Ductless Air Conditioning

Ductless Air Conditioning

It's never been easier to control your Toronto, ON, home's temperature thanks to ductless air conditioning systems. These systems are also called mini split ductless air conditioners or ductless heat pumps, offering heating and cooling functions.

Many Toronto homeowners install ductless air conditioning units because of their efficiency and affordability. Before you make a decision on the best way to maintain comfort in your Ontario home, it's important to know how ductless systems heat and cool a home.

Ductless Heating & Cooling Advantages


Easy Installation

Mini-split ductless air conditioners offer a less invasive installation process compared to central air systems. Ideal for remodeled or newly finished areas in your home, they provide flexible design and installation choices. The absence of bulky ductwork means more space in your home for your design and comfort needs.

Energy Efficiency

Traditional air conditioners with leaky ducts can waste up to 30% of cooled air. Ductless mini-splits, on the other hand, conserve energy, outperforming window units, portable air conditioners, and space heaters in efficiency. This translates into significant savings on your monthly electricity and natural gas bills, making the system pay for itself over time.

Cleaner Indoor Air

Ductless systems not only cool and heat your home but also boost indoor air quality. Each cycle of heating or cooling involves air passing through a filter, trapping particles like pollen, dust, and dander. This leads to cleaner, healthier air and a tidier home environment.

Smaller Carbon Footprint

Ductless mini-split systems allow you to heat or cool specific zones in your home. With the ability to control up to eight zones from one outdoor unit, you can avoid heating or cooling unused areas. Programmable or smart thermostats for each zone, controllable via an app, mean more efficient energy use and a smaller carbon footprint.

Customized Climate Control

Ductless mini-splits cater to individual temperature preferences, allowing different zones to be set to varying temperatures. This means you can enjoy a cooler bedroom while another family member keeps their space warmer, ensuring comfort for everyone.

Flexibility and Space Saving

The compact size and flexibility of ductless mini-split systems allow for an unobtrusive fit into your home's design. Without the need for extensive ductwork, you reclaim space in your home, offering more freedom in design and layout choices.

How does Ductless Air Conditioners heat a house?

Heat pumps use a refrigerant to transfer heat from one place to another. These refrigerants work well in hot, moderate and cold climates.

In the winter months of the year, the heat pump's refrigerant absorbs heat energy from the outdoor air. It can do this even if the temperature drops to an extremely cold level.

The heat energy from the outdoor air is transferred to the refrigerant and pumped into your home. The indoor unit's fan blows cool air from your home across the coil, which contains the warm, compressed refrigerant.

In the summertime, the heat transfer cycle is reversed. The unit's reversing valve makes this possible. The indoor unit's coil functions as an evaporator and contain cold refrigerant.

As the fan blows warm air from your home across the cold coil, the temperature of the air drops. Moisture condenses out of the air as it cools.

The unit's condensate line collects this moisture and drains it into your home's wastewater system. The refrigerant absorbs the heat energy from your home's air. A pump pushes the warm refrigerant back to the outdoor unit, where it releases the heat energy to the outdoor air.

Ductless cooling systems are a greener alternative to central air conditioners that rely on ducts for air distribution.
