My father, nearly senior, a construction professional, and living on my street needed a new furance. I needed an air conditioner. We decided for ease to try and find a company that could do both, in a day, in our respective houses. We were simply looking for a straightforward installer, who could provide a clear detailed quote, and install on a convenient schedule. Boris met all of these requirements and made this installation very straightforward, transparent, and punctual. The crew did a clean job and Boris provided excellent pre and post-sales communication. I havent had much chance to try my air conditoner yet as it is still April, my father's furnace is very good and I give Boris credit for recommending this unit. Thank you Cozy World for being an honest and easy to work with company.
