Why is my heat pump always running on emergency heat in the winter?
Heat pumps frequently switch to expensive auxiliary or emergency heat during cold months, causing winter electricity bills to skyrocket to $600 or even $950. This forces homeowners to keep their thermostats as low as 65 degrees while still dealing with freezing temperatures and unaffordable power costs.

“The heat pump which is only supposed to heat the top floor, goes into “emergency heat” mode for basically the entire winter (low avg 32-35 F for Dec-Mar). The bills are outrageously high ($600 just for electric).”source ↗
“We already have the whole house set to 65 in the winter (and we all are cold all winter long).”source ↗
“In winter, if we have a cold snap and it runs 80% of the time on heat though, bills are way higher…like $950.”source ↗
