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.

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.

We are so happy with the service, support and product that we received from Cozy Comfort Plus. Brian was incredible to work with, he took the time to understand what we were looking for and helped us with the designs and what the best fireplace for us might be. He is extremely easy to work with, very easy to communicate with and so fast and responsive!

Everything happened exactly on schedule and as planned. It was a well oiled machine!! The crews that were here to build everything were super friendly, kind, courteous and knowledgeable.

Highly highly recommend to all 😀👍
