Common Tankless Water Heater Problems in New Orleans Homes
Warning signs that your unit may need repair or replacement
Tankless water heater problems often start small before they become major disruptions.

In some cases, mineral buildup, ignition failure, venting issues, or worn components can keep the unit from working properly. If your tankless water heater is acting up, it is better to address it early before you are left without reliable hot water.

Sandra TassinTrustindex verifies that the original source of the review is Google. On Sunday, 03/01/2026, Joshua with Serrano’s Plumbing came to my home in LaPlace, LA, to check my hot water heater which was not heating the water. He quickly diagnosed the problem and informed me that the thermostat on the hot water heater had stopped working. Due to the age of the hot water heater, Joshua recommended that it be replaced because it would cost just as much to repair it. Several options and price points were offered and I chose to let Serrano’s Plumbing install a new hot water heater. Joshua came back on Monday and had the new hot water heater installed and operating in no time. Serrano’s Plumbing is very professional and does quality work and I will call on them for any future plumbing issues that I may have.

So he gave me some solutions to get the things that he found taken care of and to get my water quality back up to the way it was when I first bought this house 25 years ago. The installation went smoothly and he was clean and after he left, it was like he was never here!
