FAQ

Water Heaters Questions

Should I Repair Or Replace My Water Heater?
If your unit is under about 8 years old and the issue is a part, repair usually makes sense. If it is older, leaking from the tank, or failing repeatedly, replacement is typically the better value. We will give you an honest recommendation.
Tank Or Tankless — Which Is Better?
Tankless units save space and deliver endless hot water with lower standby energy use, but cost more upfront. Tank heaters are cheaper to install and simpler to service. We help you weigh it for your home and usage.
How Long Do Water Heaters Last?
A typical tank water heater lasts 8 to 12 years; tankless units often last 20 years or more with maintenance. Hard water shortens those numbers, so flushing helps.
Why Is My Water Heater Leaking?
It could be a loose fitting, a failing valve, or — most seriously — a corroded tank. We diagnose the source; a tank leak almost always means replacement, while fittings and valves can often be repaired.
Do You Offer Financing On A New Water Heater?
Yes. Water heater replacement qualifies for our financing and payment-plan options, so an unexpected failure does not have to be paid all at once.
