Operating cost estimate
Estimate energy cost from equipment capacity, efficiency, usage, and utility rates.
Use rated cooling or heating output, as applicable.
Rough estimate only; not a load calculation.
SEER2 rating for cooling.
0–24 hours. Actual cycling and weather affect usage.
Default reference: US residential average for 2025; edit for your utility rate.

Estimate based on the entered assumptions.
Energy estimates are simplified planning figures, not a guaranteed utility bill. SEER2 and HSPF2 are seasonal ratings; this calculator uses an equivalent full-load runtime approximation. Gas cost excludes furnace blower electricity.
How to use the calculator
Choose Installation Cost to estimate equipment installation, or Operating Cost to estimate energy use. Select a capacity input method, enter efficiency and utility rates, and the estimate updates automatically.
Assumptions and limitations
Installation ranges are broad national US planning estimates and may not match local quotes. Extras are allowances and are only added when selected. Area-based capacity is a rough rule of thumb; a professional load calculation is more reliable.
