How Long Do You Depreciate HVAC in Canada? | CCA Guide 2025

So, you’re asking: “How long does it take to depreciate an HVAC system in Canada?”

Here’s the truth: Unlike the U.S., Canada doesn’t assign HVAC a fixed year schedule. Instead, the Canada Revenue Agency (CRA) uses Capital Cost Allowance (CCA) classes, each with its own depreciation rate.

HVAC Depreciation by Class (CCA)

Class 1 — Permanent HVAC in Buildings
- Treated as part of the building.
- Depreciated at 4% declining balance.
- Applies to most residential and commercial installations.
Class 13 — Leasehold Improvements
- HVAC upgrades in rented properties.
- Straight-line depreciation over the lease term (max 40 years).
Class 8 — Portable HVAC Equipment
- Movable/temporary units.
- Depreciated at 20% declining balance.
Class 43.1 / 43.2 — Energy-Efficient HVAC
- High-efficiency or renewable-energy systems may qualify here.
- Accelerated depreciation rates of 30%–50%.

How Long It Really Takes

Standard HVAC systems in buildings (Class 1) often take decades to fully depreciate due to the 4% rate.
Leasehold improvements depend on lease length (but capped at 40 years).
Green HVAC systems can be written off much faster thanks to Clean Energy Classes.

✅ Bottom Line: In Canada, you don’t depreciate HVAC over a fixed 5, 10, or 15 years. Instead, it depends on the CCA class: 4% for permanent installs, 20% for portable units, and faster rates for energy-efficient upgrades.
