A high-performance central solution designed for Quebec's climate

At AirGreen, we install hundreds of HVAC systems in Greater Montreal each year, and some equipment quickly stands out for its technical consistency and reliability in the field. The ELIOS R454B 2.5-ton electric furnace (air handler) is one of those systems we confidently recommend, especially when combined with a compatible central heat pump.

This specific model — EAHMA30R4AS1 — was designed to meet the real demands of residential and multi-dwelling properties in Montreal, Laval, Longueuil, the North Shore, and the South Shore, where winters frequently reach extreme temperatures. It is a central component that manages air distribution, optimizes indoor comfort, and ensures stable performance all year round.

Why choose the ELIOS R454B 2.5-ton Air Handler

A capacity perfectly suited for Quebec homes

With a capacity of 30,000 BTU, this system is perfectly suited for single-family homes, condos, or small residential buildings. It allows for homogeneous distribution of hot and cold air via an existing or new duct network.

Here's what distinguishes this model in the field:

• Power at -8°C: 37,000 BTU
• Power at -15°C: 46,000 BTU
• Compatible with central heat pump ESHMA30R2AN1
• Operation down to -30°C

This point is essential: unlike many systems that quickly lose efficiency, this combination maintains stable performance even in severe winter conditions.

Inverter Technology: Stability and Real Savings

The integration of Inverter technology allows for intelligent power modulation. In concrete terms:

• The system automatically adjusts its speed
• Reduces on/off cycles
• Decreases energy consumption
• Improves component lifespan

According to technical documentation, this technology provides consistent performance and better thermal control.

At AirGreen, we observe a noticeable reduction in temperature variations in rooms, which improves the overall comfort of occupants.

Certified Energy Efficiency

This model is certified:

• ENERGY STAR®
• ENERGY STAR® Cold Climate
• AHRI: 216046598

Performance indicators:

• SEER2: 16.8
• HSPF2: 8.3
• EER2: 11.7
• COP at -8°C: 3.65

These values confirm solid energy efficiency, which is particularly important for reducing electricity costs in regions like Montreal and Montérégie.

HVAC Installation: AirGreen's Feedback

Real Case – Installation in Boucherville (South Shore)

We recently installed this system in a 2-story house in Boucherville.

Challenges encountered:

• Limited mechanical space
• Inefficient old electrical system
• Uneven air distribution upstairs

Solutions provided:

• Compact installation thanks to optimized dimensions (21.02 x 21.02 x 49.02 in)
• Adjustment of the duct network
• Airflow calibration (CFM)

Result:

• Stable temperature throughout the house
• Reduced perceived noise
• Immediate improvement in comfort

Common mistakes to avoid

In our interventions in Laval and Longueuil, we often see the same problems:

1. Improper sizing
   → leads to overconsumption and premature wear
2. Installation without air balancing
   → creates cold or overheated zones
3. Lack of electrical validation
   → this model requires 220V / 30A (MCA & MOP)

At AirGreen, we systematically validate these parameters before any installation.

Indoor Comfort and Noise Level

Silence and quality of life

The indoor noise level varies between:

• 27.5 dB (low speed)
• 47 dB (max)

This means the unit operates discreetly, even in open spaces or finished basements.

Efficient Dehumidification

With a capacity of 5.7 pints/hour, this system actively contributes to:

• Reducing indoor humidity
• Improving air quality
• Preventing mold

This is particularly useful during humid summers in Montreal and on the North Shore.

R-454B Refrigerant: An Important Technological Transition

The system uses R-454B, a new generation refrigerant:

• Reduced environmental impact
• Optimized thermal performance
• Compliant with new standards

A key advantage: an integrated leak detection sensor automatically cuts off the compressor in case of a problem, ensuring continuous safety.

Flexible Installation and Compact Design

Adapted to confined spaces

The system's design allows for:

• Installation in compact mechanical rooms
• Less bulk than many competing models
• Better integration into renovations

According to the brochure, the condenser can be up to 40% more compact than traditional models.

Compatibility and options

• Piping: 3/8 - 3/4
• Maximum duct length: up to 164 feet
• Optional WiFi compatible thermostat
• Auxiliary heating available (3 to 25 kW)

Warranty and Reliability

• 10-year compressor
• 10-year parts
• Labor: 0 year (option available)

At AirGreen, we offer warranty extensions tailored to each client to ensure complete peace of mind.
