A high-end ducted solution designed for Quebec buildings

At AirGreen, we have been installing and maintaining HVAC systems for many years in a wide range of contexts: old and new single-family homes in Montreal , condos with low ceilings in Laval , renovated plexes in Longueuil , family residences on the North Shore , and multi-unit residential and commercial buildings on the South Shore . The FUJITSU CENTAURI R32 | 18,000 BTU ducted heat pump is one of the systems we recommend when clients are looking for a precise balance between visual discretion , energy efficiency , consistent thermal comfort , and long-term reliability , even in harsh winter conditions.

This type of heat pump isn't just for high-end projects. In the Quebec market, it's often the best solution for buildings where wall-mounted units would create temperature imbalances, noise, or significant aesthetic constraints. Thanks to its integration into a ductwork system, the ducted heat pump can heat and cool all spaces without being visually prominent in living areas.

Ducted technology with medium static pressure: a real advantage in the field

Static pressure makes all the difference in complex installations

The average static pressure , which can reach 0.8 inWG , is a key factor in the actual performance of a ducted system. In practice, this means that the ARUH18KUAS indoor unit is capable of maintaining a stable airflow even when the ductwork includes:

• significant lengths,

• several bends,

• zoning registers,

• section transitions.

At AirGreen, we frequently encounter this type of configuration, particularly in multi-story houses in Rosemont , duplexes in Villeray , and multigenerational buildings in Laval . In these contexts, low static pressure systems quickly show their limitations: poorly served rooms, air noise, and temperature fluctuations. Thanks to its automatic static pressure detection, the FUJITSU CENTAURI continuously adjusts its operation to ensure even distribution, eliminating the need for imprecise manual adjustments.

High airflow and even distribution

With an airflow of up to 1,618 CFM , this heat pump is perfectly suited for medium to large residential spaces. In several installations completed by AirGreen on the South Shore , this airflow efficiently supplied open-concept living areas combining a living room, kitchen, and dining room, while maintaining stable temperatures in bedrooms located away from the main plenum.

This ability to push air consistently also reduces thermal stratification, a common problem in homes with cathedral or mezzanine ceilings.

A truly noticeable acoustic comfort

Acoustic comfort is often underestimated when choosing an HVAC system. Yet, in everyday life, it quickly becomes a key factor in satisfaction. With an indoor noise level as low as 24 dB(A) in silent mode, the FUJITSU CENTAURI 18,000 BTU is virtually unnoticeable. Several customers report that, after a few weeks of use, they no longer hear the system operating, even during periods of intensive heating.

Energy performance and heating behavior in very cold weather

Measured yields, not just theoretical ones

In terms of energy efficiency, this heat pump boasts particularly solid values:

• SEER2: 18.6 for seasonal air conditioning

• HSPF2: 10.3 for seasonal heating

• COP of approximately 12 at -8°C , which is remarkable for a ducted system

In real-world use, this translates into stable and predictable electricity consumption. In Boucherville , at a client's home who replaced an aging central electrical system, we observed a significant decrease in peak winter consumption from the very first winter, while also improving the overall comfort of the house.

Maintaining capacity at low temperatures

The 18,000 BTU nominal capacity isn't just a marketing figure. At -8°C , the system still delivers approximately 14,400 BTU , and up to 17,100 BTU at -15°C . This progressive capacity is made possible by Inverter technology, which modulates the compressor speed instead of operating in on/off cycles.

In practical terms, this means:

• fewer temperature variations,

• less noise,

• less mechanical wear,

• improved system longevity.

In Quebec's climate, where winters are long and variable, this stable behavior is essential to ensure constant comfort without overconsumption.

R-32 refrigerant: a responsible and future-oriented choice

The FUJITSU CENTAURI uses R-32 refrigerant , known for its significantly lower global warming potential compared to previous generations. This technical choice allows for:

• a significant reduction in environmental impact,

• improved thermodynamic efficiency

• a lower refrigerant charge for equivalent or superior performance.

For homeowners planning their investment over 15 to 20 years, this point is far from insignificant. Regulations are evolving, and R-32 systems are clearly better positioned to remain compliant and relevant in the long term. For our teams, this also simplifies HVAC maintenance and service operations, with cleaner and more controlled interventions.

HVAC Installation: The AirGreen Approach, Step by Step

An installation that determines actual performance

Even the best equipment can disappoint if it's poorly installed. At AirGreen, every ducted heat pump HVAC installation follows a structured process:

• thermal analysis of the building

• validation of the area served by 18,000 BTU,

• inspection and optimization of the existing or planned conduit network,

• precise choice of pipe diameters ( 1/4 – 1/2 in ),

• static pressure adjustment,

• comprehensive heating and air conditioning tests.

We have found that many problems wrongly attributed to equipment actually stem from inadequate design or balancing of the distribution network. That's why we pay close attention to these details.

Physical integration and spatial constraints

The indoor unit, measuring approximately 39.38 x 27.56 x 11.81 inches , easily integrates into a suspended ceiling, mechanical room, or false ceiling. The compact and robust outdoor unit operates at a sound level of approximately 55 dB(A) , making it suitable for dense residential areas in Montreal or Longueuil without disturbing the neighbors.

Controls, automation and flexibility of use

The FUJITSU CENTAURI ducted heat pump offers great configuration flexibility:

• wired or infrared controllers,

• Optional WiFi for remote control,

• Possible integration with home automation systems via BACnet or Modbus .

• weekly programming

• Advanced modes: energy saving, minimum heat, automatic defrosting.

In some multi-unit residential buildings on the North Shore , this flexibility has made it possible to reconcile the needs of the occupants with the energy management requirements of the owner, without compromising on comfort.

Reliability, maintenance and peace of mind

The internal components, including the corrosion-resistant ProCore™ copper coils, are designed for durability in demanding environments. The standard warranty covers the compressor and parts for 12 years , with additional warranty options available depending on the terms and conditions.

At AirGreen, we always emphasize the importance of regular HVAC maintenance :

• filter cleaning,

• inspection of the integrated drain,

• verification of pressures and operating parameters.

These simple operations extend the life of the system, maintain its performance and reduce the risk of unexpected breakdowns in the middle of winter.

LogisVert subsidy and project profitability

This heat pump is eligible for the LogisVert provincial subsidy , which can reach up to $1,728 , depending on the applicable criteria. We assist our clients with all administrative procedures, from verifying eligibility to preparing the required documents.

By combining the subsidy, energy savings and improved comfort, the overall profitability of the project becomes particularly attractive, both for a primary residence and for a rental building.
