Built for the houses we work in every day
Your central AC is done
Replacing an aging system? Quilt gives you cooling and heating from one system, with the highest efficiency ratings of any ductless heat pump on the market.
You have no ductwork
Older Westchester homes with radiators and window units don’t need a gut renovation to get real cooling. Quilt is ductless — there is no chase to build in every closet.
Some rooms never feel right
The bonus room that bakes, the bedroom that freezes. Quilt controls each room on its own, from the app or the Dial.
One system, four simple parts
A heat pump outside, slim units in the rooms that matter, and controls your family will actually use.
Industry-leading efficiency, independently certified.
Quilt’s efficiency ratings are certified by AHRI, the independent trade association that verifies every heating and cooling system sold. Its 2-zone SEER2 of 25 is at least 8.7% more efficient than the highest typical rating on the market, and its HSPF2 of 12 is at least 9% more efficient for heating.
