Heat pump experts — for duplexes, triple deckers and more
From Boston to Worcester, multi‑family homes are staying comfortable year-round with heat pumps. They don’t just heat — they cool too, making them ideal for properties with diverse tenant needs.

Why heat pumps make sense for multi‑family properties
Heat pumps are the most modern and energy-efficient way to heat and cool multi-family properties. (Yes, they heat AND cool!) The three biggest benefits?
Efficient heating + cooling in one system: Heat pumps can serve individual units or entire buildings. Whether your property has existing ductwork or not, there are flexible options (ducted or ductless) to match your building’s layout.
Cost-effective: You can get up to $10,000 per unit in Mass Save™ rebates, plus long-term energy savings. If you’re switching from oil or electric baseboard, utility bills can drop by as much as 50%.
Environmentally friendly: Heat pumps are better for the planet and improve indoor air quality. No fossil fuel combustion means cleaner air inside and reduced emissions outside.
