Ductless Heating
Cold-climate heat pumps for Ottawa homes, additions and rooms without ductwork.
Ductless heating in Ottawa
A warmer home, without adding ductwork
If your home has electric baseboards, radiators or rooms that never feel warm enough, a ductless heat pump could make a welcome difference.
We install cold-climate systems that deliver heat directly to your living spaces. They can serve one room or several areas of the home, with air conditioning from the same equipment in summer.
AirZone starts with how you use each room, the heating already in place and the comfort you want to improve. Our team plans the equipment and locations, explains any remaining heating needs and helps you make the most of eligible rebates.

How ductless fits with your existing heating
Reducing your reliance on electric baseboards
A heat pump moves heat into the home instead of generating it with an electric element. It can use less electricity to warm the areas it serves. We look at your heating use and room layout to decide where it will do the most work. Baseboards may still be useful in closed rooms or as backup.
Adding comfort to a home with a boiler
You can add ductless heating and cooling without connecting it to the radiator piping. The new system conditions the rooms it reaches, while your existing boiler may continue serving other spaces. Before planning a larger conversion, we also check whether the boiler supplies your domestic hot water and what heating will remain.
Warming an addition, office or family room
A room used every day deserves dependable heat. A single-zone system can be useful where the existing heating falls short or extending ducts is impractical. We check insulation, windows and heat loss first, so the equipment is chosen for the space’s winter needs as well as summer cooling.
Plan the heat room by room
One room, several rooms or the whole house?
The number of indoor units depends on where heat needs to go. An open living area is a different job from a floor of bedrooms with the doors closed.
We compare single-zone and multi-zone arrangements using the needs of each space. One outdoor unit is convenient, but separate systems can also be worth considering where rooms have very different heating demands or are far apart.
Common ductless heating layouts
| Layout | Where it can fit | What we review |
|---|---|---|
| Single-zone system | One room or a connected open area, using one indoor and one outdoor unit. | Airflow across the space, heating demand and how the unit performs when only a little heat is needed. |
| Multi-zone system | Several indoor units connected to a compatible outdoor unit. | Each room’s load, total winter capacity, approved indoor combinations and controls. |
| Separate single-zone systems | Areas that benefit from separate equipment, subject to space and installation requirements. | Outdoor locations, electrical needs, piping routes, performance and the total installed cost. |
Have ductwork, but still have cold rooms?
AirZone ComfortSpan combines a compatible central connection with up to four additional ductless zones on one outdoor heat pump. It can serve rooms that need direct heat while keeping central airflow matched to your ducts. Where the home and approved equipment support more eligible heating capacity, the design may also improve the available rebate. We’ll help you compare it with a separate ductless system.
Cold-climate ductless heat pumps for Ottawa winters
A mini split’s ability to cool a room doesn’t tell you how much heat it can deliver during an Ottawa cold snap. For a system doing substantial winter heating, we review its cold-weather output and efficiency in the proposed indoor and outdoor combination.
Available heat has to match the demand
We compare the room’s heat loss with the equipment’s output as the outdoor temperature falls. On a multi-zone system, that includes how much capacity is available to the connected rooms when they need heat together. The lowest operating temperature in a brochure is only part of that decision.
Plan for backup and normal defrost cycles
The design should identify whether existing heaters need to remain and when you’ll use them. Outdoor units also defrost periodically in winter. Your walkthrough covers normal operation, keeping airflow clear and when persistent ice or poor heating needs a service visit.

