Heat pumps are great. Instead of using a separate air conditioner and furnace to manage your comfort around the year, you only need a single system that can provide heating and cooling. And it works the same way, no matter if it’s in heating mode or cooling mode: the only difference is the direction the refrigerant moves. In one direction, the refrigerant moves heat from inside and releases it outside (cooling). In the other, it moves heat from outside and releases it inside (heating).
We’re at the time of the year when you’re going stop using the heating mode on the heat pump, and will eventually change the setting on the thermostat to “cooling.” But what do you do if you change your heat pump over to cooling—and you don’t get cool air from the vents?
The changeover to spring doesn’t mean the permanent arrival of warm weather, no matter how much we’d like that. But warmer days are here, and the heater in your home will put in less and less work over the coming weeks until it finally turns off for the middle of the year, not coming back to work until fall.
It can be a sudden shock when your furnace turns on during these last cold days of the season and it makes a loud boom sound. You expect to hear a distinct noise when the gas jets on the burner assembly ignite each time, but when the sound becomes something that makes people jump, it can be alarming.
