The Transformation from Old to Gold
When it comes to HVAC installations, every project tells a story. Today, we're diving deep into one of our recent installations in Laval, where we transformed an outdated system into a state-of-the-art, energy-efficient marvel.
The Backstory
Our customer in Laval had been relying on an old system with a heat pump that sounded like a freight train and could only muster the strength to work until it hit -10°C outside. Couple that with an oil tank that took up a significant chunk of their basement, and you can imagine the inefficiencies and inconveniences they were dealing with. But as fate would have it, their old heat pump decided to retire, and that's when we stepped in.
Why the Tosot Apex Central Heat Pump?
-
Heating Capacity: With the ability to provide warmth even at a bone-chilling -30°C, the Tosot Apex is a beast in disguise.
-
Cooling Capacity: Boasting a cooling capacity of 60,000 BTU, it ensures that summers are as comfortable as winters are warm.
-
Efficiency: With a SEER of 17.5, HSPF of 11.0, and EER of 9.0, it's an epitome of efficiency.
-
Sound: Whisper quiet at 60.0 dB(A), it's a stark contrast to the old system our customer had.
-
Warranty: A solid 10-year warranty on the compressor and parts, with an extended warranty available.
-
Extras: WiFi included for those tech-savvy homeowners and an AHRI of 205724741.
The Installation Process
The installation was straightforward, thanks to the simplicity of the Tosot Apex model. But what made this project special was the transformation. We removed the old, noisy heat pump and the space-consuming oil tank. The result? A spacious basement and a home equipped with a heat pump that's not just efficient but also whisper quiet.
Federal Grant: A Cherry on Top
Our customer was not just thrilled with their new system but also the fact that they could take advantage of the $5,000 federal grant. Switching to full electric was not just an environmentally conscious decision but also a financially smart one.

Every installation we undertake is a commitment to excellence. From Laval to Longueuil, from the North Shore to the South Shore, we've been ensuring that our customers get the best, and this installation was no exception.
The job tools
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.
How the job unfolds
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.
Filter, thermostat, backup heat in extreme cold: what to know before winter.

What we check on a job like this one
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.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
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.

Good habits, once the unit is in place
Six simple habits that keep the unit going. Your list stays on this device.
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.
The right pages, at the right time
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.
