A: Furnace blowing cold air is usually one of four issues: thermostat set to fan-on instead of auto, a dirty filter restricting airflow, a failed ignition or pilot (gas furnace), or a tripped safety limit switch. In Keystone, where furnaces run only a few weeks a year, dust accumulates inside and causes ignition issues.

A: Use the age times repair cost rule. If your furnace is over 15 years old and needs a repair costing more than $500, replacement usually makes sense. In Keystone, furnaces in mixed (ranch homes on acreage, newer builds) homes from the 1970s to 2010s (mixed) are often 20+ years old and operate inefficiently. A new high-efficiency furnace cuts your TECO bill during cold snaps and lasts 15 to 20 years. Electric heat pump conversion may be the better long-term move for Florida’s climate.
