Understanding the Ductless Advantage

Ductless Split systems – sometimes referred to as “mini splits” are one of the best ways to keep your home at a comfortable temperature year round.

As the name suggests, the most evident advantage when it comes to ductless split systems is that they do not require ducts (air vents) to be in place before they are installed. We live in a city where many of the houses were built before modern forced-air central cooling and heating systems became ubiquitous. In these circumstances, as well as with many modern homes, a ductless split system is simply the best solution to implement central or localized cooling.

As the previous diagram illustrates, a ductless split system is composed of outdoor and indoor units that are linked by refrigerant lines. The lines are basically hoses that carry fluids instead of cold (or hot) air and as such they are easier to conceal and take up much less space than ductwork.

It is called a ductless split because the indoor units and outdoor units can be quite far from each other. In a very simplified way, you can compare a ductless split system to a window air conditioner unit if you think of the bit of the AC that sticks out of your window onto the outside of your home as equivalent to the outside unit of a ductless split; similarly, the inside unit is like the part of the AC that actually blows the cold air into your room. Clearly, having those two units separate allows for much more flexibility when it comes to designing your living spaces – every room in your home can have a source of cold air even if it does not have an outside wall.

Another benefit of a ductless split system is that they can be much more energy efficient than forced-air systems. The most energy efficient forced-air central A/C we carry achieves up to 22 SEER whereas the most energy efficient ductless split we have achieves up to 26 SEER.

So far we’ve only been talking about cooling your home but ductless split systems can heat your home just as well. This is because the outside unit can be a cooling-only unit or a heat pump. A heat pump is basically an AC that has the ability to work in reverse when it is needed to provide you with hot air inside your house instead of cold. In the late fall and early spring, they can even work with an existing forced-air furnace providing what is referred to as a hybrid-heat system that ultimately results in the highest energy savings. The heat pump will work on its own just fine as well, even in our cold Canadian winters.

A Ductless split system can be arranged as a multi-split and it could be the best solution for balancing the use of available space with available money. A multi-split lets you mix and match several indoor units to fit the layout of the home. Plus, if you ever need to add additional units, they’re easy to install and add to your existing system.
Multi-zone technology allows everyone to enjoy their own preferred level of comfort regardless of where they may be in the home. Due to the fact that each zone operates on its own, someone in the master bedroom, living room or even kitchen can set the temperature to what best suits them.

Whereas all of the above features may not be available to all models of ductless split systems in the market, there is one brand that has all of them and many more features. Due to the flexibility of their systems, their high performance, and reliability; Cozy Comfort Plus recommends Mitsubishi’s Mr. Slim brand of ductless split system.

I requested info online from a few places I found on the internet. Cozy Comfort was the most responsive, not just with the initial info request, but with back-and-forth calls, emails and a site visit. I wanted to convert my wood fireplace to gas, and Brian guided my through the whole process. He explained the type of unit I needed (gas insert), told me the different brands and models that would fit my fireplace opening, and explained the pros and cons of each.

Within a week of my first call, my new gas insert was installed, and a week after that, the stone mantle and hearth were in. The installers laid plastic to protect our flooring, maintained social distance, and were kind to my curious cat and dog. They walked me through how to use the fireplace once the gas insert unit was in. Also, my original fireplace was about 8 inches off-centre (wall is only 13’, so it was noticeable), and Cozy Comfort centred the new one - it looks stunning.

Thanks for everything, Cozy Comfort! I can’t wait for winter 😄

Cozy Comfort Plus Inc. installed a new high efficiency furnace in our house two years ago and it has been operating perfectly ever since. Their service was straight forward, reasonably priced and good value for money. They even walked us through the complicated rebate program that was hard to understand without being involved in the industry.

I would highly recommend them for your next heating and cooling needs.

I can't stress enough how happy & pleased we are with our Napoleon BBQ. From the moment we walked into the showroom, we were met with a very friendly greeting.

My wife and I were so impressed with the calm, sincere and gracious demeanor of Brian. He answered all our questions, gave us his thoughts and professional opinions on everything inquired about.

We will definitely continue our business with Brian and the entire team at Cozy Comfort Plus.
