FORESTAIR E-23 Heat Pump | 9,000 BTU | Installation in Montreal & Montérégie

A wall-mounted heat pump designed for the realities of Quebec homes

At AirGreen, we install hundreds of wall-mounted heat pumps each year in a wide variety of settings: urban condos, duplexes, single-family homes, multigenerational housing, home offices, and small commercial spaces. The FORESTAIR E-23 9,000 BTU heat pump is one of the models we recommend when the client's expectations are clear: reliable winter heating , efficient cooling , simple operation , and controlled overall cost , without unnecessary frills.

This model is particularly well-suited to small to medium-sized homes in Montreal , Laval , Longueuil , and on the North and South Shores, where space is sometimes limited and installation constraints demand a precise approach. The E-23 series is distinguished by its design focused on thermal stability, consistent performance, and intuitive everyday use.

Understanding the actual positioning of the FORESTAIR E-23 9000 BTU

A pragmatic approach to HVAC comfort

The FORESTAIR E-23 isn't designed to impress with exaggerated promises or superfluous certifications. Instead, it's aimed at homeowners who want a functional wall-mounted heat pump capable of providing reliable heating down to -25°C , while maintaining stable air conditioning during the increasingly hot and humid summers of Greater Montreal.

In many projects carried out by AirGreen, this model has been chosen as:

• The main solution is in well-insulated homes.

• complementary system to reduce the use of electric baseboard heaters

• replacement of old wall-mounted or portable air conditioners

This flexibility of use explains why it remains relevant despite the absence of provincial subsidies.

Detailed technical data – what we analyze before each recommendation

Before installing a wall-mounted heat pump, our technicians always assess whether the technical specifications are truly suitable for the home. For the FORESTAIR E-23 9,000 BTU , here are the parameters that most frequently come up in our analyses:

• Cooling capacity : 9,000 BTU

• Heating capacity down to : -25 °C

• Heating capacity at -8°C : 8,800 BTU

• Heating capacity at -15°C : 9,000 BTU

• Refrigerant gas : R-410A

• Electrical voltage required : 220 V

• Airflow (CFM) : optimized for uniform distribution in closed and semi-open rooms

• Interior noise level : 29 to 43 dB(A) depending on the selected speed

• Outdoor noise level : 53 dB(A)

• Built-in WiFi : included, no additional module required

• Model numbers :

  • Indoor unit: FGH-09ES/E23-I

  • Outdoor unit: FGH-09ES/E23-O

• Manufacturer's warranty : 10 years on the compressor, 10 years on parts

These elements make it possible to accurately predict the behavior of the system, both in periods of extreme cold and in the midst of a heatwave.

Energy performance explained under real-world conditions

Concrete interpretation of efficiency indicators

The efficiency values ​​of the FORESTAIR E-23 reflect consistent performance , without excessive variation depending on the season:

• SEER2 : 23.03

• HSPF2 : 18.515

• EER2 : 14.02

• COP at -8 °C : 3.2

In practical terms, this means that for every kilowatt of electricity consumed, the heat pump delivers a significantly greater amount of heat, even when temperatures drop below zero. In residential areas of Laval , Longueuil , and the Montérégie region, many customers have noticed a significant decrease in their winter electricity consumption after installation, particularly when baseboard heaters were no longer running continuously.

It's important to note that this model is not ENERGY STAR certified and is not eligible for LogisVert subsidies . At AirGreen, we make this clear from the outset to avoid any disappointment. We recommend the E-23 when the primary criterion is functional performance , not maximizing financial assistance.

HVAC Installation: The AirGreen Difference in the Field

Complete analysis before installation

Before any wall-mounted heat pump installation , our teams conduct a detailed assessment of the building:

• exact area to be served

• ceiling height

• room layout (closed, semi-open, corridors)

• level of insulation of exterior walls

• orientation of the dwelling and exposure to the sun

• condominium constraints or municipal regulations

In several condos in Montreal and on the South Shore , the FORESTAIR E-23 was chosen precisely for its compact dimensions , facilitating discreet integration without major modification of the walls or facade.

Installation quality and durability

A properly installed heat pump offers stable performance over the long term. At AirGreen, we pay particular attention to:

• the exact length of the refrigeration piping ( 1/4 – 3/8 in )

• the quality of the wall mounts and anti-vibration mounts

• the sealing of wall penetrations

• the slope and drainage of the condensation pipe

• the precise configuration of the air diffusion flaps

These details, often overlooked, have a direct impact on acoustic comfort, system longevity, and customer satisfaction.

Examples of concrete installations carried out by AirGreen

3½ condo in Montreal (Rosemont–La Petite-Patrie)

Customer looking to replace a noisy and inefficient portable air conditioner. After installing the FORESTAIR E-23:

• homogeneous temperature in the main area

• Significant improvement in nighttime comfort thanks to the low noise level

• marked reduction in the use of electric baseboard heaters

Semi-detached house in Boucherville

Setting up a home office located in the basement:

• maintaining a stable temperature even in extreme cold

• Daily use of WiFi control

• better humidity management in summer

Duplex in Laval

Adding an E-23 to a secondary residence:

• independent control of heating and air conditioning

• electricity consumption better distributed

• Tenant satisfaction from the very first winter season

This feedback from the field allows AirGreen to refine its recommendations and avoid sizing errors that are common in the HVAC market.

Points to consider before choosing the FORESTAIR E-23

The FORESTAIR E-23 9000 BTU heat pump is particularly suitable when:

• the area is clearly defined
