Heating & Cooling Cost Calculator | Heat Pump vs Gas Furnace + SEER Savings
⚡ HVAC Cost & Efficiency Explorer
Compare heat pump vs. gas furnace running costs | Estimate SEER upgrade savings
Choosing between a heat pump and a gas furnace — or deciding whether to upgrade to a higher SEER air conditioner — can be confusing. Our interactive HVAC cost calculator puts real numbers in your hands. Adjust the sliders and see instantly how your energy bills change.
How the HVAC Cost Comparison Works
- Heat Pump vs. Gas Furnace: We calculate annual operating costs based on your home’s size, climate zone, electricity & gas rates, and equipment efficiency (HSPF and AFUE).
- SEER Upgrade Savings: Compare your current AC’s SEER rating with a new high-efficiency unit to see potential energy savings and payback.

Frequently Asked Questions (FAQ)
1. What’s the difference between SEER and HSPF?
SEER measures cooling efficiency (air conditioners & heat pumps). HSPF measures heating efficiency for heat pumps. Higher numbers = lower running costs.
2. Is a heat pump always cheaper than a gas furnace?
Not always. It depends on local electricity vs. gas prices and climate. In mild or mixed climates, heat pumps often save money. In very cold regions with cheap gas, a gas furnace may be more economical. Our calculator factors both.
3. How accurate is this HVAC cost estimator?
We use industry-standard formulas and real US climate data. For a precise Manual J or energy audit, always consult a licensed HVAC contractor.
4. What SEER rating should I buy?
Federal minimum is 14-15 SEER2 depending on region. For the best long-term savings, SEER 18-20 often provides the optimal balance of upfront cost vs. energy reduction.
5. Can I use this calculator for a mini-split or ductless system?
Absolutely. The same efficiency metrics apply. For heat pump mini-splits, input the appropriate HSPF/SEER values.
