🔧 Why Whole HVAC System Replacement Is Required with New Refrigerants

❄️ 1. Old Refrigerants: R22 - Banned for production
R410A (Puron): Still used in many homes, but being phased out starting in 2025 under new environmental regulations .

💨 2. New Refrigerants: R-454B and R-32
These are the next-generation refrigerants approved for new HVAC systems starting in 2025.

🔁 Why You Must Replace the Whole System:
🚫 New Refrigerants Are Not Backward Compatible
You cannot use R-454B or R-32 in systems designed for R410A or R22.
The compressors, expansion valves, pressures, and chemical properties are completely different

✅ So What Needs to Be Replaced?
If your system uses R22 or R410A and you're switching to a new refrigerant, you’ll need to replace:

🌀 Condenser
❄️ Evaporator Coil (Slab or Box Coil)
🔥 Furnace or Air Handler
♨️ Heat Strip (for electric heating systems)
🧵 Line Set (may need to be flushed or replaced)
