My 90 year old mother called to say that her furnace was not working, I called Bob Nowak and told him of the situation. This was on Super Bowl Sunday and he came to the house within an hour, he did several tests, and looked the whole furnace over. After diagnosing the problem, he found carbon monozide in the house and recommended that we remove my mother from the house. A new furnace was installed within four days. We highly recommend R.A. Nowak Heating and Cooling for anyone in need of his excellent service.
