FAQ

Why do thermocouples fail?

Metal fatigue from repeated heating cycles. 2-5 year typical lifespan. Tampa intermittent use shortens it.

Can I replace it myself?

Technically possible but involves gas work. $279 pro with warranty is safer.

Gas smell, dangerous?

Leave the house immediately. Don’t use phones or switches inside. Call TECO (813-275-3700) + us.

Tampa homes still use pilot lights?

Older water heaters + some gas furnaces yes. Newer units have electronic ignition (no pilot).
