Heat Pump Repair vs. Replacement Calculator

Should you repair your existing heat pump or invest in a new system? Compare upfront costs, energy savings, future repairs, and long-term ownership expenses.

Before You Begin

Use contractor estimates and your actual utility bills wherever possible. This tool compares projected costs and provides decision guidance; it does not diagnose equipment condition or guarantee future savings.

1. Existing Heat Pump Information

Current System Age (Years) Estimated Remaining Life After Repair (Years) Current System Condition Current Repair Estimate ($)

The remaining-life estimate is an assumption, not a prediction. Ask your technician whether parts availability, compressor condition, corrosion, or refrigerant issues could shorten the system's useful life.

2. Replacement Heat Pump Costs

New Heat Pump Equipment Cost ($) Replacement Installation Cost ($) Additional Replacement Costs ($) Applicable Rebates & Incentives ($)

Include ductwork modifications, electrical upgrades, permits, controls, and other required work. Enter only incentives you expect to qualify for and receive.

3. Energy Consumption & Operating Costs

Current Heat Pump Electricity Use (kWh/year) New Heat Pump Estimated Use (kWh/year) Electricity Price ($/kWh) Annual Electricity Price Change (%)

Include heating, cooling, and auxiliary electric heating in both annual consumption estimates. Compare the same home, comfort settings, and typical weather conditions. Efficiency ratings alone cannot reliably determine annual kWh savings.

4. Maintenance & Future Repairs

Existing System Annual Maintenance ($) New System Annual Maintenance ($) Expected Additional Repairs on Old System ($/year) Expected Additional Repairs on New System ($/year)

Future repair allowances are expected annual averages, not guaranteed bills. Do not include today's quoted repair in the annual allowance. Consider warranty coverage and service history when estimating future repairs.

5. Analysis Settings

Comparison Period (Years) Expected Life of New Heat Pump (Years) Future Replacement Cost Inflation (%/year) Annual Discount Rate (%)

Model assumption: If the repaired system reaches its estimated remaining life during the analysis period, the repair pathway includes a future replacement. The model uses the entered new-system cost, inflated to that future year, without assuming a future rebate. Both pathways are compared over the same period.

Recommended Next Steps

Safety First

Do not continue operating equipment with confirmed electrical hazards, damaged wiring, overheating, or other unsafe conditions. A qualified HVAC professional should determine whether repair is safe and practical. Financial calculations cannot override safety requirements.

How to Use the Heat Pump Repair vs. Replacement Calculator

Enter your heat pump's age, the quoted repair cost, and its estimated remaining service life. Next, provide the installed cost of a replacement system, available incentives, annual electricity consumption for both systems, and expected maintenance and repair expenses. Choose a comparison period to see how the two decisions may affect your long-term costs.

When Does Heat Pump Replacement Make Sense?

Replacement may become more attractive when repair costs are substantial, reliability is deteriorating, replacement parts are difficult to obtain, or a new system offers meaningful energy savings. However, a properly functioning heat pump with a manageable repair and several years of expected service life may still be economical to keep. The best decision depends on verified equipment condition, comparable installation quotes, and realistic operating-cost assumptions.
