Emergency Tankless Replacement in Jeffersonville, IN
A tankless heater that leaks from the heat exchanger or refuses to ignite can leave you with no hot water at all. We offer same-day emergency replacement for common models and can often get a unit installed the day you call. If your exact model is not in stock, we can sometimes do a temporary repair to restore hot water while the replacement ships. We shut off gas and water to stop any leak on arrival. Call (317) 704-4250 anytime your tankless quits.

Condensing Tankless Replacement in Jeffersonville
Condensing tankless units like the Navien NPE series or Rinnai Sensei reach efficiencies above 90 percent by recovering heat from exhaust gases. They vent through inexpensive PVC and produce acidic condensate that must be neutralized and drained properly. We install a neutralizer cartridge and route the condensate line to an approved drain. Indiana has cold winters and humid summers, and that range puts steady seasonal stress on pipes, water heaters, and sump pumps. Condensing units still save gas because they work year-round on showers, laundry and dishes. We explain the cost difference so you can decide if the efficiency gain is worth it.
Tank to Tankless Conversions in Jeffersonville, IN
Converting from a 40 or 50 gallon tank to tankless frees up floor space and ends standby heat loss in a garage or closet. The catch is that tankless units often need a larger gas line, often three quarter inch or bigger, plus new venting. We evaluate your meter size and pipe run before quoting so there are no surprises mid-job. We also cap or reroute the old flue and seal the roof penetration if it is no longer used. Plan for a conversion to take a full day.

Recirculation Tankless Upgrades in Jeffersonville, IN
If you are tired of running the tap while you wait for hot water, a tankless with a built-in recirculation pump can bring heat to the fixture in seconds. Navien A series and Rinnai units with internal pumps can use a dedicated return line or a crossover valve under the farthest sink. We program schedules so the pump runs only during your morning and evening peaks. That keeps gas use reasonable while saving thousands of gallons of wasted water a year. This upgrade is a favorite in long single-story ranch homes.
