When the reliability of an old system meets the modern expertise of AirGreen
At AirGreen , we are regularly called upon to work on older generation units still in service in many residences in Greater Montreal. Recently, our team was called upon in Beaconsfield , on the West Shore of Montreal , to diagnose and repair a Sanyo wall-mounted air conditioner that was no longer adequately cooling a single-family home.
Initial diagnosis: a faithful, but tired device
The customer contacted us after noticing that the indoor unit of his Sanyo , a SAP-K1212 model, was no longer blowing cold air, despite a working outdoor compressor. Upon arrival on site, our technician carried out a series of checks:
-
Inspection of the air filter , which was found to be dirty.
-
Testing the electronic board and thermal sensors .
-
Checking the refrigerant pressure .
Quickly, the diagnosis revealed a communication problem between the indoor unit and the outdoor condenser , typical of Sanyo systems of this generation.
Intervention: precision and respect for the equipment
To resolve this outage, we have taken the following actions:
-
Complete cleaning of filters and evaporator to ensure good airflow.
-
Replacement of the communication cable connecting the two units, which had a damaged section.
-
Reset the control module and recalibrate the temperature sensors.
-
Complete check of the refrigerant charge (R-22), still stable and in line with expected values.
This intervention restored cooling performance without a complete replacement of the system, extending the life of the device by several years.
Responsible and economical repair
At AirGreen, we always advocate repair before replacement , whenever possible and economically viable. This saved the customer an immediate investment in a new unit, while still ensuring optimal operation for the summer season.
However, our technician took the time to explain the limitations of a system using R-22 , a refrigerant now discontinued. We advised the owner to plan, in the medium term, a transition to a more environmentally friendly and energy-efficient R-32 refrigerant system .
