Whether the fix is a single part or a full unit replacement, our crew is ready with same-day appointments and advanced tools.
Before quoting, we find out why the unit failed: a bad thermostat, a failed heating element, a worn gas valve, a depleted anode rod, or a tank at the end of its life. That diagnosis tells us whether repair or replacement is the smarter choice.
Many failures are fixable and do not require full replacement. We repair thermostats, heating elements, gas valves, thermocouples, pilot assemblies, and leaking valves, restoring hot water without the cost of a new unit when the tank is still sound.
When the tank is corroded or leaking, no repair can save it. We remove the old unit and install a correctly sized replacement, matching the capacity to your household so you are not left short on hot water or paying to heat more than you use.
The two quiet killers of a water heater are sediment and a spent anode rod. We flush the tank and replace the anode rod, which are among the most cost-effective ways to extend the life of your unit.
A leaking tank can cause water damage quickly. We respond fast, determine whether the leak is from a repairable fitting or the tank itself, and provide a clear path forward before the problem spreads.
The cheapest repair is the one you prevent. Herndon McFarland Plumbing offers maintenance that reduces sediment and catches wear early, protecting efficiency and lifespan.
If your water heater failed sooner than expected, the water flowing into it is a major reason. Hard water contains dissolved calcium and magnesium. In a heated tank, those minerals precipitate and settle to the bottom as sediment. This forces the unit to run longer and hotter to heat through the insulating layer, which homeowners hear as popping and rumbling.
Scale and sediment are not good for your water heater. The U.S. Environmental Protection Agency identifies scale and sediment buildup as drivers of both reduced efficiency and shortened equipment life. A tank water heater in a hard-water home truly does not last as long as the same unit in a soft-water home.
The anode rod is the second casualty. That sacrificial rod is designed to corrode in place of the steel tank, but hard water and heavy use consume it faster, and once it is gone, the tank itself begins to rust from the inside. Most homeowners never know the rod exists until the tank is already failing.
That is why at Herndon McFarland Plumbing, we treat the water, not just the symptom. We flush sediment, check and replace the anode rod, and when a tank has already lost the fight, we size a replacement built to handle Farmers Branch water. A water softener is often the longer-term answer.
Mary Beth turned to us twice, once for an urgent plumbing problem and once to replace her water heater. A homeowner does not bring the same company back for a job as significant as a water heater unless the first experience earned it.
She noted:
“I used this company once for a plumbing emergency, and once to replace my water heater. I am so happy with their skill, and the people I’ve spoken with have always been very nice. This is my go-to plumber, and I’d definitely recommend them.”
Becoming a homeowner’s go-to plumber, trusted for both emergencies and water heater replacements, is exactly the standard we hold to on every visit. Read Mary’s full Google review.
Tylor Kopas had already been through five plumbers who either could not solve the problem or quoted enormous sums with no guarantees. Calling after 5 pm on a Friday, he expected voicemail. The fact that we answered and moved fast turned a frustrating search into a solved problem.
He shared:
“We called Herndon McFarland on a Friday after 5 pm and expected to leave a message, but Lee answered and was incredibly helpful. He made sure they were out to our house first thing Monday morning and fixed our issue within an hour. The total price was less than a quarter of what the other companies quoted us, and we’ve never been more impressed with a plumber before. We will only use Herndon McFarland moving forward!”
Answering the phone, showing up fast, and fixing the problem at a fair price is the difference we aim to be for Farmers Branch homeowners. Read Tylor’s full Google review.

Watch for rusty or discolored hot water, popping or rumbling noises, water pooling around the base, or a unit that no longer keeps up with your household. Minor issues, such as a faulty thermostat or element, are usually worth repairing. A leaking tank or a unit older than 10 years often calls for replacement. We diagnose the cause and tell you what makes sense for your situation.
We inspect the unit to find the actual failure point, whether the thermostat, heating element, gas valve, anode rod, or the tank itself. We check for leaks, sediment, and corrosion. Then we explain what we found and give you upfront pricing for the repair and, if relevant, the replacement, so you can weigh the two options.
A tankless unit heats water on demand, saves space, and often lasts longer because it does not store heated water. It can be a strong choice when replacing anyway, though it depends on your hot water demand and gas supply. We walk you through the tradeoffs plainly rather than pushing one option.
If the tank is sound and the failure is a repairable part, repair is usually the smarter choice, restoring hot water for a fraction of the cost of a new unit. Once repairs approach half the cost of replacement, or the tank is old and corroding, replacement protects you from repeat failures. We give you the numbers so the choice is clear.
Farmers Branch hard water leaves calcium and magnesium sediment in the tank and consumes the anode rod faster. That is why a tank here can wear out sooner, and why sediment flushing and anode service matter more in this area.
You can book online anytime, and we will schedule a visit. We offer same-day appointments when you are without hot water and round-the-clock service for leaks and emergencies across Farmers Branch and the DFW metroplex.
From slab leaks under the foundation to sewer line repipes, every job is diagnosed, documented, and done right. A look at recent work across North Dallas.
Excellent customer service, very friendly staff from the person taking the call to the staff fixing the repairs. Very trustworthy company. Shaun explained the step-by-step process and provided very fair prices.
Their positive, upbeat, anxious-to-please attitude made the whole process the very best it could be! All of the employees were a pleasure to work with. I highly recommend Herndon McFarland.
Trent and Reggie were the most professional associates entering our home. They treated our home with respect as if it were theirs. We will use this company again because of them and our experience.
