Return visit for leak search. UV dye was added to the system in October. I look for dye using UV light and could not pinpoint leak at indoor coil, outdoor coil or my accessible brazed joint at this time. *Lineset runs above drywall ceiling and soffit in basement. 60+ feet. Found system running g at 103 psi with 35+ Superheat and almost 0 Subcooling. Discussed charging the first floor system needed refrigerant and becoming plan member for both systems. Homeowner agreed, System needed 53° OZ r410A. *Factory charge is 105oz. Lineset is 60 feet or so so total charge is 8.25 pounds. So system had lost approximately 40% of its charge. 1st Fl system refrigerant data before charging: 251/103 39SH 0.5 SC 1st Fl system refrigerant data after charging: 288/132 10.5SH 6° SC *Outdoor temperature 73° (light rain and thunderstorms) *She wants to wait to do AC tune ups in next calendar year that way we can check refrigerant dye at that time. First floor system operating ok now that it is

Subject: Exceptional AC Service from Kurt - DiBiase Heating and Cooling company -Highly Recommended! I am writing to express my sincere gratitude and highly recommend Kurt for his outstanding service during a recent issue with my air conditioning unit. From the moment he arrived, Kurt demonstrated a remarkable level of knowledge and expertise in diagnosing the problem. He quickly identified a refrigerant leak and clearly explained the technical details in a way that was easy for me to understand. What truly impressed me was Kurt's transparency in sharing information. He didn't just state the problem; he took the time to show me the evidence of the leak and thoroughly explained the potential causes and consequences. This level of openness built trust and allowed me to feel confident in his assessment. Furthermore, I greatly appreciated Kurt's patience in discussing the various options available to me. He patiently walked me through each potential solution, outlining the pros and cons, and answering all of my questions without ever making me feel rushed or pressured. His ability to explain complex technical information in a clear and concise manner was truly commendable. Beyond his technical skills and communication, Kurt showed a genuine willingness to go above and beyond to assist me in deciding the best next steps. He didn't just offer solutions; he took the time to understand my needs and budget, offering insightful advice to help me make an informed decision about how to proceed with the repairs. His commitment to ensuring I felt comfortable and confident in the chosen path was truly exceptional. Thanks to Kurt's expertise, transparency, patience, and willingness to go the extra mile, I feel confident in the next steps to fix my air conditioner. He is a true professional and a valuable asset to your team. I would not hesitate to recommend Kurt to anyone in need of reliable and trustworthy AC service.
