What is the lowest temperature a heat pump will work?

Heat pumps do not operate as efficiently when temperatures drop to between 25 and 40 degrees Fahrenheit for most systems. A heat pump works best when the temperature is above 40. Once outdoor temperatures drop to 40 degrees, heat pumps start losing efficiency, and they consume more energy to do their jobs.

Why is my emergency heat blowing cold air?

Defrost mode basically means your heat pump temporarily switches to cooling mode. This forces the outdoor coils to heat up, melting any frost or ice that has built up. And because the heat pump switched to cooling mode, it will blow cold air into your home for a few minutes.

How long does it take for emergency heat to kick on?

This is where emergency heat comes in. Typically, this setting on your thermostat kicks on when the temperature is anywhere between 30 to 35 degrees Fahrenheit. How your emergency uses this air differs from the normal way that your heat pump usually functions.
