We had Fuse Service install a new HVAC system for our home in June, replacing an old furnace and…read moreA/C unit that had run its course. This included removal of the old units and ductwork, new ducting throughout, a two-zone ducted heat pump system with two new air handlers, an outdoor heat pump, and a ceiling-mounted cassette unit for our primary suite (a room that gets a lot of direct sun and had always been tough to keep cool with the old system). Teodor, our project manager, did a great job assessing our home and specifying the system. The installation crew, Azamat and Val, did excellent, careful work removing the old system, running new ductwork, and installing all the new equipment. The install took about 7 days. Communication was great throughout; scheduling, installation, and permitting all went smoothly.

Fuse came in significantly lower priced than everyone for a superior system. We wanted to add an additional vent on the main floor, and some dampers for a few of the vents and everything went like butter. Lex and Maxat were the nicest people, arrived on time, left at 6pm each day leaving the house clean. It was a 3 day install and they finished on the third day. Beyond what they needed to do, Lex walked through things that would be checked by the inspectors even on work they didn't do (GFCI plugs close to where the old unit was), and walked me through why they did some of the things they did because I was curious. We're 3 days in so far, but the installation experience was great, and the daikin system is cooling the house great (and I can already see from the energy monitoring systems we have, it's so much more efficient!).

We would recommend Therma Tech to our friends and neighbors w/o hesitation.

I had an excellent experience with Henry from ThermaTech. My HVAC system stopped working properly…read moreafter another company had spent about two hours diagnosing it and quoted me more than $3,000 for a new control board, contactor, transformer, surge protector, and maintenance plan. Henry arrived, clearly explained each step of his diagnostic process, and quickly identified that the transformer and contactor were the actual issues. He completed the repair in about an hour and charged me $540 total, saving me roughly $2,500 compared with the previous quote. What impressed me most was Henry's honesty, expertise, and transparency. He did not try to upsell me or replace parts that were not needed. He took the time to explain what had failed, why the system was not powering on, and what he was doing to fix it. It is rare to find an HVAC company that combines strong technical knowledge with fair pricing and integrity. I would absolutely recommend ThermaTech to anyone looking for an honest and skilled HVAC professional.

Sal was very friendly and professional the whole time and his price was very competitive! He also gave me helpful tips to prolong the life of my unit. Fantastic work by Sal!

Dennis Sushko and Slava (Comfort Advisor) came to my house to walk the site, review the scope of work, and thoroughly address all of my concerns. Jessica in the permit department was fantastic with scheduling--she was incredibly proactive, kept me updated every step of the way, and even helped fill out the paperwork for local rebates. On installation day, Tony and Adam showed up right on time. Both were extremely professional. Because of tight space constraints on my wall, they had to work extra hours to complete the installation in a single day so I wouldn't be left without power overnight. They also did a spotless job cleaning up the workspace before leaving. I strongly recommend Freon Service to anyone looking for HVAC work or an electrical panel upgrade!
