What changes the price
System size and SEER2 rating
Upgrading from a 14 SEER2 baseline to a 17 SEER2 variable-speed system typically adds 1500 to 3000 dollars but cuts cooling bills 20 to 30 percent.
Ductwork condition
Crews charge separately if existing ducts leak more than 15 percent or are undersized for the new equipment. Aeroseal-style sealing runs 1500 to 3000 dollars.
Climate zone
Cold-climate heat pumps cost more but qualify for federal IRA rebates and state utility programs that knock 2000 to 8000 dollars off the sticker price.

Frequently asked questions
How long does an HVAC replacement take?+
A standard split-system swap takes one full day. Heat pump conversions, ductwork add-ons, or panel upgrades extend the job to two or three days.
What size HVAC do I need?+
Plan for 20 to 25 BTU per square foot of conditioned space in most US climates. A 2000 sq ft home typically needs a 3 to 4 ton system. Get a Manual J load calculation before sizing.
Are there tax credits for HVAC replacement?+
The federal 25C credit covers up to 2000 dollars for qualifying heat pumps and 600 dollars for high-efficiency AC and furnaces through 2032. Many states stack additional rebates.
Is it cheaper to repair or replace HVAC?+
Replace if the unit is over 12 years old, the repair quote exceeds half the replacement cost, or the refrigerant is R-22 (no longer manufactured).
Can I finance an HVAC replacement?+
Most contractors offer 0 percent for 12 to 18 months through Synchrony or GreenSky. Manufacturer rebates often require financing through approved lenders.
