In the snowy residential neighborhood of Chomedey in Laval, our teams recently completed a installation of a SHARP ZU1 15,000 BTU wall-mounted heat pump, a solution perfectly suited to the Quebec climate and the growing demand for energy performance and four-season comfort. This project once again showcases our expertise in residential HVAC installation in urban settings.
A harsh climate that requires a reliable heat pump down to -27 °C
Winters in Laval are unforgiving. During this installation, the outdoor conditions were icy, with a layer of black ice covering the paved surface. Installing a reliable HVAC system in such conditions requires more than just a good product: it demands expertise, precision, and attention to detail. The SHARP ZU1 wall-mounted heat pump is specifically designed to withstand these extremes, with heating capacity maintained down to -27 °C without loss of performance.
Why the SHARP ZU1 15,000 BTU model?
We recommended this model for several key reasons:
-
Integrated Plasmacluster Technology: This unique air purification system releases positive and negative ions that neutralize viruses, bacteria, mold, and allergens suspended in the air.
-
R-32 Refrigerant: An eco-friendly choice, with a global warming potential reduced by more than 65% compared to R-410A.
-
Excellent energy efficiency: With a SEER of 24 and an HSPF of 11.8, this heat pump offers significant savings on electricity bills, especially during the cold months.
-
Quiet operation: Indoors, the noise level can drop to as low as 23 dB, providing remarkable acoustic comfort.
Key steps of the installation in Chomedey
Environmental analysis and planning
Before installation, our technicians conducted a thermal analysis of the residence to ensure that the 15,000 BTU capacity was suitable for the area to be covered. The location of the outdoor unit was also strategic: we chose a spot sheltered from prevailing winds while facilitating condensate drainage, a crucial element in this area highly exposed to freezing.
Secure installation of the outdoor unit
As shown in the photo, the outdoor unit was placed on solid, elevated support blocks to avoid any contact with ice buildup. We also integrated protections against ice backflow and moisture rise.
A DucanTech enclosure ensures a secure electrical connection, meeting current standards for outdoor HVAC systems.
Integration of the indoor unit and commissioning
The indoor unit was mounted at an ideal height to optimize the Coanda airflow, a SHARP-specific technology that allows even air distribution throughout the room without blowing directly on occupants.
After the complete installation, our technicians conducted performance tests, validated the system’s efficiency, and took the time to explain to the client how the smart remote control works and the available modes (heating, cooling, dehumidification, ventilation).
Respiratory comfort thanks to Plasmacluster purification
In addition to regulating temperature, this heat pump significantly improves indoor air quality. Thanks to Plasmacluster technology, occupants enjoy a healthier environment, free of persistent odors, airborne viruses, and with fewer allergens – an important benefit in a neighborhood like Chomedey where many families live with children or seniors.
An energy-efficient system eligible for subsidies
This SHARP ZU1 model qualifies for government subsidies and rebate programs such as Hydro-Québec’s LogisVert program, when criteria are met. We always assist our clients with these processes to maximize their return on investment.
Challenges overcome by our team
-
Icy ground: Need to secure the installation to prevent infiltration and slipping.
-
Negative temperatures during installation: Testing the system’s proper operation under real conditions right from installation.
-
Respect for residential aesthetics: The outdoor unit was installed to minimize its visual impact while ensuring optimal performance.
Maintenance tips to ensure the heat pump’s longevity
-
Regularly clean the HEPA filter to maintain air quality.
-
Check condensate drainage in winter to prevent ice buildup.
-
Schedule annual HVAC maintenance with AirGreen to ensure efficient operation year after year.
What the client in Chomedey takes away
At the end of the project, our client expressed great satisfaction with the speed of the installation, the administrative support for subsidies, and especially the instant thermal comfort in her home. Thanks to an installation by AirGreen, she is now ready to face all Laval winters with complete peace of mind.
