A service call in a bright West Island condo
At AirGreen , we recently repaired a Midea wall-mounted heat pump installed on a condo balcony in Beaconsfield , in Montreal's West Island. The customer contacted us after noticing that their heat pump was no longer starting, even though the indoor unit indicator light appeared to be on. This is a common situation that, in a context of extreme heat, requires rapid and precise intervention.
First observation: a well-maintained device, but a subtle electrical fault
The Midea outdoor unit was installed on anti-vibration mounts , very stable and protected by a metal guardrail. Despite a relatively clean and clear environment, our technicians immediately detected a power supply problem at the wall box. When checking the voltage, they noted an intermittent outage: a slightly burnt wire was causing a loss of contact, preventing the compressor from starting.
For this type of breakdown, the experience and rigor of our technicians make all the difference. At AirGreen, we always proceed in methodical steps:
-
Voltage test at the power supply box .
-
Complete visual inspection of wiring and connectors.
-
Checking continuity between the indoor unit and the compressor.
-
Controlled reboot after problem fixed.
Intervention: secure, repair, and protect
Once the source of the problem is identified, we have:
-
Replaced the damaged section of cable inside the wall power box.
-
Applied insulating heat shrink tubing to prevent moisture infiltration.
-
Checked the grounding and tightened all connections.
We also took advantage of the visit to inspect the R-410A refrigerant charge , as the pressure values were within Midea's recommended standards. The customer appreciated this preventive check, which helps avoid future costs related to a compressor leak or overheating.
A Midea heat pump, efficient and reliable
Midea wall-mounted units are renowned for their energy efficiency and durability, but like any HVAC unit, they depend on careful installation and regular maintenance . In this condo, the 12,000 BTU unit served an open common area (living room and kitchen), perfect for a Mini-Split configuration.
Our technicians reminded the customer of some essential advice:
-
Avoid placing plants or decorative objects too close to the condenser to ensure good air circulation.
-
Clean the internal filter every month during the summer season.
-
Have the electrical system inspected every two years, especially for condos exposed to direct sunlight like this one.
Final test and validation
After the repair, we performed a complete system test :
-
The Midea compressor has restarted normally.
-
The pressures stabilized at perfect values for an outside temperature of 28°C.
-
The temperature of the blown air inside dropped to 9°C in less than 4 minutes.
We also checked the compressor noise level , measured at only 52 dB , proof that the system was back in perfect working order.
