Thank you Jesus that my a/c is back on. and thank you Holtkamp. Brandon wasn't just "on time, " he was early! and he quickly identified the blown capacitor and fixed it. It was a hot weekend and now we are cool in body and minds thanks to Holtkamp. this is the first time we had to use them for a repair but for 15+ years they have provided maintenance and it is a pleasure to write this review for a company that does such excellent work.
