A: Most St. Petersburg homes use heat pumps instead of traditional furnaces because Florida winters are mild.

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.

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 St. Petersburg, furnaces in older and newer homes from the 1920s to 2000s are often 20+ years old and operate inefficiently. A new high-efficiency furnace cuts your Duke Energy bill during cold snaps and lasts for years with yearly maintenance. Electric heat pump conversion may be the better long-term move for Florida’s climate.
