Elios central heat pump installed in Laval-des-Rapides
Installation of an Elios central heat pump in Laval-des-Rapides: a carefully designed residential basement project, optimized for comfort, energy efficiency and Quebec winters.
Take a tour of the installation
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
In summer, the outdoor unit rejects the house's heat outside.

It captures or rejects heat outside. It sits on a level base, above the snow, with free space all around.
The insulated refrigerant lines enter the house through a sealed opening and run to the indoor coil.
A shut-off switch near the outdoor unit isolates it safely for service.
Sitting on the indoor module, it moves heat between the house air and the refrigerant.
Electric furnace or air handler: its fan pushes air through the ducts. The electric backup takes over in extreme cold.
Supply ducts bring air to the rooms; returns bring it back to the unit. Their condition matters as much as the unit's.
It protects the coil and the fan. A dirty filter cuts airflow, so it gets checked regularly.
It runs the heat pump and the backup heat. It must be compatible with the installed system.
In this single-family home in Laval-des-Rapides , our AirGreen team completed the installation of an Elios central heat pump , integrated into an existing ductwork system in the basement. This type of project is very representative of Laval homes built with a dedicated mechanical room, offering excellent potential for conversion to a modern, high-performance, and energy-efficient heating and cooling solution.
An Elios central heat pump adapted for Quebec residential use
The Elios central heat pump installed here belongs to the new generation residential line, designed to operate efficiently in Quebec's climate. Combined with an indoor air management system and a ducted ductwork system, it provides uniform heating and cooling for the entire house, without any visible units in the rooms.
Even if the exact model is not explicitly identifiable visually, the configuration corresponds to a high-efficiency Elios central heat pump , compatible with standard forced-air residential installations, which are very common in Laval.
Context and constraints of the construction site in Laval-des-Rapides
The basement had several features typical of houses in the area:
-
Mechanical room with an open structure and exposed joists
-
Existing network of metal ducts , requiring precise adaptation of the plenum
-
Limited height necessitates a compact and well-planned integration.
-
The presence of wiring and plumbing requires rigorous coordination.
Our technicians installed the Elios indoor unit directly onto an insulated base, with careful connection to the main ductwork. The joints were fully sealed with aluminum tape and sealant , ensuring optimal airtightness and minimizing air leakage.
Prominent installation details observable
From the photo and the context, several technical elements clearly stand out:
-
Elios central air handling unit installed vertically in the basement
-
Custom-made plenum , adjusted to existing ducts
-
Enhanced insulation and sealing of duct transitions
-
Neat routing of lines and cables , properly fixed to the joists
-
Clear access for future maintenance , an often overlooked point
This attention to detail is part of our AirGreen approach: every installation must not only be efficient, but also durable and easy to maintain.
Why choose an Elios central heat pump in Laval?
For a house like this one in Laval-des-Rapides, the Elios central heat pump offers several concrete advantages:
-
Uniform comfort in all rooms
-
Excellent heating and air conditioning performance
-
Reduced energy costs compared to older systems
-
Compatibility with provincial and federal subsidies (subject to eligibility)
-
No visible wall unit , for a clean interior
This is an ideal solution for families looking to modernize their system without altering the aesthetics of their living spaces.
An installation designed for the Quebec winter
In Laval, winters are demanding. We have therefore configured the Elios system to ensure:
-
Stable heating capacity even in cold weather
-
A balanced air distribution , avoiding cold spots
-
Long-term reliability , thanks to an installation that complies with best HVAC practices
Every connection, every seal and every adjustment is designed to maximize the system's performance over several years.
The AirGreen approach: local expertise and technical rigor
At AirGreen, we work daily in Laval, Montreal, on the North Shore and the South Shore . This proximity allows us to understand the realities of local buildings: varying ceiling heights, compact mechanical rooms, and ductwork systems that are old or have been modified over time.
For this project in Laval-des-Rapides, our priority was clear: to deliver a clean, efficient installation perfectly suited to the home , without compromising on quality.

The big day, step by step
The main steps of this kind of job at AirGreen. Every house has its quirks: the estimate brings them out.
We look at the ducts, the current indoor module, the electrical panel and the planned spot for the outdoor unit.
The equipment combination, capacity and price, in writing. We check whether the combination qualifies for assistance programs.
Access protected, old unit disconnected and removed when it is being replaced.
Electric furnace or air handler, with its coil, connected to the supply and return ducts.
On a level base, raised above the snow, with free space all around.
Insulated, they enter through a sealed opening and run to the indoor coil.
Dedicated circuits, accessible disconnect, a thermostat that works with the heat pump and the backup heat.
Leak test, vacuum, start-up, airflow check and a test of both modes.

What would it look like at your place?
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.

Your own project, step by step
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
- Check the indoor module's filter.
- Clear winter debris from the outdoor unit.
- Test cooling before the heat arrives.
- Check the filter more often in peak season.
- Keep registers and returns clear.
- Watch condensate drainage near the coil.
- Change or clean the filter.
- Test heating and backup heat before the cold.
- Book periodic maintenance.
- Clear snow around the outdoor unit.
- Store nothing in front of the indoor module.
- Note any unusual noise or smell and call us.
Is your home ready?
Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.
Four statements: true or false?
It all comes down to details you have just seen.
1. A central heat pump uses the house's ducts.
It connects to the existing ducts to heat and cool everywhere.
2. In extreme cold, electric backup heat can take over.
The indoor module (furnace or air handler) works with the heat pump and takes over in extreme cold.
3. The filter only gets changed when the unit breaks down.
A dirty filter cuts airflow. It gets checked regularly.
4. You can reuse the old unit's size without checking.
The house may have changed: insulation, windows, added rooms. Capacity is confirmed on site.
