The grant must be confirmed for the exact configuration and your home. Hydro-Québec pays the grant after approval. Asterisks in model numbers indicate the variants covered by the official list.
Amounts checked on September 25, 2026, excluding any additional incentives. For new construction, the amount must be checked separately. For a multi-zone system, the indoor-unit configuration must be verified before the grant can be confirmed.
