Air-source heat pumps are typically installed with a back-up electric power source.

Answer: True
Explanation: True. Air-source heat pumps are typically installed with a back-up electric power source, especially in regions that experience colder winters. While air-source heat pumps are efficient for heating and cooling, their performance can decrease in very low temperatures. In such cases, a back-up heating system (usually electric resistance heat or a gas furnace) is often integrated to ensure consistent heating when the air-source heat pump alone cannot maintain the desired temperature. This back-up system kicks in when the heat pump’s efficiency drops, ensuring the home remains warm even during extreme cold spells. Many modern heat pumps are designed to automatically switch to the backup system when necessary, providing reliable comfort throughout the year.

Answer: True
Explanation: They tend to go out in extreme weather

Answer: True
Explanation: When your heat pumps goes into defrost your back up heat comes on to help warm the air while defrosting.

Answer: True
Explanation: In colder climates this helps with those days that the heat pump can't produce heat from outside. It also helps when the system go in defrost mode or it is needing a hire demand in tempature.

Answer: False
Explanation: Here in Phoenix we do not install back up heat because our winters are so mild.

Answer: True
Explanation: While electricmis the typical back up source I prefer using a Dual fuel sytem which would use natural gas or LP.

Answer: True
Explanation: Typically, yes. But, the new controls available today allow for the high efficient gas furnace to be installed as a back-up to the heat pump.

Answer: True
Explanation: All electric is the standard heat pump design

Answer: True
Explanation: This provides additional heat when you turn the thermostat up more then four degrees.

Answer: False
Explanation: Not here in the north. Backed up with gas, Oil or fossil fuel

Answer: True
Explanation: But I would recommend using a gas furnace as backup if it is readily available.

Answer: True
Explanation: With a air to air heat pump you will have an emergency back up heat source it can vary from natural gas, LP or electric . Depending on your geoligical location you may not need emergency heat, a typical air to air heat pump runs efficiently and puts out good heat down to 25 degrees. If you live in a warmer climate where the temps dont get below freezing than you wouldnt need any type of - emergency heat.

Answer: True
Explanation: capacity goes down with temps in winter

Answer: True
Explanation: This is historically true. Today heat pumps operate more efficiently and with greater capacity in the lower outdoor temperature range thanks to better computer control. Split ductless units rarely have electric resistance heating coils and still perform well when its cold outside and you need it most

Answer: False
Explanation: depending

Answer: True
Explanation: When temperatures drop, the back-up electric power source will prevent cold air from blowing into your home during the winter.
