Alvarado 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.

Does this apply to homes in Alvarado specifically?+

Yes. The guidance in this article applies to residential HVAC systems throughout Alvarado and the rest of our service area. If you want a read on your specific system, call us at (817) 935-8540 or request an estimate and mention you're in Alvarado.
