System Size & Capacity
HVAC systems are sized in tons (cooling) or BTUs (heating). A proper Manual J load calculation is non-negotiable — affects cost by $500–$2,000 depending on what contractors find. Use our AC replacement calculator or heat pump calculator to see how tonnage affects your estimate.
Efficiency Rating (SEER2/AFUE)
Higher efficiency means higher upfront cost but lower utility bills. SEER2 18+ AC systems cost $1,500–$3,000 more than minimum-code units but cut cooling bills 30–40% annually. A 95%+ AFUE furnace pays back the premium in 4–7 years in cold climates. See our furnace calculator for side-by-side efficiency comparisons.
Labor & Regional Rates
HVAC labor ranges from $75/hr in rural Midwest markets to $150+/hr in coastal metros. Labor accounts for 40–50% of total installed cost. Getting 3 quotes is essential — the same unit can vary $1,500+ in installation cost between contractors in the same ZIP code.
Rebates & Tax Credits
The Inflation Reduction Act offers up to $2,000 federal tax credit for qualifying heat pumps and up to $600 for high-efficiency AC or furnaces in 2026. Many utilities stack $200–$600 on top. Check EnergyStar.gov before purchasing any system.
