HVAC Maintenance & Tune-Ups in Centennial: what’s different here
With a median home built in 1983, many Centennial houses still run on original ductwork while the furnace and AC are on their second or third replacement.
Fall visit
Before the first freeze we test combustion and CO, check the heat exchanger, clean the flame sensor and verify the igniter.
Spring visit
Before cooling season we clean the condenser coil (cottonwood fluff and dust are the big clog here), test capacitors and check refrigerant against altitude-corrected targets for 5,722 feet.
Why it pays here
With a median home built in 1983, many Centennial houses still run on original ductwork while the furnace and AC are on their second or third replacement.

Do I need a permit for HVAC work in Centennial?
Repairs generally do not. Replacing or installing a furnace, AC, heat pump or water heater does. Permits for Centennial addresses go through City of Centennial Building Division. Like-for-like AC, furnace and water heater swaps are One-Stop Permits through the city’s online portal, and the installer must hold a City of Centennial contractor license. We pull the permit and schedule the inspection.
What HVAC rebates are available in Centennial in 2026?
For heat pumps: either Xcel’s heat pump rebate or CORE’s thermostat credits, 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. Xcel’s gas furnace rebates ended Jan. 1, 2026, and the federal 25C credit does not apply to 2026 installs.
When should I book a tune-up in Centennial?
Furnace: September or early October, before the first cold night. AC: April or May, before the first 85°F day. Service plan members get priority scheduling during the rushes.
Who provides gas and electricity in Centennial?
