Tankless Water Heater Repair and Service, Langley City and the Township
Households with a tankless water heater tend to forget what running out of hot water even feels like. The unit heats water the moment a tap opens, for as long as the tap stays open, so the third shower of the morning is as hot as the first. The trade-off only shows up on the rare day something goes wrong: there is no tank of stored hot water to coast on, so a fault means cold water now, not eventually. Eaton's Heating repairs tankless water heaters across Langley City and the Township, covering Navien, Rinnai, Takagi, Noritz, Bosch, and Rheem. The diagnostic is $189, most component repairs add $150 to $200 or more depending on the part, and every price is quoted and approved before the work starts.

Most tankless units in Langley got here one of two ways, and how they arrived tells you what tends to break. The first came through renovations, when homeowners in Walnut Grove, Brookswood, and Murrayville swapped an aging tank for an on-demand unit sometime in the last decade or so. Those systems have real hours on them now, and the wear shows up in the usual places: flame rods fouled by years of ignition cycles, flow sensors drifting out of calibration, ignition boards reaching the end of their run. The second is newer Willoughby and Latimer construction, where builders fitted tankless units from day one; those systems are younger, and when they act up, the cause sometimes traces back to the original install, a gas line sized tight or venting done to the minimum, rather than the unit itself. Tankless water heater repair starts with knowing which of the two a unit belongs to. And one common mix-up deserves a mention: if a single wall-hung unit heats both your house and your hot water, that is a combi boiler, a different appliance with different failure patterns, and it lives on our boiler repair page.
Underneath almost every tankless complaint, sooner or later, you find the same culprit: minerals in the water. Every litre that passes through the heat exchanger leaves a trace behind, and over years those traces build into scale that narrows the water passages, throws off temperatures, trips flow errors, and eventually locks the unit out entirely. How fast that happens depends on the water and the workload. Homes on municipal supply across both municipalities build scale at a moderate pace, while properties on private wells through the rural Township often run harder water and get there noticeably sooner, and a busy household pushing three bathrooms through one unit accelerates everything. We service the full Langley area, city water and well water alike, and where the water comes from is one of the first questions we ask, because it changes what we expect to find inside the unit.
Descaling is the answer to scale, and it deserves a plain explanation because it gets oversold in this trade. The service flushes a cleaning solution through the heat exchanger to dissolve the buildup and bring flow and temperature stability back, and done when a unit needs it, it is the single cheapest thing you can do to get the long life these systems are known for. It is a standalone service here, booked and priced on its own, never bundled into a diagnostic or slipped into a maintenance visit. We check the heat exchanger's condition during every diagnostic and recommend descaling when the evidence says so, which for some households is regularly and for others is rarely. What we will not do is put every customer on the same calendar and call it maintenance.
The measure of a good tankless repair is simple: one visit, the right part, hot water back the same evening. Getting there takes brand fluency, because each one has its own fault codes and its own sensor quirks, and it takes seeing these units every week, which we do across all six major brands. The licensing behind the work is what gas equipment requires: Technical Safety BC licence LGA0200006, WorkSafeBC coverage, FortisBC Trade Ally status, BBB A+, HPCN registration, and a 4.9 average across more than 400 Google reviews. Replacement parts are CSA certified, and the six-month warranty covers the part and the labour together, so a repair that does not hold is our problem, not yours.
Some units reach the end of the road, usually through a failing heat exchanger or a fault that keeps returning no matter what gets replaced, and at that point we put a replacement quote beside the repair quote and let you compare. New installations come from Navien and Rinnai, in condensing and non-condensing configurations, including models with built-in recirculation that ends the long wait for hot water at the far end of a big Langley house. And for households whose tankless experiment never quite fit, going back to a simple tank is a legitimate answer, not a defeat; that comparison lives on our hot water tank page, and since we install both, the advice follows what your household actually needs.
