Ductless Mini-Split Installation in Toronto
A ductless mini-split heat pump heats and cools your home without ductwork, giving you year-round comfort with one of the most energy-efficient systems on the market. Imperial Heating installs Mitsubishi, Daikin, LG, and Fujitsu mini-splits across Toronto and the GTA with expert sizing, clean installation, and full warranty support.
What Is a Ductless Mini-Split and How Does It Work?
A ductless mini-split is a type of heat pump that provides both heating and cooling through a compact, wall-mounted indoor unit connected to an outdoor compressor. Unlike central air systems that push conditioned air through a network of ducts, a mini-split delivers it directly into the room. This eliminates the energy losses associated with ductwork, which can account for up to 30% of a central system's energy consumption.
The system works by transferring heat rather than generating it. In summer, the indoor unit absorbs heat from the room and sends it outside through refrigerant lines, cooling your space. In winter, the process reverses: the outdoor unit extracts heat from the outside air (even at sub-zero temperatures) and moves it indoors. Modern cold climate models from brands like Mitsubishi Hyper-Heating and Daikin operate effectively down to -25C, making them fully viable for Toronto's winters.
Each indoor unit operates independently, so you can set different temperatures in different rooms. This zone-based approach means you are only conditioning the spaces you actually use, rather than heating or cooling the entire house to a single temperature.

Ideal Applications for Ductless Mini-Splits
Mini-splits are versatile systems that solve heating and cooling challenges where traditional ductwork is impractical or inefficient.
Homes Without Ductwork
Older Toronto homes, row houses, and century homes that were never built with duct systems are ideal candidates. A ductless mini-split delivers heating and cooling without the cost and disruption of installing new ductwork throughout the house.
Condos and Apartments
Many Toronto condos rely on outdated PTAC units or inadequate building HVAC. A wall-mounted mini-split provides efficient, quiet climate control with individual temperature settings for each room. No ductwork modifications required.
Home Additions and Renovations
Adding a new room, finishing a basement, or converting an attic? Extending your existing ductwork is often impractical and expensive. A single-zone mini-split heats and cools the new space independently without affecting the rest of the house.
Supplemental Heating and Cooling
Hot or cold spots that your central system cannot reach, like a sunroom, above-garage bonus room, or home office, benefit from a dedicated mini-split zone. It fills the gap without overworking your primary HVAC system.
Garages and Workshops
A mini-split turns an unheated garage or workshop into a year-round usable space. Cold climate models from Mitsubishi and Daikin operate efficiently even at -25C, making them practical for Toronto winters.
Energy-Conscious Homeowners
Mini-splits are among the most efficient HVAC systems available. With SEER ratings up to 33 and HSPF ratings above 13, they use significantly less energy than conventional systems, lowering your monthly utility bills year-round.
Single-Zone vs. Multi-Zone Mini-Split Systems
Choosing between a single-zone and multi-zone configuration depends on how many rooms you need to condition and your budget. Both options use the same core technology, but the setup differs.
Single-Zone
- One outdoor unit connected to one indoor unit
- Ideal for a single room, addition, or garage
- Lower upfront cost ($3,000 to $5,000 installed)
- Simplest installation, often completed in a single day
Multi-Zone
- One outdoor unit connected to 2 to 5 indoor units
- Each room has independent temperature control
- Whole-home solution without ductwork
- Higher upfront cost but lower per-zone cost than individual units
Our technicians assess your home's layout, insulation levels, and heating and cooling load to recommend the right configuration. We size every system using Manual J calculations to ensure proper capacity, not just rule-of-thumb estimates.
Mini-Split Brands We Install
We install and service the top ductless mini-split brands available in Canada. Each brand has its strengths, and we help you choose based on your priorities: whether that is maximum cold-weather performance, the quietest operation, or the best value for your budget.

Efficiency Ratings: SEER and HSPF Explained
When comparing mini-split systems, two numbers matter most: SEER for cooling efficiency and HSPF for heating efficiency. Higher numbers mean lower operating costs.
SEER (Cooling)
Seasonal Energy Efficiency Ratio measures cooling output divided by energy consumed over a season. The minimum for new equipment in Canada is 14 SEER. Top mini-splits reach 33 SEER.
For context: A typical central AC is 14 to 18 SEER. A high-end mini-split at 25+ SEER uses roughly 40% less electricity for the same cooling output.
HSPF (Heating)
Heating Seasonal Performance Factor measures heating efficiency. The minimum is 8.2 HSPF. Cold climate mini-splits from Mitsubishi and Daikin achieve 13+ HSPF, meaning they produce over 3 units of heat for every unit of electricity consumed.
For context: An electric baseboard heater has an effective HSPF of 3.4. A 13 HSPF mini-split is nearly 4 times more efficient for heating.
These efficiency gains translate directly into lower utility bills. Many homeowners who switch from electric baseboard or older gas furnaces to a ductless mini-split see heating cost reductions of 30% to 50%, depending on their previous system and insulation levels.
Advantages Over Central HVAC Systems
While central heating and cooling systems work well for many homes, ductless mini-splits offer distinct advantages in certain situations:
No ductwork required
Saves $5,000 to $15,000 in duct installation costs and avoids the construction disruption of running ducts through walls, floors, and ceilings.
Zone-by-zone temperature control
Set different temperatures in each room. Stop heating or cooling empty rooms. A central system conditions the entire house to one setpoint.
Higher energy efficiency
No duct losses, inverter-driven compressors that modulate output, and SEER ratings nearly double those of conventional central air systems.
Quieter operation
Indoor units operate at 19 to 30 dB, quieter than a whisper. No rumbling ductwork or noisy air handlers. The outdoor unit is also significantly quieter than a central AC condenser.
Both heating and cooling in one unit
Replace two systems (furnace + AC) with a single mini-split. Cold climate models handle Toronto winters without a backup heat source.
Quick, minimally invasive installation
Only a 3-inch hole through the wall connects the indoor and outdoor units. Most single-zone installations are completed in 4 to 6 hours.
Our Mini-Split Installation Process
Every installation follows a structured process to ensure proper sizing, placement, and performance. We do not cut corners.
In-Home Assessment
We visit your home to assess the space, measure room dimensions, evaluate insulation, check electrical capacity, and determine the optimal indoor and outdoor unit placement. We perform Manual J load calculations to size the system correctly.
System Selection and Quote
Based on the assessment, we recommend the right brand, model, and configuration. You receive a detailed written quote covering equipment, installation, electrical work, and applicable rebate amounts. No surprises.
Professional Installation
Our licensed technicians mount the indoor unit, place and secure the outdoor unit, drill and seal the refrigerant line passage, run the copper lines and drain, connect electrical, and vacuum and charge the system. We use proper line covers and ensure a clean, finished look.
Testing and Walkthrough
We run the system through heating and cooling modes, verify refrigerant pressures, check airflow, and confirm the thermostat and remote control operation. Before we leave, we walk you through the controls and answer any questions.
