How Can We Help?

Professional tankless water heater repair services are important for your safety and the integrity of your equipment. There are several issues that can occur with a tankless water heater. Working with Tuck & Howell Plumbing, Heating & Air can ensure a fast diagnosis of a problem and a prompt fix.

Tankless Water Heater Repair Services

Tankless water heaters have fewer parts that require replacement in comparison to systems with tanks. There are still issues that can arise, though. For example, a tankless system usually has filters that remove minerals and sediment from your water. You will need to clean or replace this filter to prevent scale buildup and corrosion. If replacement doesn’t occur, this can lead to issues like low flow rate. Interior components may experience mineral deposits or corrosion that impede normal equipment function.

There are several signs that indicate a problem with your tankless water heater.

Lack of hot water
Change in water pressure
Noises coming from the unit
Discoloration of water

If there isn’t hot water coming from your faucets or fixtures, there may be an issue with an interior component. If your unit is experiencing issues with overheating, it will shut down to prevent system damage and safety concerns. Heating elements may have a buildup of minerals on them that is preventing water from heating up. Even though you don’t have a tank to worry about when it comes to hot water availability, there are different sizes of tankless heaters available. You may not have a large enough unit to meet your household demands.

Tankless heaters can run on different fuel sources, including gas and propane. If your system’s exhaust system isn’t functioning correctly, you may notice the smell of gas in your home. Other odd smells include the smell of something burning. Your unit may shut down to prevent indoor air quality issues. Odd smells coming from your tankless heater indicate there’s a problem, so call a professional for help immediately.

Always impressed! A technician who listened carefully to our concerns before tackling our problem!
Today, Jesse Seger was that Tuck & Howell technician.
We needed him to locate and replace a UVC Bulb in our Air Purification unit attached to the HVAC System. He completed a thorough inspection of our entire system, located and assessed our problem. Jesse spent time explaining his findings, he proposed a plan of action answering all questions in a very professional easily understood manor to both my wife and me. It was an easy decision to agree to sign the work order for repairs to be completed!
We are very happy customers! Jesse was great!

I have to say that I have never experienced such a high level of service from a company! Would ten out of ten recommend this company! My service technician was Chris Satterfield and he made an after hours trip to help me out! He was polite, diagnosed the plumbing issue and helped point me in the right direction to get the issue resolved with my sprinkler company! Thank you and would definitely give ten stars if ratings went that high!

Very impressed with everyone at Tuck & Howell. I initially called Waldrip. Their guy told me my HVAC reversing valve was bad and it would cost right at $7,000 to fix. Enter Tyler from Tuck & Howell and all it ended up being was a bad solenoid. Saved me almost $7,000! Got a customer for life now. Many thanks!!

This morning I called Tuck and Howell to make an emergency HVAC repair appointment. Despite all time slots on the 'book online' feature being filled, they were able to make room for me. Our technician, Owen B., arrived on time and he clearly knew what he was doing. He diagnosed our issues, gave us a few quotes, and then saved our lives by applying the necessary fixes to our outdoor AC unit. He also gave high level answers to all of our questions, which is a great indicator of his experience and knowledge. Tuck and Howell should hold Owen close, he did a stellar job.
HVAC repairs are quite expensive, but I feel with Tuck and Howell, I will not need repairs often. Shout out to our tech, Owen B. You're good at what you do, thank you!

Brandt Connor was the service technician that took care of my mothers AC unit. He went above and beyond for her. Excellent customer service and did a great job explaining what was the issue.

I couldn’t have been more satisfied with the service I received. They came within hours of my call. I was in a bind with a unit not working and a home showing scheduled for the next day. The technician, JD, was courteous, professional and within a short time was able to diagnose my multiple problems. The two items were also not only available but on his trunk. He immediately began repairing and replacing in the boiling temperature outside heat and with trips into my hot attic. While waiting to confirm the problems were fixed he checked and cleaned my other three units without being ask. His supervisor joined him and was just as kind and professional.
The charges were reasonable, especially since I wasn’t needing to replace an entire unit.
I would recommend them to anyone needing an AC repair.
