Heat Pumps get a bad rap, but really they are very effective. Keep your thermostat set at a constant comfortable temperature and keep your fan set on ‘auto’, not ‘on’ so it is only blowing hot air. When the temperature outside gets really cold, like we had the past week when the daytime high was 20 degrees, flip your thermostat over to supplemental (or emergency) heat. It isn’t really ’emergency’ heat, and it won’t cost you any more. In fact, if you don’t change it to supplemental (or emergency) heat, your heat pump will actually cost you more money because it will be flipping back and forth between regular and supplementary heat. So when the forecast for the day is well below freezing, go ahead and turn your thermostat over to supplemental (or emergency) heat.
