Case study: real installations by AirGreen
Laval – Nguyen Family: Stable Heat, Reduced Bills
In December 2024, we installed a Zephyr 4-Ton in a single-story house in Laval. Within the first month of use, the family noticed a 28% reduction in their electricity bill compared to their previous dual-energy system.
“The control is intuitive, the comfort is consistent, and AirGreen’s service has been impeccable.” – Ms. Thi, Laval
Boucherville – Energy-efficient renovation project
As part of a major renovation project, a Boucherville family opted for this heat pump to replace an old oil-fired central system . The space was adapted to accommodate the new AH-648A indoor unit. Thanks to ENERGY STAR® certification, consumption has dropped dramatically.
“We took advantage of the LogisVert grant to reinvest in roof insulation.” – Julie P., Boucherville
