The goods you buy to complete renovation work are covered by legal warranties. These warranties automatically apply without charge, even if the merchant or the manufacturer claims to sell without warranties. Among these warranties are :

  • the use warranty;
  • the reasonable lifetime warranty;
  • the warranty against hidden defects.

Warranties provided by the law: your rights

Legal warranties allow you to expect that the heating or air conditioning appliance you are buying :

  • will serve the purpose for which they were bought;
  • will have a reasonable lifetime, given the price paid, the contract, and the conditions of use;
  • will not contain hidden defects––that is, important defects that were present before the sale, but that were not mentioned to you and that you could not have noticed, even if you were observant;
  • will conform to the description written in the contract and the advertising, and to the merchant’s statements.

You also benefit from the same conditions on a second-hand appliance purchased from a merchant. In such cases, the fact that the appliance is used and its wear at the time of purchase must be taken into consideration.

What is a “reasonable lifetime”?

The reasonable lifetime warranty provides that a product must serve for normal use for a reasonable period of time. However, the law does not prescribe, for example, that an air conditioning appliance must have a lifetime of 10 years. Why? Because several factors must be taken into account to determine the reasonable lifetime of products. Those factors include the price paid, the contract's details, and the conditions of use. Thus, an air conditioning appliance worth $200 cannot be expected to last as long as would another appliance with the same features but that cost $600.

In short, it’s a question of facts and common sense.

How to assert your rights

If the heating or air conditioning appliance you had installed cannot serve its purpose, inform the merchant (and manufacturer, if applicable) of the problem. They will need to :

  • repair the materials or have it repaired without charge;
  • exchange it;
  • refund your money

You may also have suffered damages from using a defective product. If that is the case, the merchant may also have to compensate you.

Tools made available by the Office

To help you resolve your problem, the Office has made various tools available to you. First, refer to the Resolve a problem with a merchant section, which presents the various steps to follow. Among other things, you will find suggestions on negotiating with a merchant in order to reach an agreement.

The Office also makes available information kits tailored to problems of an exclusively civil nature. They cover reasonable durability of goods, deliveries and non-conformity of goods or services. The Download an information kit page provides all the information you need.

Need reference points?

Thanks to a partnership with the Société québécoise d’information juridique (SOQUIJ), the Office publishes summaries of the most recent judgments that deal with legal warranties, in particular those rendered by the small claims court. These summaries may be used to help support your efforts in asserting your rights with a merchant.
