When your tankless water heater starts showing signs of trouble, it’s easy to wonder (and worry about) whether it’s time for a full replacement. But here’s the good news: not every issue means the unit’s done for. Many common problems can be repaired quickly and affordably, especially if the system has been well-maintained. Replacement usually only makes sense when the system is facing serious internal damage, ongoing breakdowns, or the repair costs rival a new unit. At America’s Plumbing Company, we’re not here to sell you something you don’t need.
If a repair brings your system back to life, that’s the route we’ll take. If it’s time for a new tankless water heater installation, we’ll help you choose the right one for your home and walk you through your financing options if needed. No pressure, no sales pitch—just honest answers and expert service to help you move forward with confidence.
You likely chose a tankless water heater for the same reasons most people do—endless hot water, energy savings, and reliable performance. But when something goes wrong, it tends to show up fast—especially if maintenance has been skipped. We work with these systems every day and handle everything from minor hiccups to major malfunctions. Here are some of the most common tankless water heater repairs we take care of:
If you turn on the tap and get nothing but cold water, your burner may not be firing. This can be caused by dirty components, gas flow issues, or a faulty ignition system. We’ll diagnose it quickly, clean or replace the part, and get your hot water back.
When your system flashes a code, it’s trying to tell you something. These alerts can point to pressure problems, blocked vents, or sensor failures. We read the code, trace the issue, and make the right fix on the first visit.
Hot water that turns cold mid-shower or swings between hot and lukewarm? It’s often caused by scale buildup, a dirty heat exchanger, or sensor errors. We’ll flush the system, test components, and restore stable temperature control.
If water pressure from your hot taps has dropped, a clogged inlet filter or scale in the lines could be the problem. We’ll clean or replace the filter, flush out mineral buildup, and get your flow back to normal.
Noticed water pooling under or around your tankless unit? Leaks can come from internal components like valves and heat exchangers or external connections and fittings. We’ll inspect the entire system, identify the exact source, and make the necessary repairs to stop the leak for good.
We don’t just fix what’s obvious—we take the time to find out why it happened in the first place. That means no patch jobs, no quick cover-ups, and no leaving you with the same problem waiting to resurface.
Sure, most plumbers can work on water heaters—but that doesn’t mean they do it often, or do it well. Whether you’ve worked with us before or just found us today, we’re glad you’re here. At America’s Plumbing Company, we’ve been the local water heater company Sacramento trusts since 1999, handling everything from quick fixes to full installations with the kind of service that keeps people coming back.
