You can tell this is a family owned business by how thorough they are. Chris Nowak was assigned to my job and he figured out my heating problem in 5 minutes. He also looked at the direct venting system on the furnace and explained how it works. He even measured the length of the vent PVC pipe and made sure that it fell into the specs for the BTU’s my furnace puts out. Very impressive and I understand why they are so highly rated.

We have asked Nowak to come and service our boiler for years, both for regular maintenance and repairs needed. Chris and Alex have both worked at our house and every time, without fail, they are courteous, communicative, clean and do amazing work. I would not hesitate to recommend them to anyone.

Sarah B.

I can not say enough about Chris and his team. He was beyond knowledgeable regarding the issues with our furnace and went over all of our options to remedy and replace. We ended up going with a full furnace and AC replacement and his crew did an amazing job. They were extremely neat, clean and communicative during the entire install. As a new homeowner it was important to work with someone I trusted and I beyond trust Chris and his crew. I would confidently recommend them to anyone!
