Choosing the wrong HVAC contractor is an expensive mistake. A botched heat pump or furnace install can void your equipment warranty, disqualify you from thousands in BC Hydro rebates, and leave you with a system that never performs as promised. In the Fraser Valley — Abbotsford, Chilliwack, Mission, Langley, and Maple Ridge — the spread in quality between contractors is wide. This is the exact checklist we'd use ourselves to vet an installer, written plainly so you can hold any contractor (including us) to it.
Why the Contractor Matters More Than the Equipment
Most homeowners obsess over which brand of heat pump or furnace to buy. The truth is that installation quality matters far more than the badge on the equipment. A premium Trane or Mitsubishi system installed badly — wrong size, poor refrigerant charge, leaky ductwork — will underperform a mid-tier unit installed correctly. Studies of residential HVAC consistently find that improper installation can cut efficiency by 20–30%.
In British Columbia there is a second reason the contractor matters: rebates. BC Hydro and CleanBC will only pay rebates on installs done by approved contractors using qualified equipment, documented correctly. The wrong contractor can cost you the entire rebate stack — often several thousand dollars. See our BC Hydro rebate guide for exactly how that qualification works.
Check 1: Licensing and Gas-Fitter Certification
Any contractor installing or replacing a gas furnace, boiler, or gas water heater in BC must employ TSBC-certified (Technical Safety BC) gas fitters and pull a gas permit. Ask for the certification number and confirm the company is licensed, bonded, and insured in BC. This is non-negotiable — uncertified gas work is both illegal and dangerous.
For electrical work tied to a heat pump (new 240V circuits, panel upgrades), the contractor should either hold the appropriate electrical credentials or sub to a licensed electrician who pulls an electrical permit. If a contractor waves off permits as "not needed for a simple swap," walk away.
Check 2: BC Hydro Network of Excellence Status
BC Hydro only accepts heat pump rebate applications from contractors on its Network of Excellence list. If your installer isn't on it, you cannot claim the BC Hydro rebate — full stop. This single check eliminates a large share of cut-rate operators.
Ask directly: "Are you a BC Hydro Network of Excellence contractor, and will you submit the rebate paperwork on my behalf?" A reputable Fraser Valley installer handling heat pump installation in Abbotsford or Chilliwack will answer yes without hesitation and include the paperwork at no extra charge.

Get the quote in writing, itemized: equipment make and model, sizing rationale, electrical/ductwork scope, permit fees, and the rebate amounts the contractor expects you to qualify for. Verbal-only quotes and "today only" pricing are red flags — legitimate HVAC pricing does not expire at midnight.
A good contractor performs a proper load calculation (Manual J or equivalent) rather than guessing system size from square footage alone. Oversized systems short-cycle, waste energy, and wear out early; undersized systems never keep up in a cold snap. If a contractor quotes a size in five minutes without measuring anything, be skeptical.
Check 4: Warranty — In Writing, Parts AND Labour
Confirm both the manufacturer parts warranty (typically 10 years on registered equipment) and the contractor's own labour/workmanship guarantee. The cheapest quote often omits labour coverage, which means a warranty "repair" still costs you hundreds in trip and labour fees. Our deeper breakdown is in the BC HVAC warranties guide.
Ask who registers the equipment warranty. Many manufacturers require registration within 60–90 days of install or the warranty drops from 10 years to 5. A professional contractor registers it for you and gives you the confirmation.
Check 5: Permits, Inspections, and Local Track Record
Every furnace, boiler, and most heat pump installs in the Fraser Valley require a permit and a Technical Safety BC inspection. A contractor who pulls permits is one who expects their work to be inspected. Skipping permits can void insurance and create problems when you sell the home.
Local track record matters in the Fraser Valley specifically because the climate is harsher than coastal Vancouver — colder winters in Abbotsford, Mission, and Chilliwack demand cold-climate equipment correctly sized for sub -15°C snaps. A contractor who regularly works furnace installation in Langley or Mission understands this; an out-of-area operator may undersize for the valley.
Red Flags to Walk Away From
No permit / "we don't need one for this": almost always false for gas and major electrical work.
Cash-only or large upfront deposits before any work: legitimate contractors invoice on milestones and accept traceable payment.
No load calculation and instant sizing: a guarantee of an over- or under-sized system.
Pressure tactics and expiring prices: real quotes hold for a reasonable window.
No written warranty, or labour excluded: you will pay for "warranty" repairs.
Not on the BC Hydro Network of Excellence list but promising rebates: the rebate will not be paid.
How to Run the Checklist
Get two or three written quotes, run each contractor through the eight checks above, and compare on total installed cost after confirmed rebates — not just sticker price. The cheapest quote that excludes labour warranty and rebate handling is usually the most expensive once something goes wrong.

Frequently Asked Questions
Do I need a licensed contractor for a furnace install in BC?
Yes. Gas furnace, boiler, and gas water heater installs in BC legally require TSBC-certified gas fitters and a gas permit. Uncertified gas work is illegal and can void your home insurance.
Why does my contractor need to be on the BC Hydro Network of Excellence list?
BC Hydro only pays heat pump rebates on installs completed by Network of Excellence contractors. If your installer is not on the list, you cannot claim the BC Hydro rebate, regardless of the equipment.
How many HVAC quotes should I get?
Two or three written, itemized quotes is the sweet spot. Compare on total installed cost after confirmed rebates and warranty coverage, not just the headline price.
What is a load calculation and why does it matter?
A load calculation (Manual J or equivalent) sizes the system to your specific home. Oversized systems short-cycle and wear out early; undersized systems can't keep up in a cold snap. A contractor who sizes by guesswork is a red flag.
Are permits really required for HVAC work in the Fraser Valley?
Yes — gas and most heat pump installs require a permit and a Technical Safety BC inspection. A contractor who skips permits is a warning sign and can create insurance and resale problems.
