Why Does My Furnace Keep Turning Off and On?

Short cycling—when a furnace turns off and on repeatedly—wastes energy, stresses parts, and usually means something simple needs attention. Homeowners in Minnesota see this most when temperatures swing or filters clog. Most furnaces short cycle because of restricted airflow (dirty filter), an overheating safety shut‑off, a mis-sized system, or thermostat/pressure switch issues. Replacing the filter […]

Can a Dirty Furnace Filter Cause No Heat in Your Home?

Can a dirty furnace filter cause no heat? In many cases, yes—restricted airflow can trigger safety limits and shut down heat production. A clogged filter can block airflow, overheat the heat exchanger, trip the high-limit switch, and leave your home without heat; checking and replacing the filter often restores safe operation in minutes.
