Furnace & Heating Repair — San Antonio, TX
Most San Antonio homes will need a furnace & heating repair at some point. Best to have a name in your phone before you do. We answer the phone, give you a real quote before any work starts, and bring the right tools the first time.
Scope of work
Heating-side repairs run different than AC. Most furnace calls come down to ignitor failure, flame sensor, control board, or pressure switch. Heat pumps add reversing valve and defrost board.
Gas furnace ignitor failures are the most common winter call — about 40% of no-heat calls. The ignitor is a $35 part and a 20-minute job; total flat-rate runs $185-$340.
Heat pump no-heat in cold weather usually means failed reversing valve solenoid (system stuck in cool mode) or failed defrost board (outdoor coil iced up). Both diagnoseable in under an hour.
Older furnaces (15+ years) develop heat exchanger cracks. We check for them every diagnostic visit because a cracked heat exchanger leaks carbon monoxide and is a replacement-not-repair issue.
