Professional tankless water heater maintenance helps address these issues before they lead to bigger performance problems. 

If you have noticed inconsistent water temperatures, reduced hot water flow, unusual system behavior, or it’s simply been a while since your last service, it may be time to schedule tankless hot water heater maintenance.

Couldn't be more pleased with the experience. I had a hot water heater emergency and they came when they said, quoted a fair market price, and resolved/replaced the tank in the span of a few hours. The employee was friendly, knowledgeable, and professional. Would use them again and would highly recommend.

I had a pretty emergent issue at the house I just purchased in Point. I called them during the evening of 2/23 and by 10am on 2/24 they had someone over at my house. By the end of the day on 2/25 my issue was resolved. I had a piece of broken PVC pipe stuck at the end of my service line from a bad job done by the plumbers who altered the plumbing back around the hurricane Sandy renovation project. It was causing a backup into my home. They were able to fix this without us having to dig under the road. This helped avoid getting the township involved. Jeff and the boys were a pleasure to work with. I’d highly recommend their services. Nothing felt pushed on me and I got constant updates during the job. Stay away from larger corporate companies and hire an honest business like this one.

Tankless Water Heater Maintenance FAQs

Most manufacturers recommend professional maintenance about once a year. Regular flushing helps remove mineral buildup that can reduce efficiency and shorten the life of the system.

A tankless water heater maintenance service may include inspecting the system, checking for mineral or scale buildup, flushing the unit when appropriate, cleaning accessible filters or components, and testing performance. Our technicians can also identify signs of wear or problems that may need repair.

It may be time for service if you notice inconsistent water temperatures, reduced hot water flow, unusual operation, or other changes in performance. You should also consider maintenance if the system has not been professionally inspected or serviced according to its recommended schedule.

Tankless systems can develop mineral deposits as water moves through the equipment. Flushing may be recommended to remove buildup and support proper operation. How often your specific unit should be flushed can depend on the manufacturer, water quality, and system use.

If our technician identifies a problem during maintenance, we can explain the issue and recommend the appropriate next step. Depending on the condition of the equipment, that could mean a repair, replacement, or electric tankless water heater installation options.
