Heat pumps have changed the way we think about climate control in our homes and businesses. It used to be simple: air conditioners cool, furnaces heat, and that was it. But then along came the heat pump concept, and the terminology changed … slowly. Even now, there remains some confusion between the terms heat pump vs AC.

What is a heat pump?

You might have heard the term "air conditioner with a heat pump." While that's not too far off the mark, it isn't exactly correct.

Heat pumps are air conditioners configured with the ability to reverse the air conditioning process and provide heat instead of cooling. Appearance-wise there is practically no discernible difference between a standard air conditioner and a heat pump. You might be able to spot the reversing valve - a horizontal brass pipe near the coil fins that allows a heat pump to function - but that's essentially the only visible difference.
