Efficiency and capacity vary by matched indoor/outdoor system and size. Final equipment and an installed-cost range require a property assessment.
We do not sell every heat pump on the market. Each model in our lineup has been vetted against four criteria specific to New England homeowners.
Every cold-climate model we carry has been tested and rated for sub-zero operation. We prioritize models that maintain at least 60% capacity at 5°F.
Minimum 10-year compressor warranty on every model. We track failure rates and remove products that do not meet our standards over time.
Our technicians are factory-trained on every brand we offer. Deep installer familiarity means faster installs, fewer callbacks, and better long-term performance.
We include standard, premium, and cold-climate options at different price points so every homeowner can find equipment that fits their budget and needs.
