 Trustindex verifies that the original source of the review is Google. Even though we didn’t get great news, we got the news we expected. We do have a leak but the plumber that came to the house was very professional and friendly. Absolutely great customer service. My husband who is a Master Plumber showed near the end and so he knows more about what’s going on. Very happy with this service. Thank you Olshan for sending a competent plumbing company out for our free leak inspection. Thank you BillyGo for your services.

 Trustindex verifies that the original source of the review is Google. This review is for technician Cabot. He came to my house to give an estimate to locate the main water line to the house so I would know where not to plant a tree. Unfortunately, he was unable to do it based on the fact that the builders used PEX and did not run a tracer wire with the pipe. However, Cabot stuck around and gave me a "best guess" on the path the pipe took based on the location of the meter and the house inlet. He suggested places where the tree would be ok and where I should probably not plant it. Even though he could not tell me where the pipe was and I will still need to be careful, I do appreciate his time.

One thing he did mention was that if he had been able to do this, it would have typically been around $900. I do not claim to be an expert or know what is involved, but $900 to locate 15 feet of pipe would have been way out of my budget. For that price, I would have just dug the hole carefully and much bigger than needed to make sure I did not come across the pipe.

 Trustindex verifies that the original source of the review is Google. Gio and Juan were excellent and did an outstanding job installing a whole new HVAC system. Gio walked me through everything at the end and made sure to answer all my questions. Cleanup was great and left the property looking like it was before they arrived. Would recommend BillyGo to anyone for HVAC or plumbing needs.

Tankless Water Heater Repair in Dallas-Fort Worth, TX Frequently Asked Questions

It typically costs $150 to $800, though the average tends to be around $600 to fix a tankless water heater. Tankless water heaters require periodic flushing of minerals and sediment from building up inside the unit, and when this maintenance is neglected, you will likely run into issues with your water heater that will need to be repaired by a professional plumber.

While tankless water heaters require significantly less repairs than storage tank water heaters, they can still encounter problems that will require a professional’s skillset to repair them when those issues do arise.

Your tankless water heater could stop working for a plethora of reasons; a plugged heat exchanger due to hard water, a blocked vent and air intake, or running too many hot water appliances at once. Tankless water heaters only heat water as needed, so running multiple appliances that require hot water can overwhelm your water heater and cause it to stop working. If your tankless water heater does stop working, call billyGO to have an expert help resolve the problem.

Common issues with tankless water heaters range from air supply and exhausts getting blocked (which can cause the device to shut down), the pilot light failing to ignite, sensors quitting at random, and more. It’s important to have one of our certified technicians at billyGO to repair your tankless water heater as trying to do it yourself could potentially void the warranty or cause further damage.

Tankless water heaters do rely on gaskets, seals, and other components that can wear out over time. Generally, an annual maintenance service will include an inspection of these components and give the ability to have them replaced when they start to show signs of wear or failure. However, if you do find water leaking from your system, don’t be alarmed. Simply call a repair technician to come out and take a look at the issue and our team will quickly identify the issue and fix it for you.

Is your Tankless Water Heater shutting itself off? This is a problem! Power issues with your Tankless Water Issues are usually an indication of a clogged filter. Tankless Water Heaters create extremely hot exhaust, and if your unit is not properly ventilated for whatever reason, it will cause your system to break down and shut down.

Any time that your water supply is discolored and tinted with a brown, red, yellow, black hue and/or has a foul, metallic tasting smell to it, something is wrong. Since Tankless Water Heater units do not have a reservoir bank for sediment to form in, you shouldn’t have discolored or foul tasting water, so in the event that you do, call billyGO right away! One of our plumbing experts will examine your water heater and water supply to pinpoint the issue and provide repair solutions. It should be noted that water discoloration and foul-tasting water can be caused by many other things in your Dallas-Fort Worth, TX home, but if you notice it in conjunction with any of our other listed signs of a Tankless Water Heater in need of repair, it’s likely due to your water heater.

Your Tankless Water Heater system will likely make very faint noises in its normal operation, but if you notice any odd, loud noises such as banging, humming, screeching, or knocking, there is something wrong with your water heater! Make sure to call billyGO right away if you hear any loud and unfamiliar noises coming from your Tankless Water Heater to schedule an Expert Tankless Water Heater Repair as soon as you possibly can.

Tankless Water Heaters should never leak water, so if you are noticing water leaking from your unit, call billyGO immediately! It could be due to a loose valve or fitting, or something much more complex, but professional assistance from billyGO will be needed.
