🛠️ DIY AC Compressor Conversion & System Overhaul

🛠️ DIY AC Compressor Conversion & System Overhaul Today, I undertook a full DIY upgrade of my AC, converting the old piston damage compressor to a scroll compressor. This was a complete mechanical, piping, and electrical overhaul. 😎💨 Step 1: Removing Old Components 🏗️ • Removed the condenser assembly and piston compressor from the outdoor unit. • Disconnected and removed old system wiring, capacitor, and contactor. • All electrical connections were carefully terminated using crimp terminals for safety. 🔌⚡ Step 2: Preparing Piping & Brazing 🔧🔥 • Designed and fabricated new suction and discharge piping to match the scroll compressor configuration. • Used same pipe sizes: 1/2" for suction, 7/8" for discharge. 📏 • Aligned and installed the compressor with proper mounting legs and bolts, including anti-vibration supports. • Connected nitrogen for purging while brazing all joints to prevent oxidation. 💨 Step 3: Cleaning & Flushing the Condenser 💧✨ • Installed service ports on the condenser lines. • Flushed the condenser using R141b, removing moisture and old oil. 🧴💦 • Discovered some contamination, cleaned the condenser thoroughly, then removed the service ports. • Reinstalled the condenser and re-brazed the condenser pipes using nitrogen purging. 🔥 Step 4: Replacing the Filter Drier 🛠️ • Cut out the old brazed filter drier. • Flared both pipe ends using flare nuts to fit the new drier properly. ⚡ • Ensured proper sealing to prevent leaks. Step 5: Electrical Work 🔌 • Replaced all system wiring, capacitor, and contactor. • All connections made with proper crimp terminals for safety and reliability. Step 6: System Preparation & Flushing 🧊 • Isolated the outdoor unit and flushed the entire piping system with the indoor unit using R141b. • Verified the system was completely clean, free from moisture and contaminants. • Performed deep vacuum to remove any remaining moisture and non-condensable gases. 🕳️💨 Step 7: Charging & Adjustment 📊 • Started refrigerant charging for the new scroll compressor. • Carefully adjusted superheat (SH), subcooling (SC), and system pressure for optimal performance. ⚠️ Note: This was a DIY project, done step by step with proper tools, nitrogen purging, and safety measures. ✅ #DIYAC 🛠️ #HVACRepair 💨 #ACUpgrade ❄️ #CompressorConversion 🔧 #ScrollCompressor 🌀 #Brazing 🔥 #SystemFlushing 💦 #DeepVacuum 🕳️ #ElectricalWork 🔌 #ACMaintenance 🧊 #DIYProject 😎
