This used to be the case but is no longer true.
The heat pumps offered in New England are made with cutting-edge technology, and are certified based on their performance at 5°F, and can even perform at -13°F. Heat pumps indeed become somewhat less efficient at temperatures below 5°F, but they do supply heat even when it is bitter cold. People in Maine and Vermont have installed over 40,000 cold climate heat pumps since 2013, and both states have colder winters than here in Massachusetts.
