Cozy World fully deserve their high Homestars rating. Everything I read about them beforehand on this website, proved true: their quote was highly competitive (in my case even the cheapest) and all-inclusive (no surprises), (owner) Boris' pre-sales communication was excellent (fast and to-the-point, no questions unanswered), the install crew (Fred and colleague) was punctual, fast (six hours start to finish), skilled, helpful and they respected my property. Suffice to say, the reviews are true.
I could leave it at that, but there are a few things that deserve extra mention. First of all, the main competing quote also came from a Homestars top-ten company. Obviously, anyone topping those charts has an excellent track record. But unlike the competition, Cozy World accurately sized my equipment, while the other guys tried to push models too big for my (small 1,100 sq ft) house (and if there's one thing I've learnt, it's not to oversize furnace or AC). Second, Cozy World are the only ones to post prices on their website. That may not seem like a big deal, but I very much appreciate the transparency, and the confidence it implies (and once competing quotes start rolling in, you'll know why Cozy World can be that confident, unlike everyone else). Also, Boris is the least typical salesman I've ever had to deal with, and that's a big compliment. Like everyone else I reserve a healthy dose of scepticism for salesmen of any ilk. Boris, I trust. His answers to my (several) questions were so devoid of bloat or up-selling, he almost seemed aloof initially (which he isn't, to be clear). His candour is unparallelled. He'd consistently go for the cheapest option available that would suit my needs. Also, he made a point of fully explaining why they'd have to install a chimney liner (code requirements, which I was already aware of, so I knew he wasn't BS-ing me).
I know I'm waxing lyrical in this review, but all for good reason. If a company can turn a potentially arduous and stressful experience into a pleasant one, they deserve a wholehearted recommendation.
