A yearly water heater tune-up and flush help prevent sediment buildup, which reduces efficiency, increases energy costs, and can lead to overheating or tank damage. By removing this buildup, your heater runs more efficiently, extends its lifespan from 6-8 years to 12-15 years, and prevents costly breakdowns. Regular maintenance also helps catch small issues early, avoiding expensive repairs or premature replacement, which can cost thousands. Keeping your water heater in top shape ensures reliable hot water, lower utility bills, and long-term savings.
