Assuming your heat pump is working properly, never listen to any service technician who suggests “giving the heat pump a rest” unless you want to pay two or three times the cost on your electric bill.

Do not turn the heat pump off by switching to Em. True, the efficiency does decline slightly as the temperature goes down, but even at very cold, single digit temps, heat pump efficiency is impressive and always better than any other setting on your thermostat.

Heat pumps are tremendously efficient, even in cold weather. If you’re hearing these profound “truths” from your spouse, then they are absolutely true, but you might accidentally leave this blog open on the home PC. But if you’re hearing any of these myths from your heating contractor, you have some additional problems. Like, “A heat pump is not efficient in cold weather” or “Turn off the heat pump when it gets cold” or “Heat pumps are not designed for cold weather climates.” All myths! Hopefully you have only heard these misunderstood rants from neighbors or the “expert know-it-all” at work. So when the weather gets cold and your heat pump runs constantly, myths are born. If any of these machines did not cycle off as we expect, we would naturally think something is wrong.

The clothes dryer runs until the clothes are dry and then turns off with a friendly melody letting you know that it has completed its job. We have been conditioned to expect our appliances to cycle.
