AC installation cost by system.
Installed pricing for Farmington, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Farmington, Utah, AC installation costs typically range from $3,700 to $7,500 for a like-for-like central AC replacement, and $5,600 to $12,200+ if new ductwork is needed. Ductless mini-splits run $2,800–$7,500, while heat pumps cost $4,700–$11,200+. Given the cold-dry high-desert climate, many homeowners pair a central AC with a gas furnace for efficient heating.

With a median home age of 24 years, older ductwork or undersized systems are common considerations.

- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
Cold-dry high-desert climate: equipment should be sized for hard winter heating loads, and a cold-climate (NEEP-listed) heat pump is required to earn the top Rocky Mountain Power Wattsmart rebate.

AC Installation in Farmington, explained.
What affects AC installation cost in Farmington?
Labor rates reflect the local market, and permit fees add to the total. System choice matters: a heat pump may qualify for the federal 25C tax credit (up to $2,000) and a Rocky Mountain Power Wattsmart rebate if it's a cold-climate model. Adding or replacing ductwork significantly raises costs. Home size and existing duct condition also influence pricing. High-efficiency units cost more upfront but can lower long-term energy bills.
