HVAC Installation Cost Calculator
Get an instant 2026 budget range based on national installed pricing, adjusted for your region — then let real local quotes confirm your exact number.
Estimates assume standard-efficiency equipment and existing ductwork in serviceable condition. High-SEER equipment, duct replacement, or zoning add to the range. Related: the full HVAC cost guide.
How this estimate works
The calculator multiplies your project size by 2026 national installed price ranges for the selected option, then applies a regional cost index. It intentionally returns a range, not a single number — real quotes vary with access, prep, code requirements, and current local demand. On mid-size projects the spread between the highest and lowest licensed quote routinely runs 20–40%, which is why comparing at least two quotes matters more than any calculator.
Frequently asked questions
What size HVAC system do I need?
Roughly 1 ton of cooling per 500–600 sq ft in hot climates, but a proper Manual J load calculation from a licensed contractor is the only accurate answer — oversized systems short-cycle and cost more to run.
Does this estimate include ductwork?
No. If ducts need replacement, add $2,500–$6,000 for a typical home. Ask every bidder to inspect ducts before quoting.
