AC Repair

What’s different about Onalaska.
Generic cost pages skip the things that actually decide your price and which system fits here — local code, climate, and the money you can claim back.
Recommended unit for Onalaska
Given Wisconsin’s cold climate and gas heating, high-seer2 ac + gas furnace is the sensible default for most Onalaska 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.

What Onalaska code requires
Installing or replacing an HVAC system in Onalaska follows Wisconsin rules under the state mechanical code. Here’s what applies statewide:
- PermitRequired
Mechanical permit pulled by your licensed HVAC contractor; covers equipment, refrigerant, and the electrical disconnect.
- SEER2 minimum13.4 SEER2 (North)
Federal North-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.
- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
Cold-climate state: equipment must be sized for severe winter design temps; mechanical permit and a licensed Wisconsin HVAC contractor (DSPS) required even for like-for-like changeouts.
