. Thank you very much guys. You are at the top of my list.
