Rebate standards

A model meets a standard when at least one of its certified pairings does. Programs can have other rules too.

These are certified test ratings, not a recommendation for your home. The right size comes from a load calculation by a contractor.

Side by side with another model

Only models of the same size class (ductless, 2 tons) can be compared, so their numbers mean the same thing.

What size is my system?

Tons and Btu

A heat pump’s size is its rated cooling output, in Btu per hour. Installers talk in tons: one ton is 12,000 Btu per hour, so a 3-ton unit is about 36,000.

Where to find yours: the nameplate sticker on the outdoor unit lists the model number. Many model numbers include the size in thousands of Btu, such as 24 (2 tons), 36 (3 tons) or 48 (4 tons). Your quote or AHRI certificate also lists it. Look up a model number
