Before/After in Pictures: Complete Modernization of an Old Electric Baseboard System with Central Heat Pump

An Energy Transformation in the South Shore: Toward Modern and Sustainable Comfort

In this article, we take you inside one of our most illustrative projects in HVAC modernization. **At AirGreen, we recently replaced an old electric baseboard heating system with a high-efficiency central heat pump, bringing a radical transformation in comfort, energy savings, and environmental performance. This installation, carried out in Montréal’s South Shore, showcases our technical expertise and commitment to sustainable and efficient HVAC solutions for Québec homes.

Why Replace Electric Baseboards with a Central Heat Pump?

While electric baseboards are still present in many residential buildings, they are energy-intensive systems that fall short of current comfort and efficiency standards. In contrast, a modern central heat pump offers:

• Even heating and cooling distribution throughout every room.

• Significant reduction in annual electricity consumption.

• Greater eligibility for government grants, notably through Hydro-Québec’s LogisVert program.

• Enhanced comfort, with more stable indoor temperatures year-round.

Technical Details of the Installation: From Planning to Commissioning

Equipment Installed: Bosch BOVA 36K R-410A Central Heat Pump

In this single-family home in Longueuil, we installed a Bosch BOVA 36,000 BTU central heat pump, paired with a Bosch BVA electric furnace, using R-410A refrigerant. This combination delivers balanced performance for the harsh climate of Greater Montréal:

• Heating and cooling capacity: 36,000 BTU (ideal for homes of ±1,800 sq. ft.).

• Inverter technology: variable compressor speed for stable and energy-efficient performance.

• Low noise: quiet compressor with insulated ductwork.

• Central duct system: optimal air distribution throughout the home.

Key Stages of the Installation Project

1. Thermal Load Analysis and Technical Visit
Our certified technicians first assessed the required capacity based on insulation, window quality, and air volume. A full heat load analysis allowed us to recommend the most suitable heat pump for the home’s layout.

2. Removal of the Old System
The old electric baseboards in all main rooms were dismantled. This freed up wall space and improved each room’s visual appeal.

3. Ductwork Installation
We designed a galvanized ductwork system and installed discreet diffuser grilles in the ceilings and floors, depending on the room. This ensures uniform air distribution, with no direct drafts.

4. Furnace and Outdoor Unit Setup
The system’s core was installed in the basement, while the outdoor unit was placed on a raised concrete base and protected from the elements.

5. Programming and Calibration
We integrated an Ecobee smart thermostat, giving the homeowner precise remote control via a mobile app. Our specialists calibrated the system to optimize performance based on the occupants’ preferences.

Before / After: A Remarkable Modernization

Before

• Heating via electric baseboards in every room.

• No centralized air conditioning.

• High annual electricity consumption.

• Uneven heat distribution, frequent cold spots.

After

• Bosch 36,000 BTU central heat pump with electric furnace.

• Central air conditioning in all rooms.

• Estimated energy savings of over 30%.

• Eligible for LogisVert grant ($1,704).

• Uniform comfort throughout the house.

Technical Challenges of This Project

Every HVAC modernization project comes with specific challenges. In this case, the main issues included:

• Tight space for duct routing on the main floor, which we overcame by using optimized drop ceilings.

• Undersized existing electrical panel: our master electrician upgraded the main panel to handle the new system’s load.

• Limited basement access: all components were brought in modularly to avoid structural modifications.
