Repair of a Goodman wall-mounted heat pump in Outremont

An AirGreen intervention on a restricted but effective installation

At AirGreen , we are often called upon to work in urban residential settings where space for outdoor installation is limited. This was precisely the case during this repair of a Goodman wall-mounted heat pump in a building in Outremont , a neighborhood where balconies and side passages are often narrow, requiring exemplary rigor in installation and maintenance.

Context of the service call

The customer contacted us after noticing a decrease in the heating and cooling performance of their Goodman wall-mounted heat pump. Although the indoor unit appeared to be working, the air blown was lukewarm, and the room temperature was no longer stabilizing properly.

This type of symptom is common in urban environments where outdoor units, often installed on enclosed or semi-enclosed balconies , suffer from a lack of adequate ventilation . This restriction can affect compressor performance and cause the system to overheat.

Initial diagnosis

Our certified technicians carried out a complete inspection of the system:

  • Check refrigerant pressure and compressor start cycles.

  • Control of clearance space around the unit, essential for good heat dissipation.

  • Observation of fan behavior and air inlet/outlet temperatures.

The diagnosis quickly confirmed fouling of the external heat exchanger , combined with a partial obstruction of the condensation drain . These two factors limited the performance of the device and risked, in the long term, damaging the compressor.

Steps of repair

  1. Complete cleaning of the condenser coil : Application of a biodegradable cleaner designed to remove dust and deposits without damaging the fins.

  2. Clearing the condensation drain to ensure free flow of residual water.

  3. Inspection of refrigeration connections to detect any micro-leaks.

  4. Checking the operation of the fan and the control board .

  5. Full performance test after reboot.

Once the system was restarted, temperatures quickly returned to normal efficiency: the cold air outlet reached 7.2°C , confirming the full performance of the thermodynamic cycle.

Results obtained

The customer immediately noticed an improvement in interior comfort and a reduction in operating noise . The compressor, which is less stressed, will now consume less energy to reach the same temperature, extending the life of the system.

Special feature of the installation

The Goodman outdoor unit was installed on a metal anti-vibration base , positioned along a brick wall. This type of configuration, common in Montreal duplexes and triplexes, requires meticulous maintenance:

  • The minimum space of 30 cm around the unit must be respected.

  • The airflow must not be blocked by walls or railings.

  • Bi-annual cleaning is recommended to maintain optimal performance.

Our technicians also took care to slightly reposition the unit , optimizing airflow while reducing sound resonance on the facade.
