Metro Vancouver homeowners lose money and risk safety when they hire an unlicensed or corner-cutting HVAC contractor. Here are the red flags to watch for before you sign anything.

Quick answer: Unreliable HVAC contractors show consistent warning signs: no Technical Safety BC gas licence number, vague or verbal-only quotes, pressure to decide same-day, no fixed business address, cash-only demands, and reluctance to pull permits for gas or electrical work. A trustworthy Metro Vancouver contractor provides licence numbers, a written itemized quote, and stands behind the work in writing.

Metro Vancouver's housing stock includes a large share of older homes, converted character houses, and condos or townhomes with shared mechanical rooms, strata approval requirements, and tight equipment closets. Gas furnaces, boilers, and gas fireplaces all involve combustion appliances that vent exhaust gases out of the home, and heat pump or furnace electrical hookups involve dedicated circuits. In BC, gas fitting and most HVAC electrical work legally require a licensed, insured contractor working under permit through Technical Safety BC. An unreliable contractor who skips licensing, permits, or proper venting checks isn't just a bad customer experience — it can mean improperly vented combustion gases, code violations that surface at resale, or a job a strata council refuses to sign off on.
A legitimate contractor inspects the equipment, existing venting, gas line sizing, electrical panel capacity, and access before quoting — especially for boiler installation, furnace replacement, or heat pump sizing, where getting the equipment size wrong leads to short-cycling, poor comfort, or premature failure. Watch for these behaviours during the visit itself.
| Behaviour | What it usually means |
|---|---|
| Refuses to put the quote in writing | No accountability if the final bill differs from what was discussed |
| High-pressure "today-only" discount | Designed to stop you from getting a second quote |
| Can't explain why a specific size or model is recommended | Sizing may not be based on an actual heat-loss or load calculation |
| Demands full payment upfront, especially in cash | Reduces your leverage if the work is incomplete or defective |
| Dismisses your questions about permits | May be planning to skip the permit entirely |
| No mention of warranty on labour or parts | You may have no recourse if something fails in year one |

📞 (604) 359-1081 Request a free quoteBefore you ever call a contractor, you can do some of your own homework. You can ask for and note down a company's Technical Safety BC licence number, look up whether the business has a consistent name and address across its website, invoices, and vehicle signage, and read a broad sample of reviews rather than just the newest ones. You can also ask straightforward questions by phone: How long have you served Metro Vancouver? Are your technicians Red Seal certified? Will you pull a permit for this job? A contractor confident in their credentials will answer without hesitation.
What you should not do yourself is inspect or work on live gas piping, venting connections, or the electrical circuit feeding a furnace, boiler, or heat pump. Disconnecting or probing these components without training risks a gas leak, carbon monoxide exposure, or electrical shock, and altering gas or electrical connections without a licensed technician is against BC law regardless of your intentions.
A trustworthy visit follows a predictable pattern: the technician arrives in a marked vehicle, identifies themselves, inspects the existing system and surrounding conditions (venting, gas line, electrical panel, clearances), asks about your comfort issues or symptoms, and explains findings in plain language before recommending options. For anything involving gas or electrical work, they should state upfront that a permit will be pulled through Technical Safety BC and explain roughly what that involves. You should receive an itemized written quote, not just a total number, and be told what warranty applies to both labour and equipment.
If cost ranges come up, a reliable contractor should be able to explain what drives the number — equipment sizing, venting changes, gas line upsizing, electrical upgrades, and permit fees — rather than quoting a number with no context. As a general reference point for Metro Vancouver, installed pricing before rebates typically runs $4,500-$9,500+ for a furnace, $6,500-$14,000+ for a boiler, $6,000-$18,000+ for a heat pump, roughly $3,500-$7,500 for a tankless water heater, and $3,500-$8,000+ for a gas fireplace — but your home's specific access, venting, and electrical situation is what ultimately sets the final number, which is why a free written quote after an in-person visit matters more than a phone estimate.
A contractor who avoids the topic of permits entirely is a warning sign in itself. Gas and electrical HVAC work in BC requires permits and inspection through Technical Safety BC, and a licensed contractor should handle this as a normal part of the job, not treat it as optional paperwork you can skip to save money. Similarly, be cautious of anyone promising a specific rebate dollar amount upfront. The Canada Greener Homes Grant closed to new applicants in early 2024, so a contractor still advertising that grant is either outdated or misleading. Legitimate current options include the interest-free Canada Greener Homes Loan (up to $40,000), the Oil to Heat Pump Affordability program, and rebates through CleanBC, BC Hydro, and FortisBC — but exact figures change, so a reliable contractor will tell you to confirm current amounts at quote time rather than quoting you a guaranteed number on the spot.
⚠️ Safety note: Any contractor who offers to skip a permit on gas piping, a furnace/boiler venting change, or an electrical circuit for your HVAC system is asking you to break BC law and put your household at risk — gas and electrical work legally requires a licensed, permitted tradesperson in British Columbia. If you ever smell gas (a rotten-egg odour) after work has been done, leave the home immediately, do not operate switches or your phone inside, and call the FortisBC emergency line at 1-800-663-9911 from outside. If you notice symptoms of carbon monoxide exposure — headache, dizziness, nausea, confusion — get everyone outside into fresh air right away and call 911; do not go back in to investigate.
