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

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.

Frequently asked in Tempe

How long do hot water heaters typically last?

Standard tank water heaters typically last between 8 to 12 years. Tankless models, with proper care, can often extend their service life to 20 years. The quality of your water and regular maintenance are significant factors. The specialist you'll speak with can offer tailored advice.

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

What is the most efficient type of water heater?

Tankless water heaters are generally considered the most energy-efficient option available. They heat water only when it's needed, eliminating the energy waste from keeping a large tank of water consistently hot. This can lead to substantial savings on energy bills. Ask about tankless systems when you call.

What are signs I need a new water heater?

Look for signs such as discolored or rusty hot water, unusual noises like banging or hissing, and any visible leaks around the unit. If your hot water supply is inconsistent or depletes quickly, it's also a strong indication. These symptoms often suggest replacement is necessary.

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

Sediment accumulation at the bottom of the tank is a frequent issue that can decrease efficiency and cause noise. Another common problem involves the pilot light or igniter failing to operate correctly. Regular flushing of the tank can help prevent sediment-related problems.

Is it worth it to repair a hot water heater?

Repairing a relatively new water heater for minor issues is often a good financial decision. However, if your unit is older and requires a significant repair, investing in a new, more efficient model might be more cost-effective in the long run. The pro can provide an expert assessment.
