  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.

Breathe Easy with a Fresh Start: How Our Expertise Revitalized a Moldy Heat Pump

When it comes to maintaining a comfortable and healthy home environment, the efficiency and cleanliness of your HVAC system are paramount. Recently, AirGreen had the opportunity to showcase our expertise in Outremont, Montreal, where we tackled a particularly challenging yet rewarding task: the cleaning and washing of a wall-mounted heat pump. This project not only restored the unit to its original efficiency but also eradicated a pervasive mold problem that had been affecting the air quality and health of the household.

The Challenge: A Mold-Infested Heat Pump

Upon arrival at the scenic neighborhood of Outremont, our skilled technicians were greeted with a wall-mounted heat pump that had seen better days. Over time, the unit had become a breeding ground for mold, largely due to humidity and lack of regular maintenance. The homeowner had noticed a musty smell wafting through the air, a clear sign that something was amiss with their heating and cooling system.

Our Approach: Meticulous Cleaning Inside and Out

Understanding the urgency of the situation, our team sprang into action with a comprehensive plan to tackle both the interior and exterior components of the heat pump. Here’s how we ensured a thorough cleanse:

  • Initial Inspection: We started with a detailed assessment to identify all mold-infested areas.
  • Protective Measures: To ensure no spores spread to other parts of the home during cleaning, we sealed off the work area.
  • Deep Cleaning: Using eco-friendly and powerful cleaning agents, we meticulously scrubbed every nook and cranny of the heat pump.
  • Sanitization: After cleaning, the entire system was sanitized to kill any remaining mold spores, preventing future growth.
  • System Check and Test: Post-cleaning, we conducted a full system check to ensure the heat pump operated at peak efficiency.

The Results: Beyond Expectations

The outcome of our intervention was nothing short of remarkable. Not only did we eliminate the mold and its accompanying odor, but the heat pump’s functionality improved, making it operate as if it were brand new. The homeowner was particularly impressed with the level of care and attention to detail our team displayed throughout the process.

Frequently asked questions

What people ask us about this kind of work

9 questions
How often should maintenance be done?
It depends on the unit and how it is used; the manufacturer gives the frequency. Filters get checked much more often than the full service.
Does maintenance improve performance?
A dirty filter, coil or core cuts airflow and makes the unit work harder. Cleaning them restores the airflow.
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.
