A central heat pump designed for our winters: stability, efficiency, and measurable comfort
In the field, in Montreal , Laval, and Longueuil , we see the same reality: a central heat pump isn't judged on a spec sheet, but on its ability to deliver consistent comfort when the weather becomes unpredictable (humid thaws, cold winds, freeze/thaw cycles, periods of dry cold followed by rain). The LG R32 | 2 Ton - 24,000 BTU Central Heat Pump has precisely this type of profile: a central system designed to combine 24,000 BTU cooling and robust heating, with modern efficiency principles and control options that integrate seamlessly with homeowners' habits.
At AirGreen , we install, commission, and maintain HVAC systems in single-family homes, duplexes/triples, ducted condos, and small residential buildings throughout the North and South Shores . For this LG model, the key benefits lie in very concrete aspects, those that truly make a difference in everyday life:
-
Seasonal performance , and not just “on paper”, particularly during the mid-seasons typical of Greater Montreal.
-
Integration into an existing (or adjusted) duct network , with intelligent airflow management to reduce temperature variations.
-
Installation quality : sizing, ductwork (conduits), drainage, power supply, commissioning and final adjustments.
-
The stability of comfort , that is to say the ability to avoid cycles that are too short, "forgotten" rooms and uncomfortable air sensations.
In other words: when the system is well chosen and well installed, you get a “calm”, stable comfort, without having to constantly adjust the thermostat.
What you are actually buying: a coherent set (exterior + interior)
This product is typically configured with an outdoor unit (KUSXB241A) and an indoor unit (KNSLB241A ) for a 2-tonne centralized solution. The system is recognized in the AHRI performance database and is ENERGY STAR® certified , including the Cold Climate designation, which directly appeals to local homeowners who want a central heat pump designed for our conditions.
In real life, this “set” is important: a central heat pump performs like a duo, where the outdoor unit does its job of compressing/transferring heat and the indoor unit manages air circulation, temperature control, filtration and comfort stability.
Key technical data (the ones that really matter in a home)
To avoid unclear comparisons, here are the benchmarks that most often come up in discussion during our home visits, particularly in Montreal , Laval , Longueuil , and in several municipalities on the North Shore and South Shore :
-
Cooling capacity : 24,000 BTU (2 tons) — a very common size for ducted houses and plexes when the building is well insulated or properly balanced.
-
Refrigerant : R-32 — a more modern choice, appreciated for its efficiency and for evolving industry standards.
-
Seasonal efficiencies : high SEER2 and HSPF2 values for this category — which, under good conditions, translates into reduced air conditioning consumption in the summer and better heating efficiency during several typical Montreal winter days.
-
Cold weather heating capacity : designed to maintain useful performance down to low temperatures; this is a key point for those who wish to limit the use of supplemental heating.
-
Noise level : the sound balance depends as much on the unit as on the installation (support, location, ducts, vibration, air return). When properly installed, a central system can remain discreet and stable.
-
Wi-Fi : optional — ideal for fine control, schedules, and more intuitive comfort management.
-
Warranty (compressor – parts – labor) : 10-10-0 years , with the possibility of additional options depending on conditions.
-
Provincial grant (LogisVert) : $2,100 (update indicated: November 26, 2025) — useful for optimizing the budget of a replacement project.
Key point: these figures only become truly “profitable” if the installation is designed to deliver the right airflow , to the right place, with controlled static pressure and consistent air returns.
Why the “central” location often remains the best choice in Montreal, Laval, and Longueuil
In several sectors of Greater Montreal (Villeray–Saint-Michel–Parc-Extension, Ahuntsic, Rosemont, Saint-Laurent, Verdun, as well as in Laval such as Chomedey, Duvernay, Laval-des-Rapides, or on the South Shore such as Brossard, Saint-Hubert, Boucherville, Varennes), the real estate reality often looks like this:
-
house or plex with existing ducts ;
-
distant rooms that lack air (bedrooms upstairs, colder basement, secluded office);
-
a level of comfort that varies according to the seasons;
-
owners who want a clear, sustainable solution, with reliable after-sales service.
A well-selected central heat pump allows you to:
-
consistent comfort : fewer differences between upper floors and ground floors, fewer “dead zones”.
-
simplified management : central thermostat, stable setpoint, fewer micro-adjustments.
-
a better strategy to reduce the use of auxiliary heating, especially in the mid-season.
-
a system that is often more “natural” for houses already designed around a network of ducts.
And most importantly: the central unit allows you to work on the air in a global way — temperature, circulation, filtration, humidity — instead of correcting it room by room.
AirGreen Installation: What we check before recommending this model
Installing a central heat pump is not simply a matter of "installing a unit." Our approach is based on control points that prevent most common problems and transform a good machine into an excellent system.
1) Actual sizing: the house decides, not the label
Yes, we're talking about 2 tonnes / 24,000 BTU , but we still approve:
-
the actual surface area and volumes (ceiling height, finished/unfinished basement);
-
insulation, windows, orientation, sunlight;
-
lifestyle habits (teleworking, closed rooms, frequent cooking, number of occupants);
-
the problem areas (master bedroom too hot in summer, basement too cold in winter);
-
the condition of the pipes (leaks, crushed sections, insufficient returns).
