A high-performance HVAC solution tailored to Montreal's realities
At AirGreen, every HVAC installation is an opportunity to demonstrate our expertise on the ground, particularly in urban neighborhoods like Villeray–Saint-Michel–Parc-Extension, where technical constraints are often unique. We recently completed the full installation of a 3-ton MIDEA EVOX G3 central heat pump in a typical single-family home in the area, addressing specific challenges related to space, existing ventilation, and the client's energy requirements.
Customized intervention in a dense urban environment
Initial analysis and client needs
The owner wanted to replace an old, inefficient central system, consisting of an aging air conditioner and an energy-intensive electric heater. The objective was clear:
- Reduce energy costs
- Improve thermal comfort in both winter and summer
- Modernize the installation with an ENERGY STAR® certified energy-efficient solution
- Take advantage of available subsidies in Quebec
After an on-site technical evaluation, we confirmed that the 3-ton (36,000 BTU) MIDEA EVOX G3 was perfectly suited to the area and the configuration of the existing ducts.
Technical challenges encountered
This project involved several constraints typical of the sector:
- Restricted space for the outdoor unit, in close proximity to a wall and a staircase
- Limited access to the basement for the indoor unit
- Existing ductwork requiring airflow optimization
- Management of condensate drainage in a compact environment
Our team precisely adapted the installation, adhering to the strictest standards in the HVAC industry in Montreal.
