Why Edmonton Homeowners Choose Acclaimed! Heating, Cooling & Furnace Cleaning

We’ve earned 10 consecutive Northern Alberta Consumer Choice Awards, hold a BBB A+ rating, and carry Baeumler Approved contractor status. Those aren’t just plaques on a wall. They reflect 30 years of showing up, communicating clearly, and doing the work right. Our family-owned business was founded by Keven and Tami Lackey, and that ownership is felt in how every job is handled.

Our technicians are fully licensed, bonded, and insured, and they train continuously at our own Acclaimed! campus to stay current with the brands and systems installed in Edmonton homes. When one of our techs arrives, you’ll recognize the clearly marked truck and clean uniform, and you’ll have already received a pre-arrival notification with the technician’s photo. After the job, we follow up with warranty registration and documentation. No surprises, no chasing paperwork.

Warranties are available on repair work, and financing through FinanceIt is an option for those who’d prefer to spread the cost over time.

Common Tankless Water Heater Problems We Fix

Tankless units are reliable, but they do develop specific faults. Edmonton’s moderately hard water makes some of these issues more common here than in softer-water cities, and knowing what to watch for helps you act before a minor fault becomes a costly one.

Scale & Mineral Buildup in the Heat Exchanger
Hard water accelerates calcification inside the heat exchanger. Left unchecked, mineral deposits restrict flow, drop efficiency, and trigger error codes. Professional flushing removes the buildup and can restore normal operation.

Ignition & Flame Failures
If the unit attempts to fire but won’t light, the cause is usually a gas supply issue, obstructed venting, or a faulty igniter or flame sensor. Each possibility requires systematic diagnostics to isolate.

Temperature Fluctuations
Water that swings between hot and cold during a shower typically points to a flow sensor fault, a control board issue, or scale-related flow restriction. The fix depends on the root cause, not just the symptom.

Error Code Display
Modern tankless units communicate faults through digital codes. Accurate interpretation requires trained diagnostics. Guessing at the code often leads to parts being replaced unnecessarily.

Venting & Condensate Problems
Blocked or incorrectly routed venting can trigger safety shutdowns and create combustion risks. Condensate drains that back up cause related issues that compound quickly.

Freezing During Edmonton Winters
Extreme cold can freeze pipes or internal components. If your unit stops working during a cold snap, prompt emergency response can help limit the damage.

Repair or Replace: How We Help You Decide

A tankless water heater that’s properly maintained can last 15 to 20 years. When a fault develops, repair is usually the right call if the unit is within that service life and the problem is isolated. Replacement makes more financial sense when repair costs approach the value of the remaining service life, or when the same unit has needed repeated repairs in a short span.

Frequent faults on an aging unit often signal cumulative wear that a single repair won’t resolve. We’ll assess your specific unit and give you an honest read on which direction makes sense so you can make the decision that fits your household.

Comfort Club Membership: Stay Ahead of Repairs

Most serious tankless performance problems are preventable. Annual flushing removes the mineral scale that causes heat exchanger failures, error codes, and efficiency loss. Our Comfort Club membership starts at $16.49/month and includes an annual tune-up, discounts on parts and service, automated service reminders, and priority scheduling when you do need a repair call.

Keeping up with professional maintenance may also be required to maintain manufacturer warranty validity on your unit. The membership can pay for itself quickly and keeps your system running through Edmonton’s full range of seasons.

What Our Tankless Water Heater Repair Service Covers

Every repair visit starts with a thorough diagnostic assessment, not a quick guess. Our technicians work through the full system: heat exchanger, burner and igniter, gas valve or electrical supply, flow sensor, inlet filters, condensate drain, venting, and control board. We identify the root cause before quoting the repair, and we provide upfront pricing before any work begins. No hidden fees, no surprises.

As certified dealers and service providers for Rheem, Carrier, Rinnai, and Navien, our technicians are factory-trained on the brands most commonly installed in Edmonton homes. Repairs are completed to manufacturer specifications, the system is tested end-to-end before we call the job done, and descaling is performed as part of the visit when buildup is found.

Signs Your Tankless Water Heater Needs Repair

Some problems are obvious. Others develop slowly and are easy to overlook until the unit stops working entirely. If you’re seeing any of the following, it’s worth calling for a professional assessment before the issue gets worse.

No hot water or significantly reduced flow: The clearest signal that something is wrong. Don’t wait on this one.
Fluctuating water temperature: Water cycling between hot and cold during use points to a sensor, flow, or scale problem.
Error codes on the display: The unit is flagging an internal fault. Accurate diagnosis requires a trained technician, not a quick internet search.
Unusual noises: Banging, hissing, or popping sounds during operation can indicate scale buildup or a failing component.
Visible moisture around the unit: Any leaking or pooling water warrants prompt inspection to avoid water damage.
Discoloured or odorous water: Rust-coloured or foul-smelling output may indicate internal corrosion or contamination.
Rising energy bills: A unit working harder to compensate for scale buildup or a component fault can show up in your utility costs.

If any of these sound familiar, call (587) 741-7517. We serve Edmonton homeowners 24/7 and can often get a technician to you the same day.
