A tankless heater has to be sized by flow, not by gallons stored. We look at how many fixtures your household runs at the same time, the incoming water temperature, and the layout of the home, then recommend a unit or combination of units that can meet that demand. We also check whether the gas line, venting, and electrical supply can support it, because many tankless conversions require upgrades that a tank never needed. You get those details in the quote, so the price you approve covers the whole job.
For repairs, our plumber reads the unit's error history, checks the flow sensor, igniter, heat exchanger, filters, and venting, and confirms gas pressure or electrical supply. Many problems trace back to scale or a clogged inlet filter, which a thorough cleaning resolves. When a unit has a failing heat exchanger or is out of production with hard-to-find parts, we explain the situation honestly and put repair and replacement side by side so you can choose.
Local conditions are a big factor with tankless equipment. Central Texas water is hard, and the minerals in it build scale inside the heat exchanger, which cuts efficiency and triggers errors if the unit is not descaled on a regular schedule. Many homes in this area are larger houses built from the 1980s through the 2000s with several bathrooms, so peak demand can be high and sizing matters even more.
In a house where the main bedroom suite sits far from the utility area, we may suggest a second, smaller unit closer to those fixtures, or a recirculation setup, so hot water reaches the far end without a long wait. We explain the cost and benefit of each choice before you decide.

The plumber who handles your installation or repair stays your contact for maintenance and any later questions.
A well sized tankless system delivers hot water as long as you need it, whether that means a long shower after someone else just finished or running the dishwasher while the laundry fills. The unit only fires when a tap opens, so you are not paying to keep a tank of water hot around the clock. It takes up a fraction of the space of a tank, and with regular descaling, a tankless heater typically outlasts a conventional one.
Neglecting a tankless unit erodes those benefits. Scale buildup forces the burner to work harder, lowers output, and leads to error shutdowns at inconvenient moments. A clogged inlet filter reduces flow throughout the house. Left alone long enough, scale can damage the heat exchanger, which is the most expensive part of the unit to replace.
When the job is done, your plumber walks you through the controls, explains the error codes you are most likely to see, and recommends a descaling schedule suited to your water. If you are converting from a tank, we also explain what changes to expect, such as the brief wait for hot water at distant fixtures. Questions after the fact go to the same plumber who did the work.
Many homeowners ask whether tankless is worth the higher upfront cost. The honest answer depends on how much hot water your household uses, how long you plan to stay in the home, and what upgrades your gas or electrical service needs, and we will give you that comparison plainly.
