How does a mini split system work? Does it plumb into traditional ducting?

Edit: just looked them up. Also found out that a friend out East with an older, oil heater house (no central ducting) was quoted a mini split for their place at over $20K

Our place is a four bedroom, two storey with a basement. I wonder if a mini split with the requisite air handlers would be cheaper

On a side note, we have a West facing room with large windows that I have to run a portable AC and space heater in as it's temp is always extreme vs the rest of the house. A mini split just for that room would be great

They are honestly pretty easy to install if you are at all handy. The smaller ones (like for a room) have minimal electrical needs and are something you could get an electrician buddy to do for a case of beer if you buy the parts off amazon. Depending on the brand they are varying levels of DIY but nothing a 5 min youtube video can't teach you. All in for my house it was 6k and a saturday afternoon to get it done.

How many mini split heat pumps and air exchangers did you put into your place

Overall, we should be net $5K with an installer because of rebates, but it's good to know cheaper alternatives are available

My quote from the installers that were on the list of qualified installers for the rebate was always around 20K and up for a 3 head system. It was not worth paying the premium to get the rebate but I'm pretty handy on the tools.

I could break my system completely 2 times and still come out spending less when I bought a 3rd one compared to having a "Qualified Pro" install it for me. Especially since I now have all the hole saws, vacuum pump, flare kit, electrical is done etc, so there is no added expense beyond buying the unit now.

If you are not comfortable with gas fittings, electrical, cutting holes in the side of your house etc... It might be a different calculation.

The one I bought is under 4k CAD. https://senville.ca/36000-btu-tri-zone-mini-split-air-conditioner-sena-36hf-t/ and is medium DIY friendly.
You can get brands like Mr.Cool that are very simple to install.
