Tankless repair and maintenance
Hot water on demand, for as long as the unit is looked after.
A tankless water heater, also known as an instantaneous water heater, heats water on demand. According to Energy.gov, tankless systems are 24 to 34% more energy-efficient than traditional tank water heaters while providing a continuous supply of hot water when properly maintained.
Routine maintenance reduces scale buildup, improves efficiency and extends the life of the system. Hard water accelerates mineral buildup inside a tankless unit, and a whole-home water softener helps reduce scale. Because many manufacturers have specific maintenance requirements, skipping routine service can affect warranty coverage.
Our plumbers service and repair Navien, Rheem and Rinnai tankless water heaters.
If yours is already installed
Back to full efficiency as quickly as we can.
Water use and energy costs climb when a tankless system is not running at capacity. We offer inspections, part replacement, system upgrades and emergency repairs, and our team is trained to pinpoint tankless faults specifically.
From power problems to water pressure issues, plenty of things can make a tankless unit misbehave, and the diagnosis is rarely the obvious one.
Navien specialists
Error codes, descaling and the venting nobody checks.
Navien tankless water heaters are high-efficiency systems, and because they are more advanced than a traditional water heater, correct installation, venting and maintenance matter more for long-term reliability.
We understand Navien error codes and diagnostics, perform proper descaling, and identify venting or installation issues that other plumbers overlook. Tankless systems need specific experience to keep performing over time.
Bertin Jaimes and his assistant Kevin did an excellent job of changing out our two 40 gallon water heaters to a tankless heater! They were very thorough and did a very neat job of plumbing in the new system and cleaned up the work site before leaving. Great job!!! See before and after pictures.

Common questions
Maintenance, descaling and hard water.
How Often Should a Tankless Water Heater be Serviced?
Tankless water heaters should typically be serviced once a year to help maintain efficiency and reduce mineral buildup inside the system. Homes with hard water, which is common throughout Central Texas and the Texas Hill Country, may require more frequent maintenance and descaling.
What is Descaling and Why is it Important?
Descaling is the process of removing mineral buildup from inside a tankless water heater. Over time, hard water minerals can collect inside the heat exchanger and reduce efficiency, restrict water flow, and shorten the lifespan of the system. Regular descaling helps keep your tankless water heater operating properly.
Do Tankless Water Heaters Require Maintenance?
Yes. Tankless water heaters require routine maintenance, including flushing, descaling, filter cleaning, and system inspections to help maintain performance and efficiency. Regular maintenance can also help identify issues before they lead to larger repairs.
Can Hard Water Damage a Tankless Water Heater?
Yes. Hard water can create scale buildup inside the heat exchanger and other components of a tankless water heater. This buildup can reduce efficiency, affect performance, and increase wear on the system over time. Installing a professionally selected water softener system can help reduce mineral buildup and improve long-term system performance.
