Meet Tom O’Connor

tomIn 1969 after I was honorably discharged from the Navy due to an old injury, I was anxious to start a family. I started to do handyman jobs in the Brandywine subdivision of Villa Park. Two years later, I started Shamrock Heating & Air Conditioning along with my wife Kathy. Together we faced many challenges in growing our business, but one thing always remained the same. Never do anything that is not in the customer’s best interest! This is something that is hard to come by in the heating and air conditioning industry, so this was greatly appreciated by my customers. Over the years, my business has grown, but I have always stayed true to my policy of being honest and making sure that my employees do the same. After all, I need to be able to sleep at night too. My sons (Tom Jr. and Will) are now both working with me and they believe this with all their hearts, so as we continue to grow, we will not back down from this basic philosophy.
