I have been using Wojo's Heating & Air Conditioning for forty years and they have always done a terrific job of taking care of my heating and air unit. They recently came out and did a maintenance check on my unit. They were very courteous and professional. When I call to make the appointment for them to come out, I am always treated very well by the person answering the phone. I have recommended them before and I will continue to do so. They are a terrific company.
