Most tankless unit failures start with the water, not the hardware. These are the issues we find and resolve most often.
Calcium and magnesium from hard water deposit on the heat exchanger coil with every heating cycle, gradually reducing efficiency and raising operating stress. Severe scale can crack the exchanger, which is the most expensive failure in a tankless system. We perform a complete descaling flush to dissolve and remove all accumulated deposits.
The inlet filter captures sediment before it reaches the heat exchanger, but it needs regular cleaning to maintain proper water flow. A clogged filter reduces output pressure, causes flow-related error codes, and stresses the activation sensor. We clean and inspect the filter as part of every maintenance visit.
A flow sensor coated in sediment or worn from extended use can cause the unit to fail to activate at normal flow rates, deliver inconsistent temperature, or cycle on and off unexpectedly. We clean the sensor and verify its calibration against the unit's operating range during every maintenance appointment.
Hot water pressure that is lower than usual without any plumbing changes typically points to filter restriction or scale buildup narrowing the flow path inside the heat exchanger. Either condition worsens over time without maintenance. We identify the source of the restriction and clear it during the service visit.
Water that swings from warm to cold during use is usually caused by a dirty flow sensor giving the burner inaccurate activation signals, or by a scale-covered heat exchanger that cannot maintain steady output. We address both causes during the same maintenance visit to restore consistent temperature delivery.
Flow and pressure-related error codes are almost always driven by a clogged filter, a misfiring flow sensor, or scale restriction inside the heat exchanger. Resetting the code without fixing the underlying water-side issue causes the fault to return. We clear the root cause and reset the diagnostic system properly.
A partially blocked or corroded vent line reduces the air available for proper combustion, lowering efficiency and triggering safety shutdowns. Venting issues often develop without visible signs inside the home. We inspect the full vent path during every maintenance visit and correct any restriction or connection fault found.
A tankless water heater that has gone more than a year without professional service may have heat exchanger scale, inlet filter buildup, and ignition component wear that compound quietly. The risk of a mid-season lockout or error code increases with each season skipped. We assess the full unit condition during a catch-up maintenance visit and address what needs correction.
A complete loss of hot water usually points to an ignition lockout, a tripped safety switch, or a gas supply interruption that has prevented the unit from firing. Forcing a reset without diagnosing the cause can allow the underlying fault to worsen. We identify the root cause and restore full operation safely.
I had been doing my own filter cleaning but wasn't sure what else was safe to handle. The technician from Gas Services Edmonton walked me through what to keep doing myself and what needed a professional. Really appreciated the honesty.
We tried descaling ourselves last year and apparently missed a step. Gas Services Edmonton caught the issue during our first professional visit and fixed it before it caused real damage. Booking the annual service from now on.
Our unit hadn't been serviced in a couple of years so the visit took longer than the estimate. The technician explained why upfront and the documentation he left behind was worth the extra time.
We had no idea our manufacturer required documented maintenance until Gas Services Edmonton mentioned it during the visit. Now we have proper records in case anything ever goes wrong. Should have called sooner.
The technician knew our unit's specific filter location and descaling solution requirements without having to look anything up. Felt like he had serviced this exact brand a hundred times before. Very reassuring.
Our gas bill had been slowly climbing and we couldn't figure out why. Turned out our heat exchanger had significant scale buildup. After the visit our usage dropped back down within a couple of weeks.
