Navien tankless water heater repair — Tempe, AZ

Traditional tank water heaters typically last 10-15 years, while tankless models, like many Navien units, can often reach 20 years or more with consistent maintenance. The mineral content of your water and how heavily the unit is used can also affect its lifespan. Regular professional check-ups are recommended.

Tankless water heaters are generally considered the most energy-efficient option. They heat water only when you need it, eliminating the energy waste associated with keeping a large tank of water hot constantly. This can lead to significant savings on your utility bills in Tempe over the unit's lifespan.

Look for a noticeable decrease in hot water supply, strange noises like popping or rumbling, or visible signs of rust and leaks around the unit. If your water heater is approaching or has exceeded its typical lifespan, it's a good time to consider a replacement to avoid unexpected failures.

Sediment buildup is a frequent issue, especially in areas with hard water, which can reduce efficiency and cause noise. For tank heaters, thermostat or heating element malfunctions are common. Tankless units can sometimes experience problems related to clogged filters or vent blockages.

Repairing a water heater is often worthwhile for newer units experiencing minor issues. However, if you have an older unit that requires extensive repairs, the cost might be better invested in a new, more energy-efficient model. A professional assessment can help you determine the most cost-effective solution for your Tempe home.
