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

Replacing a water heater involves disconnecting your current unit, hauling it away, and installing a new model that fits your space and capacity needs. Costs are influenced by the type of unit you choose—tank or tankless—and the necessary code upgrades for your plumbing. If your current unit is leaking or failing to heat properly, it is time for a swap.

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?

Most tank-style water heaters in Tempe typically last between 8 to 12 years. The hard water common in Arizona can sometimes accelerate sediment buildup, impacting lifespan. Regular flushing can help prevent this. If your unit is approaching this age, consider a professional inspection.

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

What is the most efficient type of water heater?

High-efficiency tankless water heaters are generally considered the most energy-efficient option available. They heat water on demand, avoiding the standby energy losses associated with traditional tank models. A professional can help you choose the right size and type for your Tempe household's needs.

What are signs I need a new water heater?

Key indicators include a noticeable decrease in hot water availability, unusual noises like popping or rumbling, and any visible leaks around the base of the unit. If the water coming out is rusty or discolored, it's a strong sign. Age is also a factor; most units last 8-12 years.

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

Sediment buildup within the tank is a very common issue, leading to noise and reduced heating efficiency. Corrosion of the anode rod, which protects the tank from rust, is another frequent problem. Pilot light issues or thermostat malfunctions can also occur, disrupting hot water supply. Regular maintenance helps.

Is it worth it to repair a hot water heater?

Repairing a water heater is often a wise choice for newer units with minor issues, such as a faulty thermostat or heating element. However, if the tank itself is leaking or the unit is nearing the end of its typical lifespan, replacement usually becomes the more cost-effective option in the long run. A professional can offer guidance.
