Frequently Asked Questions
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.
Why does my pilot light keep going out in Chelmsford?
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.
