High Electric Bills:

Hannabery HVAC can lower your electric bills!

Like the previous complaint, if you are experiencing this problem in the cooling mode during the summer, you should probably call for service; assuming you have checked the obvious things - like an open window for example. This is for the most part, a winter-time heating complaint.

Many things can cause high electric bills. This includes a mistake from the electric company, a poorly insulated home, an open window, old, inefficient appliances such as electric water heaters, refrigerators and freezers, and of course, just wasting energy.

Ruling these things out, however, usually leaves just one culprit - the heating system, especially if it is a heat pump. The electric bill will naturally be higher in the coldest months because that is when your heat pump and the supplemental heat (electric resistance heat, also known as the Emergency Heat) runs the most. But if your electric bills are suddenly significantly higher than normal, it is almost always a sign of a problem with the heat pump.

This can range from minor things like a tripped breaker to the outdoor unit, or a very dirty air filter, or an iced-up outdoor unit, to severe problems like a damaged compressor.

Below is a list of possible causes. Items in red usually require a service call. Items in blue however can be addressed, some even fixed by the homeowner.

Red = Professional fix | Blue = Homeowner fix
toolbox for heating and air conditioning service and repairs
  • Outdoor unit not running, using back-up heat
  • Low refrigerant charge
  • Refrigerant flow-related problem - restriction/bad metering device
  • Poor efficiency- needs cleaning and servicing
  • Bad reversing valve
  • Bad compressor valves
  • Compressor not running
  • Running in A/C mode
  • Outdoor unit iced-up because of a malfunction
  • Undersized equipment and/or ductwork
  • Outdoor unit iced-up - weather related
  • Snow drift against outdoor unit
  • Outdoor unit not running - check breaker
  • Extremely dirty air filter
  • Return duct leakage - pulling in cold, unconditioned air
  • Poorly insulated house, air leaks

The bottom causes in blue are commonly found problems and can be addressed by the homeowner. Try to check for these conditions first before calling for service.
