Air Conditioning Installation in Gatineau
Outaouais summers bring stretches of heat and humidity that most older homes were never designed to handle. Chauffage Climatisation Gatineau installs central air conditioning and ductless cooling systems sized for your home, not just your budget.

Central AC versus ductless cooling
If your home already has a forced-air furnace and ductwork, adding a central air conditioner is usually the simplest path, using the same ducts and thermostat. Homes without ductwork, or with rooms that never cool evenly, are often better served by a ductless system that cools specific zones directly.
- Central AC added to existing furnace ductwork
- Ductless wall units for additions, basements or upper floors
- Whole-home multi-zone ductless systems
- Combined heating and cooling through a heat pump
Dealing with humidity
Cooling capacity and dehumidification aren't the same thing. An oversized air conditioner can cool a room quickly without properly removing humidity, leaving a space that feels cold but clammy. We size equipment to run longer cycles at the right capacity, which does a better job managing humidity through a typical Outaouais summer.
Working with older ductwork
Many Hull and Gatineau homes have ductwork that was never designed for air conditioning loads. Before installing a central system, we check duct sizing, insulation and sealing, since leaky or undersized ducts can undercut the performance of an otherwise well-matched system.
How it works
- 01
Home evaluation
We assess your ductwork, electrical service and cooling needs room by room, including any areas that currently run hot.
- 02
Equipment recommendation
You get a clear comparison of central versus ductless options based on your home's layout and existing systems.
- 03
Installation and commissioning
The system is installed, refrigerant lines and electrical connections are completed, and airflow is verified before we walk you through operation.
Frequently asked questions
Can I add central air to my existing furnace?
In most cases yes, as long as the ductwork and furnace blower can support the added airflow. We check this during the assessment before recommending equipment.
Is ductless cooling enough for a whole house?
A multi-zone ductless system can cool an entire home, especially one without existing ducts, but the number of heads needed depends on room layout and how the home is used.
Why does my house feel humid even when the AC is running?
This is often a sign the system is oversized and cycling too quickly to remove moisture from the air. Proper sizing addresses this directly.
Can one system handle both heating and cooling?
Yes, a heat pump provides both, either through a ductless system or connected to existing ductwork, and is worth considering if you're already planning to replace your air conditioner.
Do older Gatineau homes need duct upgrades for AC?
Some do. Undersized or leaky ducts reduce the benefit of even a well-matched air conditioner, so we inspect ductwork condition before quoting a central installation.
