Heat Pump & Mini-Split Tools
Use these free planning tools to estimate mini-split sizing, compare heat-pump options, understand cost factors, and troubleshoot common heat-pump questions. Results are intended for early planning and do not replace a contractor’s diagnosis, Manual J load calculation, or equipment-specific performance data.
Which Heat Pump Tool Should I Use?
| If you are trying to… | Start with this tool |
|---|---|
| Figure out what size mini-split a room may need | Mini-Split Sizing Calculator |
| Estimate a whole-home heat-pump size | Heat Pump Size Calculator |
| Build a preliminary installation or replacement budget | Heat Pump Cost Calculator |
| Understand why a heat pump is not heating, cooling, or operating normally | Heat Pump Troubleshooter |
| Compare heat-pump operating cost with gas, propane, oil, or electric heat | Heat Pump vs. Furnace Cost Calculator |
| Check current Iowa / Alliant Energy heat-pump incentives | Iowa Heat Pump Rebate Checker |
| Decide whether to compare a repair with replacement | Repair or Replace Calculator |
| Compare two or three HVAC proposals on the same scope | HVAC Quote Comparison Tool |
If you are not sure where to start, use the Troubleshooter for an existing system problem or the Heat Pump Size Calculator for a planned installation.
Mini-Split Sizing Calculator
Estimate a preliminary BTU range from room size, ceiling height, sun exposure, insulation, occupancy, room type, and climate.
Heat Pump Size Calculator
Estimate a preliminary whole-home BTU and tonnage range using conditioned floor area, climate, insulation, air leakage, windows, ceiling height, duct location, and whether the heat pump will be primary heat or part of a dual-fuel system.
Heat Pump Cost Calculator
Estimate a preliminary installation or replacement budget from system type, home size, ductwork, electrical work, equipment tier, cold-climate capability, and installation complexity.
Heat Pump Troubleshooter
Work through common symptoms such as no heat, no cooling, ice, AUX heat, emergency heat, short cycling, unusual noise, thermostat issues, breaker trips, and water leaks. The tool separates likely-normal behavior, low-risk homeowner checks, and situations that need professional service.
Heat Pump vs. Furnace Cost Calculator
Compare the operating cost of a heat pump with natural gas, propane, heating oil, or electric resistance heat using your own energy prices, furnace efficiency, HSPF2, and optional annual heating-only fuel use.
Iowa Heat Pump Rebate Checker
Check current Alliant Energy Iowa heat-pump Instant Discounts and see the current federal and Iowa tax-credit status for a planned installation.
Heat Pump Repair or Replace Calculator
Compare the factors that favor repairing an existing heat pump with the factors that make replacement worth pricing out, including system age, repair cost, recent failures, comfort, energy use, parts availability, and ownership horizon.
HVAC Quote Comparison Tool
Compare up to three heat-pump or HVAC proposals by total price, exact equipment, efficiency, low-temperature capacity, included scope, warranties, permits, removal, electrical work, ductwork, and rebates.
