FAQ

Questions, answered.

  • If your tank is under 8 years old and the problem is a thermostat, element, or valve — repair almost always wins. Past 10 years, leaking from the tank itself, or hit by sediment damage, replacement is usually the smarter call. We'll quote both side by side.
  • Tank is cheaper up-front and simpler to service. Tankless gives endless hot water and lower monthly energy use, but the Gulf Coast's hard water means you must flush it every ~6 months to keep the warranty alive.
  • Most standard residential tanks are swapped same-day if we have the size in stock — usually within 4–5 hours of arrival. Tankless installs typically take a full day.
  • Yes — every ~6 months along the Gulf Coast. We descale, replace inline filters, and document the service so your warranty stays valid.
