An HVAC warranty is only as good as its fine print. Two systems can advertise a “10-year warranty” and mean completely different things — one covers parts only, the other covers parts and labour. Knowing the difference before you sign can save you thousands over the life of your heat pump or furnace. Here’s how HVAC warranties actually work in British Columbia, what quietly voids them, and the questions that separate real coverage from marketing.
The Three Layers of HVAC Warranty
Manufacturer parts warranty: covers the equipment’s physical components (compressor, heat exchanger, boards) for a set term — typically 10 years on registered residential equipment, sometimes 12 on compressors. It does NOT cover the labour to diagnose and swap the part.
Labour warranty: covers the cost of the technician’s time to perform a warranty repair. This is the one most often missing from cut-rate quotes — without it, a "free" warranty part still costs you a service call and labour.
Contractor workmanship guarantee: covers problems caused by the installation itself (refrigerant leaks at brazed joints, poor airflow, bad electrical). A quality installer stands behind their own work for a defined period.
Why “10-Year Warranty” Can Mean Very Different Things
When a quote says "10-year warranty," ask: parts only, or parts and labour? A parts-only warranty means that in year 6, a failed component is free but you pay $200–$600 in labour to install it. A parts-and-labour warranty covers both.
DirectBuy Furnace installs come with a 10-year parts AND labour warranty — see what’s included on any heat pump installation or furnace installation page. Always get the labour term in writing, because it is the single biggest difference between two superficially identical quotes.
Registration: The Deadline That Halves Your Warranty
Most manufacturers (Trane, Carrier, Mitsubishi, Daikin, Lennox) require you to register the equipment within 60–90 days of installation to receive the full 10-year term. Miss the window and the warranty often drops to the base 5 years automatically.
A professional contractor registers the equipment for you and provides written confirmation. If you installed equipment recently and aren’t sure it was registered, check now — the deadline is unforgiving, and re-registration after the window usually isn’t allowed.

Unlicensed installation: manufacturers can void coverage if the equipment wasn’t installed by a qualified contractor with the proper permits.
Skipped maintenance: most warranties require documented annual maintenance. Keep your service records — manufacturers can deny claims without proof the system was maintained.
Wrong or no air filter: running a system with a clogged or missing filter is a common cause of denied compressor and heat-exchanger claims.
Unauthorized repairs: having a non-qualified person open the equipment can void coverage. Use a licensed tech for anything beyond filter changes.
Improper sizing or modifications: aftermarket changes and grossly mis-sized systems can be grounds for denial.
Heat Pump vs Furnace Warranty Considerations
Heat pumps run year-round (heating and cooling), so they accumulate more operating hours than a furnace that only runs in winter. That makes the labour-warranty term especially valuable on a heat pump — and makes documented annual maintenance more important for keeping coverage intact.
Furnaces have a critical safety component — the heat exchanger — that usually carries its own longer warranty (often 20 years or lifetime on premium models) because a cracked heat exchanger is a carbon monoxide risk. Confirm the heat-exchanger term separately from the general parts term.
Questions to Ask Before You Sign
Is the warranty parts-only or parts AND labour, and for how many years each?
Who registers the equipment, and by when must it be registered?
What is your workmanship guarantee on the installation itself?
What maintenance is required to keep the warranty valid, and do you offer a maintenance plan?
Is the heat-exchanger (furnace) or compressor (heat pump) covered for a longer separate term?
Get every answer in writing. A contractor confident in their work will put it on paper without hesitation. DirectBuy Furnace does — call 604-210-9585 or estimate your project with the rebate calculator first.
Frequently Asked Questions
What is the difference between a parts and a labour warranty?
A parts warranty covers the cost of failed components; a labour warranty covers the technician’s time to install them. Many cheap quotes include parts only, so a "free" warranty part still costs you a service call. Always confirm both in writing.
How long are HVAC warranties in BC?
Manufacturer parts warranties are typically 10 years on registered residential equipment (sometimes 12 on compressors, longer on furnace heat exchangers). Labour and workmanship terms vary by contractor — DirectBuy Furnace provides 10-year parts and labour.
Do I have to register my HVAC equipment?
Usually yes. Most manufacturers require registration within 60–90 days of installation to keep the full 10-year term; miss it and coverage often drops to 5 years. A good contractor registers it for you and gives written confirmation.
What voids an HVAC warranty?
Common causes: unlicensed installation, skipped/undocumented annual maintenance, running without a proper filter, unauthorized repairs by non-qualified people, and improper sizing or modifications.
Does annual maintenance affect my warranty?
Yes. Most manufacturer warranties require documented annual maintenance. Keep your service records — claims can be denied without proof the system was properly maintained.
