@cidtelesusa: What’s the normal pressure and temperature for an R-22 residential system? Let’s break it down. R-22 systems operate based on the refrigerant’s pressure-temperature chart. 📊 This tells you the saturation temperature at a given pressure — and it’s how you know if your system is working right. 🌡️ On a warm day — around 85°F outdoor temperature, here’s what you should see: ✅ Suction Side (Low Pressure) 🔧 Pressure: 60 to 75 PSI 🌡️ Saturation Temperature: 32°F to 45°F 🌀 This tells you the evaporator coil is cold enough to absorb heat — but not freezing. ✅ Discharge Side (High Pressure) 🔧 Pressure: 200 to 250 PSI 🌡️ Saturation Temperature: 95°F to 120°F 🔥 This means the condenser is hot enough to release heat to the outside air. 💡 Why does this matter? Because if the suction pressure is too low, it could mean: ❌ The system is low on refrigerant 🚫 There’s a restriction 🌬️ Or airflow is poor across the evaporator If the high side pressure is too high, it could mean: ❌ The system is overcharged 🧼 The condenser is dirty ⚠️ Or there’s non-condensables in the system ✅ Always check both pressure and temperature. Then compare them to the R-22 PT chart to understand exactly what the refrigerant is doing in the system. 👍 Like this video and follow for more HVAC repair tips! #r22refrigerant #hvactips #airconditioningrepair #ptchart #hvactraining
