Mr. Cool vs Senville

Hello everyone,

I'm located in southern ontario and I want to try DIY heat pumps this year. I have a Gas furnace as backup but it doesn't work super well as we have an old stone farm house and it's difficult to get vents everywhere.

I've done tones of renos before but never anything HVAC. I'm looking for 2 x 18k dual zone units and 1 x 28k tri-zone unit. Going to have an electrician wire all the conduits but I was wondering if it would make a bit difference for installation to go to Mr. Cool vs Senville. Mr. Cool total cost of equipment is roughly $16K CAD and the Senville will be roughly $9k CAD.

Any advice is appreciated.

Thank you kindly!
