You’re probably happy to read this headline, because it means summer is getting closer and you’re that much nearer to not needing your home’s furnace at all. (At least until toward the end of the year.) But when the warmer weather settles in and the furnace won’t have to run, should you shut the system down entirely?
The answer depends on the type of furnace installed in your house. The main reason to shut down a furnace for the season is to avoid energy waste or possible safety hazards, and this isn’t the same for all furnaces.
