  I have installed a 3 ton universal unit and has been working great! I installed & started it up in January during a very cold time. i was very impressed with heat output at temperatures between -15c and -25c for about 2 weeks! Tyler was a great help with the sale and with the few questions I had during installation! I am impressed with the quality and would recommend this to anyone!

  Great value and DIY friendly service.  My install replacing an existing central AC unit with a MR Cool Universal heat pump went very smoothly - (one word of caution - the pre-charged line set is very stiff and hard to handle - and each line has about 1 inch of added insulation - so it won't fit in a standard line set cover system).  The system was delivered quickly and well packaged.  Operation is whisper quiet, which I'm sure is a relief for my neighbours...  I previously installed a Mr Cool mini-split in Florida, and that was even simpler.  I highly recommend.

  Tyler and the team at Mr Cool Canada gave us amazing support when we needed it. It's nice to see a product being backed up by the manufacturer in this day and age. Excellent products and service- should be six stars available!

  Very happy with the product. Delivery was quick and I needed some support when the unit displayed an error code when first starting it up.  Customer support was quick and very helpful.  Highly recommend.
