At What Temperature Does A Heat Pump Stop Working? 20°F?

at what temperature do heat pumps stop working

“Heat pumps stop working at 20 degrees.” This is a common myth about heat pump minimum outdoor temperature. At what temperature does a heat pump actually stop working? Never. A heat pump will work even in extremely cold weather (even below freezing temperatures). We will look into the relationship between low temperatures and heat pump … Read more

Heat Pump Efficiency Vs Temperature Graph (0°F To 60°F)

Heat pump efficiency depends on outdoor temperatures. As we all know, at lower temperatures, heat pumps become less efficient. That’s why we usually use a furnace combo with heat pumps; at freezing temperatures, heat pumps become less effective, and we have to use the furnace for heating. How much does heat pump efficiency drops in … Read more
