New HVAC System Installed Despite Winter Challenges
At AirGreen , we know that indoor comfort can't wait for the warmer weather. That's why our team recently completed the installation of a Midea wall-mounted heat pump in the middle of February, in Saint-Lambert , on the South Shore of Montreal .
Despite the heavy snow and freezing temperatures, our technicians ensured impeccable commissioning , fully compliant with RBQ and TEQ standards.
The context: a necessary replacement before the cold wave
The owner contacted us after his old wall-mounted air conditioner stopped working in mid-January. Wanting a versatile and energy-efficient solution, he opted for a Midea Inverter heat pump , a model renowned for its consistent performance down to -25°C .
Our mission: to dismantle the old system and install the new one in a single day , before the temperature drop expected the following night.
Preparation and logistics on a winter construction site
Winter installation requires meticulous planning . The outdoor area first had to be cleared of snow and stabilized to accommodate the new unit's anti-vibration base.
Our technicians then:
-
Checked the minimum distance to the ground to avoid ice accumulation around the condenser;
-
Positioned the new wall bracket at a height adapted to the topography of the land;
-
Inspected the existing electrical outlet and replaced the outdoor switch with a CSA approved, freeze-resistant model.
These steps are crucial to ensure the security and durability of the system.
Technical installation of the Midea Inverter heat pump
The Midea wall-mounted heat pump installed was a 12,000 BTU model, perfectly suited to the size of the ground floor of the residence.
Here is the precise progress of the work:
-
Fixing the interior wall bracket with reinforcements at the anchor points.
-
Refrigeration piping and reinforced thermal insulation with waterproof tape to prevent infiltration.
-
Installation of the outdoor condenser , carefully leveled on a moisture-resistant composite base.
-
Connection of the refrigeration lines and complete vacuuming of the circuit.
-
Nitrogen leak test to ensure stable pressure before recharging.
-
Commissioning and calibration of the inverter compressor according to Midea specifications.
Despite the temperature of -12°C, the vacuum was carried out perfectly, ensuring a circuit completely free of humidity .
Start-up and final check
Once the system was up and running, our technicians proceeded to:
-
Measurement of operating pressures in heating mode;
-
Checking the condensate drain to prevent future freezing;
-
The communication test between the indoor and outdoor modules.
Result: the heat pump delivered stable and quiet power , with an indoor blowing temperature of 41°C after only 5 minutes.
The client immediately noticed a soft and even heat in all the main rooms.
