Most homeowners assume an HVAC warranty means their entire heating or cooling system is fully protected for 10 years or more.
In reality, HVAC warranties in Alberta are usually more limited than most people expect.
A typical warranty is split into different categories of coverage, and understanding these differences is the key to avoiding surprise repair costs.
What Most HVAC Warranties DO Cover
Most manufacturer warranties include parts coverage, which protects against defective components. This can include furnace heat exchangers, blower motors, air conditioner compressors, control boards, and sensors and electrical components.
If a part fails due to manufacturing defects, it is typically replaced under warranty.
What HVAC Warranties DO NOT Cover
This is where most homeowners are surprised.
Most warranties do NOT include labour costs to install replacement parts, diagnostic service fees, emergency or after-hours service calls, refrigerant or consumables, maintenance or cleaning, and travel time for technicians.
These costs can often exceed the price of the part itself.
Why Labour Coverage Matters
Labour is often the largest hidden cost in HVAC repairs.
For example, a part may be covered at $0, but installation labour may cost $300–$1,500+.
Without labour coverage, homeowners still pay significant out-of-pocket costs even with a “10-year warranty.”
Key Takeaway
An HVAC warranty in Alberta usually means: “We cover the part, not the full repair.”
Understanding this difference is essential when comparing contractors and equipment packages.
