LG Central Heat Pump LGRED R32 | 2.5 Tons - 30,000 BTU

A power plant designed for Greater Montreal: consistent comfort, better air management, and real performance in winter

When you talk about central heat pumps in the Montreal area, it's not a "standard" purchase. Here, the weather imposes a very specific reality: humid summers, increasingly frequent heat waves, deceptive thaws, followed by weeks of dry cold and winds that literally sweep through neighborhoods. In Laval , on the North Shore or the South Shore , you see the same challenges, but with different buildings and lifestyles: houses with finished basements, renovated duplexes, newer constructions with existing ductwork, or older properties where the air distribution has been modified over the years.

The LG LGRED R32 Central Heat Pump | 2.5 Tons - 30,000 BTU fits perfectly into this context: a centralized HVAC solution that aims for stability, uniformity, and ease of operation, without sacrificing performance. It's a particularly attractive option for homeowners who want:

• Consistent comfort across multiple rooms and floors

• A central air conditioning system that doesn't leave certain areas "behind"

• Efficient heating in the mid-seasons and winter

• Smarter humidity management, often the forgotten element of comfort

• A solution that integrates well with an existing (or optimized) duct network.

Who is a 2.5 tonne (30,000 BTU) capacity intended for in Greater Montreal?

A 2.5-tonne / 30,000 BTU unit is often suitable for:

• single-family homes where the goal is uniform air conditioning and heating.

• Renovated duplex/tripleplexes with ductwork (or a dedicated building section)

• properties where the old furnace or heat pump becomes unstable, noisy, or expensive to operate

In areas like Rosemont , Villeray , Ahuntsic , Saint-Laurent , Le Sud-Ouest , and Verdun , a typical situation is very common: a house improved in stages (new windows, partial insulation, renovated basement), but an HVAC system that remains “stuck in the past.” In Laval (Chomedey, Fabreville, Duvernay), it’s frequently the opposite: the house may be relatively new, but the air distribution has never been optimized for comfort (excessive airflow in some areas, undersized return ducts, poorly positioned grilles).

At AirGreen , our approach isn't to "sell power," but to confirm a capacity that's consistent with the building. Proper sizing prevents:

• short cycles (discomfort + wear)

• insufficient dehumidification in summer

• temperature differences between floors

• an energy bill that doesn't match the promises

What makes the LG LGRED R32 interesting: system logic, control, and "feelable" comfort

1) The choice of R-32 refrigerant: a modern approach

R-32 is a refrigerant adopted in several modern vehicle lines to reduce environmental impact compared to some older refrigerants. For a vehicle owner, this isn't just a "technical" detail: it's an indicator that they're using a recent platform designed for current requirements.

At AirGreen, this also means very strict installation discipline: airtightness, quality of connections, proper procedures, and rigorous commissioning. In the real world, this is what separates a "decent" heat pump from one that remains reliable, quiet, and stable for years.

2) A central heat pump is not a wall-mounted unit: it provides overall comfort

A wall-mounted unit might be perfectly adequate for a condo or a specific area. But a central unit aims for something else entirely: balanced comfort in every room , including those we often forget about.

• rooms away from each other

• basement office

• stairwell

• rooms above the garage

• areas exposed due west in summer

This is exactly where the 2.5 tonne / 30,000 BTU format becomes strategic: it can support a real load across multiple zones, especially when the house is occupied and daily life creates variations (cooking, showers, appliances, gatherings, doors opening, etc.).

3) Humidity management: summer comfort, Montreal style

Many people associate air conditioning with “lowering the temperature.” However, in Montreal , summer comfort is often a matter of dehumidification . When the air is humid:

• 24°C may seem heavy

• Basement floors can become cold and damp

• some areas smell musty

• Sleep deteriorates, even if the temperature is “correct”.

With a properly adjusted central heat pump, the goal is not just to be cold: it is to have drier and more stable air , which often allows you to be comfortable at a slightly higher temperature (and therefore more economical).

