What Is Ductless HVAC? A Complete Guide for Southern Manitoba Homeowners | Trav's Plumbing & HVAC LTD.
Ductless HVAC — also called a mini-split or ductless heat pump — is a heating and cooling system that doesn’t require traditional ductwork.
It uses an outdoor unit and one or more indoor air handlers connected by a small conduit to deliver temperature-controlled air directly into your living spaces.
This setup offers efficient, quiet, and customizable comfort for homes in Southern Manitoba’s cold winters and humid summers.
If you’ve been considering ways to make your home more comfortable while lowering energy costs, this guide explains exactly how ductless HVAC works, why it’s ideal for our climate, and what you should know before installing one.
Understanding Ductless HVAC Systems
A ductless HVAC system is made up of two main parts:
Outdoor unit – contains the compressor and condenser
Indoor air handlers – mounted on walls, ceilings, or floors to deliver air directly into the room
These are connected by a small conduit that carries refrigerant lines, power cables, and a condensate drain.
Because air doesn’t travel through ducts, there’s no energy loss from leaks or poorly insulated ductwork.
How Does a Ductless HVAC System Work?
Ductless systems use a heat exchange process to move heat between the indoors and outdoors.
Cooling mode – absorbs heat from inside your home and releases it outside
Heating mode – reverses the process, pulling heat from outdoor air — even in freezing temperatures — and moving it indoors
A big advantage is zoning.
One outdoor unit can connect to multiple indoor units, and each zone can be set to a different temperature.
This gives you precise control and can reduce energy use in unused rooms.
Benefits of Ductless HVAC for Southern Manitoba Homes
There are several benefits of ductless HVAC, including:
Energy Efficiency – Avoids duct losses and offers high SEER ratings for lower energy bills
Year-Round Comfort – Works in both hot, humid summers and frigid winters
Flexible Installation – Ideal for older homes, cottages, or renovations without ducts
Zoning Control – Different rooms can be set to different temperatures
Quiet Operation – Indoor units are whisper-quiet, perfect for bedrooms or home offices
Ductless HVAC in Cold Climates: Southern Manitoba Performance
In areas like Morden, Winkler, Altona, and Carman, winters can be brutally cold.
Cold-climate ductless heat pumps are designed for this reality, operating efficiently at temperatures as low as -25°C, and some can still provide heat close to -30°C.
They use advanced refrigerants, variable-speed compressors, and automatic defrost cycles to maintain comfort without overworking.
For extreme cold snaps, ductless systems can be paired with a supplemental heating source.
Ductless HVAC vs. Central Air and Other Systems
How Much Does Ductless HVAC Cost in Southern Manitoba?
For most homeowners in Southern Manitoba, a single-zone ductless HVAC system costs between $4,000 and $8,000 installed.
Multi-zone systems cost more, depending on:
Number of indoor units
Unit capacity (BTUs)
Brand and energy efficiency rating
While the upfront price is higher than portable ACs or electric heaters, ductless systems often pay off in long-term energy savings — especially when replacing older, less efficient systems.
Choosing the Right Ductless HVAC System
When selecting a ductless system:
Match size to your space – BTU capacity should fit the square footage
Select the right number of zones – single for one space, multi-zone for the whole home
Pick the right indoor unit style – wall-mounted, ceiling cassette, or floor-mounted
Check cold-climate performance – choose models rated for -25°C or lower

Frequently Asked Questions
What is the disadvantage of ductless AC?
The main disadvantage is the upfront cost, which can be higher than some traditional systems. Wall-mounted units are also visible in the room, which may not suit every design preference.
How does a ductless HVAC system work?
A ductless system uses an outdoor unit connected to one or more indoor air handlers. Refrigerant lines move heat between indoors and outdoors, providing heating or cooling without ductwork.
What is the average cost of a ductless HVAC system?
In Southern Manitoba, most single-zone ductless systems cost between $4,000 and $8,000 installed. Multi-zone systems cost more depending on size, efficiency, and number of indoor units.
Are ductless HVAC systems worth it?
Yes—especially in homes without existing ductwork or where zoned temperature control is important. They’re energy efficient, quiet, and can reduce utility bills over time.
How long do ductless units last?
With proper care and annual maintenance, most ductless systems last 12-20 years. Longevity depends on the quality of installation and regular upkeep.
Can mold grow in a mini split?
Yes, mold can develop if the system isn’t cleaned regularly, particularly on the indoor coils and in the drip pan. Routine filter cleaning and professional servicing prevent this.
Can ductless HVAC heat my home in winter?
Yes. Cold-climate models work efficiently in temperatures down to -25°C.
Are ductless systems expensive to run?
Ductless systems are usually cheaper to operate than older, less efficient systems.
