What Changes the Price

• Tank size. A 50-gallon unit costs more to install than a 40-gallon, both in equipment and labor.
• Package level. Standard, Deluxe, and Premier differ mainly in warranty coverage (see below) — that's what separates the price tiers, not the tank itself.
• Installation location. A straightforward garage swap costs less than a unit tucked in an attic or a tight closet, where access adds labor time.
• Age and condition of the existing setup. Older installations sometimes need code-required updates (venting, straps, expansion tanks) done at the same time, which adds to the job.
• For repairs — which component failed. A simple part (a thermostat or a relit pilot) costs far less than a major component like a gas control valve.

Included at No Extra Cost

• Deluxe package: lifetime tank warranty (tank only — parts and labor not included). Also includes 8 annual maintenance visits.
• Premier package: lifetime tank, parts, and labor warranty — if the unit ever fails, it's replaced at no charge, per Moffett's own site. Also includes 10 annual maintenance visits AND replacement of sacrificial abode rods during the warranty period

A Note for Orange County Homeowners

• Orange County's water runs hard, in the range of 12-25+ grains per gallon depending on the area, and coastal cities like Newport Beach typically see lower mineral content than inland areas like Anaheim Hills or Yorba Linda. That hardness is a real factor in how long a tank lasts here versus the national average.
• Water departments throughout Southern California add chlorine to drinking water to disinfect it and protect public health by killing harmful bacteria, viruses, and other microorganisms. A residual level of chlorine is maintained as water travels through miles of distribution pipes to help prevent contamination before it reaches your home. While this disinfection is essential for safe drinking water, chlorine can contribute to corrosion in plumbing systems and may accelerate deterioration of certain water heater components over time.
• Regular water heater maintenance is especially important in areas with high chlorine levels and hard water, as chlorine can accelerate corrosion while hard water causes mineral and sediment buildup that reduces efficiency and shortens the tank’s lifespan. Annual tank flushing helps remove accumulated sediment, while inspecting and replacing the sacrificial anode rod as needed helps protect the tank from corrosion and premature failure. Routine maintenance can extend your water heater’s life, improve efficiency, reduce the risk of unexpected breakdowns, and help protect your investment.

Repair or Replace?

A water heater in the 8-12 year range that needs a major component repaired (like a gas control valve) is often a close call between fixing it and replacing it — the closer the repair cost gets to a meaningful fraction of a new install, the more replacement starts to make sense. A unit under warranty, or one that just needs a minor part, is usually worth repairing outright.

Signs You Should Call a Pro

• No hot water, or hot water that runs out much faster than it used to
• Rusty or discolored water coming from the tap
• Water pooling around the base of the tank
• Popping or rumbling sounds from the tank (often sediment buildup)
