AC Maintenance Start PCSA 2025 a/c check up Completed cooling maintenance, cleaned coil, flushed drain, filter is provided by customer, checked system operation, found blower capacitor starting to leak oil, explained to customer about potential blower capacitor failure and recommended replacement and got approval. Replaced capacitor and found no more issues with system operation. Customer also had concerns about master bedroom not cooling as well as the other rooms closer to the furnace, explained to customer that ducts lose air velocity through the length of a “duct run” and is normal for this to happen. Customer would like to look into a possible solution to this issue by getting a fan booster or maybe some more insulation in the attic, customer would like an estimate for potentially more attic insulation System is cooling at this time
