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

When calculating the cost of a tankless water heater and the labor to install it, we consider the unit's flow rate and your home’s existing utility connections. Upgrading to this technology usually requires specific venting and plumbing modifications that impact the total price. We ensure the system is properly sized for your family’s water usage. Exact pricing confirmed free on the call.

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 Glendale

How long do hot water heaters typically last?

In Glendale homes, traditional tank water heaters typically last between 8 to 12 years. Tankless water heaters, which offer energy efficiency, can often provide reliable service for 15 to 20 years with proper maintenance. The dry climate here can sometimes extend the life of these units.

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 option for Glendale residents. They heat water on demand, which means they only use energy when hot water is actually being used, unlike traditional tank models that continuously keep water heated. This can result in lower utility bills.

What are signs I need a new water heater?

Signs you might need a new water heater in Glendale include a lack of hot water, discolored or rusty water, unusual noises like rumbling or popping, and visible leaks from the tank.

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

Sediment buildup is a common issue for water heaters in the Glendale area, which can reduce efficiency and cause noise. Other frequent problems include issues with the thermostat, heating elements, or the anode rod, all of which can affect the unit's performance and hot water availability.

Is it worth it to repair a water heater?

Repairing a water heater in Glendale is often a good choice for newer units with minor issues, such as a faulty thermostat or a small leak. However, if your water heater is nearing the end of its typical lifespan or requires extensive repairs, replacement might be a more cost-effective and energy-efficient solution.
