Tankless Water Heater Maintenance in Etobicoke
Annual maintenance is the difference between a tankless unit that lasts 15 years and one that starts causing problems at year eight. We descale, inspect, and test every component.

A homeowner in Mimico called us after their five-year-old Rinnai tankless unit started displaying an error code and producing inconsistent water temperatures. When our technician flushed the heat exchanger, the amount of mineral scale that came out explained everything — the unit had never been descaled since installation. After a full maintenance service, the error codes cleared and the unit was back to peak performance. The technician noted the heat exchanger had taken more buildup than typical, but caught it before any real damage was done. One service visit extended the useful life of that unit by several years.
What We Do on Every Maintenance Visit
Tankless water heaters are widely described as low-maintenance appliances, which is true relative to many other home systems. But low maintenance doesn't mean no maintenance. Annual service is the difference between a unit that lasts 15-plus years and one that starts causing problems at year eight or nine.
Our licensed technicians follow a detailed service process designed to address every component that affects long-term performance and safety.
Why Regular Maintenance Protects Your Investment
Annual service is the single most effective thing you can do to protect the lifespan and efficiency of your tankless unit.
Prevents Costly Repairs
Scale buildup left unaddressed leads to overheating, component stress, and eventually heat exchanger damage — one of the more expensive repairs on a tankless unit. Annual descaling prevents the problem entirely.
Maintains Energy Efficiency
A scaled-up heat exchanger has to work harder to transfer the same amount of heat. The efficiency advantage of your tankless unit erodes with buildup. Regular maintenance preserves the efficiency gains you invested in.
Keeps Your Warranty Valid
Most manufacturers require documented annual professional service as a condition of warranty coverage. We provide service records for every maintenance visit so your warranty stays intact.

How Often Should You Service Your Unit?
Annual Service (Most Homes)
Annual maintenance is the standard recommendation and is required by most manufacturers to keep warranty coverage valid. One visit per year covers descaling, filter cleaning, ignition inspection, venting check, and a full performance test.
Every 6 Months (Hard Water Areas)
For homes with harder water — common in parts of South Etobicoke — we may recommend a descaling service every six months to stay ahead of mineral buildup. We'll advise based on your unit and water conditions.
Book Sooner If You Notice Issues
Inconsistent temperatures, error codes on the display, reduced hot water flow, or a unit that hasn't been serviced since installation are all signs to book a maintenance visit sooner rather than later.
We Provide Service Records
We document every maintenance visit with a service record. This keeps your manufacturer warranty valid and gives you a clear history of what's been done — useful if the unit ever needs a warranty claim.
Flexible Financing Available
Whether you're booking a routine annual service or addressing a repair identified during maintenance, we offer flexible financing options to help manage the cost.
We offer flexible financing through trusted lenders — including 0% interest for 12 months with approved credit. Spread the cost over time with monthly payment plans designed to fit any budget.

Tankless Water Heater Maintenance in Etobicoke
How often should I schedule tankless water heater maintenance?
Once a year is appropriate for most homes. Homes with hard water or households with very high hot water usage may benefit from a descaling service every six months. We'll give you a recommendation based on your specific unit and water conditions.
What is included in tankless water heater maintenance?
A full service includes heat exchanger descaling, inlet filter cleaning, burner and ignition inspection, venting check, sensor and safety component testing, and a complete performance test to confirm the unit is operating correctly.
Why is descaling important for tankless water heaters?
Scale from dissolved minerals accumulates on the heat exchanger surfaces over time. It reduces heat transfer efficiency, restricts water flow, and can cause the unit to overheat and trigger fault shutdowns. Left unaddressed for long enough, heavy scale buildup can permanently damage the heat exchanger. Annual descaling prevents all of this.
Can regular maintenance extend the life of my tankless unit?
Significantly. Tankless water heaters are capable of lasting 15 years or more with proper care. Without annual maintenance — particularly descaling — many units start experiencing performance issues and component failures well before the ten-year mark.
What happens if I skip tankless water heater maintenance?
Scale continues to build in the heat exchanger, gradually reducing efficiency and increasing the risk of overheating faults and component stress. The inlet filter can become clogged, triggering flow faults. Ignition components degrade without inspection. Over time, these issues compound into expensive repairs or premature replacement.
How do I know if my tankless water heater needs maintenance?
Inconsistent water temperatures, reduced flow from hot taps, error codes on the display, longer than normal heating times, or a unit that hasn't been serviced in a year or more are all signs to book a maintenance visit.
Is tankless water heater maintenance different from traditional tank water heater maintenance?
Yes. Traditional tank maintenance focuses on anode rod inspection, tank flushing, and pressure relief valve testing. Tankless maintenance centres on heat exchanger descaling, filter cleaning, and inspection of the burner, ignition, sensors, and venting — a more technical service that requires familiarity with the specific unit and manufacturer.
