Mini-split payback calculator

Compare an existing heating or cooling setup with a mini-split project cost and efficiency assumption to estimate savings and simple payback.

Payback assumptions

This is a planning estimate, not a financial forecast. Actual savings depend on weather, fuel prices, utility rates, thermostat settings, building load, installation quality, backup heat, maintenance, and how much of the old system the mini split displaces.

Existing systemThe system the mini split would offset.Climate zoneUsed only when defaults are selected.Annual cost sourceUse your actual cost or the climate default.Mini-split system costEquipment cost before installation.Install estimateUse the installation-cost estimator if you need a range.Efficiency sourceUse published model ratings or enter SEER2/HSPF2 manually.SystemUses the selected model's SEER2 and HSPF2.

Selected model has a current minimum imported price of $1,050.
