8130 Howe Industrial Pkwy Suite A, Canal Winchester“Chris was very professional and took the time to explain everything to me. He made some suggestions to improve the safety of my home and was not pushy trying to sell any unnecessary services. I was comfortable listening to him and confident in his professional opinion. I would recommend Mack Heating and Cooling to others.“
“Very professional staff and technicians. HVAC work completed on time and as quoted. Competitive pricing with no hidden charges. Highly recommend CHC Services for any HVAC services needed.“

10 E Waterloo St, Canal Winchester“Almost all of my home's major systems are original, so they are/were around 23 years old. I was told by another HVAC company that my furnace had cracks in the housing of the furnace. I got pricing from 3 different HVAC companies; Keystone offered me the best price AND even replaced my original hot water tank for a great price. On top of this, they let me put it on my credit card without an added charge. The technicians were all very nice and didn't leave behind a mess in my home. They've come out recently to check to make sure that the AC unit is working as it should be because it couldn't be checked in the cold temps of January. My only criticisms are that they were a bit late on the day of the install due to delays obtaining the unit at the warehouse. And the office help is hard to get a hold of. All in all, though i am very happy with my experience with Keystone.“

“Thank you for your quick and prompt attention on getting my Carrier unit replaced. The installation went smooth and it even looks better than the first installation back in 2020. Communication on some of our issues could have been handled better, but overall service is great!“
