Repair of an Elios wall-mounted heat pump in Saint-Laurent

When too high an air temperature reveals a performance problem

At AirGreen , every service call is an opportunity to give our customers the comfort they deserve, while ensuring optimal performance of their HVAC system. Recently, our team intervened in Saint-Laurent , in a modern condo equipped with an Elios wall-mounted heat pump . The customer contacted us after noticing that the unit, while functional, was no longer effectively cooling their living space.

Using an infrared thermometer , our technician confirmed that the blown air was at 11.2°C , a temperature insufficient for a normal air conditioning cycle. A thorough inspection was required.

Diagnosis: lack of maintenance and fouling of the coil

Our specialists immediately opened the front panel of the wall unit to inspect:

  • The air filter (clogged and clogged with dust),

  • The evaporator coil (clogged by a slight deposit),

  • The tangential fan (slowed down by the accumulation of dirt),

  • And the electronic card , often affected by humidity or electrical fluctuations.

The analysis revealed a twofold problem:

  1. Neglected maintenance , which limited the air flow.

  2. A slight loss of refrigerant efficiency , probably due to a micro-leak at the flare connection.

This type of failure is typical of residential installations that have not received complete annual maintenance , a crucial step in maintaining performance and extending the life of the heat pump.

The intervention: cleaning, checking and recharging

Our technician undertook a complete three-step procedure:

1. Cleaning and restoring airflow

  • Disassembly and complete cleaning of the filters with warm water and mild soap.

  • Applying a specialized degreaser to the coil to dissolve greasy deposits.

  • Low pressure rinse to preserve the aluminum fins.

  • Cleaning the tangential fan and the condensate gutter .

2. Checking the refrigeration circuit

  • Static pressure test of the system.

  • Leak detection using an electronic tracer .

  • Tightening of flare fittings and controlled tightening with a torque wrench.

3. Recharge and final test

  • Recharge of R-32 refrigerant according to Elios specifications.

  • Power on and performance check: the blown air reached 6.7°C , confirming a return to normal.

  • Observation of a difference of 12°C between ambient air and blown air, guaranteeing optimal performance.

Results and advice to the client

The customer immediately noticed the difference: in less than 15 minutes, the room temperature dropped to a comfortable level.
We took the time to explain:

  • The importance of cleaning the filters every two months during the summer season,

  • The benefits of professional annual maintenance (prevention of micro-leaks, calibration of the temperature sensor, cleaning of the coils),

  • And the recommendation of an AirGreen maintenance contract , which includes preventive monitoring before each heating and cooling season.
