Holtzople does excellent work. We purchased a complete geothermal system from them as part of a remodel in 2013. Ever since then our electric bill has been in the range of $118 – $156 per month. That represents a greater than 50% reduction from before when we had older systems. Every 6 months they come out to do maintenance and tune up work on the system and keep it in tip top shape. I’d like to recognize Kevin, the guy who usually does the work. Today he was actually a little ahead of schedule and called to see if it would be okay to arrive early – heck yes it was ok! Kevin is amazing in that he has so much energy and so much knowledge about the system. He explains what he’s doing and asks if I have any questions, which I frequently do have, and then he gets right to work. Kevin is easy to talk to and has a good ability to explain stuff to me so that I can understand it. I really like that. My wife and I are thankful for having decided to do business with Holtzople Heating & Air Conditioning. These folks have integrity and professionalism. We highly recommend them.
