Repair of a Toshiba Carrier wall-mounted heat pump in Sainte-Julie

An urgent service call for a broken Toshiba Carrier heat pump

At AirGreen , we were contacted by a customer living in Sainte-Julie , on the South Shore of Montreal , who was concerned about the abnormal operation of his Toshiba Carrier Inverter wall-mounted heat pump . The outdoor unit, installed several years ago, was no longer producing adequate heat despite a constant heating demand. With the falling fall temperatures, the family's comfort was seriously compromised.

Initial inspection: symptoms observed

Upon our arrival on site, we noticed several telltale signs of a performance problem:

  • Outdoor fan operating intermittently

  • Accumulation of dirt and dust on the top of the condenser

  • Inefficient heat exchange , resulting in short cycles

  • Irregular noise from the compressor when starting up

These clues pointed our technicians towards a compressor or control board problem , typical of Toshiba Carrier Inverter models that are several years old.

In-depth diagnosis: AirGreen method

At AirGreen, each diagnosis is carried out according to a precise and rigorous procedure:

  1. Measurement of refrigerant pressures to check circuit integrity.

  2. Inspection of electrical connections and inverter module.

  3. Checking airflow and coil cleanliness.

  4. Analysis of communication between indoor and outdoor units (Toshiba Carrier protocol).

Result: The inverter control board was showing signs of intermittent failure. This caused the compressor to shut down before the end of the normal cycle, limiting heating capacity.

  • Complete replacement of the Inverter control board with a genuine Toshiba Carrier part.

  • Complete cleaning of the condenser with a biodegradable AirGreen ProClean product.
