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

If your home has a furnace, we service, repair, and replace it with options ranging with FREE diagnosis repairs to $4,500 to $7,500 for full replacements.

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 St. Petersburg, where furnaces run only a few weeks a year, dust accumulates inside and causes ignition issues. Our HVAC techs carry license CAC1819196 and most no-heat fixes in Old Northeast, Shore Acres, Tyrone are same-day at $279 to $475.

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 mixed (historic bungalows, concrete block, modern) homes from the 1920s to 2000s (mixed) are often 20+ years old and operate inefficiently. A new high-efficiency furnace cuts your Duke Energy 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.
