A Little-Known Strategy to Improve Comfort and Cut Your Heating Costs in Longueuil
At AirGreen, we know that most homeowners in Longueuil, on the South Shore, don’t immediately think of their attic when it comes to energy performance. And yet, a poorly insulated or unheated attic can be responsible for up to 30% of a home’s heat loss. Properly heating this strategic space can have a direct and dramatic impact on your energy consumption, while also improving the overall comfort of your home.
The Attic: A Critical Zone in Your Home’s Thermal Envelope
In winter, warm air from your central heating system naturally rises. If it reaches a cold or poorly insulated attic, it quickly dissipates, which forces your HVAC system to run longer. This results in:
-
Overuse of your heat pump or furnace
-
Higher energy bills
-
Uneven comfort across floors
Heating the attic means stabilizing indoor temperature, relieving your main system, and reducing heat loss through the roof.
A Well-Designed HVAC Installation, Tailored for Attics
We recently completed an installation in Longueuil in a century-old home where the attic was partially finished but completely unheated. The client complained of drafts, excessive energy use, and persistent cold spots on the ground floor.
Our team installed a FUJITSU KZAH R-32 wall-mounted heat pump | 9,000 BTU, perfectly suited to the space’s layout. Why this model?
-
Its low electrical consumption, ideal for a small volume
-
Its ultra-quiet operation, essential for semi-living areas
-
Its optimal low-temperature performance, critical for an exposed attic
Post-Installation Results: Performance and Savings
Three weeks after commissioning, the client confirmed:
-
A more stable indoor temperature throughout the house
-
A nearly 40% reduction in run-time for the main heat pump
-
A first monthly bill 48% lower than the same period last year
In addition, the installation qualified for a $1,704 LogisVert grant, significantly reducing the total project cost.
Technical Tips: How to Heat Your Attic Effectively
Step 1: Evaluate Existing Insulation
Before any installation, our team always performs:
-
A check of ceiling and wall insulation in the attic
-
An airflow and thermal bridge analysis
-
An infiltration test to detect invisible losses
Step 2: Choose the Right Unit
Small-capacity models between 6,000 and 12,000 BTU are often enough to heat an attic. We recommend brands such as:
-
Fujitsu for their reliability and quiet operation
-
Gree Charmo R32 for their excellent value
-
Midea EVOX G3 for homes integrated with a central system
Step 3: Professional Installation by AirGreen
We provide:
-
A wall-mounted setup with no impact on roof structure
-
Secure electrical connections
-
An optimized configuration for even heat distribution
Heating the Attic: Who Should Consider It?
Homeowners with Attic Bedrooms or Office Spaces
Older homes in Longueuil and the South Shore often have upper floors converted into bedrooms or offices. In these cases, heating the attic becomes essential for comfort.
Families Looking to Cut Consumption
If your Hydro-Québec bill spikes in the winter, it may be because your main system is compensating for thermal imbalance. Adding a secondary heating unit in the attic helps split the heating load, thus lowering consumption.
Renovation or Expansion Projects
When converting attic space into living space, it’s crucial to plan for the right HVAC system. AirGreen supports you from assessment to installation, using the best energy-efficient products eligible for grants.
