Custom HVAC expertise to bring comfort, efficiency, and value back to older buildings
In the city of Laval, many residential buildings constructed between the 1960s and 1980s still offer strong potential for comfortable living. However, their original configuration no longer meets today’s thermal comfort standards. Outdated insulation, lack of mechanical ventilation, poorly sealed windows—all of these factors reduce occupant well-being and significantly increase electricity bills. At AirGreen, we’re frequently called on to modernize these older apartments using perfectly adapted HVAC air conditioning solutions, without altering the building’s architecture or inflating renovation costs.
Unique challenges posed by older apartments in Laval
1. Structural constraints and limited space
In many older units, space for installing a wall-mounted heat pump or an outdoor condenser unit is very limited. Load-bearing walls are thicker, ceilings are lower, and the electrical systems are often outdated. Every project demands a custom technical assessment.
2. No existing HVAC infrastructure
Many of these apartments were never designed to accommodate air conditioning systems. It’s therefore essential to discreetly integrate ducts, wiring, and units without affecting aesthetics or structural integrity.
3. Compliance with municipal and co-ownership regulations
In Laval, many condo associations enforce strict rules about the look of façades and outdoor equipment. Our team handles all permit applications, technical sketches, and ensures full compliance with urban planning regulations.
Real-life examples of successful AirGreen installations in Laval
5½ unit transformation in Chomedey with a Gree Lomo R32 12,000 BTU wall-mounted heat pump
In this third-floor apartment from 1974, we installed a Gree Lomo wall-mounted indoor unit—compact, sleek, and efficient. The outdoor unit was discreetly placed in the backyard through a secondary balcony. The result: a 32% reduction in annual electricity costs and steady thermal comfort year-round.
Duplex optimization in Laval-des-Rapides with a Fujitsu Aquila R32 multi-zone system
The client’s goal: cool three separate rooms (living room, master bedroom, home office) without sacrificing wall space. We installed a 24,000 BTU multi-zone wall-mounted heat pump, with three ultra-quiet Fujitsu indoor units. Each zone is independently controlled, delivering significant energy savings.
Renovation of a rental unit with a LENNOX MFMD 9,000 BTU floor console
In a basement apartment, we opted for a floor-mounted console to avoid impacting already damaged exterior walls. The LENNOX model proved ideal for the small space and improved ambient humidity levels thanks to its efficient dehumidification mode.

Common mistakes to avoid in older apartments
1. Installing a unit that’s too powerful or too weak
Choosing a model without a proper thermal load calculation leads to overconsumption or constant discomfort. We use specialized software to evaluate the thermal load of each room.
2. Failing to check wall structure before drilling
Some old walls contain fragile materials (plaster, hollow brick). Poorly planned mounting can cause cracks or water infiltration. Our technicians use specialized anchors and reinforcements suited to each material.
3. Poor condensate management
Improper drainage can lead to water damage in walls or floors. We always install a secure drainage system with a lift pump if needed.