HVAC Installation: What We Do Differently at AirGreen (and Why It Makes All the Difference)

Installing a central heat pump is not simply a matter of “placing a unit and leaving.” A successful installation rests on three pillars:

1. Building mechanics (ducts, returns, air circulation)

2. The external layout (clearances, drainage, noise, access)

3. Commissioning (adjustments, checks, performance validation)

Step 1: Reading the ducts and airflow (the most underestimated point)

In Greater Montreal, the conduit networks are rarely perfect. We often see:

• Air returns that are too small (noise, discomfort, reduced efficiency)

• uneven distribution of air vents (some rooms over-supplied, others neglected)

• conduits added without any logic during renovations

• restrictions behind finished ceilings

At AirGreen, we take the time to understand the system. Because even the best central heat pump in the world, on a poorly balanced system, will give frustrating results. And when a customer says "my unit is noisy," very often it's not the brand: it's the air ductwork that's forcing the machine to work under poor conditions.

Step 2: Outdoor location — acoustic comfort and actual efficiency

In Longueuil , Boucherville , Brossard , Laval and Montreal , outdoor locations must adhere to winter guidelines:

• prevent ice and snow from blocking ventilation

• ensure proper clearance around the unit

• maintain easy access for maintenance

• limit sound reflection off walls that are too close

A heat pump that "breathes" properly is one that maintains its efficiency and defrosts correctly. And a smartly installed unit also provides peace of mind: no surprises during a cold snap or storm.

Step 3: Commissioning and adjustments (where expertise is needed)

A control unit needs to be adjusted. Period.
We specifically approve of:

• the stability of the airflow

• the consistency of thermostat settings

• the logic of supplementary heating, if applicable

• the quality of condensate drainage

• air conditioning and heating operation

This is often where real-world experience makes all the difference: a house isn't a brochure, and a homeowner doesn't live in "laboratory conditions." Our role is to make the system logical to use , stable, and comfortable in real life.

Two typical stories (AirGreen style): Rosemont and Fabreville, two realities, one same goal

Case 1 — Duplex in Rosemont: uneven air conditioning, heavy basement, unstable comfort

In a renovated duplex, the family complained about two things:

• The floor became stifling as soon as it got hot.

• The basement remained damp, with a feeling of heavy air.

The previous system provided strong but poorly distributed airflow. We first corrected the return air logic and the overall system balance, then installed the LG LGRED R32 2.5-ton – 30,000 BTU central heat pump, aiming for more stable, less aggressive, and more consistent operation. After installation:

• the temperature has become uniform

• humidity was better controlled

• The perceived noise decreased because the air circulated better.

This type of project is extremely common in Montreal: comfort depends not only on power, but also on distribution.

Case 2 — House in Fabreville (Laval): replacement of an aging system, objective “zero worries”

The requirement here was simple: to replace an unstable system with a simple user experience.

• a clear control

• constant comfort

• a clean and sustainable installation

We optimized the outdoor location (clearance and drainage), secured access points, and verified electrical consistency. The result: a system that better meets everyday needs, without any "temperamental" zones. This client, like many others, particularly appreciated that the house is more stable, summers are more comfortable, and in winter, the system no longer feels like it's "on the edge."

Common mistakes with a central heat pump (and how to avoid them)

Mistake 1: Underestimating the importance of air return

An air return that is too small or poorly positioned creates:

• noise

• inconsistent comfort

• a decrease in efficiency

• faster wear

We often correct existing networks simply by bringing the system back to a logic of healthy air circulation.

Mistake 2: Installing the outdoor unit in a “convenient corner”

A practical space today can become a problem in winter: snow, ice, air recirculation, difficult access for maintenance. At AirGreen, we think about "Quebec winters" right from the planning stage.

Error 3: leaving the settings on “default”

A central heating system must be suitable for the home. Otherwise:

• Summer: poor dehumidification

• Winter: discomfort and unnecessary cycles

• All year round: noise or unusually high bill

Mistake 4: Not planning maintenance from the outset.

A central system is an investment. To maintain its performance, you need to consider the following from the outset:

• accessibility of filters

• accessibility of key components

• clean drainage

• service area

Maintenance and best practices: maximizing performance and lifespan (practical advice)

Filtration: simple, but crucial

The filter is often the "small part" that causes big problems. A neglected filter can lead to:

• decrease in airflow

• noise increase

• reduced efficiency

• discomfort

At AirGreen, we explain it clearly:

• what type of filter to use

• how often to check it

• which changes depending on the season (summer is dustier, winter is drier)

Seasonal cleaning and inspection

A central heat pump performs best when:

• The outdoor unit is clear.

• leaves and debris do not accumulate

• the drainage remains free

• the system is checked regularly

Annual maintenance is often what avoids surprises: a heat pump does not "break down by magic", it almost always gives warning signs (noise, strange cycles, decreased comfort, humidity).
