Two popular HVAC solutions, two very different approaches – but which one truly fits your home in Longueuil?
At AirGreen, we help families and homeowners in Longueuil every day choose the best heating and cooling (HVAC) system. And one of the questions we hear most often is: “Should I go with a ducted system or a wall-mounted heat pump?”
To answer in a clear, professional way tailored to the local reality, we’ve compiled the advantages, limitations, decision criteria, available grants, and most importantly, our first-hand experience from real installations carried out in Longueuil and on the South Shore of Montréal.
Understanding both systems: how they work and what makes them different
What is a ducted system?
A ducted system (often referred to as a concealed duct system) is a centralized setup that distributes warm or cool air throughout the home via a network of hidden ducts in walls or ceilings. The indoor unit is concealed, usually in an attic or false ceiling, which makes for a clean, discreet look.
This system can be paired with a central heat pump, often from brands like Goodman, Arcoaire, or Bosch, which we regularly install in homes across Longueuil.
Advantages:
-
Even air distribution throughout multiple rooms
-
Quiet operation (the unit is isolated)
-
Ideal for larger homes
-
Compatible with central ventilation and air exchangers
Disadvantages:
-
More invasive installation (ductwork required)
-
Requires technical space (attic or ceiling)
-
Higher upfront cost
What is a wall-mounted heat pump?
A wall-mounted heat pump (also called mini split) is a simpler, ductless solution with an indoor wall unit and an outdoor compressor. At AirGreen, we often recommend models like the Gree Extreme, the Fujitsu KZAH R-32, or the SHARP ZU1, which are especially efficient for single-family homes in Longueuil.
Advantages:
-
Quick, minimally invasive installation
-
Excellent energy efficiency (especially with R-32)
-
Lower purchase cost
-
Ideal for renovations, multi-unit dwellings, or specific rooms
Disadvantages:
-
Visible indoor unit
-
Less suitable for large homes
-
Air distribution is less uniform across several rooms
Case study: Single-family home in Longueuil
We recently helped a family in the Vieux-Longueuil area completely upgrade their HVAC system. The two-storey home with a finished basement already had partial ductwork in place.
After inspection and thermal analysis, our team presented two scenarios:
-
Install a Bosch BOVA36HDN1M20G central heat pump connected to a ducted system for optimal comfort throughout the home.
-
Install three Gree Extreme 12,000 BTU wall-mounted heat pumps (one per floor) for a zoned approach.
Final customer choice: They chose the ducted solution for its discreet aesthetic, balanced air distribution, and compatibility with a central humidifier. Thanks to the LogisVert program, they received a $5,460 rebate.
