Water Heater Maintenance in Milpitas, CA

How do you make a water heater last longer?

Have it maintained at least once a year and keep an eye on it between visits. Over time, minerals in the water settle in the tank or build up as scale inside a tankless unit. That makes the water heater work harder and can shorten its life. Regular flushing and a quick inspection go a long way.

What’s included in water heater maintenance?

Every visit is a full check of the system. Here is what our technicians do:

• Visual inspection. We look for rust, leaks, corrosion and other signs of wear on the tank, fittings and connections.
• Flush. We drain and flush a tank water heater to clear sediment, or flush a tankless unit to remove mineral scale.
• Valve and control testing. We test the thermostat and the valves, including the pressure relief valve, a safety part that lets out water if pressure gets too high.
• Clean and tighten. We clean and tighten parts as needed, and point out anything that should be replaced.
• Final test. We confirm the water heater is heating properly and running safely before we leave.

If we find a part that needs replacing, you get the price before any work begins. Nothing is done without your OK.

How much does water heater maintenance cost?

Service	Price	Comfort Club members
Tank water heater maintenance (flush)	$135	15% off
Tankless water heater maintenance (descale)	$150	15% off

Both include the full inspection, valve and control tests and a final check. A tankless descale circulates a cleaning solution through the unit to dissolve the mineral scale inside. If we find a part that needs replacing, you get the price first. Members of the Comfort Club save 15% on water heater maintenance.

How often should a water heater be flushed?

At least once a year. Homes with older water heaters may benefit from more frequent service. Tankless water heaters need regular flushing too, because scale can build up inside the heat exchanger (the part that heats the water) and reduce how well it works.

What are the signs a water heater needs service?

What you notice	What it can mean
Rumbling or popping sounds	Sediment has built up at the bottom of the tank
Running out of hot water sooner	Sediment, a failing part or a unit too small for your household
Water that isn’t as hot as before	Thermostat, burner or heating element problem
Rusty or discolored hot water	Corrosion inside the tank
Moisture or drips around the base	A leaking fitting or valve, or a tank that is starting to fail
Tankless unit showing an error code	Can point to scale buildup or another problem a technician should check

If your hot water supply was fine until recently and your household’s use hasn’t changed, something has likely gone wrong. That is a good time to call.

What can I check between maintenance visits?

• Look around the base of the water heater for drips or moisture every month or so.
• Keep the area around it clear of boxes, paint and cleaning supplies.
• Test your carbon monoxide detectors twice a year if you have a gas water heater.
• Never ignore a gas smell. Leave the home and call PG&E or 911.

Please leave draining, valve testing and burner work to a technician.

Is maintenance worth it on an older water heater?

Often, yes. Maintenance can keep an older unit running well and help you spot problems early. If we find a leaking tank or heavy corrosion, we will tell you honestly, and we can talk through water heater replacement options. A working water heater does not have to be replaced because of the Bay Area’s new water heater air rule. As of November 2026, the Air District says the rule applies only when a water heater is replaced. See the Air District’s building appliances page for details.
