Professional and kind
Mark's Comfort Tech stood out amongst them all. We had four different HVAC companies come to our home to walk us through an installation process for full ductwork, furnace \& AC. Our home was built around 1964 and previously had baseboard heat and electric coil heating in the ceiling. What helped me choose to pick Marks Comfort Teck over other companies; 1. Rob Marks willingness to come back more than once to walk me through an installation process. 2. Rob always gave me the time needed to understand the installation and answer all my questions. Never made me feel rushed. Never made me feel as if he was rushed. The crew, Toby, Zac, and Joel, were professional and respectful to everyone in our family. They worked hard every day to make the installation strong and stable. We are very happy with the product and the installation from Marks Comfort Teck.

Excellent response and service. Would recommend to anyone!
Installers were absolutely great. They came in and got right to it. They answered any questions and gave a run down on the system when done. Installation was clean and professional. Very impressed.

No complaints, would highly recommend
We had a new furnace installed. Mark's price was reasonable and from the 3 estimates we received, they were the only ones who said they wouldn't cut through our finished ceiling. They were good to their word and our ceiling required no repairs.

Excellent customer service as we needed a new furnace in a hurry as it was in the winter and we had no heat for 3 days, and Mark and his employees did an outstanding job in getting us installed with a new furnace.
