AC vs Heat Pump: What You’ll Pay Each Year (Not Just What It Costs to Buy)

This calculator compares the estimated annual operating cost of keeping a standard AC versus switching to a heat pump (or a hybrid setup). It uses your annual heating/cooling energy needs, your electricity price, local winter severity, and the upfront cost difference to show which option is likely cheaper over time.

From Your Loads to Annual Cost: Convert Heat Pump Electricity vs AC + Heat

Cooling cost is estimated from your annual cooling load and an assumed AC efficiency, multiplied by your electricity rate. Heating cost for a heat pump is estimated by converting your annual heating load into expected electric usage using an efficiency adjusted for climate severity. For a hybrid option, the tool splits heating between the heat pump and backup heat, adding a colder-climate penalty for the portion that relies on backup.

Why Climate Tier and Unit Choices Matter More Than You Think

Heat pumps generally do best in mild to moderate winters; in colder zones, efficiency drops and backup heating covers a larger share. Because this tool uses simplified average efficiency assumptions, the accuracy is best for planning-level comparisons rather than exact bids. If your “heating load” comes from BTU vs kWh (thermal), be sure your input matches the calculator’s intended basis so the conversion to electric heating cost stays consistent.

Don’t Miss These Common Oversights

The comparison typically excludes maintenance, ductwork changes, and most incentives/credits (unless you account for them separately), so real-world totals may differ. If electricity is unusually expensive during winter months, the annual estimate could be optimistic because it assumes a constant rate. If your heating load is zero, the heating portion of the analysis becomes irrelevant—your decision will largely depend on cooling cost and the upfront difference.
