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.

Tuck & Howell~5🌟🌟🌟🌟🌟 Jay is true to his word~5🌟 His team is the same, very polite and consistent~5🌟 Tuck & Howell-Trust Worthy ~5🌟🌟🌟🌟🌟 If you need reliable and trustworthy service, call Tuck & Howell! You won't be disappointed! Thanks again for assisting me with my HVAC issues!!! I was introduced to this HVAC company by a client and friend, and I’m so glad I was. The owner personally called me and arranged for a technician to come out that same afternoon, which I truly appreciated. Although I wasn’t a fit for the original offer, Jay still took the time to look over my system to see if it was repairable. True to his word, he arrived on time, was very attentive, and allowed me to fully explain what was going on. He clearly explained the problem, the solution, and the maintenance needed—step by step—without ever talking over me. Jay was personable, reliable, and refreshingly honest. There was no high-pressure sales pitch at all, which says a lot about his integrity. I’m incredibly grateful for the service I received and fully plan to do future business with Jay – Tuck and Howell. Highly recommend!
