Water Heater Installation & Maintenance

Choosing and installing a water heater

Tank and tankless water heaters each suit different households, and the right choice depends on hot water demand, available space, and fuel type. Standard tank units from manufacturers like A.O. Smith, Rheem, and Bradford White offer straightforward installation and lower upfront cost, while tankless systems from brands such as Rinnai deliver continuous hot water and a smaller footprint in exchange for a higher initial investment and different venting requirements.

A technician evaluates your home's gas line or electrical capacity, venting path, and recovery needs before recommending a specific model and size. Recovery rate, meaning how quickly a tank reheats water after use, matters as much as tank size for larger households, and this gets factored into the recommendation rather than simply matching the old unit's capacity.

Replacement estimates are always free, and the price is written down before installation begins. Installation includes removing the old unit, setting the new one, connecting gas or electrical and water lines, and testing for proper operation and leak-free connections.

Maintenance that extends water heater life

Sediment buildup inside a tank water heater reduces efficiency and shortens its lifespan, which is why a periodic flush matters, particularly in areas with hard water. Tankless units also need regular descaling flushes to prevent mineral buildup inside the heat exchanger from reducing performance over time.

Iron Horse Advantage members receive a standard water heater flush included in their membership, with a tankless flush available for $89 for members who have a tankless system. Outside of membership, flushes and inspections can be scheduled individually, and a technician will also check the anode rod on tank units, since a depleted anode rod is one of the most common reasons tanks fail early from internal corrosion.

Water heater repairs follow the standard $120 diagnostic fee, waived when you proceed with the repair, which applies to issues like pilot light failures, heating element problems, thermostat malfunctions, or leaking tank fittings.

Warranty, financing, and support

New water heaters carry the manufacturer's warranty on the tank and components, separate from the workmanship warranty on the installation itself. Keep your invoice along with the model and serial number of the installed unit, and call the shop first if a warranty issue comes up, with the symptoms and your equipment details available. The cause needs to be identified before coverage can be discussed.

For a full replacement, financing is available through home-service lenders, including 0% promotional options for qualifying, approved credit, with applications typically processed in minutes and work scheduled once approved. Call the Tempe shop at 1917 E 5th St or (480) 808-9990 to discuss tank versus tankless options for your household.