Incorrect sizing results in either short cycles (discomfort + wear) or a machine that struggles (higher fuel consumption + colder components). In both cases, the owner pays more for less comfort.
Our goal : to choose a format that promotes stability. A well-sized central system should be able to operate regularly, with logical cycles, rather than constantly switching on and off.
2) Ducts and static pressure: the key factor
At the facilities in Laval and on the South Shore , we often encounter:
-
air returns that are too small;
-
poorly positioned grids;
-
undersized secondary conduits;
-
junctions with air leaks (which end up “stealing” comfort from certain rooms).
The result: a high-performance heat pump becomes average in a home. This is where on-site expertise makes an immediate difference.
At AirGreen, we take a practical approach:
-
verification of the continuity of the conduits;
-
air return adjustments (often the key);
-
balancing of flow rates (so that each room receives its share);
-
reduction of losses and turbulence (comfort and noise).
What this changes : a house that stabilizes faster, less temperamental bedrooms, and more “uniform” comfort without overconsumption.
3) Cooling and humidity: summer comfort is not just a matter of temperature
In Montreal , summers are often humid, and many homeowners realize this when they already have a system:
-
a “sticky” sensation despite a low temperature;
-
stuffy air, poorer sleep;
-
damp basement or persistent odors.
A properly adjusted central heat pump can help tremendously, but it requires:
-
a well-designed drainage system (slope, siphon, access);
-
proper insulation on certain sections;
-
an airflow consistent with the desired dehumidification;
-
careful commissioning.
Summer comfort in our homes is often the sum of two things: cooling and drying the air . When dehumidification is well managed, the house feels cooler without necessarily turning the thermostat too low.
4) Control and integration: a simple interface, more predictable comfort
In a centralized system, control is at the heart of the experience. A poorly placed thermostat (or controller) can distort the entire system's behavior.
-
installed in a poorly ventilated corridor;
-
on a cold wall;
-
near a heat source (kitchen) or a draft.
We choose the location carefully and clearly explain best practices to the owner:
-
avoid extreme variations;
-
prioritize a stable instruction;
-
understand the settings that promote efficiency.
If Wi-Fi is added, smart schedules can also be set up, which are often very useful for families and for those who work remotely.
5) Electricity: safety, compliance and serviceability
A central system must be installed with a compliant, robust, and easily accessible power supply. In practice, this means:
-
correctly sized circuit breaker;
-
suitable wire gauge;
-
compliant protection;
-
clean, safe, durable installation.
Electrical compliance is a basic requirement. But quality of execution — clean, accessible, logical — also reduces delays and costs during any future service.
6) Commissioning: where a good system becomes excellent
Commissioning is a step that many underestimate. At AirGreen, it's an integral part of project quality. We validate:
-
operating parameters;
-
behavior in heating and air conditioning;
-
air pressure and flow rate;
-
balance of parts;
-
noise/vibration;
-
drainage and evacuation.
It is often at this stage that comfort is “finalized”: one room too hot, another too cold, an air return to adjust, a grille to optimize.
AirGreen case study: replacement of an aging system in Laval (2-tonne profile)
In a residential area of Laval , a homeowner contacted us about a common problem: the air conditioning was still working, but the heating was becoming erratic and the bills were rising. After inspection:
-
Generally good ductwork, but air return needs improvement;
-
thermostat poorly placed (inaccurate reading);
-
Device at the end of its life, unstable cycles.
We recommended a central 2-tonne solution, with adjustments to air return and balancing. Result observed after commissioning:
-
more stable temperature between ground floor and upper floor;
-
fewer “peaks” and rapid drops;
-
sensation of more constant air in mid-season;
-
Simpler thermostat management.
This scenario is common: the equipment matters, but the quality of the HVAC integration matters just as much.
Common mistakes to avoid with a central heat pump (and how we counteract them)
Mistake 1: keeping ducts “as they are”
Even if it works “more or less”, losses (leaks, insufficient returns, poorly balanced branches) turn your investment into a permanent compromise.
Our solution : pragmatic inspection, targeted adjustments, balancing. We correct what truly influences comfort.
Error 2: Ignoring the location of the thermostat/control
A poorly placed control means the house doesn't meet the set temperature. As a result, some rooms overheat, while others remain too cool.
Our solution : thoughtful placement, explanation of settings, and usage advice based on the reality of the building.
Mistake 3: Underestimating the importance of drainage
A poorly designed drain leads to avoidable overflows, moisture, and service calls.
Our solution : well-designed drainage, service access, and validation during commissioning.
Mistake 4: Believing that a subsidy compensates for a bad choice
The LogisVert subsidy helps, but it never replaces a suitable choice for the building and a proper installation.
Our solution : select correctly, install properly, then optimize to achieve real performance.
Mistake 5: Neglecting HVAC maintenance of a central system
Many problems (reduced flow rates, decreased performance, noise, uneven comfort) stem from neglected maintenance.
Our solution : a simple and clear maintenance program: inspection, cleaning, functional check, and concrete recommendations.
