I am writing this review with all honesty and sincerity. My 30-year-old air conditioning unit was leaking refrigerant and my unit would stop working. I spoke with Luis Ortiz and he came to evaluate my system. He came back with an estimate that was amazingly fair. What most impressed me was their prompt and courteous service. They promised to keep my house cool until the new unit could be installed…and they did! All the people who came to service my home were so helpful and responded in a very expedited manner. Luis, Justin, various service people, and the installers Andy and Jarvin could not have made this major job any easier. If you should ever need air conditioning service or a new unit, please consider Burkholder’s! They are definitely the air conditioning company in the Lehigh Valley that you want to do business with!
