Why Is My Electric Bill So High With a Heat Pump?

If your electric bill is higher than expected with a heat pump, you’re not alone—and it usually comes down to a few key issues that can be fixed.

Common Reasons Your Heat Pump Is Costing More

1. Dirty Filters or CoilsWhen filters or coils are clogged, your system has to work much harder to move air and heat your home—driving up energy use.

2. Low Refrigerant or Poor Charge If the refrigerant isn’t at the correct level, efficiency drops fast. The unit will run longer and pull more power just to keep up.

3. Incorrect Settings or Controls Running in emergency heat, improper temperature settings, or bad thermostat programming can skyrocket your bill without you realizing it.

4. Lack of Regular MaintenanceHeat pumps need yearly servicing—especially in Nova Scotia’s climate. Without it, performance slowly declines and energy use climbs.

5. Improper Installation or Sizing If the system wasn’t sized or installed correctly, it may short cycle or run constantly—both of which waste electricity.

6. Defrost or Sensor Issues Faulty sensors or defrost cycles can cause the unit to run inefficiently or even heat when it shouldn’t.

The Reality

A properly running heat pump should save you money, not cost you more. If your bill is high, your system is almost always underperforming.
