LG Multi-position Blower Cabinet | 2.5 Tons - 30000 BTU

A Powerful and Flexible Central HVAC Solution for Quebec's Climate

At AirGreen, we regularly install central HVAC systems in homes and multi-dwelling units in Montreal, Laval, Longueuil, on the North Shore and the South Shore. The LG 2.5-ton (30,000 BTU) multi-position blower cabinet stands out as a particularly reliable option for projects requiring efficient air distribution, compatibility with modern R-32 heat pumps, and flexible installation in confined technical spaces.

This model, identified as KNSLB301A, works in tandem with the outdoor unit KUSXB301A, forming a complete central system certified ENERGY STAR (including for cold climates), perfectly suited to Quebec's realities.

Why choose this LG blower cabinet for your HVAC installation

Installation versatility: a real advantage on site

The term multi-position is not just a marketing argument. On our job sites in Boucherville, Terrebonne, and Laval, we frequently encounter space constraints: low ceilings, narrow mechanical rooms, or renovation installations. This LG cabinet can be installed in vertical or horizontal positions, which allows us to optimize integration without compromising performance.

Stable thermal performance even in difficult conditions

Unlike several standard systems, this model maintains effective heating capacity down to -16°C, with a measured actual power of:

• 21,400 BTU at -8°C
• 30,000 BTU at -15°C

In Greater Montreal, where winter temperatures are unpredictable, this stability helps avoid electrical overloads or the premature addition of auxiliary heating.

Essential technical details to know

Capacity and energy efficiency

• Cooling capacity: 30,000 BTU
• Heating capacity: up to 36,600 BTU (max)
• SEER2: 17.0
• HSPF2: 9.60
• EER2: 11.70
• COP at -8°C: 1.85+ (depending on real conditions)

These performances allow for eligibility for the LogisVert subsidy, currently estimated at $2,568, which significantly reduces the overall project cost.

Airflow and indoor comfort

The system offers an airflow of up to:

• 875 CFM (high)
• 750 CFM (medium)
• 630 CFM (low)

In practice, this means uniform air distribution throughout the house, preventing cold or overheated zones—a problem we often correct when replacing old systems.

Sound level

• Indoor unit: 35 to 40 dB(A)
• Outdoor unit: approximately 54 dB(A)

During a recent installation in Longueuil, a client specifically mentioned the noticeable improvement in sound comfort compared to their old central system.

Modern technology at the heart of the system

R-32 refrigerant: efficiency and future-proof

This system uses R-32, a more efficient gas with reduced environmental impact compared to R-410A. At AirGreen, we strongly recommend R-32 systems for:

• Better energy efficiency
• Transition compliant with new environmental standards
• Increased heating performance

Variable speed motor (Inverter)

The variable speed compressor precisely adjusts power according to actual demand. The result:

• Fewer on/off cycles
• Energy savings
• More stable indoor temperature

In a project in Montreal North, this type of modulation reduced temperature variations by over 40% according to the client's readings.

HVAC installation: what we've learned in the field

Sizing: a critical step

A 2.5-ton (30,000 BTU) cabinet is not suitable for all properties. A common mistake is to oversize the system, which leads to:

• Short cycling
• Premature wear
• Poor dehumidification

At AirGreen, we always perform a complete thermal analysis before any installation.

Piping and configuration

• Required piping: 3/8" - 5/8"
• Maximum length: 164 feet
• Maximum elevation: 98.4 feet

These specifications allow us to adapt the installation to complex buildings, particularly in multi-dwelling units on the South Shore.

HVAC Maintenance: maximizing lifespan

A system like this can last 15 to 20 years, provided rigorous maintenance is followed:

• Annual coil cleaning
• Airflow verification
• Electrical inspection
• Refrigerant charge check

At AirGreen, we offer HVAC maintenance packages in Montreal and Laval, helping to avoid costly repairs.

Real case: installation in a duplex in Laval

During a recent project in Laval, we replaced an old inefficient electric system with this LG cabinet coupled with its heat pump.

Challenges encountered:

• Very limited mechanical space
• Unbalanced air distribution between floors

Solutions provided:

• Horizontal installation of the cabinet
• Adjustment of existing ducts
• Precise airflow calibration

Result:

• Reduction in energy bill of approximately 28%
• Uniform thermal comfort between floors
• Significantly reduced noise level

Concrete benefits for homeowners in Quebec

• Compatible with LogisVert subsidies
• Works efficiently in cold climates
• Flexible installation (multi-position)
• Compatible with smart systems (optional WiFi)
• Homogeneous air distribution

Why choose AirGreen for your installation

At AirGreen, we don't just install equipment. We ensure:

• A complete building analysis
• Installation compliant with RBQ standards
• Full price transparency
• Experienced technicians in residential and commercial HVAC
• Prompt and structured after-sales service
