Rated 4.5 out of 5 from 1,221 Google reviewsJCD in Downtown Montreal
Downtown Montreal sits on the southern slope of Mount Royal and holds most of the city's skyscrapers and many corporate headquarters. 109,509 people lived there in the 2021 Census, up 24.2% from 2016, so condo towers now stand beside older office buildings. HVAC work here is tower work: rooftop equipment, ductless units in condos and visits scheduled with building management. JCD services commercial rooftop units and residential systems in downtown buildings.

Homes and buildings in Downtown Montreal
Downtown is part of the Ville-Marie borough, where 97.6% of occupied dwellings are apartments and 56.9% are in buildings of five storeys or more. Montreal's assessment roll shows 46.5% of the borough's dwelling units in buildings built since 2001. A tower has little or no yard, so outdoor equipment goes on a roof or inside the building, and access is arranged with the building manager.

Before an outdoor unit goes in
Downtown falls under the Ville-Marie borough, which requires a permit for a permanent heat pump or air conditioner. Units are banned in a front yard and on a front balcony. On a flat roof, the unit must sit back from the façade by twice its height, and an acoustic screen may be required. Check the permit with the borough before installation; we size and place the unit to meet it.
