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

Navien units are sophisticated systems that require specialized knowledge to troubleshoot. If your unit displays an error code, has reduced flow, or fails to ignite, a technician should inspect the heat exchanger and sensors. You typically need this service when the water temperature fluctuates or the unit stops responding entirely. Proper maintenance ensures these high-efficiency systems continue running as intended. Exact pricing confirmed free on the call.

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 Mobile

How long do hot water heaters typically last?

Navien tankless water heaters generally boast a longer lifespan than traditional tank models, often reaching 20 years or more with proper maintenance. This longevity is influenced by factors like water hardness and regular professional inspections, crucial in areas like Mobile. The pros can assess your unit's condition and advise on its expected remaining service life.

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

Navien tankless water heaters are highly efficient because they heat water on demand, eliminating standby energy losses. This means you only use energy when hot water is needed, a significant advantage for residents in Mobile. The specialists can confirm if your current unit is operating at its maximum efficiency.

What are signs I need a new water heater?

Common warning signs include inconsistent hot water temperatures, unusual noises like knocking or whining, or visible leaks. If your Navien unit is exhibiting these symptoms, it's advisable to have it inspected. Discolored water is another indicator of potential problems. Addressing issues promptly can prevent major inconveniences in your home.

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

Mineral buildup is a frequent issue for all water heaters, including Navien tankless models, particularly in areas with hard water. Other common problems can involve ignition system malfunctions or thermostat issues. The experienced pros can diagnose and fix these typical problems efficiently, restoring your hot water.

Is it worth it to repair a hot water heater?

Repairing a water heater is usually a good option for newer units with minor issues. However, if your Navien unit is older and requires significant or costly repairs, investing in a new, more energy-efficient model might be a better long-term financial choice. The specialist can offer a professional assessment of your unit's repairability.
