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!

Highly recommended. Brian at Cozy Comfort Plus supplied and installed 6 ductless heads on two compressors. The price was very competitive. The installation crew lead by Hamid did a perfect job. They explained the best locations for the equipment and answered all my questions. The work was completed a very short time after signing the contract. The team cleaned up the job site very carefully every night and were very careful indoorA.
