I am an elite Yelper. I know good. I know bad. The owner is a genuine businessman and knows the true meaning of customer service His staff, esp Lukasz is amazing and respectful and knowledgeable (I had little ones running around) They installed central air in our old bungalow (we had old school window AC units) I wish I could rate him 10 stars.

We had Cool Z heating service both our boilers on our two flat last year and had him replace one boiler from 1987 this year! He is honest, kind, curteous, and is everything you would want in a HVAC company. Out of the four people we called, he was the second lowest and price matched the lowest quote. As a new hone owner I was out of my element when it came to heating maintenance and he was always available to answer my questions with knowledge and patience.
He respected that this was an enormous purchase for us and I am glad we were recommended him by a friend in the community. I highly recommend him to anyone needing to get their furnace or boiler maintained for the yearly maintenance of cleaning and servicing and should you have to replace a boiler, give him a call and get a quote. I don't think you will be sorry. Maciej, if you read this, thank you again for your hard work today and I am happy to give you a rave review!

I have a wall space heater, and they said they worked on them so I scheduled an appointment. First, no one showed up at the specified time. I called back, and whoever answered the phone agreed to swing out and take my furnace cleaning appointment. He looked at my furnace and told me I needed a new control "because plastic had melted around the control". I asked for a price, and a follow up to replace it. Never heard back. We went down later to "remove the plastic", and we did not see any material "melted" around the control at all. I would find it hard to trust this business.

This guy and his workers are the best. I used them for several different projects. They replaced an AC unit on my roof. When we had some issues with drainage, he was there within half a day of when i called. He stood by his work and fixed any problems that came up. even if we couldn't prove it was directly related to his work. I gave him keys to my place and he would come and go as he needed to (even when we weren't home). They are very trustworthy and honest/upfront with prices. I highly recommend.
