I found out about Nowak Heating & Air Conditioning through a referral. They were polite and patient when I asked my laymen questions. They were prompt in turning up for the service. They installed a heating and air conditioning unit in our house. On the first visit they were able to resolve any issues I ha. They were professional and treated me as a customer with respect. I like their total customer service approach, which means the customer is first. I've been using Nowak Heating & Air Conditioning for five years so they've done initial services as well as follow-ups. They provide exceptional customer service worth taking the time and spending the money for!
