Heat pump installers and rebates in Denver, CO

Denver is a gas-heated city at altitude: of the 335,428 occupied housing units, 61% heat with natural gas, 36% with electricity, and oil and propane together under 2% (Census ACS 2020-2024, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US0820000, checked 2026-10-21). The 359,581 total units split between 40% single-family detached, 9% single-family attached, 5% two- to four-unit buildings and 45% in buildings of five or more (Census ACS 2020-2024, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US0820000, checked 2026-10-21), and the stock runs older than the Sun Belt doors: 17% of units date from before 1940, 55% from before 1980 and 31% from 2000 or later (Census ACS 2020-2024, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US0820000, checked 2026-10-21). Denver sits at 5,280 feet, where the thin air reduces both the heating capacity and the cooling capacity of every outdoor unit by roughly 5% compared to the sea-level rating, so the installer uses altitude-derated performance tables rather than the nameplate BTU when selecting the system. The gas furnace in a mid-century Denver bungalow is the most common replacement target on this door, and the question is whether the homeowner wants a full swap or a dual-fuel setup that keeps the furnace as backup below the balance point, because a cold-climate heat pump at altitude still covers most Denver winter nights but the handful of sub-zero nights each year push the economics toward keeping the gas line.
