Frequently asked

Do heat pumps actually work in Boston winters?+

Yes — modern cold-climate heat pumps (like Mitsubishi Hyper-Heat and Bosch IDS) are rated to deliver full heat down to -13°F to -15°F, well below the coldest Boston nights.

Can I keep my furnace as backup?+

Absolutely. We often design 'dual-fuel' systems that use the heat pump as the primary source and keep your existing furnace as backup for extreme cold — a great option for larger homes.

How long does an install take?+

Most whole-home heat pump installs are completed in 2–4 days by our own W-2 crews, with minimal disruption to your home.
