🛠️ Indoor Unit Overhaul – Complete Service Report

🛠️ Indoor Unit Overhaul – Complete Service Report 1️⃣ Initial Condition Inspection 🔍 • Indoor unit found with heavy dirt accumulation on evaporator coil • Blower wheel contaminated with dust and oil • Evaporator bracket holder heavily rusted • Reduced airflow causing low suction pressure and poor cooling performance 2️⃣ Electrical Isolation ⚡ • Power supply disconnected and unit safely isolated before servicing 3️⃣ Complete Disassembly 🧰 • Removed front panel, filters, drain tray, and blower assembly • Accessed evaporator coil for deep cleaning 4️⃣ Chemical Cleaning – Evaporator 💧 • Applied CoilSafe cleaner (1:3 dilution) to evaporator coil • Removed dust, grease, and oil deposits • Coil thoroughly rinsed and dried • Result: Improved heat transfer and airflow ❄️ 5️⃣ Blower Motor & Wheel Service 🌀 • Blower wheel removed and cleaned • Blower motor shaft manually rotated • Applied rust-penetrating lubricant to ensure smooth bearing operation • Verified free and balanced rotation 6️⃣ Corrosion Treatment 🧱 • Evaporator bracket holder found severely rusted • Rust cleaned and anti-rust primer applied to prevent further corrosion 7️⃣ Drain System Service 💦 • Drain tray cleaned and flushed • Drain line checked for blockage and proper water flow 8️⃣ Reassembly 🔧 • Reinstalled blower assembly, filters, and panels • Ensured proper alignment and secure mounting 9️⃣ Operational Testing 📊 • Tested blower speeds (low / medium / high) • Verified smooth motor operation • Checked airflow and noise level • Confirmed overall indoor unit functionality ⚠️ Diagnostic Note Restricted airflow due to a dirty evaporator can cause low suction pressure, which may lead to incorrect refrigerant charging. Overcharging increases compressor load and discharge temperature and may result in compressor failure. ✅ Final Result • Evaporator coil cleaned and restored • Airflow significantly improved • Blower motor running smoothly • Corrosion treated and protected • Drain system functioning properly • Indoor unit operating at optimal performance 🧊 Status Indoor unit servicing and restoration completed successfully. #IndoorUnitService #EvaporatorCleaning #HVACMaintenance #CoilSafe #BlowerService #ACOverhaul #AirflowRestored #HVACTechnician #DIYAC 🛠️❄️💨
