Why will my furnace not ignite?

The most common causes are a failed ignitor, a dirty flame sensor, a bad gas valve, or a tripped safety switch. Our technician tests each component to find the exact problem.

What is a cracked heat exchanger?

The heat exchanger separates combustion gases from the air circulated in your home. A crack allows carbon monoxide to leak into your living space. This is a safety hazard that requires immediate furnace replacement.

How do I know if my furnace is producing carbon monoxide?

Signs include a yellow pilot light, soot around the furnace, headaches and nausea when the heat is running, and excess moisture on windows. Install carbon monoxide detectors and call us immediately if you suspect a leak.

How often should a furnace flame sensor be cleaned?

Flame sensors should be cleaned at least once per year during your annual maintenance visit. A dirty flame sensor is the most common cause of furnace ignition failures.

Why does my furnace make a banging noise at startup?

Banging at startup is usually caused by delayed ignition where gas builds up before lighting. This is a safety concern that should be inspected immediately.

How long do furnaces last in Louisiana?

Most furnaces last 15 to 20 years. Louisiana's humidity can shorten lifespan due to corrosion during the long idle summer months. Annual maintenance helps extend furnace life.

Signs You Need Furnace Repair

A furnace that will not ignite is the most common call we get in winter. Failed ignitors, dirty flame sensors, and gas valve problems all prevent ignition. A furnace that lights but shuts off after a few seconds is usually a flame sensor issue. Banging or popping sounds at startup can mean delayed ignition, which is a safety concern. A cracked heat exchanger leaks carbon monoxide into your home. Signs include a yellow pilot light, soot around the furnace, or family members having headaches and nausea when the heat is on. Rust or corrosion on the furnace body means moisture damage is weakening the unit. A blower that runs constantly without producing heat points to a relay or control board failure. These are not problems to ignore. Carbon monoxide is odorless and can be deadly.

Furnace Repair for Kentwood Homes

Furnaces in Kentwood and Tangipahoa Parish sit idle for months during our long, hot summers. When they finally kick on in late fall, ignitors can fail, flame sensors corrode, and heat exchangers crack from the sudden temperature change. Humidity also causes rust and corrosion inside the furnace housing during the off-season. TMAC is based in Kentwood and serves Amite, Hammond, Baton Rouge, Covington, Denham Springs, Ponchatoula, Walker, and McComb, MS. We recommend a furnace inspection before heating season starts to catch problems early.
