Water Heater Repair in Calgary

It depends entirely on what failed. A thermocouple or an anode rod is among the cheapest work we do. A heating element or a thermostat is a step up. A gas control valve on a larger unit is a serious part and costs accordingly, and a tankless descale is its own job again.

We diagnose first and quote before we touch anything, so you decide with the real number in front of you rather than a guess over the phone.

And if the repair doesn't make sense — if the tank is finished, or you'd be spending a large fraction of a new unit's price on an old one — we'll tell you that instead of quietly doing the work.

Usually, yes. We carry the common failure parts on every truck — elements, thermostats, thermocouples, gas control valves, anode rods, and relief valves — so most water heater repairs finish on the first visit.

Where we can't is when a unit needs a brand-specific part that has to be ordered, which happens more with tankless units and discontinued models. We'll tell you that on the call rather than after we've arrived.

Age is the biggest factor. Tank water heaters in Calgary typically last 8-12 years — our hard water is hard on them — and tankless units run 15-20 with proper maintenance.

Under about 8 years, a tank with a single failed part is usually worth repairing. Past 12, we'd generally steer you toward replacement even when the specific fault is fixable, because the next failure is already on its way.

Two hard rules regardless of age: a tank leaking from the body is not repairable by anyone, and a repair that costs a large fraction of a new unit on an old heater is money badly spent. We'll show you the math and let you choose.

On an electric heater, this is usually a failed heating element — often the lower one, which is why you sometimes get a little hot water before it runs cold. The thermostat can also fail, or the high-limit safety can trip and need a reset.

On a gas heater, the burner may not be lighting at all even though the pilot looks fine. That points at the thermocouple or the gas control valve.

All of it is diagnosable in one visit. Our no hot water page walks through the symptoms in more detail if you want to narrow it down first.

Yes — gas and electric both. Tankless repair is more specialized than tank work: there are error codes to read, flow sensors and flame rods to test, and the units are less forgiving of a guess.

The most common tankless job we do in Calgary isn't really a repair at all — it's a descale. Our hard water scales the heat exchanger, and a scaled exchanger is why most underperforming tankless units underperform. If yours has never been descaled and it's a few years old, start there.

Almost always the water. Calgary's hard water leaves mineral sediment in the bottom of a tank and scale on a tankless heat exchanger, and both make the unit work harder and die younger than the manufacturer intended.

Two things fix it. An annual flush clears the sediment out before it can do damage, and it's cheap insurance. A water softener upstream is the permanent solution — it treats the cause rather than the symptom, and it protects your fixtures, your dishwasher, and any boiler on the same supply.

If your heater has failed early and it's never been flushed, that's your answer.

It can be. Water pooling around the base might be something minor and repairable — a loose fitting, the drain valve, or the T&P relief valve doing its job.

But it might also be the tank body corroding through, and a tank that's weeping today can let go properly with very little warning. If you're seeing water and you can't tell where it's coming from, shut off the water supply to the heater and call us. Our leaking water heater page has the shutoff steps.

A tank unit: 8-12 years, and the low end of that is common here because of the water. Diligent annual flushing and replacing the anode rod when it's spent can push a tank to 15.

A tankless unit: 15-20 years *with* annual descaling. Without it, a tankless heater in Calgary water can fail in well under a decade — most of the dead tankless units we replace died of neglected maintenance, not old age.
