Annual descaling with a descaling pump and flush kit keeps scale buildup from choking your heat exchanger. We pull and clean the water filter, check the thermostatic mixing valve, and test the gas valve and burner assembly so you avoid mid-winter short cycling and error codes.
View serviceWhen repair costs climb past the value of the unit, we quote a straight replacement. We match the new heater to your existing gas supply and venting, reuse what is safe, and haul the old unit away. Most swaps are finished in a single day with hot water back by evening.

Plenty of outfits will sell you a new heater when a $12 thermistor would fix it. We diagnose first, explain what failed, and give you a flat price before any wrench turns. That is the whole pitch.
Most calls placed before noon get a technician the same day. We carry a multimeter, manometer, gas leak detector, and water pressure gauge on every truck, so we can confirm ignition failure, gas supply issues, or a bad flow sensor on the first visit instead of ordering parts and rescheduling.
We are a state-licensed plumbing contractor, fully insured and bonded. Gas work follows local plumbing permit rules, and our techs hold manufacturer certification on Rinnai and Navien systems. We follow OSHA safety on every job and pull permits when the scope requires it.
Frozen pipes at 2 a.m. or a water leak before a holiday do not wait for business hours. Our emergency tankless water heater repair line stays open around the clock, and we prioritize no-hot-water calls so you are not stuck cold for days waiting on a callback.
Tell us the brand, the error code if you have one, and what the unit is doing. We schedule a same-day window or dispatch emergency service if you are without hot water.
We test gas pressure with a manometer, check voltage with a multimeter, and inspect the heat exchanger for scale. You get a plain-English explanation of what failed and why.
You approve the repair price before we start. If the fix is not worth it, we tell you and quote a replacement instead. No pressure either way.
We replace the failed part, reseal fittings, and run the unit through a full heat cycle. You see hot water at the tap and a clean, dry floor before we leave.
Four steps, no mystery. You call, we diagnose, we quote, we fix. You know the price before we touch a fitting, and you get a test run before we pack up.
Tankless units fail in predictable ways, and Prescott water makes some of them worse. Here are the calls we run most and how we handle them.
This usually points to a failed igniter, a stuck gas valve, or a flow sensor that has drifted out of spec. We test each component in sequence, replace the bad part, and verify the burner lights and holds a steady flame through a full draw cycle.
Codes like 11, 12, or 16 on Rinnai and Navien units point to ignition, flame failure, or vent blockage. We pull the code history, inspect the vent kit and intake for obstruction, and clear the fault at the source instead of resetting the board and hoping.
Hard water leaves mineral scale on the heat exchanger, which drops flow and causes temperature swings. We run a full descaling with a pump and flush kit, clean the water filter, and set you on an annual flush schedule so it does not come back.
Frozen condensate lines and cracked fittings are common after a hard freeze. We thaw the line, pressure-test the unit, replace any split O-rings or gaskets, and insulate exposed piping so the next cold night does not repeat the problem.
We cover the whole Prescott area, from the older homes and tight crawlspaces of Downtown Prescott to the newer builds in Prescott Lakes and the rural properties out toward Williamson Valley. If you are in Yavapai County and your tankless unit is acting up, we can get to you. Call and we will confirm the nearest available window.

Most repairs run $285-$650 depending on the part and the brand. A diagnostic and tune starts at $129-$199, and we waive that fee when you approve the repair. Deep descaling and heat exchanger service runs $450-$900. You get a flat quote before we start, so the number does not move.
The one that diagnoses before it sells. We are a state-licensed plumbing contractor, insured and bonded, working on Rinnai, Navien, Rheem, Bosch, Noritz, Takagi, AO Smith, and Bradford White units since 2025. We carry common parts on the truck and give you a flat price before any work begins.
Yes. Our emergency line runs 24/7 for no-hot-water calls, active leaks, and frozen lines. We prioritize homes without hot water and dispatch the nearest available technician. Most emergency calls in the Prescott area get a same-day window, including nights and weekends.
Ask three things: are they licensed and insured, do they carry a multimeter and manometer to actually test components, and will they quote a flat price before starting. A pro who pulls manufacturer certification on your brand and follows local plumbing permit rules will not guess at your repair.
Usually, yes. A $300-$650 repair on a unit with years left beats a $2,500-$4,000 replacement. It stops being worth it when the heat exchanger is cracked, parts are discontinued, or you have had three failures in a year. We tell you which side of that line you are on.
