"One hour heating and air conditioning of O’Fallon exceeded my expectations! The representative Keith was kind courteous, and showed up early. He was very neighborly and I enjoyed our small talk. He even sprayed out the air conditioner with my garden hose for no additional cost. He deserves a raise! I highly recommend this company."
