What Temperatures Is Too Low For A Heat Pump?

A heat pump works best when it’s not too cold outside, just like how you can’t blow warm air on your hands if you’re already wearing mittens.

Heat pumps are like smart blankets that pull warmth from the air, even when it's chilly. But they need a little help to do their job. When it gets too cold, the heat pump has trouble finding enough warmth in the air, kind of like trying to find a warm spot on a very cold day.

Think about your favorite drink. If you put ice cubes in it, it gets colder. A heat pump is like that, when the outside temperature drops too much, the “ice” (cold) makes it harder for the heat pump to do its job.

Most heat pumps start having trouble when the temperature goes below 20°F (-6°C). That's about how cold it feels on a really chilly morning. At this point, they might need help from another source of heat, like a furnace or electric heater, kind of like getting extra blankets to stay warm.

So, if it’s too cold for the heat pump to work well, you’ll feel it, your house won’t be as cozy as usual! A heat pump works best when it’s not too cold outside, just like how you can’t blow warm air on your hands if you’re already wearing mittens.
