Furnace Blower Won't Turn Off? Common Causes: A CleburneHomeowner's Guide

Cleburne sits in Johnson County, and homeowners here, including those near the Cleburne downtown square, run into this exact topic regularly. Here's how we walk through it.

For Cleburne Homeowners

Cleburne ISD covers a wide mix of home styles and ages in Cleburne, and that variety is part of why we treat every visit as its own diagnostic rather than assuming what we'll find based on the neighborhood.

Cleburne, home to Cleburne ISD and Cleburne State Park, mixes a historic downtown square with newer residential growth on the city's edges. Older homes near downtown often have ductwork that wasn't designed for modern high-efficiency HVAC equipment, worth accounting for during any installation.

Cleburne FAQ

Is it bad to just leave the furnace fan running continuously?+

Not inherently. Some homeowners run the fan on "On" year-round intentionally for more even air circulation, and it doesn't damage the system. It does use more electricity than "Auto" mode, so it's mostly a preference and utility-cost tradeoff, not a safety issue.

Could a dirty filter really cause this?+

Yes. A severely clogged filter restricts airflow enough that the furnace can overheat internally, which can trigger the limit switch to keep the blower running as a safety response. It's one of the first things worth checking, and one of the cheapest to rule out.
