Why is my electric bill so high?


Many things can cause high electric bills. These could range from a mistake by the electric company, old, inefficient appliances like water heaters, freezers, refrigerators or just poorly insulated houses all wasting energy.

Ruling these things out, that leaves one main culprit... the heating system, especially if it is a heat pump. Of course the electric bill will be higher during the coldest months because that's when the supplementary heat is on the most. But after taking these things into consideration, if the electric bill is higher than normal, it is very possible that there could be a problem with the heat pump.

These problems can range from minor things like a dirty filter to a major item like a damaged compressor. Some of them are listed below. Items in blue can be addressed or fixed by the homeowner. Those in red usually require a service call.


  •     Outdoor unit iced up-weather related

  •     Snow drift/leaves against outdoor unit

  •     Outdoor unit not running, using back-up heat

  •     Dirty air filter

  •     Poorly insulate house/air leaks


  •     Outdoor unit not running, using back-up heat

  •     Low refrigerant charge

  •     Refrigerant flow related problem/restriction/defective-metering device.

  •     Defective reversing valve

  •     Bad compressor valves

  •     Running in A/C mode

  •     Outdoor unit iced up because of malfunction

Hope this has been of some assistance, however they are just rough guidelines and not all possible conditions are covered.
