AC installation cost by system.
Installed pricing for Belgrade, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
Belgrade, Montana homeowners considering AC installation face a range of costs shaped by local factors. Typical installed prices for a like-for-like central AC system run from $3,600 to $7,200, while a new central AC with ductwork can cost $5,400 to $11,700. Ductless mini-splits range from $2,700 to $7,200, and heat pumps from $4,500 to $10,800. Because Belgrade is a smaller market (tier 4) with a median home age of 29 years, many homes may need duct modifications or upgrades to meet current codes. Montana requires a mechanical permit for AC installation, and cold-climate sizing is critical. Most homes use gas heating, so a recommended system is an AC-gas furnace combination. Federal 25C tax credits are available: up to $600 for high-efficiency central AC and up to $2,000 for a qualifying heat pump.

Recommended unit for Belgrade
Given Montana’s cold climate and gas heating, high-seer2 ac + gas furnace is the sensible default for most Belgrade homes. The cooling season is short, so the budget is better spent on heating efficiency than on ultra-high SEER2. A pro can confirm the right size and system for your home with a load calculation.
