From installation to maintenance, Cozy Comfort Plus Inc. provided us with prompt, quality service. It took under a day to install our Mitsubishi split-type air conditioner in May, 2021. This week, they attended to cleaning our unit’s filters in less than a day’s notice. The technician explained how to remove, clean and reinstall the filters ourselves which will save us money down the road. I highly recommend Cozy Comfort without reservation.

I had the most fabulous experience with Cozy Comfort Plus! Brian was very responsive for my first outreach all the way through to the completion of my beautiful fireplace! I live in a condo and as such, things are not straightforward when it comes to having work completed. There were a few extra hoops to jump through but Brian and his team were very diligent in ensuring that all the fittings were correct. I was so happy with my experience that I had them replace my furnace and add a smart home thermometer as well! I would highly recommend Brian and his team for their knowledge, skill and excellent customer service!

Brian once again helped me with my project. Before I have installed a gas fireplace and this time I have installed an LG heat pump with 3 indoor heads. We had an amazing experience with Brian and his team for both projects from quote to installation. Brian is experienced, patient, reliable, and provides great friendly service. He’s also tells very interesting life stories which makes enhances the whole experience. All my future business is going to his company. Thanks again Brian!
