Established in 1990.

We are a small family business. My name is AJ. I graduated from Ivy tech with a degree in heating, cooling and refrigeration. I have either worked for companies and have owned my company for a total of 25 years. I am a corporation that serves mostly St. Joseph, Indiana. And surrounding cities. I believe in quality and that will bring quantity. I charge less than the average going rate in our area because I limited my overhead. My customers become my friends because to me it is more than just a job. It is  an opportunity to help people and get to know them. Thank you
