The heating professional that came on our call when our furnace went out was very professional, courteous, and determined to find the cause of our furnace problems. He worked non-stop on a difficult furnace diagnosis and ended up here after 5 p.m. quitting time on a Friday, but he got it working again! You can be assured that Mark's Heating and Cooling will be our number one place to call for all our heating and cooling issues in the future. They did a phenomenal job!

We used Marks for our basement finish along with service work and have been very impressed with Mark and his staff. They’ve always been very affordable compared to others.

I hired them to install a new furnace 4 years ago and I haven't had a single problem. I bought a new shop condo that needs a furnace so I had to look them up to get another furnace installed and figured I should leave a review about how great they were on my first install!
