A high-performance central HVAC solution perfectly suited to Greater Montreal's climate
At AirGreen, we install central HVAC systems that must meet a very specific reality: harsh winters, significant temperature variations, and high expectations for comfort and energy efficiency. The 3-ton (36,000 BTU) LG LGRED R32 electric furnace stands out as an extremely relevant solution for homes and small commercial buildings in Montreal, Laval, Longueuil, on the North Shore, and the South Shore.
This system, combined with the compatible LG central heat pump (KUSXA361A), allows for intelligent heating and cooling management, with remarkable stability even at low temperatures. We have installed several similar units in single-family homes and duplexes in Montérégie and on the North Shore, with tangible results in terms of comfort and energy savings.
Why choose a 3-ton LG LGRED R32 electric furnace?
Exceptional thermal performance down to -25°C
This system is distinguished by its ability to maintain reliable performance even in very cold weather. Specifically:
- Nominal power: 36,000 BTU
- Capacity at -8 °C: 25,400 BTU
- Capacity at -15 °C: 33,000 BTU
- Stable operation down to -25 °C
In several installations carried out by AirGreen in Laval and Longueuil, this type of equipment has significantly reduced the use of traditional electric auxiliary heating, while maintaining a uniform indoor temperature.
Superior energy efficiency
Efficiency is at the heart of this system:
- SEER2: 18.20
- HSPF2: 9.60
- COP at 47°F: 3.79
- ENERGY STAR® and ENERGY STAR® Cold Climate Certification
This means that the system offers excellent performance in both cooling and heating, which directly translates into reduced energy costs.
Detailed technical data for an informed decision
Airflow and indoor comfort
Comfort depends not only on power, but also on the quality of air distribution:
-
Airflow (CFM):
- High speed: 1,050 CFM
- Medium: 980 CFM
- Low: 900 CFM
- Sirocco fan with brushless motor for quiet and constant operation
- Adjustable external static pressure (ESP): 0.1 to 1.0 in.wg
During a project carried out in Boucherville, this airflow modulation capability allowed the system to be perfectly adapted to an existing duct network without major modifications.
Controlled sound level
- Indoor: 35 to 40 dB(A)
- Outdoor: approximately 54 dB(A)
This sound level is particularly appreciated in dense residential areas like Montreal, where noise from outdoor equipment can become an issue.
HVAC Installation: What we do differently at AirGreen
Comprehensive analysis before installation
Every project begins with a detailed analysis:
- Actual (not approximate) thermal load calculation
- Evaluation of the existing duct network
- Verification of electrical capacity (MCA: 32A / MOP: 35A)
We recently corrected an improperly sized installation in Laval where a 2-ton unit had been installed in a house requiring 3 tons. Replacing it with a 3-ton LGRED immediately stabilized the indoor temperature.
Clean, compliant and optimized installation
Our teams ensure:
- Duct installation with optimal sealing (professional aluminum tape)
- Installation of 3/8 - 5/8 piping
- Complete vacuum test before commissioning
- Airflow calibration to maximize efficiency
Every installation is carried out by certified refrigeration technicians, with particular attention to details often overlooked by other contractors.
R-32 Technology: A Concrete Advantage for Your HVAC System
The R-32 refrigerant used in this system offers several advantages:
- Better energy efficiency than R-410A
- Reduced environmental impact
- Better heat transfer capacity
In our recent projects on the South Shore, we observed a significant improvement in the overall performance of R-32 systems, particularly in heating.
AirGreen Case Study: Installation in Longueuil
In a renovated bungalow in Longueuil, the client faced:
- Uneven air distribution
- High electricity bills
- An aging, inefficient system
We installed:
- A 3-ton LG LGRED R32 furnace
- A compatible central heat pump
- Complete adjustment of the duct network
Result:
- Approximately 28% reduction in energy bills
- Homogeneous comfort in all rooms
- Significantly improved sound level
Frequent mistakes to avoid with this type of system
Improper Sizing
A system that is too small or too large leads to:
- Short cycling
- Premature wear
- Thermal discomfort
Neglecting the ductwork
Even the best system won't compensate for:
- Poorly insulated ducts
- Poor air distribution
- Inadequate static pressure
Uncertified installation
Inadequate installation can:
- Void the warranty
- Drastically reduce performance
- Create condensation problems
At AirGreen, we have often been called upon to correct poorly executed installations, which leads to avoidable additional costs.
Available subsidies and return on investment
This unit is eligible for the following program:
- LogisVert Grant: up to $3048
Thanks to this assistance, combined with energy savings, the return on investment becomes very attractive for homeowners in Montreal, Laval, and Longueuil.
Why choose AirGreen for your HVAC installation?
- Real expertise in central HVAC installation
- Field experience in Greater Montreal
- Total price transparency
- Certified and experienced technicians
- 5M$ civil liability insurance
We don't just install a system: we optimize every project to guarantee performance, durability, and satisfaction.
