AC Installation
AC Installation for Westminster homes
A new AC in Westminster should be sized to your house at 5,325 feet, not copied from the old unit’s label. We run a load calculation, quote flat-rate, pull the City of Westminster 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 Westminster: what’s different here
Westminster’s 1970s–80s housing peak means many homes are on original or second-generation furnaces and AC.
Sizing for Westminster
Design conditions here are a 91.1°F July average high at 5,325 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
Furnaces, ACs, heat pumps, water heaters and evaporative coolers all need a permit, filed paperless through eTRAKiT by a city-registered contractor.

How much does ac installation cost in Westminster?
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 Westminster?
Repairs generally do not. Replacing or installing a furnace, AC, heat pump or water heater does. Permits for Westminster addresses go through City of Westminster Building Division. Furnaces, ACs, heat pumps, water heaters and evaporative coolers all need a permit, filed paperless through eTRAKiT by a city-registered contractor. We pull the permit and schedule the inspection.
What HVAC rebates are available in Westminster in 2026?
For heat pumps: 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. Westminster offers a free Home Energy Squad Plus visit (code WESTY2026) and a city-partnered Switch Together heat pump group buy with registration open until Nov. 18, 2026. 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 Westminster?
Often, yes. A heat pump costs more than a straight AC but also heats, and in Westminster it can qualify for either Xcel’s or United Power’s heat pump rebate, 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 Westminster?
Electric: Xcel Energy for most homes; United Power on some edges. Gas: Xcel Energy. That matters because rebates, operating costs and who you call about a gas leak all depend on the utility.
