A Simple HVAC Optimization that Transformed Comfort in a North Shore Cottage

When it comes to heating, many homeowners seek efficient solutions to lower their energy bills while enhancing the comfort of their living spaces. At AirGreen, we recently helped a client achieve an impressive milestone on the North Shore: reducing his heating bill by nearly 40% through an ingenious yet straightforward HVAC solution. Here’s how our team significantly improved thermal comfort in a cottage near Saint-Jérôme while generating substantial savings.

The Initial Problem: High Energy Bills Despite Good Insulation

The cottage owner, located in a natural setting near Saint-Jérôme, faced a common issue experienced throughout the North Shore region: despite recently updated and effective insulation, his heating costs remained high, especially during Québec’s harsh winter months.

After attempting various methods to reduce expenses, such as adjusting thermostats and enhancing insulation further, he was considering costly renovations or purchasing a completely new heating system. That’s when he contacted AirGreen for expert advice.

Our Precise HVAC Diagnosis to Identify Energy Loss Sources

Before proposing any solution, our team conducted an extensive assessment of the existing HVAC installations. The cottage had traditional electric heating combined with an aging ventilation system. A thermal analysis quickly identified significant energy losses due to inadequate heat distribution throughout the cottage.

Despite excellent insulation, heat accumulated near the ceiling, causing discomfort in living areas and forcing the heating system to run continuously to compensate for these temperature fluctuations.

The Simple HVAC Trick: Strategic Installation of a High-Efficiency Wall-Mounted Heat Pump

The solution recommended by our technicians was both simple and remarkably effective: installing a high-efficiency Fujitsu Halcyon XLTH wall-mounted heat pump with an 18,000 BTU capacity. This particular heat pump, especially suitable for extremely cold North Shore temperatures, offers exceptional energy efficiency due to its high coefficient of performance (COP), effectively utilizing energy to heat the cottage.

The targeted installation was strategically placed in the cottage’s central room, optimizing the uniform distribution of warm air throughout all inhabited areas, thereby preventing typical energy losses caused by convection.

Challenges Encountered During the Heat Pump Installation in Saint-Jérôme

Every project, even seemingly simple ones, can encounter technical hurdles. The primary challenge in this installation was ensuring optimal circulation of warm air throughout the cottage, which featured high ceilings.

To address this, our team designed a custom solution: installing the heat pump at an optimal height and integrating a quiet, low-energy fan to effectively push warm air downward. This immediately enhanced comfort, particularly on the ground floor, where occupants spend most of their time.

Concrete Results: Exceptional 40% Reduction in Heating Costs

After installing the Fujitsu Halcyon XLTH wall-mounted heat pump, the cottage owner immediately noticed significant improvements in thermal comfort. However, the true surprise arrived with the next winter electricity bill: a nearly 40% reduction compared to the same period the previous year!

These substantial savings were primarily due to drastically reduced reliance on the highly energy-consuming electric baseboard heaters, now effectively supplemented by the heat pump. Additionally, overall cottage comfort improved significantly, with pleasant and consistent warmth throughout each room.

Why the Fujitsu Halcyon XLTH Heat Pump is Ideal for North Shore Cottages

  • Superior cold-climate performance: Specifically designed for Québec’s harsh winters.

  • Low energy consumption: High COP ensures significant savings.

  • Uniform heat distribution: Prevents uncomfortable temperature fluctuations.

  • Eligibility for government grants: The client benefited from a LogisVert subsidy of $1,704, significantly offsetting the initial investment.
