Hot-water temperature fluctuates or flow drops unexpectedly
Hot water, maintained with clarity
Tankless Water Heater Service
A tankless service framework covering accessible water, gas, venting, condensate and control components, with descaling discussed according to equipment condition and scope.
Maintenance or active fault
Know which problem the appointment needs to solve.
Maintenance can include applicable cleaning, inspection and descaling, but the exact descaling scope depends on isolation valves, water condition and manufacturer guidance. Error-code diagnosis, parts and leak repair are separate work.
The controller displays an error or the unit repeatedly shuts down
Scale, condensate or leakage is visible around accessible components
Ignition, venting or unusual operating noise has changed
The visit starts with the actual intent.
Maintenance can include applicable cleaning, inspection and descaling, but the exact descaling scope depends on isolation valves, water condition and manufacturer guidance. Error-code diagnosis, parts and leak repair are separate work.
Make the larger decision with evidence.
The decision should account for heat-exchanger condition, venting, water quality, maintenance history, error history, part availability and whether a new unit would require gas, electrical, condensate or piping changes.

A clear service scope before the visit.
The booked appointment covers the confirmed service scope. If diagnosis reveals a separate repair or part, the customer should receive an explanation and price before authorizing additional work.
Operating and error-code review
Accessible safety, venting and water-side observations
Cleaning and descaling scope confirmed for the unit
15-point tankless framework
Clear findings and next-step explanation
Equipment-specific · not generic
The tankless water heater 15-point framework.
Each point explains what is reviewed and why it matters. Accessibility, equipment design, operating conditions and manufacturer requirements determine the exact steps completed.
- 01Service
Equipment identification
Confirm model, fuel, installation configuration and the reported hot-water concern.
- 02Performance
Controller and error history
Review available codes, set point and control response.
- 03Safety
Gas shutoff and connections
Identify the accessible shutoff and review accessible connection condition.
- 04Safety
Venting and combustion air
Visually inspect accessible venting, intake and termination condition.
- 05Condition
Water connections
Inspect accessible hot, cold and isolation connections for leakage or corrosion.
- 06Cleaning
Inlet filter or screen
Inspect and clean the accessible inlet screen where included and appropriate.
- 07Cleaning
Scale condition
Assess scale indicators and confirm whether flushing or descaling is included or separately required.
- 08Condition
Heat exchanger
Review accessible condition and operational indicators without overstating hidden surfaces.
- 09Performance
Ignition and flame proving
Observe the ignition sequence and flame-proving response.
- 10Performance
Flow activation
Check that the unit recognizes water flow and responds at available fixtures or test points.
- 11Safety
Safety controls
Review applicable over-temperature, flame and shutdown controls within scope.
- 12Condition
Condensate system
For condensing units, inspect accessible drain, trap and neutralizer condition.
- 13Safety
Electrical condition
Inspect accessible power connection and wiring condition.
- 14Performance
Outlet temperature
Compare delivered temperature with set point under suitable flow conditions.
- 15Service
Final cycle and report
Confirm operation and explain maintenance completed, limitations and next steps.
This framework communicates B.C HVAC's intended service structure. The assigned qualified professional confirms the safe, applicable and accessible work for the specific installation. It is not a substitute for the equipment manufacturer's service instructions.
A visible next step
How diagnosis becomes an informed decision.
The booked scope, any repair and any replacement estimate remain distinct so the customer can see what is being authorized.
- 01
Capture the error and demand
Share displayed codes, when hot water fails, fixture flow and whether other gas appliances operate.
- 02
Review water, fuel and controls
The visit connects operating data with accessible water, venting, condensate and qualified combustion observations.
- 03
Confirm maintenance or repair
Descaling, replacement parts and installation changes are identified and authorized as separate scope where required.
Before you book
Questions customers ask.
Plain answers about price, scope, safety and what happens if the service identifies a repair.
Is descaling included in every $99 visit?
The need, access and scope vary by unit and water condition. Confirm whether flushing or descaling is included when booking rather than assuming it is.
Does FortisBC offer a rebate?
FortisBC currently lists a maintenance rebate for an eligible tankless water heater. Storage-tank water heaters are not included in that specific program.
Can an error code be cleared without repair?
An error code identifies a condition, not always the cause. The technician should diagnose the reason before recommending a reset, adjustment or repair.
Independent customer guidance
Use authoritative sources for safety and program rules. B.C HVAC does not control utility rebates or provincial qualification requirements.
