Tankless Water Heater Repair in Atlanta, Marietta, & Alpharetta, GA

Energy-efficient and reliable, tankless water heaters are an increasingly popular appliance for homeowners in Georgia. While solid and sturdy, they’re not indestructible; over time, components may falter and fail.

When your tankless water heater stops producing the hot water you require, the team at United Air Temp can repair the system and restore it to operational condition.

Contact United Air Temp to schedule fast and effective tankless water heater repairs in Atlanta, GA.

How Tankless Water Heaters Operate

Tankless water heaters use either an electric element or a gas burner to warm cool water flowing through the pipes and into the unit. It’s a simple, efficient, and highly effective method of heating a virtually endless hot water supply.

Most importantly, since there is no storage tank, the amount of energy used heating the water and the energy saved not storing the water reduces your utility usage significantly.

Do you have more questions about the operation and benefits of tankless water heaters?

4 Common Causes of Tankless Water Heater Failure

Some of the most common causes of water heater failures requiring repairs include:

  • Overloading. When you exceed the flow rate capacity, overloading can occur. Frequent overloading often indicates your system has an insufficient capacity for your needs.
  • Sediment buildup. Sediment that builds up in the pipes can diminish water flow and cause rust in your pipes.
  • Ignition failure. When there is a blockage in the fuel supply, electrical wiring comes loose, or ventilation is blocked, ignition failure may occur.
  • Component failure. Problems with circuit breakers, electrodes, gas valves, or other components can cause a tankless water heater to fail.

Frequently Asked Questions About Tankless Water Heater Repairs

Properly maintained tankless systems can provide reliable operation for 20 years or longer.

If repairs are impractical or not possible due to system age or another factor, we can replace the unit. Tankless hot water replacement typically takes two to three hours to complete.

We strongly advise against DIY repairs. Tankless systems require specialized tools and training to service, and any DIY repairs may void warranty coverage or homeowners insurance coverage.

What Our Clients Are Saying
testimonial_image The tech was at my home less than 10 minutes and gone within 20 minutes due to having my A/C up and running. I really appreciate his response to my home and working with my son due to me being out of town, but we spoke on the phone.
testimonial_image The technician arrived promptly, wore a mask, was very courteous and professional. I am generally very satisfied with service by United Air Temp. In addition to good service (they repair well), it is easy to speak to a person, and promptly. Thank you.
testimonial_image Great service! I called because I was under the impression the AC was not working upstairs. Someone came on the same day, checked out the system, and ensured everything was working. He was polite, thorough, and friendly.
testimonial_image Tech was very attentive and professional. He went out his way to explain everything to me as he was doing it. I appreciated him keeping me informed.
testimonial_image The service technician was awesome! He spent the extra time necessary to ensure the leak in our system was fixed, the system fully recharged and everything was functioning as it should. He was extremely thorough and very professional. We are extremely pleased with the result!
