  Thea is terrific.  We had an issue with our gas furnace/boiler.  The people we used to use came and said that the furnace needed to be replaced and that there was a safety issue.  Left us without heat for Christmas.  We called TC HVAC services and Thea came that day.  He fixed the problem which was a damper on flue and not the furnace.

Thea is prompt, extremely knowledgeable and reasonable.  TC HVAC is now our HVAC service team.

  They were very timely, finished the work in one visit, and my place looks great! The rates are excellent and I highly recommend them! I called them on a Friday night because my heater broke and they came first thing Saturday morning. They also gave me tips on how to keep the place warm until they got there, amazing work and people!

  I recently got a new HVAC system installed by TC HVAC.  The team was friendly and professional throughout the entire time so I had a great experience. They completed the work within the timeframe they gave.  I am very happy with the results and would recommend TC HVAC services for their excellent service.

  TC HVAC came out to diagnose my furnace and provided a second opinion. I have a 10 year old unit and the other guys, a well known HVAC company, wanted to charge nearly $5,000 for replacement parts and maintenance. TC explained what was necessary and what wasn’t, and I saved a lot of money.
