An AirGreen intervention on an urban balcony: efficiency and precision
Recently, our AirGreen team was called for HVAC repair service in a condo located in Saint-Lambert , on Montreal's South Shore . The client contacted us after noticing that their BÉco wall-mounted heat pump was no longer producing enough heat, despite an external compressor that appeared to be working. The unit, installed on a small glass balcony, represented a typical case of deferred maintenance in a confined space.
Initial diagnosis: a functional compressor, but reduced performance
Upon our arrival, our technicians noted several worrying elements:
-
The condenser grille was covered with a thin layer of dust and debris.
-
The airflow was partially obstructed by objects placed too close to the unit (chair, plant and various accessories).
-
The condensate drain was showing signs of blockage, causing water to accumulate under the indoor unit.
We carried out a complete diagnosis using our measuring instruments:
-
Refrigerant gas pressure (R-410A) checked: slightly lower than standard.
-
Compressor discharge temperature: abnormally high.
-
Indoor airflow: insufficient, due to coil fouling.
These signs indicated a drop in energy efficiency linked to a lack of regular maintenance and an accumulation of dust on the exchangers .
Repair steps: cleaning, readjustment and releveling
1. Complete cleaning of the condenser
We began by removing debris and dust that had accumulated on the surface of the outdoor condenser. A gentle spray of a biodegradable cleaner restored optimal airflow. Since the unit was located on a partially enclosed balcony, we were careful to use low-odor products with no harmful emissions.
2. Checking and repairing drainage
The condensate drain pipe had a slight dust plug. We purged and repositioned it to prevent water from backing up into the indoor unit.
3. Readjustment of the refrigerant charge
A small, slow leak had likely caused the R-410A pressure to drop . After electronic detection and tightening the main fitting, we added the exact amount needed to reach the nominal pressure recommended by the BÉco manufacturer.
4. Final performance test
Once the interventions were completed, we carried out:
-
A blowing temperature test : 12°C difference between incoming and outgoing air (optimal result).
-
An electrical intensity test : stable and compliant.
-
A noise and vibration inspection : no anomalies.
Result: comfort restored and prevention assured
Thanks to this intervention, the client's BÉco wall-mounted heat pump is now operating at full capacity, providing even and quiet heating throughout the condo. We recommended that the client:
-
Free up space around the compressor to improve ventilation.
-
Schedule annual preventative maintenance before each winter.
-
Clean the indoor unit filters regularly.
This visit perfectly illustrates the importance of regular HVAC maintenance , especially in urban housing where installations are often compact and exposed to dust or humidity.

What this intervention reminds us of
Urban balconies and glass terraces are becoming increasingly common in new construction. However, they present specific challenges:
-
Limited air circulation around the condenser.
-
Accumulation of dust and moisture .
-
Increased risk of overheating in summer and freezing in winter .
Our team always recommends checking:
-
Free space around the unit (minimum 30 cm on each side).

The stability of the mounting brackets .
-
The absence of obstacles to ventilation (plants, chairs, decorative objects).
