Heat Pump & Precisely what For you to Seem With regard to To Preserve & Upkeep Your Heat Pump - Nearby Support Center

A heat pump normally takes heat externally and moves it in your house.  Even chilly winter air has some heat, and heat pumps can extract heat from the outside air on a cold day and move it indoors to manage a comfy temperature.  It does this by operating as a refrigeration system - essentially an air-conditioner running in reverse.  If the heat pump is acquiring heat from the outside air, the efficiency of the heat pump lessens as the outdoor air temperature reduces. The colder it is, the more challenging it gets to extract and move heat.

The efficiency of a heat pump differs substantially with the outdoor climate. While a heat pump may be twice as efficient as a regular heating system at 50 degrees F, when the outdoor climate drops to less than 30 degrees, extra electric resistance heating kicks in.  At very low outdoor temps, the heat pump compressor will shut off completely and the backup heating system takes over - using much more electricity.  Most smart thermostats support many stages of heating and cooling, and can run the heat pump and auxiliary heat simultaneously to optimize comfort and minimize overall energy costs.

In case of compressor or general system failure, a lot of thermostats have an emergency heat switch that bypasses the thermostat and triggers the supplemental heater.  You may have noticed that after a power outage, the supplemental electric resistance heater runs for a while to warm up the house.  This is normal, as the system is designed to reheat the oil in the crankcase of the compressor before restarting the compressor.

If you notice that your system is heating but the outdoor compressor is not working, or if the emergency heat light is on, there could be several factors for this.  The power might be off to the outdoor unit because of a blown fuse or tripped circuit breaker.  A very filthy air filter, or dirt on the outside unit could also be the main problem.  Extreme changes to the settings on the thermostat might also drive the system into emergency heating mode.

If the auxiliary or emergency heat light is always on when the unit is heating, there is probably some problem with the system.  A service professional can quickly check if the system is low on refrigerant, or if there is a more serious problem. Keep an eye on your thermostat light and your system, as well as your electric bill.  If there is an increase in electrical usage for no apparent reason, you may have a heat pump working on costly backup electric resistance heat.
