Water heater service involves the maintenance, repair, or replacement of water heaters to ensure a reliable supply of hot water. Common issues include insufficient heating, strange noises, leaks, or rusty water. Regular maintenance, such as flushing the tank to remove sediment buildup, checking the thermostat, and inspecting valves, helps extend the water heater’s lifespan and improve efficiency. Professional technicians can diagnose and fix issues like faulty heating elements or temperature control problems. In some cases, replacing an old or inefficient water heater with a new, energy-efficient model may be recommended. Proper water heater service ensures consistent hot water and reduces energy costs.
