In Boise, the water runs about 113 mg/L (6.6 grains per gallon) — moderately hard. That is the first thing to know about a tankless unit here, because scale is the slow problem behind most lukewarm-water calls. A heat exchanger that has never been flushed will lose temperature a little at a time, until one morning the shower runs lukewarm and an error code shows up on the display.
Call (877) 418-1589 and describe what the unit is doing — the symptom, the code on the display if there is one, and the brand if you know it. That is enough to send the right provider. There is no contact form on this site; the phone call is how the job starts.
Why tankless units fail in Boise
Boise draws much of its water from groundwater wells, which is why the mineral load is steady year-round. In the North End and the older Bench neighborhoods, original copper and galvanized runs are common, so a tankless repair visit here often starts with a look at water flow and pressure before anyone touches the unit.
Boise sits in a high-desert valley: cold winters with lows regularly below freezing from December through February, and hot, dry summers. Cold incoming water in winter makes a struggling tankless unit work harder, and exterior or garage-mounted units need freeze protection.

What affects the cost of a repair in Boise
The part is the biggest factor — a sensor costs less than a control board, and a control board costs less than a heat exchanger. The brand matters, because parts for some brands are easier to get than others. Scale matters in Boise more than most places, because a unit that has never been flushed may need a descale as well as the repair. And access matters — a unit in a tight closet or on a high exterior wall takes longer to work on than one in an open garage. This site does not publish prices; the price is set once the unit has been seen.
Questions people ask in Boise
How often should a tankless water heater be flushed in Boise?
In Boise, the water runs about 113 mg/L (6.6 grains per gallon) — moderately hard. At that level, once a year is the usual rhythm for a flush. A unit that goes two years without one will usually show it as lukewarm water or an over-temperature code.
Can a tankless water heater freeze in Boise?
Boise sits in a high-desert valley: cold winters with lows regularly below freezing from December through February, and hot, dry summers. Cold incoming water in winter makes a struggling tankless unit work harder, and exterior or garage-mounted units need freeze protection. A unit in a garage or on an exterior wall needs its freeze protection working before the first cold night of the season.
