6 Common Myths and Facts About Heat Pumps

Updated: Sep 21, 2021

An increasing number of homeowners are installing heat pumps because they offer highly efficient heating, air conditioning, and dehumidification. Heat pumps help lower your utility bill, while providing comfortable indoor temperatures year-round. Unfortunately, there are still misconceptions about heat pumps. So let’s dispel six common myths with industry facts.

Myth #1: Heat pumps can’t handle cold outdoor temperatures.

Fact: Modern heat pump technology can provide reliable, efficient heat when outside temperatures are as low as zero degrees Fahrenheit, while some heat pumps even work at temperatures below zero.

Myth #2: Heat pumps aren’t as efficient in cold climates.

Fact: While they may lose some efficiency in extreme cold temperatures, heat pumps are far more efficient than furnaces and boilers—boasting nearly 200% efficiency at temperatures as low as zero degrees Fahrenheit.

Myth #3: Heat pumps only work in newer, well-insulated homes.


Fact: As with anything, you need the right size tool for the job. A properly sized heat pump can be used to heat your living space, regardless of insulation or the age of your home.

Myth #4: You have to turn down your heat pump at night to save energy.

Fact: Heat pumps save the most energy when they’re kept at a consistent temperature. For maximum efficiency from your heat pump, program your thermostat at a regulated temperature. We recommend you “set it and forget it”.

Myth #5: You have to leave your heat pump on to prevent it from leaking or your pipes from freezing.

Fact: With boiler heat, you have to leave your boiler on to prevent your pipes from freezing, but with a heat pump that’s not necessary. There are no water pipes that can freeze with a power outage or if the temperature drops below freezing.

Myth #6: Heat pumps require too much maintenance.


Fact: A heat pump requires routine maintenance and regular tune-ups but not any more than a traditional furnace, boiler or central AC system. Regular maintenance checks are important to keep any system running at peak performance and prevent costly emergency repairs.
