If you’ve been exploring home cooling options, you’ve probably come across the term ductless AC system—also called a mini-split. But what does ductless AC mean, and more importantly, is it a smart choice for your home in Mississauga?
This blog covers everything: how ductless AC works, its features, cost, efficiency, and where it’s best installed. Whether you’re dealing with a hot attic, an older home with no ductwork, or simply want room-by-room comfort, this might be exactly what you need.
What Is a Ductless AC System?
A ductless air conditioning system, or mini-split, is a modern cooling setup that doesn’t rely on ducts to deliver air throughout your home. Instead, it uses one outdoor unit and one or more indoor units to cool specific areas, also called zones.
Each indoor unit is typically mounted on a wall and connects to the outdoor condenser via refrigerant lines and electrical wiring, all running through a small hole in your wall.

How Does Ductless AC Work?
The ductless system cools air in a more targeted and efficient way. Here’s a simple breakdown of how it works:
- Indoor air handler draws warm air from the room.
- Air is cooled using a refrigerant cycle.
- The cooled air is released directly into the same space.
- Heat is pushed outside via the connected condenser unit.
Because each indoor unit works independently, you can cool one room or multiple zones without wasting energy on unused spaces.

A ductless system means:

How Much Is a Ductless AC?
The cost depends on several factors:
- Number of zones

Want lower hydro bills? Go ductless.
Are Ductless AC Units Quiet?
Yes—whisper quiet. Indoor units usually operate around 20–30 decibels, which is quieter than a standard conversation. This makes them ideal for:
- Bedrooms
- Nurseries
- Home offices
- Reading rooms
You’ll hardly know it’s running—but you’ll definitely feel the comfort.
Can Ductless AC Be Installed in Attic Spaces?
Yes, it’s one of the best solutions for cooling finished attics, where running ductwork is next to impossible. Wall-mounted or sloped-ceiling units fit in tight areas and cool efficiently without taking up floor space.
We frequently install ductless systems in attics across Mississauga, especially in:

Can I Install Ductless AC Myself?
Technically? Maybe. But it’s not recommended.
Ductless installation involves:
- Electrical work
- Refrigerant handling
- Proper line sizing and vacuuming
- Wall mounting and secure sealing
DIY could void warranties or damage components. Plus, Mississauga building codes may require certified HVAC professionals.
