Northeast Energy Efficiency Partnerships also has a comprehensive list of cold-weather performance data for most heat pump models. If you’re worried about below-zero temperatures, your home almost definitely has a robust heating system installed already, and you might be a good candidate for a hybrid-heat or dual-heat system.

“It’s like pushing uphill.” Essentially, it’s harder for the heat pump to move the heat when it has to find that heat first-but again, that happens only in extreme conditions. “The colder it is outside, the harder it is for that machine to take heat from that air and move it inside,” explained Harvey Michaels, a lecturer in system dynamics and information technology at MIT Sloan.

But it also found that heat pumps designed and installed after 2015 kept functioning normally down to -13 degrees Fahrenheit-and in more moderate conditions, they were two to three times more efficient than standard electric heating systems. A 2017 study from the Minnesota-based clean energy nonprofit Center for Energy and Environment comparing older heat pumps with more recently designed ones showed that older heat pump systems were significantly less efficient in temperatures below 40 degrees Fahrenheit. Heat pumps have historically been more common in Southern states, and they’ve also had a bit of a bad reputation as being less efficient or failing entirely in colder weather. It’s a quality-of-life improvement.”īut it can still feel daunting to pick the heat pump that's right for you, or even to know where to start looking. And at the same time, they’re going to reduce our energy demand and our greenhouse gas emissions. But there are some places where everyone benefits, and I think heat pumps are a good example of that,” said Alexander Gard-Murray, PhD, a political economist at Brown University and co-author of 3H Hybrid Heat Homes: An Incentive Program to Electrify Space Heating and Reduce Energy Bills in American Homes. “We’ve come to see climate solutions like paper straws as being something worse than what we’re used to. In fact, most experts agree they’re one of the best ways for homeowners to reduce their carbon footprint and reap the benefits of a greener future without sacrificing comfort. They’re the cheapest and most efficient way to handle both heating and cooling for your home, no matter where you live (especially when you factor in the recent tax credits and incentives from the Inflation Reduction Act).
