Common Questions

How long do water heaters last? Tank water heaters typically last 8-12 years. Tankless units can last 15-20 years or more. Annual maintenance helps extend the life of either type.

Should I repair or replace? If the repair costs more than half the price of a new unit and your water heater is over 10 years old, replacement is usually the smarter move. We'll always give you both options.

Is tankless worth it? Higher upfront cost, but lower energy bills and a longer lifespan. It's a good fit for larger households or homes with high hot water demand. We can help you decide.

What size water heater do I need? Depends on household size and usage. A 40-gallon tank works for 2-3 people, while 50 gallons or more is better for families of 4+. We'll help you size it during the assessment.

How long does installation take? A standard tank replacement takes 2-4 hours. Tankless installations can take longer if gas line or venting modifications are needed.
