I called on a Sunday and Rick was out of town but still answered his phone. He gave me some pointers on things I could try to do to fix my Central Air unit. Nothing worked. I called him back again Sunday night, He answered. I asked if he would be back in town the next day. He said he could be here at 10AM. He was! He spent at least 6 hours working on our unit and charged us for 2 hours. Fantastic high quality service! I will be back for all of my Central Air services!
