AC Installation
AC Installation for Centennial homes
A new AC in Centennial should be sized to your house at 5,722 feet, not copied from the old unit’s label. We run a load calculation, quote flat-rate, pull the City of Centennial Building Division permit and handle the paperwork.
We are a family shop, not a franchise call center. The tech who shows up can explain what failed and why, and the quote does not change after you say yes.
See our main ac installation page for how we approach this work across the metro.
AC Installation 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.
Sizing for Centennial
Design conditions here are a 87.3°F July average high at 5,722 feet. We size from a Manual J load calculation because an oversized unit short-cycles and leaves the house clammy, and an undersized one runs all afternoon.
Refrigerant change
New systems now ship with A2L refrigerants (R-454B or R-32). EPA’s May 2026 rule dropped the install deadline for leftover R-410A stock, so both are legal; we explain the trade-off on parts and service life before you choose.
Permit
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.

Rebates and programs for Centennial homeowners (2026)
Arapahoe County Weatherization Assistance: Free efficiency work for income-qualified households, including furnace and water heater safety testing and furnace replacement where eligible (303-636-1982). Source
CORE Cool Credits: CORE Electric members with central AC or a heat pump earn bill credits for letting an eligible smart thermostat take part in summer demand events. Source
Power Ahead Colorado: $1,500 off a new ENERGY STAR cold-climate heat pump (ducted or ductless) in an existing home. Needs pre-approval through a Power Ahead-badged contractor before work starts; stacks with utility and state incentives. Source
Colorado heat pump tax credit: $1,000 for air-source systems in 2026, claimed by a registered contractor who must pass at least a third to you as an invoice discount.
Our published range is $3,800 – $10,000 installed. Every Hytek job is quoted flat-rate and approved before work begins, so the price you agree to is the price you pay. Replacements get free in-home estimates; see the full HVAC cost guide for the other services.
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.
Should I get a heat pump instead of a new AC in Centennial?
Often, yes. A heat pump costs more than a straight AC but also heats, and in Centennial it can qualify for either Xcel’s heat pump rebate or CORE’s thermostat credits, depending on which utility serves the address and the $1,500 Power Ahead Colorado rebate (pre-approval required). A plain central AC has no current Xcel rebate. We quote both side by side.
Who provides gas and electricity in Centennial?
Electric: Xcel Energy for most homes; CORE Electric serves some addresses on the east edge. Gas: Xcel Energy. That matters because rebates, operating costs and who you call about a gas leak all depend on the utility.
