Nowak's Heating & Air Conditioning Inc Reviews
5 out of 5 stars, based on 1 review

  • By Paul N.
    October 22, 2014

    Buying a new central heat system is not something you do every year, so I was a little nervous learning what I needed to know before I got mine installed. I interviewed 3 companies and selected Nowak Heating & A/C because Paul was the most knowledgeable and easiest to understand when explaining all the options available. My new system works flawlessly, and the installation was completed sooner than I expected. If you are looking for a new heating system, do yourself a favor and call Paul Nowak. Don't make a mistake and hire a company with less experience. It sure made a difference for me!
