LG MULTI F MAX R32 2-Head Heat Pump | 60,000 BTU Compressor

BROCHURE

A multi-zone HVAC solution designed for demanding buildings in Quebec

At AirGreen , we have been installing and maintaining high-capacity HVAC systems for many years in a wide variety of settings: single-family homes, duplexes in Montreal, multi-unit buildings in Laval, commercial properties on the South Shore, and mixed-use buildings on the North Shore. The LG MULTI F MAX R32 2-Head Heat Pump with a 60,000 BTU compressor is one of the systems we recommend when heating and cooling needs far exceed those of a standard residential heat pump.

This model is aimed at property owners and managers who are looking for real power , multi-zone flexibility , stable heating in cold weather , and a scalable HVAC architecture capable of adapting to complex projects without compromising reliability.

A multi-zone architecture designed for the realities of Quebec buildings

One central system, multiple zones, one single control logic

The LG MULTI F MAX R32 – KUMXB601A features a robust outdoor unit capable of powering up to 8 indoor units , even though the configuration shown here is a 2-head installation . This feature is far from insignificant: it allows for future expansions , subdivisions, or the addition of new air-conditioned zones without having to replace the outdoor unit.

In practice, we often install this type of system in:

• triplexes and quadruplexes in Montreal where each unit has distinct thermal needs;

• intergenerational homes in Laval or Longueuil ;

• commercial offices requiring precise control by zone;

• rental buildings where heating stability is critical in winter.

A thermal capacity that can actually be used in real-world conditions.

Unlike many systems advertised with theoretical power ratings, the LG MULTI F MAX maintains solid performance at low temperatures:

• 60,000 BTU air conditioning

• 42,000 BTU at -8°C

• 46,000 BTU at -15°C

• Guaranteed operation down to -16°C in heating mode

On the ground, this translates into continuity of service in the middle of winter , even during the cold waves typical of Montreal, the Montérégie region or the North Shore.

High and measurable energy performance

Performance indicators adapted to current standards

This system displays remarkable efficiency values ​​for its category:

• SEER2: 20.5+

• HSPF2: 11.0+

• EER2: 12.0+

• COP at -8 °C: 2.01

These figures are not abstract: they translate concretely into better controlled electricity consumption , particularly important for buildings with continuous occupancy or high thermal load.

In several projects carried out by AirGreen on the South Shore , we have observed a significant reduction in annual energy costs compared to older centralized electrical systems or previous generation heat pumps.

R-32 refrigerant: a technical and regulatory choice

The R-32 gas used by this model offers:

• better thermal performance than R-410A;

• a lower global warming potential ;

• increased compliance with current environmental guidelines in Quebec.

For owners concerned about the regulatory sustainability of their HVAC system, this is a determining factor.

Technical design: what we, as installers, consider

A variable-speed compressor designed to last

The system is equipped with a variable-speed scroll compressor , with:

• gradual start,

• protection against rapid restarts,

• fine electronic management of thermal load.

This significantly reduces mechanical wear, a crucial point in heavily stressed multi-zone installations.

Flexible but demanding refrigeration network

The LG MULTI F MAX allows for complex configurations:

• Total piping length up to 475 ft

• Height difference up to 98 ft

• Mandatory use of distribution modules

At AirGreen , we always emphasize precise refrigeration network design from the initial bidding phase. Poor planning at this stage is one of the most frequent causes of performance problems in multi-zone systems. Our teams take the time to calculate equivalent lengths, additional refrigerant charges, and elevation constraints before any installation.

Acoustic comfort: an often underestimated criterion

Quiet interior, even when fully loaded

Depending on the indoor units chosen, the indoor noise level can drop to 29 dB(A) . In the dense urban housing of Montreal or the condos of Longueuil, this feature makes a real difference in everyday life.

Controlled outdoor unit

With 58 dB(A) in operation, the outdoor unit remains compatible with the majority of municipal regulations, even in tight residential environments.

Compatibility, connectivity and smart control

Wi-Fi included and advanced management

The system is compatible with LG smart control solutions:

• remote monitoring

• advanced diagnostics,

• Possible integration with centralized management systems.

For owners of multi-unit dwellings or property managers, this allows for proactive maintenance and rapid detection of anomalies.

LogisVert subsidy: a concrete financial lever

At the time of writing, this heat pump is eligible for a $2,100 LogisVert provincial grant (updated November 26, 2025). We systematically assist our clients in preparing their applications , as an administrative error can delay or cancel otherwise legitimate financial assistance.

Why entrust the installation to AirGreen

Practical expertise, not just theoretical.

We have installed LG MULTI F systems in complex environments: narrow stairwells, commercial rooftops, cramped mechanical rooms, and existing buildings without the possibility of ductwork. Each project reinforces our understanding of the real-world constraints of Quebec buildings.

Clear commitments

• Transparent pricing before work begins

• Certified refrigeration technicians

• $5,000,000 liability insurance

• Structured and local after-sales service

Who is this heat pump really intended for?

This system is ideal if you are looking for:

• a high-end, multi-zone, centralized HVAC solution

• real power for large areas ,

• long-term scalability ,

• stable heating comfort even in very cold weather .

• an installation that complies with current and future standards .

Conclusion

The LG MULTI F MAX R32 2-Head Heat Pump | 60,000 BTU is not a generic product. It is a structured HVAC solution , designed for ambitious projects where performance, reliability, and flexibility are non-negotiable.
