Frequently Asked Questions
Why does my pilot light keep going out in Portsmouth?
The most common cause is a worn thermocouple, which is a relatively inexpensive part to replace. Drafts and a dirty pilot orifice can also cause this. A technician can usually diagnose it on the same visit.
What does gas water heater repair typically cost?
Cost depends on the specific part or issue involved — a thermocouple replacement is relatively inexpensive, while a gas valve or full tank issue costs more. Pricing is discussed directly with the technician after diagnosis.
Should I repair or replace my gas water heater?
It generally depends on the unit's age and what's failed. A control valve or thermocouple issue on a newer tank is usually worth repairing; a rusting tank near the end of its typical service life is often better replaced. A technician can advise after inspecting it.
Do I need to fill out a form before getting help?
No. Call (877) 823-0233 directly — there's no online form or waiting period before you're connected toward local help.
What should I do if I smell gas near my water heater?
Leave the house immediately, avoid operating any switches or appliances, and call your gas utility's emergency line from a safe location. This takes priority over calling for a repair.
