Furnace Repair in Tennessee: what's different
Furnace Repair across Tennessee depends on the climate (IECC climate zones 3–4). Furnaces in mixed climates run for several months, and ice storms or cold snaps put sudden load on them. Annual safety checks on burners, venting and heat exchangers are worthwhile.
In Tennessee specifically: winter cold snaps. Heat pumps rely on backup heat during deep cold, raising bills.
Tennessee licenses HVAC and mechanical contractors through the Board for Licensing Contractors; smaller jobs may fall under local licensing. Ask any contractor for their license number before work starts, and expect a written price for furnace Repair.
Common systems in Tennessee: Heat pumps, Gas furnace + central AC, Dual-fuel systems, Crawl space ductwork. Tell the contractor which one you have so they bring the right parts.

Why does my furnace turn on then off right away?+
The most common reason is a dirty flame sensor, which can't prove the flame so the board shuts the gas off. Other causes are a weak pressure switch or a blocked vent.
