Mike did an amazing job fixing our broken AC on a hot Sunday in Austin. He explained the problem and its solution very clearly and even did some extra maintenance for us. Fantastic experience! We have been very happy customers of McCullough Heating & Air Conditioning.

Michael came out on an emergency call and accurately diagnosed our leaking air conditioner unit and made suggestions to repair and alleviate the source of our problem. He was punctual, professional, and had follow up repair work scheduled upon completion of the service call. McCullough always comes through for us.
