What affects the price

The final price for a new water heater depends on a few moving parts. First, you have to choose the right fuel source—gas or electric—and decide if you want to stick with a standard tank or upgrade to a tankless model. We also look at the physical space where it sits and whether your current venting or gas lines meet modern safety codes. If we need to move the unit or upgrade plumbing to get it up to speed, that shifts the labor involved. Exact pricing confirmed free on the call.

About this service

Navien units are sophisticated systems that require specialized knowledge to troubleshoot. If your unit displays an error code, has reduced flow, or fails to ignite, a technician should inspect the heat exchanger and sensors. You typically need this service when the water temperature fluctuates or the unit stops responding entirely. Proper maintenance ensures these high-efficiency systems continue running as intended. Exact pricing confirmed free on the call.

While you might not think about hot water as much in the summer, it is a great time to evaluate your system’s health. Because the incoming groundwater is warmer, your heater doesn't have to work as hard, making it a stress-free window to replace an aging unit before you hit the busy autumn season.

What is the average cost of putting in a water heater?

What is the most efficient type of water heater?

Tankless water heaters, including high-efficiency Navien models, are generally the most energy-efficient. They heat water on demand, eliminating standby energy losses common with tank heaters. This can lead to significant savings on your utility bills in a large metropolitan area like Phoenix.

What are signs I need a new water heater?

Look for indicators such as a lack of hot water, discolored or rusty water, unusual noises, or visible leaks. If your water heater is approaching its expected lifespan, these issues often signal it's time for a replacement. A licensed pro can assess your unit's condition.

What is the most common problem with a hot water heater?

Is it worth it to repair a hot water heater?
