WOW! I called Cool Air USA on a Saturday and they showed up like they said they would on the same day. The technician did a great job and had my a.c. working again. He explained everything he would be doing from start to finish. Excellent, immediate service during the hottest summer ever, this company was amazing. Courteous, clean and extremely explicit instructions care instructions, reasonable and competitive in pricing and patient when it came to answering my questions. Will definitely call them next time!! Highly recommend to others!
