Heat Pump Installation in Castle Rock: what’s different here
Castle Rock sits near the Palmer Divide and averages 57.5 inches of snow a year. Unlike most of metro Denver, homes here usually get gas from Black Hills Energy and electricity from CORE, not Xcel.
Your rebates
Castle Rock homes can stack no Xcel electric rebate, because CORE Electric offers thermostat credits rather than a heat pump rebate; 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.
Cold performance
Cold-climate models hold most of their capacity down to 5°F. With a 3°F winter design temperature in Castle Rock, we size to the heating load and usually keep the existing gas furnace as backup (dual fuel) for the coldest hours.
Electric service
CORE Electric Cooperative. Heat pump operating cost depends on that rate, so we run the numbers on your actual utility before you commit.
