Enter your home details to estimate HVAC replacement costs.
How It Works
Our HVAC calculator estimates replacement costs based on your home's square footage, which determines the required system capacity in tons. We factor in system type, efficiency rating, and typical installation requirements.
Central AC with a furnace is the traditional choice for homes with existing ductwork. Heat pumps provide both heating and cooling with better efficiency, especially in moderate climates. Mini-splits are ideal for homes without ducts or for zone-specific climate control.
Higher efficiency systems cost more upfront but can save 20-40% on energy bills. Premium efficiency systems may qualify for utility rebates and federal tax credits, reducing the effective cost.
Frequently Asked Questions
How long does HVAC installation take?
A straightforward replacement typically takes 1 day. If ductwork modifications, electrical upgrades, or system type changes are needed, expect 2-3 days. Complete new installations with all new ductwork can take up to a week.
When should I replace my HVAC system?
Most systems last 15-20 years. Consider replacement if repairs exceed 50% of new system cost, energy bills are rising despite maintenance, the system uses R-22 refrigerant (being phased out), or heating/cooling is uneven throughout your home.
What SEER rating should I choose?
Minimum federal standard is 14-15 SEER depending on region. 16-18 SEER offers good efficiency for most climates. 20+ SEER makes sense in hot climates where AC runs frequently. Higher SEER pays off more in warmer regions with high electricity costs.
Heat pump vs. traditional AC: which is better?
Heat pumps are more efficient for heating in moderate climates (above 30°F average winter temp). They cost more upfront but save on operating costs. In very cold climates, a hybrid system with a gas furnace backup may be ideal. Heat pumps also qualify for significant federal tax credits.
Are there tax credits for HVAC systems?
Yes! The Inflation Reduction Act offers up to $2,000 in tax credits for qualifying heat pumps and $600 for efficient central AC systems. Many utilities also offer rebates. Check DSIRE (Database of State Incentives for Renewables & Efficiency) for local programs.
