Although it’s one of your most important plumbing fixtures, you probably don’t think about your water heater until something goes wrong with it. Don’t panic if you have a faulty system that can’t meet your hot water needs. Contact Mullen Plumbing, Heating, and Cooling for water heater services, including accurate repairs and prompt replacements. 

Our licensed plumbers work with conventional water heaters as well as tankless units. We can easily diagnose a problem affecting your system and determine the best course of action. Trust our team with your water heater and discover how our services will enhance your plumbing system. 

Signs You Need an Emergency Water Heater Service

You’ll immediately notice when something isn’t right with your water heater. Some of the telltale signs that you need professional water heater services include:

  • Extreme temperature fluctuations
  • Discolored water
  • Hearing strange noises from the tank
  • Water leaking around the unit
  • Lack of hot water

Our plumbing specialists can pinpoint what’s causing the issue and recommend a repair or replacement service. Some problems, like discoloration or popping noises due to sediment inside the tank, require a simple fix like flushing the tank. Others, like a tank leak, are more extensive and leave you with no choice but to replace the system. 

No matter what problem affects your water heater, we’ll keep your best interests in mind and only recommend necessary services. 

Repairing vs. Replacing Your Water Heater: Which Is Better?

Figuring out the water heater services you’ll need depends on a few key factors. Many homeowners want to know if it’s better to pay for repairs or opt for a brand-new system when their hot water heater starts acting up. A thorough inspection will let us know whether you need repairs or if replacement is the better option. 

In general, we recommend replacing your water heater if it’s nearing the end of its lifespan. For conventional tank systems, this typically refers to a unit that’s at least 10 years old.

It’s also worth considering the cost of repairs versus replacement and how frequently your system malfunctions. Frequent repairs can quickly turn costly so replacing your water heater might be a better long-term investment.

Consider Tankless Water Heater Installation

When the time comes for water heater replacement, we’re the right team for the job. We specialize in tankless water heater services and can equip your home with this modern plumbing fixture. Installing a tankless water heater comes with many benefits, including:

  • Energy savings: Rather than keeping a large tank at a consistent temperature, these systems heat water on demand and will only use fuel or electricity when you need water. 
  • Longer lifespan: Tankless water heaters can last up to 20 years and prove to be a worthwhile long-term investment. 
  • Compact design: Without a bulky water heater tank inside your home, you’ll have more room for storage and moving around. 
  • Reduced maintenance requirements: You might need frequent electric or gas water heater repair services if you fail to maintain the conventional tank system. A tankless unit, however, is easier to maintain and can save you on repair costs. 

Our experts will review key factors that you should consider before installing a tankless water heater, including the upfront cost, available power sources, and your ideal system size. We perform quick installation services to accommodate your schedule and promise to supply your home with consistent hot water. 

The Benefits of Regular Water Heater Maintenance

When you call Mullen Plumbing, Heating, and Cooling for water heater services, our initial inspection will quickly let us know if your system needs basic maintenance. Many homeowners notice discolored water coming from their faucets or hear loud noises from inside the tank. This often stems from sediment buildup inside the tank due to a lack of maintenance. 

Our licensed plumbers fix these issues by draining the tank to flush out all of the sediment and debris inside. Flushing the tank once a year will keep the unit in good condition and help you avoid the need for urgent repairs.

Water Heaters FAQs

What are the signs my water heater needs repair or replacement?

Customer: “What are some signs that my water heater might need repair or replacement?”

Mullen Tech: “That’s a great question! Some common red flags are if you’re getting inconsistent water temperatures, like it’s hot one minute and cold the next. Also, if you hear strange noises like banging or rumbling, see any leaks around the tank, or notice your hot water running out faster than usual, it might be time to look at repairs—or even a replacement, depending on the issue. Give us a call or schedule service today, so that we can investigate any issues you are having and identify next steps”

What are the best energy-efficient water heater options for my home?

Customer: “I’ve been thinking about upgrading to something more efficient. What are the best options for energy-efficient water heaters?”

Mullen Tech: “Good thinking! Energy efficiency can save you a lot over time. Tankless water heaters are a popular choice because they heat water on demand, so you’re not wasting energy keeping a tank full all day. Heat pump water heaters are also great—super efficient and environmentally friendly. If you prefer to stick with a traditional tank, there are high-efficiency models that work much better than older units. I’d be happy to go over the pros and cons based on your household’s needs over a quick call.”

How much does it cost to repair or replace a water heater in South Charleston, WV?

Customer: “How much does it usually cost to repair or replace a water heater?”

Mullen Tech: “It really depends on the problem. Simple repairs, like replacing a heating element, are usually pretty affordable. But if the unit is older or has major issues, a replacement might be the better long-term solution. Here in South Charleston and the surrounding areas, the costs vary, but If you schedule service with us today, we can walk you through some options and even check if you qualify for rebates or financing to make it easier on the budget.”
