furnace and AC install

Great technicians... Only issue is the return air vent they installed is noisier than expected... I would have made a different decsicion had I understood the noise impact.

Awesome installation, reasonable price. Only a fool wouldn't be pleased with Nicks abilities and knowledge.

I'm a retired Commercial Aircraft Technician, licensed on 5 Continents for aircraft inspection and release for international flights. I know ability when I see it, as well as dedication and satisfaction gained from doing a good job. Stay with it Nick, you'll make a lot of folks happy. A job well done.

Spring Tune Up and Duct Cleaning

Rick did a super job cleaning our ducts. Before and after pictures are amazing. Mitch did a terrific job on spring tune up. I consider Thirnton’s Team to be a trusted partner in our home maintenance.
