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

This investment covers the hardware and the specialized labor needed to mount the unit and connect it to your home’s utilities. Because tankless units are sensitive to water quality and flow, the installation process includes testing and calibration to prevent future issues.

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 Glendale

How long do hot water heaters typically last?

Most traditional tank water heaters are designed to last between 10 to 15 years. Tankless water heaters, which heat water on demand, can often have a longer operational life, sometimes up to 20 years or more with proper maintenance. Regular professional inspections can help maximize their longevity.

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 efficient. They heat water only when you need it, which means they don't waste energy keeping a large tank of water hot constantly. This can lead to significant savings on your utility bills. The pros can explain if this is a good option for your Glendale home.

What are signs I need a new water heater?

You should consider a new water heater if you're experiencing a lack of hot water, if the water temperature is inconsistent, or if you hear strange noises like rumbling or popping. Visible leaks around the unit or a significant decrease in hot water pressure are also clear indicators that replacement may be necessary.

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

A frequent issue is a lack of hot water, which can be caused by a tripped thermostat, a pilot light that won't stay lit, or sediment buildup in the tank. Strange noises, often described as popping or hissing, are also common and usually indicate sediment in the tank. These can typically be fixed by a pro.

Is it worth it to repair a hot water heater?

Repairing a water heater is often a sensible choice for smaller issues, especially if the unit is relatively new. Problems like a faulty heating element or a minor leak can usually be addressed cost-effectively. However, if the tank itself is showing signs of rust or the heater is old, replacement might be a better long-term investment.
