Wall-Mounted Ductless Heat Pumps
Wall-mounted ductless heat pumps are a practical fit for homes without ductwork, additions, and rooms that never quite reach the right temperature. Chauffage Climatisation Gatineau installs single and multi-zone systems across Gatineau, Aylmer and the surrounding area with attention to where the head actually goes, not just how many units you buy.
Single-zone versus multi-zone
A single-zone system connects one outdoor unit to one indoor head, ideal for conditioning a specific area such as a basement, addition or main living space. A multi-zone system connects several indoor heads to one outdoor unit, letting you heat and cool multiple rooms independently, though each zone draws from a shared outdoor capacity.
- Single-zone for one problem room or small addition
- Multi-zone for whole-home coverage without ductwork
- Independent temperature control per indoor head
- Outdoor unit sized for combined zone demand
Where the indoor head goes
Placement affects both comfort and how the unit looks in the room. A head mounted too close to a corner or above a doorway can create uneven airflow, while poor placement relative to windows can mean the unit works against cold drafts instead of the room's actual heat loss. We plan placement around your furniture layout and the room's real heat loss points, not just the easiest wall to mount on.
Winter condensate and outdoor unit setup
During defrost cycles, the outdoor unit produces meltwater that needs somewhere to go. In our climate, an outdoor unit set directly on the ground or too close to a wall can end up sitting in ice by mid-winter. We install outdoor units on proper stands or brackets, with condensate managed away from walkways and foundations.
How it works
- 01
Room-by-room review
We look at which rooms need coverage, where furniture and windows sit, and how many zones the home realistically needs.
- 02
Placement and equipment plan
Indoor head locations and outdoor unit position are planned together, along with line set routing.
- 03
Installation and testing
Units are mounted, wired, and refrigerant lines connected and tested for proper charge and airflow before handover.
Frequently asked questions
How many indoor heads do I need?
It depends on how many rooms need independent temperature control and how they're currently heated. Some homeowners only need one head for a problem area, while others cover most of the home with a multi-zone system.
Does placement of the indoor unit really matter?
Yes. Airflow patterns, nearby windows and furniture placement all affect how evenly a room actually feels conditioned, so we plan placement rather than defaulting to the nearest wall.
What happens to the outdoor unit in winter?
It continues running and periodically defrosts to clear frost from the coil, producing meltwater. We mount units on stands or brackets so ice and snow don't interfere with operation or drainage.
Can I add more zones later?
Sometimes, if the outdoor unit has spare capacity, but multi-zone systems are generally more efficient to plan for all zones from the start. We discuss this if you expect to add heads down the road.
Are wall units noisy?
Indoor heads run quietly under normal conditions; unusual noise typically points to an installation or maintenance issue rather than a design flaw.
