What This Calculator Does
The HVAC Cost Calculator estimates the cost of installing a new heating, ventilation, and air conditioning system based on your home size, system type, and 2026 US national average pricing. Enter your home size in square feet and select the system type to get a cost range.
HVAC replacement is one of the most significant home maintenance investments. A typical system lasts 15-20 years, and efficiency standards continue to rise - 2026 SEER2 minimums are significantly higher than systems installed just a decade ago.
How to Use
- Enter your home's heated/cooled square footage.
- Select the system type - central AC + furnace (most common), heat pump, or ductless mini-split.
- Select efficiency tier - standard (SEER2 15-16) or high-efficiency (SEER2 18+).
- Click "Calculate" to see the total installed cost estimate.
- Add $500-$2,000 for ductwork modifications if replacing a different type of system.
