“I'm writing to let you know that we are very pleased with how our project turned out. Your men did an excellent job for us! Their professionalism, politeness and knowledge of their trade is why we've been doing business with Bill Leary Air Conditioning and Heating for the past 15 years and will continue to do so.”

First United Methodist Church - Union County

"Bill Leary AC and Heating has been the official service provider for the Somerset Patriots for over 10 years and are great Partner and an integral part of our team. When something breaks during a home game, we need to be up and running right away and the entire staff there always does an amazing job making sure we are up and running. Any time we need service, their tech team knows our facility inside and out and I open up the doors and they take care of the rest and I can go about my day without worrying about a thing! If you're looking to replace your current service provider, Bill Leary AC and Heating would be my recommendation! "
