Ductless Mini-Split Heat Pumps

Ductless Mini-Split Heat Pump Installation

Ductless mini-split heat pumps are one of the most flexible and energy-efficient ways to heat and cool specific areas of your Oshawa home. With no ductwork required, mini-splits are ideal for home additions, older homes without existing ducts, garages, home offices, and rooms that your central system struggles to keep comfortable. Modern Home Energy installs single-zone and multi-zone ductless systems across Oshawa and all of Durham Region.

What Is a Ductless Mini-Split and Is It Right for Your Home?

A ductless mini-split consists of a small outdoor compressor unit connected to one or more indoor air-handling units by a refrigerant line through a small hole in the wall. Unlike central systems, mini-splits deliver heating and cooling directly to the room where the indoor unit is mounted — with no ducts, no heat loss, and no need for major renovation work. Installation is typically completed in one day.

Single-Zone vs Multi-Zone Mini-Split Systems

Single-Zone Systems

A single outdoor unit connected to one indoor air handler. Ideal for conditioning one specific room or space — typically a large master bedroom, finished basement, home office, or addition. Single-zone systems are the most affordable entry point and are typically installed in one day.

Multi-Zone Systems

One outdoor unit connected to two, three, or four indoor air handlers in different rooms. Each indoor unit operates independently, allowing different temperatures in different zones. Multi-zone systems are ideal for older homes needing whole-home coverage without ductwork, or for any home where room-by-room temperature control is a priority.

Up to 4 indoor zones from a single outdoor unit
Each zone controlled independently by its own remote or smart app
Efficient all-electric heating and cooling with inverter-driven compressor technology
ENERGY STAR® certified models available for Ontario rebate eligibility
Wall-mounted, floor-mounted, and ceiling cassette indoor unit styles available
Whisper-quiet operation — typically 19–26 dB for indoor units

Ductless Mini-Split FAQ

Can a mini-split heat a room in an Ontario winter?

Yes. Modern cold-climate mini-splits operate efficiently down to -25°C to -30°C and are designed for Canadian winters. Many Oshawa homeowners use mini-splits as their primary heating source in additions and spaces where gas heat is not practical.

How much does a ductless mini-split cost in Oshawa?

Single-zone systems & Multi-zone systems cost increase with the number of indoor units. Contact us for a free quote specific to your home.

Do I need ductwork for a mini-split?

No — that is the key advantage of a mini-split. The only penetration required is a 3-inch hole through the wall for the refrigerant line, power cable, and condensate drain. No ductwork, no major renovation.

Is a mini-split better than a window AC?

Yes in most cases. Mini-splits are more efficient, quieter, heat and cool in one unit, don’t block a window, and have a much longer lifespan (15–20 years vs 5–10 years for a window AC). The higher upfront cost is typically recovered within 3–5 years.
