A Custom Air Conditioning Solution to Reinvent Comfort in a Century-Old Home in Laval
At AirGreen, we firmly believe that every home—no matter its age or architectural style—deserves a smart, energy-efficient, and seamlessly integrated air conditioning solution. That was exactly our approach for this unique project in Laval, where a century-old house was entrusted to us by a couple looking to improve their quality of life without compromising the historic charm of their property. Thanks to meticulous planning, a thorough technical assessment, and the installation of a Gree Lomo 12,000 BTU wall-mounted air conditioner tailored to the specifics of the home, we successfully combined modern comfort with architectural preservation.
Initial Diagnosis: A Charming House but a Challenging One to Cool
This Laval home, dating back to the early 20th century, presented several challenges: thick uninsulated walls, no existing ductwork, high ceilings, and vintage windows that let in a lot of heat. The homeowners contacted us with a clear request: they wanted an efficient, quiet, discreet, and above all aesthetically respectful air conditioning solution.
After a full inspection, our experts in HVAC installation in Laval determined that the best approach would be a high-efficiency wall-mounted heat pump, installed to minimize visual impact while maximizing comfort.
Why Did We Choose the Gree Lomo 12,000 BTU?
Choosing the Gree Lomo 12,000 BTU model was no accident. This wall-mounted unit stands out thanks to:
-
Its compact size, ideal for discreet integration into a classically designed home.
-
Ultra-quiet operation, perfect for bedrooms and calm living spaces.
-
A high SEER (Seasonal Energy Efficiency Ratio), ensuring lower energy consumption.
-
Eligibility for Hydro-Québec's LogisVert grant program, a valuable financial incentive for homeowners.
In addition, its built-in Inverter technology automatically adjusts power levels to maintain thermal comfort at all times—whether during hot summer days or cooler fall evenings in Laval.
Key Installation Steps in a Delicate Environment
Installing a wall-mounted air conditioner in a heritage home takes more than just technical know-how. You must respect the building’s integrity, its original materials, and structural nuances. Here’s the process we followed:
Step 1: Thermal Assessment and Structural Study
Our technicians carried out a full thermal analysis, measuring heat loss, airflow, and sun exposure. We also examined the exterior walls to determine the ideal location for the indoor unit—without drilling into historical elements.
Step 2: Custom Planning
For this project, we developed a custom installation plan that included:
-
A discreetly routed drain line to the outside.
-
A dedicated electrical circuit to avoid overloading the existing panel.
-
Installation of the outdoor unit on a wall-mounted, anti-vibration bracket, placed in a shaded garden corner to boost performance and prolong the unit’s lifespan.
Step 3: Careful Installation and Performance Testing
The indoor unit was installed in the living room, where the family spends most of their time. Thanks to our expertise in air conditioning in Laval, the installation was completed in a single day, with zero damage and a meticulous post-job cleanup. Tests confirmed optimal performance as soon as the unit was turned on.
The Result: Unmatched Comfort and Real Energy Savings
One week after the installation, the clients shared their satisfaction with us:
"We never thought an old house like ours could feel this comfortable. The temperature is steady, the air is clean, and most importantly, we’ve already reduced our energy usage in the first month. Thanks to the entire AirGreen team!"
This project in Laval is a perfect example of how we tailor our air conditioning services to the unique features of each home, while maximizing energy efficiency, aesthetic discretion, and everyday comfort.
Grant Eligibility and Financial Incentives
The installed wall-mounted air conditioner is eligible for a $650 grant through Hydro-Québec’s LogisVert program. We also supported the clients in preparing the required paperwork, simplifying the entire application process.
