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.

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 Santa Ana

How long do hot water heaters typically last?

Traditional tank water heaters usually last between 10 to 15 years. Tankless water heaters, however, are designed for greater longevity, often reaching 20 years or more with proper maintenance. If your current unit is nearing the end of its lifespan, it's a good time to explore newer options. The pros can help you decide what's best for your Santa Ana home.

What is the most efficient type of water heater?

What are signs I need a new water heater?

You might need a new water heater if you're seeing leaks, noticing rusty or discolored hot water, or experiencing a sudden drop in hot water supply. If your water heater is making unusual noises like banging or popping, it's another strong indicator that it's time for an inspection. Proactive replacement can prevent significant issues in Santa Ana.

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

Sediment buildup is a frequent issue with tank water heaters, which can lead to noise and reduced efficiency. Tankless units can sometimes experience problems with mineral deposits in their heat exchangers. In both cases, a lack of regular maintenance can contribute to these issues. The pros are skilled at diagnosing and resolving these common problems.

Is it worth it to repair a water heater?

Repairing a water heater can be a good option if the unit is relatively new and the repair is minor and cost-effective. However, if your water heater is older and has required multiple repairs, investing in a new, more efficient model might be the better long-term financial decision. The pros can provide an expert opinion for your Santa Ana home.
