Ductless heating and cooling systems are ideal for houses or additions without ductwork, as well as other circumstances where a traditional central air conditioner or forced-air furnace would be ineffective.
What Is Ductless Heating and Cooling?

Ductless cooling and heating systems operate without the need of ductwork, as the name implies. There are two distinct elements in these systems: an outside compressor and an inside evaporator. The indoor unit is in charge of bringing cold, regulated air into the living area, while the outside unit is in charge of releasing the absorbed heat outdoors. These two compartments are linked by a tiny hole in the wall.
The Pros of A Ductless Heating and Cooling System
- Lower Ductless Cooling & Heating System Operating Costs
For most of us, this is a great and important aspect when purchasing a system for the home. We all appreciate gadgets that help us save money on our monthly energy costs. It's also critical for the environment that we reduce our carbon impact. When compared to ducted air conditioners, ductless air conditioners are significantly less expensive to run. - Ductless Air Conditioners Are More Efficient.
Furthermore, ductless heating and cooling systems are quite efficient in terms of energy. It is known that a ductless system saves you 25 percent more energy than a system with ductwork. - A Ductless Hvac Installation Is Simple and Easy
Due to the lack of ducts, ductless air conditioners may be installed in a fraction of the time that ducted air conditioners can. Furthermore, installation work is minimal, therefore, installation expenses are kept to a minimum. - Easy to Install
In comparison to window units, ductless units only require a tiny hole in the wall to be drilled, making them less prone to air leakage and security issues. They're also less apparent and noisy. For more information please check our ductless heating and cooling blog.
The Cons of A Ductless Heating and Cooling System
- Ductless systems are several times more expensive than equivalent window or baseboard heating units for a single room solution. Furthermore, replacing your old central heating and cooling system with a complete ductless solution might cost two to three times as much as merely replacing it with another duct unit. You'll save money on your energy bills, but the payback period is determinant on your climate, how often you use the system, and your local power costs.
- To keep your system running well, you'll need to clean the filters in each unit once a month (more often if you are a smoker or own pets). It is something you should not skip on: ductless fans can't tolerate collecting dirt, and if you put off maintenance until it's too late and professional cleaning is necessary, you'll wind up spending lots of money and perhaps shortening the life of your system.
- Many homeowners are afraid to install ductless heating and cooling systems because they are not always attractive. They are available in conventional white or beige and are not coverable.
What's the Ideal Situation for Ductless?
- Garage spaces, extra rooms, and sunrooms and all new additions. The major advantage of ductless in this situation is that it will be correctly suited for the additional area and will not steal air from other rooms or overwork your existing HVAC system.
- Assisting a room with particular heating and cooling issues.
- Installing air conditioning in a home that lacks ducting. Although ductless air conditioning is expensive, it is less expensive than installing ducting to an existing home.
- Ductless heating and cooling systems are great for generating separate temperature zones in various rooms.
Ductless Heating and Cooling vs Central System
A ductless air conditioning system is similar to a central air conditioning system. They're both made up of two parts: an outside condenser and an indoor evaporator/air handler. The heat is carried from the indoor unit to the outdoor unit, where it is discharged, by coolant passing between the two units. With a central air system, however, the cold air is sent via your furnace's air handling unit and into the ductwork, where it is distributed throughout the home. A ductless system employs a thin wire to connect the condenser to a wall box, eliminating the need for ducting and floor vents.


