Troubleshooting and Repair of a Bco Wall-Mounted Heat Pump in Sainte-Anne-de-Bellevue, South Shore

At AirGreen, we understand the importance of having a high-performance and reliable HVAC (heating, ventilation, and air conditioning) system, especially during hot or cold weather. That’s why we make every effort to offer superior repair and maintenance services. Today, we’re sharing the story of a service call for a Bco wall-mounted heat pump in Sainte-Anne-de-Bellevue, a city located on the South Shore of Montreal.

The Challenge Faced by the Client

The client reached out to AirGreen after noticing that their Bco wall-mounted heat pump was no longer working as it should. The system was no longer cooling the space as it had in the past, which quickly led to discomfort in the home. With summer fast approaching, the client expressed concern. We responded immediately to their request, knowing that quick repairs were essential to restore comfort and security to our client.

Initial Diagnosis

Upon arrival, our heat pump repair technicians performed a thorough diagnostic to identify the root cause of the issue. After completing several checks, it became apparent that the compressor of the Bco heat pump had failed, preventing the unit from operating properly. Additionally, the accumulation of dirt in the ducts and a low refrigerant level contributed to the system’s inefficiency.

Our experts immediately explained the causes of the malfunction to the client and proposed appropriate solutions. They recommended replacing the compressor and conducting a deep cleaning of the system to remove contaminants. We also suggested a refrigerant recharge to ensure optimal performance.

Repair Process

After receiving the client’s approval, our technicians began the repair work. Here are the steps we followed to get the Bco heat pump back to working condition:

  1. Compressor Replacement: A new compressor was installed, restoring the heat pump’s ability to produce cool or warm air efficiently.

  2. Thorough Cleaning: Our technicians cleaned the filters, coils, and air ducts to remove any dust, dirt, and other debris that could hinder the system’s operation.

  3. Refrigerant Recharge: After checking the refrigerant levels, we proceeded to recharge the refrigerant so the system could operate at full capacity.

  4. Performance Testing: Finally, a series of tests were conducted to ensure the heat pump was working properly before putting it back into service.

Final Outcome and Customer Satisfaction

Once the repairs were completed, the Bco wall-mounted heat pump was working like new, ensuring optimal thermal comfort for our client. We also made sure that all features were fully operational, guaranteeing that both performance and energy efficiency were restored.

The client was extremely satisfied with the quality of our work and the speed with which we resolved the issue. They were able to once again enjoy their HVAC system in full comfort, knowing it was handled by a professional and experienced team.

The tour

What we check on a job like this one

Each number is a point we check on site. Switch between summer and winter to watch air and heat move.

Generic diagram: wall-mounted heat pump, indoor and outdoor units

In summer, the outdoor unit rejects the house's heat outside.

Generic illustration of this type of installation, not a survey of this job site. Tap a number.

  1. Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.

  2. The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.

  3. Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.

  4. A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.

  5. The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.

  6. On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.

  7. The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.

Frequently asked questions

What people ask us about this kind of work

9 questions
What should I have ready before calling?
The model (on the unit's label), the error code if there is one, the symptoms and how long they have lasted.
Repair or replace?
It depends on the unit's age, the failure and the cost of parts. We present the options after the diagnosis.
Does a wall-mounted heat pump heat in winter?
Yes, it heats and cools. Its capacity drops in very cold weather; the operating range depends on the model and is listed on its spec sheet.
Wall-mounted or multi-zone: how do I choose?
One wall head and one condenser outside: the direct solution for a room or an open area. For two to five rooms, a multi-zone puts one head in each room on a single condenser.
Where does the outdoor unit go?
Where it stays above the snow, clear and accessible, away from walkways. We decide it with you during the estimate.
Are there grants?
Depending on the model and your situation, assistance programs may apply, including Hydro-Québec's LogisVert. AirGreen checks the model number before quoting an amount. See the grants.
Do I need a permit?
Rules vary from city to city: location, distances, noise. See permits and by-laws, and we check for your address.
Does AirGreen hold the required licences?
Yes. AirGreen holds RBQ licence 5645-9605-01, subclasses 15.8 Ventilation, 15.10 Refrigeration and 16 Electricity.
