Repair of a Synergie wall-mounted heat pump in Sainte-Thérèse

When a simple unusual noise reveals a deeper problem

At AirGreen , our service calls are never limited to a quick diagnosis. Every intervention is an opportunity to give our customers the comfort and peace of mind they deserve. This is exactly what happened during our recent repair of a Synergie wall-mounted heat pump in Sainte-Thérèse , on the North Shore of Montreal.

A call for an abnormal noise

The customer contacted us after noticing a constant metallic noise coming from their outdoor unit. Looking at the photo above, you can clearly see the Synergie wall-mounted condenser unit securely mounted to a red brick wall , typical of single-family homes in the area. The installation had been done a few years earlier by another contractor, and the owner was concerned that the fan might fail .

Accurate diagnosis and complete inspection

Our technicians carried out a three-step inspection :

  1. Visual assessment of the exterior mounting: the metal structure supporting the unit was solid, but slightly misaligned, causing abnormal vibrations against the wall.

  2. Fan rotation test : The motor was turning, but a slight rubbing sound was heard with each revolution.

  3. Electrical analysis : The compressor supply current and connections were correct.

The final diagnosis revealed two problems:

  • Sagging silent blocks causing excessive vibrations.

  • Worn fan bearing , causing the metallic noise heard.

On-site repair

Our experts removed the condenser front to access the fan impeller and motor.

  • Step 1: Removal of the original silent blocks and installation of new high-quality anti-vibration dampers .

  • Step 2: Replace the fan motor with a Synergie compatible part, verified and guaranteed.

  • Step 3: Complete cleaning of the condenser coil and checking the R-410A refrigerant level to ensure optimal pressure.

Once the repairs were made, we tested the system for over 30 minutes. The noise was gone and the unit was operating at full capacity , once again providing efficient heating and cooling.

The result: comfort and performance restored

Thanks to this intervention, the client found:

  • Quiet operation even at full power.

  • Restored energy efficiency , reducing electricity consumption.

  • A secure installation , free from vibrations that could damage the masonry.

At AirGreen, we always remind our customers of the importance of annual preventative maintenance . Many breakdowns, like this one, can be avoided with a simple spring check.
