Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
A discreet and aesthetic air conditioning solution for a condo in Laval
At AirGreen , we recently completed the installation of a GoldStar wall-mounted air conditioner in a condo in the Laval-des-Rapides neighborhood. This installation perfectly illustrates how to combine comfort, aesthetics, and energy efficiency, even in small interior spaces.
The client's request was clear: to obtain efficient air conditioning for his condo, while integrating the unit discreetly into the interior decor.
Project background
The owner of a modern condo in Laval-des-Rapides was suffering from excessive heat in the summer. He was looking for an air conditioning solution that:
-
takes up little space,

ensures quiet operation,
-
and helps maintain a neat atmosphere inside.
The GoldStar wall-mounted air conditioner met these expectations brilliantly. This compact unit is designed to deliver efficient cooling performance without the need for intrusive ductwork.

The unit was installed high on a side wall, above a decorative painting.
-
Its minimalist white design blends harmoniously with the aesthetics of the condo.
-
The location was chosen to maximize air circulation in the main room.
Passage of conduits
Our technicians have carefully planned the route of the refrigeration connections :
-
Minimalist drilling of the exterior wall, respecting the existing insulation.
-
Insulated and protected ducts to prevent any loss of energy efficiency.
-
Condensation drain directed towards the outside, by gravity, to ensure constant flow and avoid any accumulation of water.
Particularities of the site
-
The ceiling height and wall space configuration required precise adjustments to avoid encroaching on the decorative elements.

The work was completed in half a day, allowing the customer to immediately benefit from the comfort of fresh, even air.

And 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.
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
