Thornton, CO — local facts

Ductless Mini-Split Installation in Thornton: what’s different here

In Thornton the electric provider can change from one street to the next (Xcel or United Power), and that decides which heat pump rebate a homeowner can use.

Where they fit in Thornton

Most Thornton homes were built from the 1990s on, with older 1950s–70s stock in south Thornton. The usual mini-split jobs here are finished basements, bonus rooms and rooms at the end of long duct runs that never get comfortable.

Rebates

A cold-climate ductless heat pump in Thornton can qualify for either Xcel’s or United Power’s heat pump rebate, depending on which utility serves the address; the $1,500 Power Ahead Colorado rebate (pre-approval required); Colorado’s $1,000 air-source heat pump credit, at least a third of which the installer must pass to you as a line-item discount.

Winter operation

Rated cold-climate units keep heating well below 19°F, Thornton’s average January low. We mount outdoor heads on brackets or stands above the snow line.
