Very Happy with the Whole Process!!

“Don came over to look at my 20 year old furnace and we both decided that it was a good time to have it replaced as winter was approaching. We went with a Carrier which we previously had and has served us well over the years. Don was able to get me a very generous discount from Carrier as the part that the old furnace needed was heavily backordered. A few days later Ashley came with his partner and had it installed in about 4 hours and they were very professional and very nice people. Very happy with the whole process!!”

We Are Doing Our Best to Support Local Businesses

“We purchased a barbeque and they delivered it assembled and in pristine condition right to our door as promised. They provided competitive pricing and we have heard from others in the area their service is highly recommended should we ever need it. We are doing our best to support local businesses and they make it easy to choose them as our preferred store and dealer!”

Really like Don's Heating & Cooling and have had Chris tune up our furnace for winter more than once over the years! Always an excellent experience with COVID protocols in place this year.