Call us today for all of your HVAC needs, including ductless installation, emergency heating and cooling system repairs, and maintenance. We'll be there for you every step of the way, from selecting the correct model to correctly installing your system and providing continuous maintenance and support. We are also hosting a current multi-zone ductless heat pump promotion that is one system for both heating & air conditioning. Heats the house to -30c ambient and is more efficient than a central system.
Ductless Air Conditioner
A ductless air conditioner system differs from central air conditioning by blowing cold air directly into one living space rather than delivering cool air to the entire home through a series of ducts and vents. A complete ductless system includes an indoor unit with a blower fan and an evaporator coil, and an outdoor unit with a condenser coil, compressor, and fan. The two units are connected with electrical wiring and copper refrigerant tubing. A few more distinguishable characteristics of different types of ductless AC units are:
- High wall units are directly mounted to an interior wall
- If wall mounting is’t possible or desirable, console units are the preferred choice here
- In-ceiling units are hidden from sight if the ceiling space allows such secrecy
- Cassette units can be directly mounted to the surface of the ceiling
In order to minimize noise heard in living spaces, from outdoor gathering spots, or from patios, outdoor units are strategically placed.


A ductless air conditioner is a beneficial addition to any home environment. As with any appliance however, there are many factors to consider before making the purchase This is everything you need to know about ductless ACs:
- Cost: A single-zone system with one indoor unit will cost significantly less than installing a four-zone system. Consult with a licensed tech for more info.
- Installation: You'll need a professional to mount the indoor and outdoor units, to connect the refrigerant lines and wire the electric cables.
- Maintenance: We recommend removing and cleaning the filter on each indoor unit every month. Once a year, have a Therm Energy technician check refrigerant pressure and flush condensate lines.
- Noise: Indoor units have whisper-quiet fans driven by long-life DC motors, designed to keep noise at a minimum.
- Warranties: Coverage ranges depending on the manufacturer, but you can expect this sort of mechanical equipment to last 15 to 20 years before it needs to be replaced.
Ductless Air Conditioning Installation In Toronto
When Toronto homeowners want to install a ductless air conditioning system in their residence, the size is always in question. Do I have enough space? How much room do I need to allocate?
How do I know what size will circulate the air the best? We're here to tell you, deciding on the best size unit is easy once you know what to consider. Simply calculate a room’s square feet and include additional areas such as closets for example.
Then, consult a sizing chart to determine the number of BTUs required for that space to be cooled appropriately. Here is an abbreviated list of BTU capacity:
- If the space to be cooled is between 150 to 250 square feet, the capacity in BTUs per hour is 6,000.
- If the space to be cooled is between 250 to 300 square feet, the capacity in BTUs per hour is 7,000..
- If the space to be cooled is between 300 to 350 square feet, the capacity in BTUs per hour is 8,000..
All mini-split systems are capable of outputting a specific number of BTUs. This number is influenced by square footage, capacity, and your home’s insulation situation as well.
Naturally, a poorly insulated building will require a larger system because it is riddled with air leaks. The main importance is to ensure insulation is up to par before proceeding.

Ductless HVAC

A ductless HVAC system, also known as a mini split, is a heating and cooling system that delivers warm or cool air to a single room or several without the need for connective ductwork. Mini split systems are a great option for room additions, garages, sunrooms, or areas of the home that need to be warmer or cooler. Ductless HVAC systems are advantageous over traditional ducted systems for the following reasons:
- Zoning: Ductless HVAC systems can be controlled separately. This means you can meet your specific comfort and efficiency needs depending on the room by setting the indoor air temperature accordingly.
- Inverter Technology: A ductless system offers both heating and cooling capabilities all in one unit. You’re able to achieve desirable temperatures at a faster rate and with minimal temperature fluctuations.
- Extra Quiet: Ductless HVAC systems operate with significantly less noise because the major parts of the unit are placed outside your home. Also, air comes out of the side of the outdoor unit, rather than the top.
- No Ductwork Necessary: When you opt for a ductless HVAC system, you save time and money because you do not need any ductwork under or through the house to cool your home. The installation process is quicker and less disruptive because there is no ducting involved.
- Flexible Placement: A ductless HVAC system offers a lot more placement options and strategic flexibility to get the highest efficiency and optimize comfort.
It’s no secret why ductless HVAC systems are becoming increasingly popular across households all over the GTA. Call a Therm Energy tech today to start reaping the benefits of this heating and cooling unit.