A failing tank at least leaves you a warm tankful to work through; a tankless lockout is cold water from the next tap onward, which is why these calls get same-day handling across Langley City, the Township, and the rural properties on one schedule. One small thing on your end makes a real difference: if the unit's display is showing an error code, note it down along with the brand when you book. Arriving already knowing what a Navien or Rinnai code points to is often the difference between one visit and two, and most tankless repairs here finish in one.
The owners who get fifteen-plus years out of these units are almost always the ones who dealt with scale early instead of waiting it out, so treat descaling as real maintenance rather than an optional extra, on whatever schedule your water and your household actually require. On the money side, the pattern is the same as every page on this site: $189 to diagnose, exact quotes before any repair, and when replacement is the honest answer, incentive programs shift often enough that we keep the current state of them on our rebates page rather than promising anything here. Financeit's zero percent over 12 months is there when a replacement lands at an inconvenient time, which, with water heaters, is the only time they land.

Same day, in almost every case. A tankless lockout leaves nothing in reserve, so these calls sit at the top of the schedule across both municipalities and the rural Township. Two things speed it up further: tell us the brand when you book, and read out any error code on the display, because knowing both before the truck rolls means the technician arrives prepared for your specific unit rather than diagnosing from zero. Most repairs finish in a single visit. Call (604) 535-8434.
Most tankless repair bills have two parts. The first is the $189 diagnostic, which covers reading the fault, testing the components involved, and inspecting the heat exchanger. The second is the repair itself: the common single components, flame rods, flow sensors, inlet filters, mostly land around $150 to $200 in parts and labour, ignition boards and gas valves run higher, and heat exchanger trouble usually opens the replacement conversation instead of a repair. Descaling is booked and priced as its own separate service. Every number is quoted exactly and approved by you before anything happens, and the warranty runs six months on parts and labour.
Not by itself, and it is worth understanding why. The wait is caused by distance: all the cooled-off water sitting in the pipe between the heater and the tap has to clear before hot water arrives, and that is true whether a tank or a tankless unit is doing the heating. What actually fixes it is recirculation, which keeps hot water staged in the loop so the far bathroom gets it in seconds. Some tankless models come with a recirculation pump built in, and some existing setups can have it added. On the bigger homes and acreages around Langley where a bathroom can sit a long pipe run from the mechanical room, it is one of the most appreciated upgrades we install, and it is worth raising during any diagnostic or replacement conversation.
Fair question, because it does get sold as an upsell by companies that descale everyone on the same schedule regardless of need. The honest version: scale buildup in the heat exchanger is the number one thing that degrades and eventually kills tankless units, so descaling is genuinely necessary, but how often depends entirely on your water and your usage. A big household on hard well water needs it regularly; a couple on municipal supply might go years between services. Our rule: the heat exchanger gets checked during every diagnostic, and descaling gets recommended when the condition of yours says so. Done that way, it is the cheapest insurance a tankless owner can buy.
Not a bad idea, just one that comes with homework. Harder well water loads the heat exchanger with scale faster than municipal supply does, which means the symptoms scale causes, temperature wobble, flow errors, lockouts, arrive sooner and descaling shifts from occasional to routine. Water treatment equipment ahead of the heater changes the picture substantially and is worth pricing if you are committed to tankless on a well. For the well-supplied properties we already service across the rural Township, the practical advice is simple: when the temperature starts wandering, think scale first, and do not wait for a lockout to book the visit. The units themselves are the same proven Navien and Rinnai hardware anywhere; well water just shortens the time between services.
The pattern matters more than the age. A 14-year-old unit failing for the first time on a cheap component can absolutely be worth fixing; a unit on its second or third round of the same fault, or one with heat exchanger damage, is telling you where this is headed, and at that point the money usually argues for replacement. What you get for it is current condensing efficiency, a fresh factory warranty, and the option of built-in recirculation if the far-bathroom wait has been bugging you for years. We put the repair number and the Navien or Rinnai replacement number side by side during the diagnostic, and you make the call with both prices in front of you.
