Why is My Furnace Fan Always On?

5.0 Rating

small_3721247390The fan is one of the loudest parts of your furnace, so you can almost always tell when it’s running. That’s why it can be concerning when your thermostat says your home is at the right temperature but the sound of your fan running never seems to disappear. Today we’re going to explain a couple of reasons why this might be happening by answering the question, “Why is my furnace fan always on?”


Why is my furnace fan always on?





Prevent fan problems with annual tune-ups


If you want to keep your furnace’s fan running properly, it’s important to schedule annual tune-ups for your furnace. During your tune-ups, we’ll inspect your system for any problems like a malfunctioning limit switch that might cause your furnace fan to always be on. In addition, we can answer any questions you might have about why your furnace fan runs too frequently.


If you have any questions about why your furnace fan is always on, or if you’d like a heating system serviced or installed in your home, contact Jerry Kelly, your St. Charles, MO, furnace installation and repair contractor. We service the St. Louis area, including towns like St. Paul, St. Peters and Town and Country, MO.
