When I wanted to change my central air conditioning 2 years ago I contacted Boris and 3 other companies. Boris gave me 100% accurate advice and steered me in exactly the right direction. He stuck 100% to the quoted price and actually did a little more than he was contracted to do. His installation was perfect, they explained the operation of new unit well, and Boris filled out and followed up on the $500 rebate I was to receive. His pricing was also excellent. When I phoned him yesterday to recommend a friends upcoming job to him he could still remember most of the details of my installation and home configuration from the top of his head. If I could award it he would get an 11 out of 10. On my recommendation he also did my friend's A/C and furnace and also did a perfect job there. When I need a new furnace I will only make one call - to Boris! You can't go wrong with Boris and Cozy World.
