Not every home has ductwork — and not every home needs it. Ductless mini-split systems give you precise, room-by-room temperature control without the cost and disruption of installing ducts. They're one of the fastest-growing HVAC options in Ontario, and for good reason.

A ductless system connects a compact outdoor compressor to one or more indoor wall units through a small conduit. Each indoor unit has its own thermostat, so you can cool the bedrooms at night without running the living room, or heat only the rooms you're using during the day. That kind of control adds up to real energy savings.

What a lot of homeowners don't realize is that ductless mini-splits aren't just air conditioners — they're heat pumps. Modern cold-climate models from Mitsubishi, Daikin, and Fujitsu produce efficient heat down to -25°C, making them a legitimate heating option for Ontario winters. In a well-insulated home, a mini-split can handle primary heating. In older homes, it works great alongside your existing furnace.

Relica Comforts installs single-zone and multi-zone ductless systems across the GTA to Barrie. We handle everything from the initial assessment to the final commissioning, and we help you with rebate applications so you can take advantage of available incentives.

Why Homeowners Choose Ductless

No Ductwork Needed

Mini-splits connect an outdoor unit to wall-mounted indoor heads through a small refrigerant line — no tearing open walls or ceilings for ductwork.

Heating & Cooling in One

Ductless heat pumps provide air conditioning in summer and efficient heating in winter, all from one system. Some models work down to -25°C.

Inverter Technology

Unlike traditional systems that cycle on and off, inverter compressors adjust speed continuously. That means lower energy bills and more consistent temperatures.

Zone Control

Each indoor unit has its own thermostat, so you can keep bedrooms cool at night and the living room warm during the day without heating or cooling empty rooms.

Multi-Zone Systems

One outdoor unit can support up to 5 indoor heads in different rooms. Perfect for whole-home comfort without running ductwork.

Rebate Eligible

Ductless heat pumps qualify for rebates through the Canada Greener Homes Grant and Enbridge programs. We help you navigate the paperwork.

Flexible Installation

Indoor units can be wall-mounted, ceiling-recessed, or floor-standing. We recommend the best option based on your room layout and preferences.

Whisper Quiet

Modern mini-splits run as low as 19 dB indoors — quieter than a library. You barely know they are running.

Frequently Asked Questions

A single-zone ductless system (one outdoor unit, one indoor head) typically costs $2,500 to $4,500 installed in the GTA. Multi-zone systems with 2-4 indoor heads range from $5,000 to $12,000+ depending on the number of zones and the brand. We provide free in-home estimates with all costs broken down.
Yes. Modern cold-climate mini-splits from brands like Mitsubishi Hyper-Heat and Fujitsu XLTH are designed to produce heat down to -25°C or lower. They work best as primary heating in well-insulated homes or as supplemental heating alongside a furnace. We help you choose the right model for your climate needs.
We install Mitsubishi Electric, Daikin, Fujitsu, LG, and other top mini-split brands. We recommend Mitsubishi and Daikin most often for their reliability, efficiency, and cold-climate performance. All installations come with manufacturer and labour warranties.
A single-zone installation is typically completed in 4 to 6 hours. Multi-zone systems with 2-3 indoor units usually take one full day. Larger systems may require a second day. We leave the area clean and ready to use when we are done.
Very. Ductless systems avoid the 20-30% energy loss that happens in ductwork. Combined with inverter technology that adjusts compressor speed to match demand, a quality mini-split can cut your heating and cooling costs by 30-50% compared to baseboard heaters or window AC units.
