A critical HVAC installation at a decisive moment
At AirGreen, we’re used to responding quickly and efficiently to our clients’ needs—but some projects leave a lasting mark. That was the case with this multizone heat pump installation in Longueuil, carried out under truly unique circumstances. Just days before Christmas, a family contacted us in a panic: their old central heating system had just failed, threatening to ruin their holiday and leave them in the cold.
Thanks to our responsiveness, the expertise of our team, and the swift installation of a high-performance Gree Multi+ multizone heat pump, we not only restored their heating in time but also provided the family with a long-term, energy-efficient, and elegant solution for the years ahead.
The emergency in Longueuil: a home with no heat right before Christmas
The call came in on a freezing Thursday evening in December. The client, owner of a single-family home in a quiet residential area of Longueuil, explained that their old oil-based central system had just irreversibly failed. The temperature was hovering around -15 °C, and with two young children in the house, immediate action was needed.
The very next morning, our team was on-site for a full evaluation. Given the urgency and tight timeline, we proposed a turnkey HVAC solution: the installation of a Gree Multi+ multizone heat pump with three 12,000 BTU wall-mounted indoor units strategically placed throughout the home.
Why the Gree multizone heat pump was the best option
The Gree Multi+ multizone heat pump stood out as the ideal choice for this home:
-
High heating capacity down to -30 °C, perfect for harsh Quebec winters.
-
Multizone system: three independent wall-mounted units allow precise temperature control in each living space.
-
Significant energy savings: with a seasonal energy efficiency ratio (SEER) over 21, this heat pump qualifies for Hydro-Québec’s LogisVert rebates, up to $5,000 in some cases.
-
Modern and discreet design of the indoor wall units, seamlessly blending into the home’s decor.
Technical challenges on-site
Installing a full system in such a short timeframe—especially right before the holidays—posed a real logistical challenge. Here are the key steps that our team managed expertly:
-
Removal of the old central system: safely disconnecting and securing the existing ductwork and outdated components.
-
Optimal positioning of the wall-mounted units: in the living room, master bedroom, and family room.
-
Installation of a 36,000 BTU outdoor compressor, requiring a reinforced wall bracket and a location clear of snow buildup.
-
Discreet routing of refrigerant lines through existing walls without damaging interior finishes.
-
Full system testing and client training on how to use the individual remotes and smart features.
A warm home just in time for Christmas Eve
The entire job was completed in just 48 hours, a feat made possible thanks to the perfect coordination between our technicians, warehouse logistics, and our fully mobilized team. On Sunday morning—Christmas Eve—the system was fully operational. The children woke up in a warm, cozy house, and the parents were able to welcome their family as planned.
Client testimonial: “AirGreen saved our Christmas!”
"We were completely desperate. We thought we’d have to rent temporary heaters just to survive the holidays in the cold. But AirGreen responded immediately, and their team installed everything with care and professionalism. The house is more comfortable than ever. Thank you from the bottom of our hearts!"
Rebates and long-term savings: a smart investment
Thanks to this installation, the homeowners were able to benefit from the Hydro-Québec LogisVert rebate, which reimbursed a substantial portion of the cost. On top of that, the system now allows them to reduce their heating bills by 30 to 40% every month while enjoying year-round comfort.
