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

Aledo sits in Parker County, and homeowners here, including those near the Aledo Nature Preserve, run into this exact topic regularly. Here's how we walk through it.

For Aledo Homeowners

Between established neighborhoods and newer construction, Aledo has enough variety in home age and system type that we rarely assume anything about a system before actually looking at it.

Aledo sits in Parker County, just west of Fort Worth, and has grown steadily in recent years, in large part due to the reputation of Aledo ISD, whose football program and academic programs regularly draw families to the area.

That growth means a lot of relatively newer construction, though longer-established homes closer to Downtown Aledo are part of the mix too. Either way, Aledo homeowners get the same upfront pricing and clear communication before dispatch that our closer-in Fort Worth customers rely on.

Aledo 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.

Do you see this issue often in Aledo?+
