FORESTAIR E-23 Heat Pump | 12,000 BTU | Installation in Montreal & Montérégie

A wall-mounted heat pump designed for Quebec's climate and residential realities

At AirGreen, we have been installing and maintaining HVAC systems for many years in Montreal , Laval , Longueuil , on the North Shore and the South Shore . Over time, one thing has become clear: a large proportion of homeowners are primarily looking for a reliable wall-mounted heat pump that is stable in winter, quiet in everyday use, and without unnecessary technological features that unnecessarily inflate the bill.

The FORESTAIR E-23 | 12,000 BTU heat pump precisely meets this expectation. It doesn't aim to position itself as a complex, high-end model, but rather as a balanced solution designed to offer consistent performance, predictable operation, and real comfort in well-defined residential spaces.

This article presents an in-depth analysis of the FORESTAIR E-23, based on our field experience: its actual performance in heating and cooling, the installation contexts in which it excels, common mistakes to avoid, and why this model remains a relevant choice for many residential projects in Quebec.

The actual positioning of the FORESTAIR E-23 | 12,000 BTU

A heat pump designed for specific areas

The FORESTAIR E-23 12,000 BTU is a wall-mounted heat pump designed to efficiently serve specific areas, rather than an entire large house. It is particularly well-suited for:

• an urban condo

• a medium-sized apartment

• an open, well-insulated ground floor

• a home office

• a four-season chalet

• a specific area in a single-family home (floor, extension, colder section)

With its nominal capacity of 12,000 BTU in air conditioning and its heating capacity maintained down to -25 °C , it is very well suited to the climatic conditions of Montreal and the Montérégie , when the sizing is done correctly.

At AirGreen, we always emphasize one essential point: a wall-mounted heat pump delivers excellent results when used for its intended purpose . The FORESTAIR E-23 perfectly illustrates this point.

Detailed analysis of technical performance

Behavior during winter heating

One of the key criteria for our customers remains winter performance. The FORESTAIR E-23 offers:

• Heating function down to -25°C

• 10,400 BTU at -8°C , which covers the majority of winter needs in urban areas.

• 9,100 BTU at -15°C , allowing for stable comfort without a sudden drop in performance

In practice, this means that for a well-insulated condo or floor, the heat pump continues to play a central role in heating for much of the winter, reducing the use of electric baseboard heaters or other supplementary sources.

Air conditioning efficiency and summer comfort

In air conditioning, the FORESTAIR E-23 stands out because of:

• a homogeneous air distribution

• stable operating cycles , avoiding excessively frequent starts and stops

• consistent comfort , even during periods of hot and humid weather

In several projects carried out in Montreal , we have observed a notable improvement in interior comfort, particularly in units facing due south or located on the upper floors of condo buildings.

Noise level and quality of life

Acoustic comfort is an often underestimated aspect. With an interior noise level ranging between 29 and 45 dB(A) , the FORESTAIR E-23 is very well suited:

• to the bedrooms

• to teleworking spaces

• at the open salons

During our installations on the South Shore , several clients mentioned that they literally forgot the heat pump was running, a clear indicator of a system well suited to daily use.

Concrete feedback from our AirGreen installations

Real-life cases observed in the field

We have installed the FORESTAIR E-23 12,000 BTU in a wide variety of settings:

• Condo in Longueuil (approximately 900 sq ft)
  Wall-mounted installation in an open-plan living room/kitchen. Result: stable temperature, low noise, constant comfort summer and winter.

• Single-family home in Laval
  Used as a dedicated solution for the upper floor, complementing an existing central system. The objective was to correct temperature differences in the rooms, which was achieved in the first season.

• Apartment in East Montreal
  Replacement of an old, inefficient wall-mounted air conditioner. The customer noticed an immediate improvement in comfort and a reduction in electricity consumption during the summer.

These examples illustrate a key point: when the FORESTAIR E-23 is correctly selected and installed, it delivers exactly what it promises.

Common mistakes to avoid with a 12,000 BTU wall-mounted heat pump

Even a good product can give poor results if used incorrectly. Here are the most common mistakes we encounter:

• Choosing a 12,000 BTU unit for an area that's too large , hoping to compensate with continuous operation

• Installing the unit without taking into account the natural air circulation

• Neglecting the impact of closed doors between rooms

• Assuming that a wall-mounted heat pump will completely replace a central system

• Installing the unit too high or in an obstructed location

At AirGreen, we clearly explain these limitations before installation, in order to avoid any long-term disappointment.
