Learn moreWhy These Brands
Cold-Climate Performance
Southern NH winters are serious. We only install heat pump brands rated and proven for cold-climate operation. Mitsubishi, Daikin, LG, and Bosch cold-climate systems all maintain strong performance well below freezing.
Parts Availability
A brand is only as good as the support behind it. We stock common parts for the brands we install and can source others quickly through our distributor network. That matters when your system needs repair on a cold night.
Extended Warranties
Top-tier dealer status with Mitsubishi, Daikin, LG, Bosch, Amana, American Standard, and Goodman means we can register extended manufacturer warranties that aren't available through standard dealers. 12 years parts/compressor on Mitsubishi mini splits is one example. For every other brand, your warranty is registered correctly at installation.
Proven in Our Service Area
Family-owned and serving Southern NH since 1928. The brands on this page are ones we've serviced for years and know hold up well in NH homes and weather conditions.
