Is the NEEP cold climate heat pump list still the best?

A homeowner on a building-science forum recently asked whether the NEEP cold climate heat pump list is still the best place to compare heat pump equipment, after being away from the topic for a few years. The NEEP list, maintained by the Northeast Energy Efficiency Partnerships, has long been a reference for finding heat pumps that keep working efficiently in cold weather, since not all heat pumps perform well once temperatures drop well below freezing.

The question was posted without any replies yet, so there is no new verdict on whether the list has been replaced or updated, or what alternatives might exist. If you are shopping for a heat pump and want to check cold-weather performance, the NEEP list has historically been a starting point, letting you compare rated output and efficiency at low outdoor temperatures across brands and models.

For now, this is simply an open question in the homeowner and builder community rather than a confirmed change to any program or tool. If you are considering a heat pump for your own home, especially in a colder climate, it is worth checking whether the list still reflects current equipment, or asking a local installer or your state energy office what resources they recommend for comparing cold-climate performance before you buy.
