Repair of a TCL wall-mounted air conditioner in Sainte-Julie

A fast and accurate service call on the South Shore

At AirGreen , every service call is an opportunity to demonstrate our expertise in HVAC system repair . Recently, we were contacted by a customer in Sainte-Julie , on the South Shore of Montreal , whose TCL wall-mounted air conditioner was showing worrying signs: a distinct lack of cooling performance, accompanied by an unusual noise coming from the outdoor compressor .

Diagnosis: Compressor under tension and lack of refrigerant

Upon arrival at the site, our technician immediately noticed that the TCL compressor was operating erratically. The customer had attempted to restart the unit without success. After a thorough inspection, here are the main observations:

  • Abnormal refrigerant pressure , sign of a slow leak in the circuit .

  • Compressor vibration indicating internal imbalance possibly linked to a previous electrical overload .

  • Accumulation of dirt on the external exchanger , reducing thermal efficiency.

Using our electronic diagnostic tools , we confirmed that the leak came from a micro-cracked solder joint on the discharge pipe, a common problem on some residential units installed on the edge of balconies.

On-site repair: soldering, recharging and calibration

Once the diagnosis was confirmed, our team proceeded with the complete repair in three stages:

  1. Silver solder to seal the leak on the copper pipe.

  2. Nitrogen leak test to ensure no micro-leaks remained.

  3. Recharge the system with R-410A refrigerant according to TCL manufacturer's specifications.

To optimize performance, we then checked:

  • The rate of superheating and subcooling .

  • The indoor air flow .

  • The compressor's power consumption , confirming that it was now within the normal range.

Result: comfort restored and energy efficiency restored

At the end of the intervention, the TCL unit displayed new perfect operating pressures and restored cooling efficiency . The customer immediately noticed the difference: fresh and constant air, without excessive noise.

We also took the time to advise the client on:

  • Periodic cleaning of the outdoor condenser , especially on balconies.
