Furnace Repair in Bolivar Peninsula, TX

The most common causes in Galveston are a failed sequencer (electric furnaces) or a failed igniter or flame sensor (gas furnaces). In electric furnaces, sequencers stage heating elements on in sequence. If the first-stage sequencer fails from salt corrosion, no elements activate and the blower pushes unheated air. In gas furnaces, a cracked igniter or corroded flame sensor prevents the burner from lighting or staying lit.

Usually, yes. After sitting idle for nine months in Galveston humidity, dust settles on heating elements. The first time they heat up, that dust burns off and produces a brief burning smell. It should clear within 30 minutes to an hour. If the smell persists, smells like melting plastic or rubber, or is accompanied by visible smoke, turn the system off and call for service. Those indicate an electrical or component problem.

If the furnace is under 15 years old and needs a single component replaced, repair usually makes sense. Common repairs run $100-$600 depending on the part. If the furnace is over 15-20 years old, has multiple failed components, or shows significant corrosion damage, replacement is usually the better investment. A new electric furnace runs $1,500-$3,500, and you should also consider a heat pump conversion for Galveston mild climate.

Most furnace repairs are completed in a single visit, typically within one to two hours. Our trucks carry the components that fail most often in coastal environments: sequencers, heating elements, capacitors, igniters, flame sensors, and control boards. For less common parts, we may need to order and return for a second visit, but we will give you a clear timeline upfront.

For gas furnaces, this is almost always a corroded flame sensor. The sensor cannot detect the flame properly due to salt-air oxidation, so the gas valve shuts down as a safety measure. For electric furnaces, a clogged filter or failed blower motor can cause the high-limit safety switch to trip, shutting the system down to prevent overheating. Both are common and repairable issues.
