The greatest advantage of heat pumps (or one of the greatest; they have several advantages) is that they can work as both cooling and heating systems. As the colder weather settles in for winter, you’ll turn your heat pump over to heating mode for the first time in many months. It’s not difficult to do: you simply adjust the thermostat so the temperature setting is higher than the temperature in the house and the heat pump will automatically switch over to provide heat.
But … what if it doesn’t? That’s why we have this blog post: for those times when something isn’t right and the heat pump either stays in cooling mode or it’s only sending out room temperature air.
