Frequently Asked Questions
Do you handle both tank and tankless gas water heaters?
Many technicians in our network work on both. Call (877) 823-0233 to confirm availability for your specific unit type in Derry.
Why does my pilot light keep going out in Derry?
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.
How long does a typical gas water heater last?
Most tank-style units last around 8 to 12 years depending on water quality and maintenance. Tankless units tend to last longer with proper upkeep. A technician can assess your specific unit's condition.
