A gas service call follows a consistent sequence: arrival and safety check, diagnosis, explanation, and either repair or a clear next step.

Quick answer
A gas service call typically starts with the technician confirming the reported issue with you, followed by a visual and instrument-based inspection of the equipment, gas supply, and venting to identify the cause. Once the cause is found, the technician explains it in plain terms and provides a repair quote if one is needed, which you can accept or decline. If parts aren't on hand, a follow-up visit is scheduled; if the issue is straightforward, the repair often happens the same visit.

When a technician arrives, they'll typically confirm what you reported when you booked the appointment, ask any clarifying questions, and ask to see the equipment. This is a good moment to mention anything you noticed that you might not have said on the phone, like a smell, an unusual sound, or a change in performance over time. The technician isn't testing your knowledge of the system; the goal is simply to gather as much relevant information as possible before starting the inspection.
For anything involving a gas smell or suspected leak, this conversation happens differently: safety comes first, and the technician will confirm the area is safe before any other diagnostic work begins.
The technician then inspects the equipment, which can include a visual check of the unit, venting, and gas connections, along with instrument testing using combustion analyzers, pressure gauges, or electrical meters depending on the symptom. This step is methodical by necessity, since gas appliances can fail for several overlapping reasons, and ruling components in or out in a logical sequence is how a technician avoids guessing at a fix.
Once the cause is identified, a good technician explains it in plain language, not just technical shorthand, and provides a clear quote for the repair before doing any additional work. You have the right to ask questions, request the reasoning behind the diagnosis, or decline the repair and get a second opinion. If the technician finds more than one issue, they should explain each one separately rather than bundling them into a single unexplained total.
| Scenario | Typical outcome |
|---|---|
| Common part in stock, straightforward fix | Repair often completed the same visit |
| Specialized or less common part needed | Follow-up visit scheduled once the part arrives |
| Underlying issue points toward replacement | A separate replacement quote and assessment is arranged |
Whether a repair happens immediately or requires a follow-up depends mostly on parts availability, not on the complexity of the diagnosis itself.
A thorough technician tests the fix, if one was made, through a full cycle before considering the job done, explains what was done, and lets you know if anything else is worth watching for. You should leave the visit with a clear understanding of what was wrong, what was fixed or recommended, and, if applicable, a written invoice and quote for any follow-up work.
Occasionally a diagnosis takes longer than expected, particularly on an older system with more than one contributing issue, or when a fault only shows up intermittently and the technician needs to observe a full cycle to catch it. In that case, a good technician explains why more time or a follow-up visit is needed rather than rushing to a conclusion that might not hold up. Being upfront about uncertainty is a sign of a careful diagnosis, not a lack of confidence.
Safety note
If a gas smell or suspected leak is the reason for the service call, the technician prioritizes confirming the area is safe before any other diagnostic work. If you ever smell gas yourself, leave the home and call FortisBC at 1-800-663-9911 before calling for service.
It varies with the complexity of the diagnosis and whether a repair is completed the same visit, but most straightforward calls are resolved within a couple of hours.
Often yes, if the necessary part is commonly stocked; if not, a follow-up visit is scheduled once the part is available.
It helps to be available for questions, especially at the start and end of the visit, though you don't need to watch every step.
Ask them to explain it again in simpler terms; a good technician will walk you through the finding without technical jargon.
Yes, you're free to decline and seek a second opinion, though the diagnostic fee for the visit itself typically still applies.
