Tankless Water Heater Repair

Schedule Now

Many homeowners associate water heaters with high energy bills, hot water running out, and a massive unit that takes up space in your home. However, there is one thing that challenges these long-standing perceptions about water heaters—tankless water heaters.

Tankless units can produce endless hot water and are considered highly efficient. Unlike their traditional counterparts, they have no storage tank, so you can save on space. What's even more impressive? They have been proven to be 30 to 40% more cost-efficient.

Since tankless units only provide hot water on demand, you can also save time and energy. At Rooter Ranger, we have carried out countless repairs and installations in cities throughout Nevada, Arizona, and California. For dependable tankless water heater services, we are your best option!

Signs You Need Tankless Water Heater Repair Services

Tankless water heaters are considered a smart addition to any home. Unlike storage tank water heaters, tankless systems don't need to run regularly to supply you with heated water. Given that they are accurately sized and installed accordingly, you won't have to worry about running out of hot water. While tankless units are known for their efficiency, they can also require occasional repairs and maintenance. If you notice any of the following signs, give us a call right away.

Drastic change in water quality

If you notice that your water is rusty, cloudy, or filled with sediments, it's a clear indicator that something is wrong with your tankless water heater. Check with your municipal water supplier if the problem stems from a quality issue with the local water source. If there is no problem with the local water source, give us a call so we can check if your tankless unit is malfunctioning or breaking down.

Strange water taste or smell

Metallic and unusual water taste can be caused by iron in the water heater. Water with high levels of iron is not safe for consumption and should be checked by our skilled and experienced plumbers right away. Our water plumbers can accurately diagnose if the problem is with the water or your tankless unit.

Booming or banging sounds

Booming or banging coming from your tankless unit clearly indicates the presence of sediment in the system. In similar scenarios, our plumbers will flush the sediments out to resolve the problem.

Inconsistent water pressure/hot water

The point of having tankless units is so you won't have to wait for hot water. If there are noticeable inconsistencies, get in touch with us immediately. Poor water pressure and lack of hot water often point to a severe problem. In some cases, you might need to have the system replaced entirely.

Heater keeps shutting off

Most tankless water heaters come with safety devices that shut the system off when the system overheats. Overheating can be caused by a clogged whole-house filter connected to the system. You can change the water filters to see if the problem is fixed. If changing the filter won't fix the problem, it's time to bring in our trusted professionals.

Leaks or water pools

Any leaks from plumbing appliances are bad news. While tankless units experience less leaking than their conventional counterparts, leaks can still happen. Our expert professionals can check if the leak is caused by a broken or loose valve.

Benefits of a Tankless Water heater

As technology advances, so do our homes. A tankless water heater provides homeowners with a more efficient, cost-effective, and reliable heat source for our water. There are many benefits to installing a tankless unit in your home, including:

Adaptable Source

Unlike standard water heaters that constantly heat water, tankless units heat water on demand, saving energy and lowering your bills.

Small Size

Tankless heaters are much more compact than other styles and are hooked up to the wall, which takes up less space.

Long Lifespan

Tankless heaters generally have a longer lifespan than standard tank models. With proper maintenance, they can last up to 20 years or more, offering long-term value and reducing the need for frequent replacements.

Reduced Risk of Water Damage

Tankless heaters eliminate the risk of tank leaks or ruptures since they don't store water, minimizing the risk of water damage.

These guys especially Travis and his supervisor Seth are the very best. They were very relentlessly trying to help us and find a way to fix our plumbing problem. They were very compassionate with my family and our bad state we were in for over a week. Tried various Companies only to no avail. We are so grateful to these guys and the Rooter Ranger company. They were literally scratching their heads trying their hardest to figure out a way to get us to where we could use our toilets and showers again. We highly recommend this plumbing service over all others, hands down. 🙏🏿

Our Technician Carvel in Las Vegas gets a 10/10 rating by my family and I. He was very responsive and came to our home to replace our water heater. He was friendly, professional and very knowledgeable. I have used this company recently before and I am pleased with the great value and good quality of products they use. I have had great service from the time I call to request a repair till the time the technician completes it. Thank you again Carvel for providing great customer service to us and installing our new water heater.

Antonio just left who replaced our garbage disposal. We called yesterday for an emergency to unclog our disposal. Antonio showed up with such a friendly yet professional demeanor. We both were very comfortable with him. He answered all our questions and he gave us options which would work best. We decided to replace our garbage disposal. Antonio gave us a price which was reasonable with no hidden fees. He scheduled us for this morning. Antonio showed up ready to go and disposal in hand. He explained why he choose the one he got and how it works. Antonio got to work and was done in no time. Thank you Antonio! 🤙🏼

We had an emergency flooding from our toilet on a Sunday morning. We tried contacting various Plumbing companies but the majority never called back. Rooter Ranger sent out Antonio who was prompt, professional and extremely helpful along with being very informative. He discovered and corrected the problems at a Very Reasonable Cost. We are using their services for other plumbing difficulties. We Highly recommend Antonio & Rooter Rangers if you have any plumbing problems.

Alex was the perfect technician for the job! He diagnosed the issues I was having for my two bathrooms. He was able to clear my bathtub drain as well as the toilet. The supervisor also came by to check on the pipes and we got an estimate for a permanent solution to my houses drainage issue. 5 star worker and I will definitely recommend this plumbing company to friends and family!
