This Laval Homeowner Reduced Their Electricity Bill by 40% Thanks to This Air Conditioning Trick

A perfectly tailored wall-mounted air conditioner installation for a family bungalow

In a quiet residential neighborhood of Laval, a homeowner recently contacted AirGreen for an air conditioning solution that was efficient, energy-saving, and above all, long-lasting. This client was looking to significantly reduce their electricity costs while maintaining consistent thermal comfort during the increasingly long and intense summer seasons in the region.

At AirGreen, we thoroughly analyzed their needs, energy use habits, the orientation of their bungalow, and the overall energy efficiency of the home. Thanks to this personalized approach, we recommended installing a Gree Lomo 12,000 BTU wall-mounted heat pump, a high-performance, energy-efficient, compact system that is fully eligible for Hydro-Québec’s LogisVert grants.

Why the Gree Lomo 12,000 BTU Was the Perfect Choice for This Laval Project

The Gree Lomo model is known for its reliability, great value, and its ability to deliver consistent comfort while consuming very little energy. This system is perfectly suited for single-family homes of small to medium size, just like our client's home in Laval.

Here are the main features of the installed model:

• Brand: Gree

• Model: Lomo

• Type: Wall-mounted heat pump (mini split)

• Capacity: 12,000 BTU

• Refrigerant: R-410A

• Energy efficiency: SEER 20 / HSPF 10.5

• Eligible for grants: Yes, LogisVert program – Hydro-Québec

• Quiet mode: Yes

• Heating function down to -20 °C: Yes

Thanks to its variable-speed compressor (Inverter), this heat pump optimizes energy consumption based on the actual needs at any given moment. That means it never runs at full capacity unnecessarily, resulting in up to 40% energy savings, as experienced by this Laval client after just a few months.

Details of the HVAC Installation Performed in Laval

The installation was carefully planned, taking the specifics of the building into account. The load-bearing wall where the client wanted the indoor unit installed was slightly offset from the main electrical outlets. Our team proposed a clean, technical solution by neatly redirecting the wiring and piping to the outside using discreet conduit covers.

Key Steps of the Project:

1. On-site initial evaluation, including precise measurements, thermal load analysis, and discussions with the client about priorities (quiet operation, efficiency, operating costs).

2. Drilling and secure installation of the indoor wall unit, with precise angling of the drainage tray to prevent water buildup.

3. Mounting of the outdoor unit on a concrete anti-vibration pad, with galvanized supports to withstand Laval’s harsh winters.

4. Commissioning and complete system testing: we verified there were no refrigerant leaks, measured system pressure, tested heating/cooling modes, and explained the system’s operation to the client.

Result: Optimal Comfort and Immediate Reduction in Electricity Usage

Just three months after the installation, our client called us back, pleasantly surprised by the results: their electricity bill had dropped by 40% compared to the same period the previous year. They told us that the heat pump now provides stable, comfortable temperatures in all the main rooms of their bungalow, without needing extra fans or energy-hungry portable units.

Thanks to the integrated mobile app, they can also remotely program their air conditioning cycles, allowing for even greater savings when they’re away from home.
