Testimonials Holtzople was excellent.  Everyone I came in contact with was extremely professional.  Brad, Matt, Jerimiah, Andre, Melissa, and Kelly were all a pleasure to work with.  The work was completed on time.  The staff worked as a team and built on the expertise of one another.  They were more than willing to answer questions and provide instruction on the use of the system.  I felt that they were there for me and not rushing out to another call.  The job site was cleaned after the work and looked better than when they arrived.  I highly recommend Holtzople for all of your cooling and heating needs. Robert SiepielskiWaynesboro, PA Holtzople’s technician arrived promptly, donned his plastic booties and came into the house to check out my air conditioning system problem. He quickly found the bad part, replaced it and checked the refrigerant. After he was done, he explained the problem, showed me the faulty part and explained their charges. He was courteous and kind. I was very pleased to have it fixed so quickly! I would recommend this business to anyone. Linda LeonardSharpsburg, MD Holtzople was excellent.  They fixed my air conditioner at start of current heat wave.  They served me with a quick response time and they came out a second time at no additional expense (to review concerns I had about drainage).  Inspected drainage system same day as requested and found no problems but gave us peace of mind.
