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 Union.
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.
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.
My water heater is making noise but still works — is that a problem?
Popping or rumbling sounds usually indicate sediment buildup at the bottom of the tank. It's not always urgent, but it's worth having flushed or inspected before it affects the unit's lifespan.
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.
