A rooftop installation that demonstrates the importance of an HVAC approach adapted to Quebec buildings
At AirGreen, we install wall-mounted heat pumps in a wide variety of environments: single-family homes, condos, multi-unit buildings, and buildings with particular architectural constraints. The installation completed in Saint-Télesphore perfectly illustrates a situation where the available space requires a different approach from a traditional residential installation.
For this project, our team installed a ForestAir E24 wall-mounted heat pump with the outdoor unit positioned on a flat roof. This configuration requires special attention, as the outdoor unit must be protected against vibrations, snow accumulation, the elements, and the specific constraints of rooftop installations.
The photo of this installation shows a professional approach, with the ForestAir outdoor unit installed on an elevated structure to maintain adequate clearance beneath the unit. This method promotes better drainage of water from defrost cycles and limits the risks associated with ice accumulation during the winter.
A ForestAir E24 heat pump designed for the climate of Saint-Télesphore
A heating and cooling solution adapted to residential needs
The ForestAir E24 installed by AirGreen is a 12,000 BTU/h inverter wall-mounted heat pump designed to provide four-season comfort.
In regions such as Saint-Télesphore, where temperatures can vary greatly between hot summer days and cold winter periods, a high-efficiency heat pump is an appealing solution for improving indoor comfort.
Unlike a simple wall-mounted air conditioner, a heat pump allows you to:
- To provide effective cooling during the summer;
- To provide additional heating during the cold seasons;
- To reduce the use of electric baseboards when conditions are favorable;
- To improve indoor temperature consistency.
Thanks to inverter technology, the compressor automatically adjusts its power according to the building’s actual needs. This allows the system to avoid the frequent starts of a traditional unit and operate more steadily.
Technical features of the ForestAir E24
The installed model has several features sought after for a residential installation in Quebec:
- Brand: ForestAir
- Model: E24
- Type: inverter wall-mounted heat pump
- Capacity: 12,000 BTU/h
- Refrigerant: R-454B
- Energy efficiency: up to approximately 24 SEER
- Heating operation down to approximately -25 °C
The choice of model is not based solely on capacity. At AirGreen, we analyze the entire building to recommend a unit that truly meets the homeowner’s needs.
A properly sized heat pump provides:
- Improved energy efficiency;
- More consistent comfort;
- Reduced compressor wear;
- Quieter operation.
A unique rooftop installation in Saint-Télesphore
Why install an outdoor unit on a roof?
In many residential projects, the outdoor unit is installed on the ground or mounted on an exterior wall. However, some properties have constraints that make a rooftop installation more suitable.
In this installation in Saint-Télesphore, the ForestAir E24 outdoor unit was placed on a raised metal structure.
This configuration offers several advantages:
- Protection against significant snow accumulation;
- Improved airflow around the condenser;
- More efficient drainage of defrost water;
- Reduced risk of freezing around the unit.
However, a rooftop installation must be carried out with particular care. An improper installation method can transmit vibrations to the building structure or make future maintenance more difficult.
At AirGreen, we always consider:
- The strength of the existing structure;
- Support stability;
- Protection of the roofing membrane;
- Safe access for maintenance;
- The necessary clearance around the unit.
Vibration management and roof protection
Vibrations are an important consideration when a heat pump is installed on a roof.
The compressor and outdoor fan naturally generate some vibrations during operation. If the installation is not carried out properly, these vibrations may be transmitted to the building.
To limit this phenomenon, several factors must be taken into consideration:
- Use of a suitable support;
- Installation of vibration-reducing materials;
- Stable unit positioning;
- Checking the system alignment.
The photo of this installation also shows a raised base that keeps the outdoor unit away from the roof surface while ensuring a stable installation.
The benefits of a ForestAir E24 wall-mounted heat pump for Quebec homeowners
Effective air conditioning during hot weather
During periods of summer heat, homes in Saint-Télesphore and the surrounding areas can quickly accumulate heat, particularly in rooms exposed to sunlight.
A wall-mounted heat pump such as the ForestAir E24 helps maintain a more comfortable indoor temperature through:
- Intelligent compressor modulation;
- Uniform air distribution;
- Quiet operation;
- Better humidity management.
Comfort does not depend solely on the temperature displayed on the thermostat. Good air circulation and a stable temperature also play an important role.
Efficient heating during the fall and part of the winter
In Quebec, a heat pump can become an excellent source of supplemental heating.
During fall days or milder winter periods, it often allows certain areas of the home to be heated efficiently while limiting the use of traditional electric systems.
This approach allows homeowners to better manage their energy consumption without compromising their comfort.
Mistakes to avoid when installing a wall-mounted heat pump
Neglecting the location of the outdoor unit
The location of the outdoor condenser directly affects system performance.
Avoid:
- Spaces that are too enclosed;
- Areas where snow blocks the air intakes;
- Locations without maintenance access;
- Unstable installations.
An outdoor unit must be able to breathe freely to efficiently release heat in cooling mode and recover outdoor energy in heating mode.
Underestimating the importance of HVAC maintenance
Even a high-performance heat pump requires regular maintenance.
At AirGreen, we recommend:
- Regular cleaning of indoor filters;
- Verification of system performance;
- Professional cleaning of the indoor unit when necessary;
- Inspection of the outdoor unit before the cold season.
Regular HVAC maintenance helps maintain:
- Energy efficiency;
- Indoor air quality;
- System reliability;
- The equipment’s lifespan.
