Thank you Bryan & Thank you Don’s

Very Impressed

Ryan is an extremely professional and knowledgeable person. He installed vents in my laundry room, cut a pipe, and then vacuumed the room. He brought me covers for the vents which he bought himself because I didn’t have any. He is friendly and an incredible representative of Don’s Heating and Cooling.

“Thank you for your great review. Ryan is one our best technician and always goes out of his way to do the best job”

And yet  he always makes his extra effort seem so natural! He is a wonderful representative for your company.

Customer Service, Other, Quality, Timeliness

Just a note to thank Tyler for his service call yesterday. He was a very nice young man and very helpful and thorough with servicing my furnace and gave me very helpful advice.
You must be proud to have him on your team.
Thank You

We recently moved to the Alliston area and found ourselves having to look for a new wood stove which was a daunting task.
We had three quotes and decided to use Don’s Heating and Cooling whom I will highly recommend.
Don took the time to explain their services and came direct to the house to understand our requirements.
We liked the Napoleon brand he stocks as well.
Installation was scheduled quickly .
The installers Chris and Jamie I give kudos too, they worked many hours and went above and beyond the call of duty to ensure everything was perfect … the existing hole in the roof was larger then it should have been and Chris did some Fabrications to ensure it’s safety! I felt very comfortable in the dealings through the whole process.
Don came and did a home inspection after the fact which I feel is great customer service.
Thank you!!

It is with great pleasure that I share our experience with Don’s Heating and Cooling on December 14, 2017. Around 3 p.m., we noticed a gas smell in our furnace room. We called the gas company and they shut off our gas because a leak was confirmed. With the weather prediction of -17 over night, we were worried about getting someone out the same day. We called Don’s Heating and Cooling, where I spoke to Jasmine, who was very kind and efficient. She said she would have someone out to our home that night. The two gentlemen that came and fixed our gas leak were professional and friendly; they found the problem very quickly and fixed it. We are grateful for the efficient and professional service we were given. Thank you so much. We’ve used Don’s in the past, and will continue to only use Don’s Heating and Cooling in the future. Excellent Customer Service!
