What affects the price

Replacing your water heater involves several variables that change the final bill. The biggest factor is the unit type—tankless models usually cost more upfront than traditional tank-style heaters due to installation complexity. You also have to consider the fuel source, as switching from gas to electric often requires electrical panel upgrades. Size matters too; a larger home needs a unit with higher recovery rates. Finally, local building codes might require additional safety equipment, like expansion tanks or updated venting.

Frequently asked in Garland

How long do hot water heaters typically last?

For a standard tank water heater, the typical lifespan is between 10 and 15 years. Factors like water quality in Garland and regular maintenance can influence this duration. If your unit is reaching this age, it's smart to start looking into replacement options.

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

The cost to install a new water heater can vary based on the type of unit and installation complexity. Tankless water heaters, for instance, usually have a higher upfront investment but can offer long-term energy savings. Call us for a personalized quote for your Garland home.

What is the most efficient type of water heater?

Tankless water heaters are generally considered the most efficient because they heat water only when it's needed, avoiding the energy waste of keeping a large tank hot. This can lead to noticeable reductions in your energy bills over time.

What are signs I need a new water heater?

Pay attention to signs like discolored or smelly water, unusual noises such as popping or rumbling, or leaks around the base of the unit. If you're experiencing a shortage of hot water more frequently, it's a strong indicator that a replacement might be needed.

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

Sediment buildup is a frequent issue that can reduce a water heater's efficiency and cause noise. Leaks, particularly from the tank itself or at pipe connections, are also common problems that require prompt attention to prevent further damage.

Is it worth it to repair a hot water heater?

Repairing a water heater is often a good idea for minor issues, like a faulty thermostat or a worn-out heating element. However, if the tank itself shows signs of corrosion or leaks, it might be more cost-effective to invest in a new unit for your Garland residence.
