Ductless heat pumps are rapidly gaining popularity in Ottawa as homeowners look for efficient and flexible ways to heat and cool their homes. These systems offer a modern solution for homes without existing ductwork, provide excellent energy savings, and allow for precise temperature control in different rooms. In this article, we will explore the most frequently asked questions regarding ductless heat pump installation, covering everything from costs and benefits to maintenance, rebates, and the installation process.

What is a ductless heat pump?
A ductless heat pump is an advanced HVAC system designed to provide both heating and cooling without the need for traditional ducts. Unlike central HVAC systems that rely on ductwork to distribute air, ductless heat pumps use refrigerant lines to connect an outdoor compressor unit to one or more indoor air-handling units. These indoor units, often mounted on walls or ceilings, allow for individual room control, a feature known as zoned heating and cooling.
The key components of a ductless system include:
- Outdoor compressor/condenser: This unit absorbs and releases heat depending on the season.
- Indoor air-handling units: These are responsible for blowing conditioned air into the rooms.
- Refrigerant lines: These connect the indoor and outdoor units and allow heat transfer.
- Remote control or smart thermostat: Many systems now offer app-based controls for added convenience.
Because these systems do not require ductwork, they are particularly beneficial for older homes, home additions, or areas where running ducts is impractical or cost-prohibitive.
