Decker Heating & Air ConditioningDecker Heating & Air ConditioningInstalled central AC in Menomonee Falls generally runs $4,500 to $8,500, most homes near $5,500 to $7,000, set by tonnage and SEER2. Full Comfort Heating & Air handles the removal, sizing, and hookup so you don't lift a thing across Falls Village, Rocky Point, and Grandview Highlands.

Installed central AC price ranges by size and efficiency (Menomonee Falls, ballpark)
The two largest cost factors on a central AC install are system size (tonnage) and efficiency (SEER2). Menomonee Falls homes commonly need 2 to 4 tons based on square footage, insulation, and layout. A 14.3 SEER2 unit meets the current federal minimum for the northern region and is the value pick. Stepping up to 16–18 SEER2 or a variable-speed system raises the price but lowers summer bills during long heat stretches.
Reusing sound ductwork and an existing indoor coil keeps a central AC replacement in the lower range. Replacing the evaporator coil, a corroded lineset, or the electrical disconnect adds several hundred dollars each. Homes switching from an aging or undersized system may need duct sealing. A load calculation on-site prevents oversizing, which short-cycles the unit and wastes energy.
Central AC units over 12 to 15 years old using discontinued R-22 refrigerant are usually cheaper to replace than repair, since R-22 costs have climbed sharply. A newer unit with a failed capacitor or fan motor is worth repairing. A single major failure on an aging system rarely justifies the cost when a full replacement carries a manufacturer warranty and cuts operating expense.
When an AC fails during a Menomonee Falls heat wave, same-day assessment and, where stock allows, same-day install keeps a household cool without a multi-day wait. Flat upfront pricing is provided before any work begins, so the number quoted is the number paid. The $150 minimum service charge applies to diagnostic visits and is credited toward the job when you proceed.
Menomonee Falls sits in Waukesha County, where summer highs push into the upper 80s and 90s with heavy humidity, so central AC sizing must handle real cooling load, not just square footage. Older homes in Silver Spring Highlands and Woodland Estates often have tighter mechanical rooms and legacy ductwork that affect coil placement and price. Electrical permits through the Village of Menomonee Falls are typically required for a full condenser and disconnect replacement, and that permit cost is folded into the quoted price. Newer builds in Cardinal Crest and Nor-X-Way Estates usually have modern ductwork ready for a straight swap, keeping installs in the lower range. We serve Rocky Point, Grandview Highlands, Country Estates, and nearby Lannon.
Most Menomonee Falls homes need 2 to 4 tons, roughly one ton per 500–600 sq ft, but a proper load calculation accounting for insulation and windows sets the exact size.
A standard central AC replacement reusing existing ductwork typically takes 4 to 8 hours in one day; adding ductwork or coil work extends it.
A 16–18 SEER2 unit costs more upfront but lowers bills across long humid summers; payback depends on runtime and current energy rates.
Units over 12–15 years old on R-22 refrigerant usually favor replacement; newer units with a minor part failure are worth repairing.
A full condenser and electrical disconnect replacement typically requires a Village of Menomonee Falls permit, which is included in the installed price.
