What our customers are saying
The Guys Were Great
"The guys who came to my house to do the repair were great. They were able to diagnose an issue and worked with Carrier to get it covered under warranty. I have had lots of issues with my furnace, I wish I would have started with them!"
- Fisherman
Very Happy
"I wanted to be sure to leave a review because I’m very happy with the work and equipment I received by CMS. I had Dominic come out to look at my furnace, which wasn’t working. We tried a few parts to try to keep my furnace working but it was over 20+ years old and needed to get replaced. Aj came over and gave me and my wife a fair quote and we scheduled install of our new Carrier furnace. Dario was the tech who came to install our furnace. I needed him to come a little early because I was recently in a car accident and needed to go to my doctor. He came early was very respectful and installed my equipment in no time. He cleaned up the area where the old furnace was and the new furnace was installed wonderfully and is currently warming my home in the cold weather we have been having . The front end was very responsive and helpful at getting my furnace checked out and they didn’t give me the run around as I’ve had with other companies . Nikki and Janis were amazing and worked with my busy schedule . They were one of the best company’s I’ve ever worked with and wanted to leave this review In hopes that helps you if your looking to have someone to come out and resolve your heating or cooling issue . Happy holidays"
