Common questions
Water Heaters FAQs
Q. How long does a water heater last?
A standard tank runs 8–12 years; tankless units often last 20+ with annual descaling. If yours is over 10 years old and leaking, replacement is almost always cheaper than repeat repairs.
Q. Tank or tankless?
Tankless gives endless hot water and saves space and energy, but needs correct gas sizing and venting. We measure your gas line and usage and tell you honestly which one fits your home and budget.
Q. Can you replace it today?
Often yes. Call us and we will confirm availability, give you a flat price on the phone and get a truck out — including nights and weekends for emergencies.
