2. Tax Credits & Incentives in Wisconsin
Federal: $2,000 for heat pumps, up to $600 for efficient furnaces. The federal Inflation Reduction Act (IRA) provides credits through 2032. Heat pump systems qualify for the highest credit ($2,000) — making them worth serious consideration for Wisconsin homeowners.
3. Top Tip for Wisconsin HVAC Buyers
In Wisconsin, 90%+ AFUE gas furnaces significantly reduce heating costs vs standard 80% AFUE units — payback in 5–8 years for most homeowners. Consider a dual-fuel heat pump (heat pump + gas backup) for the best combination of efficiency and cold-weather reliability.

Use the "$5,000 Rule": multiply the unit's age (years) by the repair cost. If the result exceeds $5,000, replacement typically makes more sense financially. Example: a 12-year-old unit needing a $500 repair = 12 × $500 = $6,000 — lean toward replacement. Also replace when: (1) AC is 15+ years old or furnace is 20+ years; (2) repair cost exceeds 50% of replacement cost; (3) R-22 refrigerant is involved (discontinued, now $150+/lb to recharge); (4) energy bills have risen 20%+ without explanation. In Wisconsin, getting a replacement quote alongside a repair quote is always worthwhile — contractors in the state average 9,800 for full replacement.
