What affects the price

When you are looking at the price of a new water heater, a few main things shift the final number. The type of unit you choose—whether it is a tank model or a tankless system—is the biggest factor. You also have to consider the fuel source, like gas or electric, and the physical space where the heater sits. If your home needs new venting, updated piping, or a different hookup to meet current safety codes, that adds labor time to the project.

About this service

Even though it is warm outside, your water heater is still working daily. Summer is a great time to adjust your settings, as the incoming water isn't as cold, which can actually help extend the life of your unit. If you are planning a home renovation or just want to upgrade to a more efficient model, call us to talk through your options.

Frequently asked in Tempe

How long do hot water heaters typically last?

For Tempe residents, most tank-style water heaters typically last between 8 to 12 years. The lifespan can be influenced by water quality and usage patterns. If your water heater is showing signs of age or experiencing frequent issues, it might be more cost-effective to consider a replacement. We can help you determine the best course of action.

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 for Tempe homes. They heat water on demand, meaning you only use energy when hot water is needed, unlike traditional tanks that continuously maintain a water temperature. This can lead to significant savings on your utility bills over time.

What are signs I need a new water heater?

You might need a new water heater in Tempe if you're experiencing a reduced supply of hot water, hearing strange noises like rumbling or popping, seeing rust on the tank or pipes, or noticing water leaks. These are clear indicators that your current unit is aging and may require replacement. Professional assessment is advised.

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

Sediment buildup is a very common problem for water heaters, especially in areas with hard water like Tempe. This buildup can reduce heating efficiency, create noise, and eventually lead to tank corrosion. Regular flushing can help, but persistent issues may signal the need for professional service or a new unit.

Is it worth it to repair a water heater?

Whether it's worth repairing a water heater in Tempe depends on its age and the nature of the problem. Minor repairs on a newer unit are often cost-effective. However, for older water heaters or significant issues, replacing it with a new, more efficient model might be the more economical choice in the long run. We can provide an assessment.
