How does AirGreen actually test the winter performance of wall-mounted heat pumps at -30°C?

The truth behind our rigorous testing: How AirGreen guarantees your wall-mounted heat pump's winter performance in extreme temperatures

At AirGreen, we understand that the winter reliability of your wall-mounted heat pump is crucial for everyday comfort in Montreal, Laval, Longueuil, the North Shore, and the South Shore. But how can we be certain our HVAC equipment will perform flawlessly even at -30°C? Here's exactly how our team carries out real-life tests, pushing each wall-mounted heat pump to its limits to give you an absolute performance guarantee.

Our testing process: real-world conditions for wall-mounted heat pumps

Before installing a wall-mounted heat pump like the Fujitsu KZAH, Gree Sapphire, or Bosch BIVA IDS Premium models, we conduct a rigorous series of tests to evaluate their true performance under Quebec’s typical extreme winter conditions.

Here's how we structure our tests:

• Real environmental conditions: We perform outdoor tests during actual Quebec winters, not only in laboratory settings. This means exposing units to extreme temperatures that can reach as low as -30°C.

• Extended operational cycles: Each wall-mounted heat pump undergoes prolonged heating cycles to simulate intensive and continuous household usage.

• Precise performance measurements: Our technicians use precision instruments to continuously measure produced air temperature, electricity consumption, energy performance (COP), and operational stability.

Real-life case: extreme testing of a Gree Sapphire wall-mounted heat pump in Laval

During a recent project in Laval, our AirGreen team installed an 18,000 BTU Gree Sapphire wall-mounted heat pump. Before finalizing the installation for our client, we subjected this unit to extensive testing in January, where temperatures reached as low as -30°C.

• Challenge encountered: At these extreme temperatures, it’s common for some heat pumps to lose efficiency or temporarily shut down.

• AirGreen’s solution: Our technicians implemented advanced configuration by optimizing internal heat pump settings to maintain consistent heat output while reducing the frequency of necessary defrost cycles.

• Result: The Gree Sapphire heat pump maintained stable thermal comfort without interruption, achieving a satisfactory COP greater than 2, even at -30°C, fully validating its performance for Quebec's harsh winters.

Essential technical criteria evaluated by our experts

At AirGreen, every wall-mounted heat pump is evaluated according to strict and specific technical criteria to ensure exceptional reliability:

• Coefficient of Performance (COP): We precisely verify the real COP at very low temperatures. This key factor measures energy efficiency under extreme winter conditions.

• Effective defrost capability: We thoroughly test the automatic defrost operation, essential for preventing ice buildup that can significantly reduce performance.

• Recovery time after defrost: We carefully analyze how quickly the heat pump returns to full capacity after each defrost cycle.

• Interior temperature stability: We systematically control the consistency of indoor temperatures to ensure continuous thermal comfort for our clients.

Practical example: optimizing a Bosch BIVA IDS Premium heat pump in Montreal

During an installation in Montreal, we tested and optimized a Bosch BIVA IDS Premium 12,000 BTU wall-mounted heat pump. Facing temperatures as low as -28°C over an extended period, the AirGreen team identified frequent defrost cycles temporarily reduced heating capacity.

• Corrective actions: We precisely adjusted internal settings to increase intervals between defrost cycles without compromising the unit’s safety.

• Result achieved: After optimization, the Bosch BIVA IDS Premium demonstrated improved energy efficiency and greater indoor heating stability, even under these extreme winter conditions.

Why these thorough tests make all the difference

These comprehensive tests conducted by AirGreen provide several tangible benefits to homeowners and property managers in Montreal and surrounding areas:

• Peace of mind: A genuine assurance that your wall-mounted heat pump will operate efficiently during the harshest winter conditions.

• Significant energy savings: A heat pump optimized for Quebec’s climate consumes less energy during intense winter periods, lowering your electricity bills.

• Increased durability: Our rigorous testing extends equipment lifespan by reducing unnecessary start-and-stop cycles.

Real testimonial: comfort assured by a Fujitsu KZAH heat pump in Longueuil

In Longueuil, a customer who chose a Fujitsu KZAH heat pump shared her experience during the freezing days of last February:

• “Thanks to the meticulous testing and adjustments done by AirGreen, my Fujitsu wall-mounted heat pump operated continuously, even when outdoor temperatures were extremely low. I was able to maintain stable and pleasant warmth while significantly reducing my energy consumption.”
