A High-Performance Central Solution for Quebec Winters
In the field of HVAC in Montreal, Laval, Longueuil, North Shore, and South Shore, some solutions stand out for their ability to combine power, energy efficiency, and installation flexibility. The FORESTAIR E-TECH+ 3-ton (36,000 BTU) electric furnace is one such system that we regularly install at AirGreen for residential and multi-dwelling projects where heating performance is non-negotiable.
This model integrates perfectly with a compatible central heat pump, offering a smart hybrid solution capable of maintaining constant comfort even when temperatures drop below -25°C, which is essential in our Quebec climate.
Technical Design Focused on Real Performance
A Robust System Adaptable to All Configurations
One of the most appreciated aspects of this model is its installation flexibility. Unlike several more limited systems, this furnace can be installed in:
- Vertical (upflow) configuration
- Horizontal left or right
- Downflow / counterflow configuration
This allows our AirGreen team to adapt to complex situations, particularly in:
- Narrow basements in Montreal
- Technical condos in Laval
- Multi-dwelling installations in Longueuil
According to the technical documentation, this unit is designed with commercial-grade materials, ensuring increased durability and better wear resistance.
ECM Motor: Efficiency and Precise Control
The presence of an ECM (Electronically Commutated Motor) is a key element. Unlike standard motors:
- It automatically adjusts speed according to demand
- It reduces electricity consumption
- It improves air distribution throughout the house
With its 5 fan speeds, the system allows for precise airflow adjustment, a major advantage for homes with varying needs between floors.
Energy Performance and Real-World Capacity
Power Adapted to Quebec Homes
With a nominal capacity of 36,000 BTU (3 tons), this furnace is perfectly suited for:
- Medium to large single-family homes
- Duplexes and triplexes
- Properties with standard or improved insulation
Technical data indicates:
- Heating capacity up to 34,200 BTU
- Heating operating range: -25°C to 24°C
- Modulated capacity up to 39,000 BTU at peak
This concretely means that the system can maintain stable performance even during the periods of intense cold that we regularly observe on the South Shore and North Shore.
Energy Efficiency and Savings
The performance indicators are particularly interesting:
- SEER2: 18.0
- HSPF2: 9.0
- COP: 3.60 at 8°C
This translates to:
- Reduced consumption in cooling mode
- High heating efficiency, even in winter
- Eligibility for energy subsidies
Humidity Management and Indoor Comfort
One aspect often overlooked by homeowners is humidity management. This unit stands out for:
- A dehumidification capacity of 7.0 pints/hour
- An A-coil evaporator optimized for heat transfer
Result:
- More comfortable air in summer
- Less condensation
- Improved indoor air quality
In several installations in Montreal, we have observed a noticeable reduction in basement humidity problems after installing this system.
Silence and Acoustic Comfort
Comfort is not limited to temperature. Noise level is also a determining factor.
- Indoor unit: approximately 62 dB
- Outdoor unit: approximately 56 dB
These levels are considered low for a central system of this capacity. This allows for:
- Installation without noise nuisance in homes
- Ideal integration into dense urban environments like Montreal
AirGreen Installation: Field Expertise and Concrete Realities
Real-World Installation Example on the South Shore
During a recent project in Boucherville, we replaced an old inefficient electrical system with this FORESTAIR E-TECH+ 3-ton.
Challenges encountered:
- Very limited mechanical space
- Existing undersized ducts
- Excessive noise from the old system
Solutions provided:
- Adaptation to horizontal configuration
- Airflow adjustment using the ECM motor
- Duct optimization without complete reconstruction
Result:
- Energy bill reduction of approximately 22%
- Uniform thermal comfort throughout the house
- Reduced perceived noise
Essential Technical Details to Know
Dimensions and Installation
- Indoor unit dimensions: 19.61 x 21.58 x 46.5 inches
- Maximum airflow: up to 1229 CFM
- External static pressure: 0.5 in.W.C
This data is crucial to ensure compatibility with existing ducts.
Refrigerant R-454B: A Modern Choice
This system uses R-454B, a greener gas than previous generations:
- Reduced environmental impact
- Better energy efficiency
- Compliance with new standards
Electricity and Safety
- Voltage: 220V
- MCA: 32A
- Recommended circuit breaker: 35A
Our teams always ensure that the electrical panel complies before any installation.
Common Mistakes to Avoid
Throughout our HVAC projects in Greater Montreal, some mistakes frequently recur:
Incorrect Sizing
Installing a unit that is too large or too small can lead to:
- Overconsumption
- Thermal discomfort
- Premature wear
Neglecting Ducts
Even the best furnace will not perform correctly with poorly designed ducts.
Unprofessional Installation
A poorly installed system can reduce efficiency by more than 30%. At AirGreen, every installation is carried out by experienced refrigeration technicians.
