Regular maintenance reveals problems before they become breakdowns. Here are the issues Gas Services Edmonton finds and corrects most often during maintenance visits.

🪨

Tankless Heater Not Heating as Well Anymore

Mineral deposits from hard water accumulate inside the heat exchanger coils and progressively restrict water flow and heat transfer. The unit compensates by working harder, which stresses the gas valve and burner, until a thermal shutdown eventually occurs. Annual descaling prevents this buildup from reaching the point where it causes operational faults or permanent damage.

🚿

Tankless Heater Inlet Filter Blocked

The inlet filter protects the flow sensor and heat exchanger from sediment in the water supply, but when it becomes saturated, it restricts water flow to the unit. Restricted flow causes the unit to shut down on low-flow protection and can trigger persistent error codes. Cleaning or replacing the filter during maintenance restores proper water delivery.

Tankless Heater Igniter Wearing Out

Ignition electrodes wear gradually and eventually develop fouling or physical cracking that reduces spark reliability. A degraded electrode may still light the unit under ideal conditions but fail during high-demand periods or when gas pressure fluctuates slightly. Catching and replacing a worn electrode during maintenance prevents a no-ignition fault call later.

🔥

Tankless Heater Flame Sensor Dirty

Combustion residue coats the flame sensor surface over time, insulating it and causing the control board to cut the gas supply even when the burner is producing a flame. The result is a unit that lights briefly and then shuts down, often triggering a fault lockout. Cleaning the sensor during a maintenance visit resolves this before it causes a service interruption.

🔩

Tankless Heater Gas Pressure Off Range

Gas supply pressure can drift outside the optimal operating range for the unit over time, affecting combustion quality and heating output without producing an immediate error code. A technician measuring live gas pressure during a maintenance visit can identify and correct this condition before it leads to incomplete combustion or premature component wear.

🌡️

Tankless Heater Delivering Lukewarm Water

Temperature sensors used by the control board to regulate gas output can develop reading inaccuracies as they age. A thermistor that reads slightly high causes the unit to reduce gas flow before the target temperature is reached, resulting in lukewarm output. Maintenance visits include sensor testing so degraded thermistors are identified and replaced before they affect the homeowner's experience.

💨

Tankless Heater Shutting Down Unexpectedly

Venting blockages from debris, bird nests, or condensate line restrictions cause back pressure in the exhaust system that triggers safety switches and reduces combustion efficiency. These issues are not visible from inside the home and often go unnoticed until the unit starts shutting down unexpectedly. Venting inspection during each maintenance visit catches these problems early.

📅

Tankless Heater Not Serviced in Over a Year

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.

🚿

No Hot Water at All

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.

What Our Customers Say

★★★★★

Fair pricing and no surprises

Gas Services Edmonton explained exactly what the quote covered before starting and the final bill matched exactly what we were told. No hidden add-ons, just a clear breakdown of the work performed.

★★★★★

Glad we caught up after a few skipped years

We had not had our unit serviced in about three years and the Gas Services Edmonton technician was upfront that the flush would take a bit longer because of it. Worth every penny once we saw how much better the unit performed afterward.

★★★★☆

Good value, appointment ran a little long

The visit took longer than expected since our unit is in a tight mechanical closet, but the technician explained why upfront and the price reflected that accurately. Solid work overall.

★★★★★

Bundled two appliances and saved money

Asked if they could also check our furnace while they were here for the water heater maintenance and they said yes right away. Ended up saving compared to booking two separate visits.

★★★★★

Explained our hard water situation clearly

The technician from Gas Services Edmonton walked us through why our well water meant a shorter maintenance interval made sense for our unit. Appreciated the honest, specific explanation rather than a generic answer.

★★★★★

Noticed the gas bill difference immediately

Our bill dropped noticeably the month after the maintenance visit. The technician mentioned this was likely since the unit was running more efficiently after the descale, and it really showed.
