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

An expansion tank protects your plumbing system from pressure spikes caused by thermal expansion as water heats up. We install this tank on the cold water supply line, which helps prevent leaks and extends the life of your heater. You need this installation if your home has a closed-loop plumbing system or if you experience relief valve dripping. 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 Montgomery

How long do hot water heaters typically last?

For Montgomery homes, a standard tank water heater generally lasts between 8 to 12 years. Regular maintenance, like flushing the tank to remove sediment, can help extend its lifespan. If your unit is approaching this age, it's wise to have a professional inspect it for potential issues.

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

What is the most efficient type of water heater?

Many Montgomery homeowners find high-efficiency tankless water heaters to be an excellent choice for energy savings. These units heat water on demand, so you're not constantly heating a large tank. Gas-powered tankless models are particularly effective for meeting high hot water demands.

What are signs I need a new water heater?

Common indicators in Montgomery homes include a decrease in hot water volume, strange noises like popping or hissing, rust-colored water, or leaks around the base of the unit. If your water heater is over a decade old and showing these symptoms, replacement is likely needed.

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

Sediment buildup at the bottom of the tank is a frequent culprit, leading to reduced efficiency and noise. Another common issue is a malfunctioning thermocouple or heating element, which can result in no hot water. These problems are best diagnosed and repaired by a professional.

Is it worth it to repair a hot water heater?

Repairing a water heater can be a good option for newer units or minor issues like a faulty thermostat or pilot light. However, if your Montgomery unit is old, has a leaking tank, or has required multiple repairs, investing in a new, more efficient model is usually the better long-term choice.
