Testimonials
They converted my furnace and water heater from propane to natural gas. They were professional and it was a pleasure to have been a customer. Job was done well. Thank you!
Very thorough. Great service. Definitely will use again.
Dave was willing to work with me in designing my heating system. A lot of heating companies did not want to work outside the box and install my new Caddy wood furnace. Dave was not afraid to learn about this new system and help me correctly install it. He went beyond the call of duty. I would definitely recommend him.
Quick and reliable service!
Dave did an AWESOME job with our furnace and hot water heater! We couldn't be more pleased and would highly recommend Mack's Heating and Air Conditioning.
BIG SHOUTOUT AND THANKS TO DAVID and Mack's Heating for saving us yesterday when the oil tank suddenly needed to be replaced. You rock Dave!
