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 Chicago

How long do hot water heaters typically last in Chicago?

In Chicago's climate, tank-style water heaters typically last between 8 to 12 years. Tankless water heaters, with proper maintenance, can often last 20 years or more. The hard water sometimes found in the Chicago area can affect longevity, so regular checks are beneficial.

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

What is the most efficient type of water heater for a Chicago home?

For many Chicago homes, tankless water heaters are a highly efficient choice, heating water on demand and reducing standby energy losses. Heat pump water heaters are also an excellent energy-saving option, particularly in basements where temperatures are more stable. These can significantly reduce your utility bills.

What are signs I need a new water heater in my Chicago house?

Common signs that your Chicago water heater needs replacing include a lack of hot water, discolored or smelly hot water, leaks around the base of the unit, or loud noises like popping or hissing. If your unit is over 10-12 years old, it's a good time to consider an upgrade.

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

Sediment buildup is a frequent issue in Chicago water heaters, which can lead to reduced efficiency and strange noises. Another common problem is a malfunctioning thermostat or heating element, resulting in insufficient hot water. Leaks from the tank itself are also a serious concern that requires immediate attention.

Is it worth it to repair a water heater in Chicago?

Repairing a water heater in Chicago is often worthwhile if the problem is minor and the unit is still in good condition. However, if the tank is leaking or showing signs of significant corrosion, it's usually more cost-effective to invest in a new, energy-efficient water heater for your Chicago home rather than facing repeated repairs.
