The rule
The air conditioner is named in s. 38.1 and its warranty lasts 6 years under the regulation. It comes on top of the manufacturer's warranty: when that one ends, the legal warranty continues.
Examples of covered breakdowns
- The unit blows air but no longer cools (compressor).
- The fan or the motor stops working.
- The remote works, but the unit no longer responds (control board).
What isn't covered
- Cleaning or replacing the filter (s. 38.3).
- Damage caused by a fall or by an installation that goes against the instructions.
- Accessories, like the remote or the window kit, unless they're provided for by regulation.
Air conditioner or heat pump? A wall unit that cools and heats is usually a heat pump. The length is the same: 6 years.
It broke: the steps

- Choose who to contact: the merchant, the manufacturer, or both. Neither one can send you to the other.

Frequently asked questions
My air conditioner only runs in the summer. Is the warranty extended?
No. The 6 years run from delivery, no matter how many months a year you use it.
Do I have to pay to ship my portable air conditioner for repair?
No. Reasonable transport or shipping costs are paid by the merchant or the manufacturer (s. 38.5).
