Returned to a home in Philadelphia, PA 19145 for a follow-up visit after his recent heating tune-up to address performance concerns. Upon inspection, our technician discovered the system had no condensate trap installed—a key requirement for proper drainage on air handlers. Additionally, the high-voltage wiring was incorrect, and the system was overcharged with refrigerant, affecting efficiency and reliability. We provided a full assessment with recommendations for corrective work to restore proper operation and long-term system health. The customer now has a clear plan to ensure his system runs safely and efficiently through the season.