Where will the indoor and outdoor units go?
Equipment placement affects comfort, appearance and how easily the system can be maintained. We discuss these details before the installation is scheduled.
- Indoor airflow and furnitureWe look for a location that can distribute warm air into the occupied space without aiming directly at a bed or favourite chair. High-wall units are common; compatible low-wall or ceiling options may suit some rooms.
- Cleaning and accessYou need room to reach filters, and the technician needs access for service. The mounting location also has to meet the selected unit’s clearances.
- Piping and summer drainageThe indoor and outdoor units connect through refrigerant lines, wiring and a wall opening. Cooling produces condensate, so we plan its drainage and discuss any pump or visible covers the installation needs.
- The outdoor locationSnow, defrost water, airflow, sound, nearby windows and service access all influence placement. We also confirm the equipment’s electrical requirements.
What does ductless heating cost in Ottawa?
What your installation quote covers
The largest difference is usually the amount of the home you want to heat. A unit for an open family room involves different equipment and work from a system serving several bedrooms on separate floors.
Your quote should identify the indoor and outdoor models, the spaces they will serve and the work included. Installation costs can change with electrical requirements, the length and route of refrigerant lines, access, drainage and the type of indoor units.
We’ll also explain the difference between a system providing supplemental heat and one expected to carry most of the winter load. That distinction affects equipment selection and the heating you may need to keep.
If spreading the cost would help, ask about financing options, subject to approval and financing terms. We compare the installation price and anticipated rebates clearly.
Ductless experience in Ottawa homes
We’ve been helping Ottawa homeowners with heating and cooling since 2005. Our own technicians install and service the equipment, and our team’s work includes researching, designing and installing ductless systems for local homes.
We know why these systems appeal to owners of homes in the Glebe, Westboro and Centretown: many have established radiator or baseboard heating and limited space for ducts. The same approach can help with an addition or a difficult room in a newer home.
Our ductless selection includes Lennox, Mitsubishi Electric and Moovair, with the model chosen for the job. Compare our equipment brands and dealer credentials and the systems below.
We serve Ottawa, Kanata, Nepean, Barrhaven, Orleans, Stittsville and surrounding communities. Check our service areas or call with your postal code.

Ductless heating questions
Can ductless heating replace all my electric baseboards?
It may be able to take over much of the heating, but the answer depends on winter capacity and room coverage. Before removing baseboards, we assess each space, including bedrooms with closed doors, bathrooms and areas without an indoor unit. Some heaters may remain for backup or to serve rooms outside the new system’s coverage.
Will one indoor unit heat bedrooms down the hallway?
Not reliably in every layout. Warm air needs a clear path into each room, and closed doors limit that movement. We consider the way you actually use the bedrooms when recommending indoor-unit locations. A separate zone or another heating source may be needed to keep those rooms comfortable.
Can I keep my boiler and add ductless heat?
Yes, in many homes the two systems can be used alongside each other. Ductless equipment delivers warm air directly to its zones, while the boiler serves its radiators or other connected loads. We review any hot-water function and the rebate requirements before recommending changes to the existing heating system.
How many indoor units will I need?
The number depends on room heat loss, floor plan, airflow and which spaces you want the system to heat. Floor area alone is not enough to choose the layout. We also check that the outdoor unit can support the proposed indoor combination when several rooms need heat at the same time.
Can each room have its own temperature setting?
Compatible multi-zone systems let you set temperatures for individual indoor units. The equipment still shares an outdoor unit and its available capacity. We explain how the selected controls coordinate the rooms, which settings you can adjust separately and any operating limits before you choose the system.
Do ductless heat pumps qualify for rebates in Ontario?
Eligible cold-climate ductless systems may qualify under current programs. Your existing heating fuel, the approved equipment combination, eligible heating capacity and application timing all matter. AirZone’s team has completed in-house rebate training and helps with the equipment review and required submissions. Approval must be in place before eligible Home Renovation Savings installation work begins.
Does ductless heating also provide air conditioning?
A ductless heat pump can reverse operation to cool the spaces it serves in summer. It also removes moisture while cooling. If summer comfort is the main reason for the project, our mini-split air-conditioning page explains the cooling options. We consider both seasons when selecting your equipment.
What will the indoor unit look and sound like?
High-wall units are common, while compatible low-wall units or ceiling cassettes may suit some homes. Dimensions, fan sound and control options vary by model and operating setting. We review the proposed unit, its clearances and placement, including whether a condensate pump is needed, so you know what to expect.
Will you install a ductless system I bought online?
We generally supply and install the systems we recommend. If you have already purchased equipment, contact us with the model information before arranging installation. We’ll confirm whether we can help and review compatibility, warranty requirements and parts support for that equipment.
