Completed QA for 80,000 BTU standard efficiency furnace install. AC is 3 Ton Heil that dates to 2022 installed by another contractor. They had gotten an alert that furnace was not running overnight. Had error codes for open high limit. 16x20x1 filter was dirty and fan speeds for heating were low (TAP 2 which is 800 CFM) Changed gas heat stage 1 fan speed to tap 4 (1100 cfm) to and gas heat stage 2 to tap 5 (1300 cfm) Set cooling fan speed to tap 4 as well to target 1200 CFM for 3 ton AC capacity. Set heating fan off delay to 2 min 20 seconds. Inspected all aspects of install: mechanical wiring, control settings, flue and gas piping. Verified gas pressures. Measured temperature rise and static pressure on both stages of heating Combustion and draft tests: Pass Install fails QA because the fan speeds were so far off from correct. Caused a no heat issue the day before QA and there would have been a no cooling call because cooling fan was set way too low.

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. Thank you, Kurt, for your outstanding service!
