Free heat-pump calculators and homeowner tools for sizing checks, cold-weather capacity, mini-split planning, installation cost, heating-fuel comparisons, heat-loss estimation, and contractor quote review.
These tools are designed for preliminary comparison and better contractor conversations. They do not replace ACCA load calculations, manufacturer equipment-selection data, electrical or permit review, or a qualified contractor’s site-specific design.
Heat Pump Size & Cold-Weather Capacity Calculator
Enter a Manual J heating load when available, or use a deliberately broad screening range, then compare it with manufacturer heating capacity at 17°F and 5°F.
Mini-Split Sizing Calculator
Estimate a broad BTU screening range and identify zone/layout questions before comparing single-zone and multi-zone proposals.
Heat Pump Cost Calculator
Build a transparent project budget from a 2026 national benchmark plus ducts, electrical work, backup heat, mounting, controls, permits, removal, incentives, and a contractor quote.
Heat Pump vs. Propane Cost Calculator
Use your electricity rate, propane price, furnace efficiency, and heat-pump COP to calculate delivered heating cost and break-even COP.
Heat Loss Calculator
Estimate whole-home design heat loss from an actual winter fuel/energy-use period rather than relying only on square footage.
Heat Pump Quote Checker
Check whether a contractor proposal documents sizing, equipment, cold-weather capacity, backup heat, ducts, electrical work, commissioning, warranties, and exclusions.
