Reduce the Impact of Urban Heat with the Right Heat Pump, Properly Installed
When we talk about staying comfortable during the summer in Montréal, the conversation often turns to heatwaves, lack of urban trees… and the struggle to keep our homes cool. The urban heat island effect, especially intense in highly paved neighbourhoods, can raise the perceived temperature by 5 to 8°C higher than in greener or rural zones. In this context, a well-chosen and well-installed heat pump becomes not just a comfort tool, but also a sustainable and economical solution to cool your urban home or condo effectively.
At AirGreen, we’ve adapted our HVAC installation practices to meet the real needs of clients living in these affected zones. Here’s how.
What is an Urban Heat Island and Why Should You Care?
An urban heat island (UHI) is a densely built-up area where the ambient temperature is significantly higher than surrounding regions. The main causes include:
-
High density of concrete and asphalt (which retain heat)
-
Lack of vegetation and green spaces
-
Concentrated vehicle traffic and human activity
-
Reduced natural cooling, even at night
Neighbourhoods like Rosemont–La Petite-Patrie, Le Plateau–Mont-Royal, or Hochelaga-Maisonneuve often face suffocating temperature spikes in summer.
Under these conditions, a basic fan or portable A/C just won’t cut it. A wall-mounted or central heat pump becomes the ideal solution… as long as it’s the right fit.
Which Heat Pump to Choose for a Hot Urban Climate?
Key Criteria for Effective Urban Cooling
1. Proper Cooling Capacity (BTU)
Your system needs to be sized precisely. Too small = inefficient. Too big = uncomfortable and wasteful. At AirGreen, we perform an on-site thermal assessment to evaluate heat gains and losses related to the urban environment.
2. High Energy Efficiency (High SEER)
A SEER rating of 17 or higher is recommended to combat urban heat while keeping electricity consumption low. Our top models like the Fujitsu KZAH R-32 or the Bosch BOVA reach up to SEER 20.
3. Inverter Technology
This allows fine-tuned temperature control without sudden changes, which is essential when it's very hot and your walls keep radiating heat well into the night.
4. Low Noise Operation
In dense urban areas, noise matters. Our models like the Gree Sapphire or the Sharp ZU1 are designed to run ultra-quietly, even at full capacity.
AirGreen Case Study: Cooling a Condo in the Heart of the Plateau
A client on Saint-Joseph Street, living on the top floor of a condo, suffered from severe overheating in the summer. The unit faced full south, with little shade and a typical black gravel roof—classic heat island conditions.
We installed a 24,000 BTU Sharp ZU1 wall-mounted heat pump, a high-efficiency model, equipped with an outdoor temperature sensor to anticipate heat spikes. The results:
-
Indoor temperature stabilized at 23°C even when it hit 35°C outside
-
Electricity bill dropped by 22% over 3 months
-
Outdoor noise reduced to 23 dB
Smart Installation: Our Best Practices for Urban Settings
At AirGreen, we adapt each installation to suit the specifics of the building:
-
Air outlet orientation to avoid recirculating hot air
-
Anti-vibration mounts for shared walls
-
Concealed ductwork to preserve the building’s aesthetics
-
Optimized airflow design based on room layout and movement patterns
Every installation is preceded by a comprehensive diagnostic, essential in urban housing.
LogisVert Grants and Energy Efficiency
Did you know that heat pumps installed as replacements for electric systems (like baseboard heaters) are eligible for LogisVert grants?
-
Up to $2,172 for a single-zone wall-mounted heat pump

Common Mistakes to Avoid in Urban Areas
-
Underestimating solar gains (flat roof, large windows)
-
Choosing a unit not suited to actual use
-
Skipping annual maintenance, which is crucial during heatwaves
-
Ignoring ambient noise: budget models are often too loud for dense areas
