With temperatures dipping into the 50’s at night this past week, you might have decided to use your heater. True, we use it very briefly around our area, but given the contrast in temperature, it can be quite chilly at night without a reliable heating system! So, what if you’re using a heat pump, and all it will do is blow out cold air?
The first thing you want to do if this happens is to check the thermostat to ensure that you actually have it set for heating mode. This may seem apparent, but there’s always a chance that a family member switched it back over, preferring a different temperature than you. Assuming you’ve checked this and the heat pump is blowing out cold air when you’ve switched it over to heat, it likely means that your heat pump is actually stuck in cooling mode, despite what your thermostat is saying. But, how does this happen?
