### **Cons**
1. **Higher Upfront Cost**
- More expensive than **reciprocating compressors** of similar capacity, though the long-term efficiency gains may offset this.
- **R-454B refrigerant** is pricier than older refrigerants (e.g., R-404A), increasing initial system costs.
2. **Refrigerant & Compatibility Challenges**
- **R-454B is a newer refrigerant** with **higher cost and potential supply chain issues** compared to established options.
- Some **older systems may require modifications** (e.g., oil changes, filter-drier replacements) when switching to R-454B.
- **Not all service technicians are fully trained** on R-454B, which could complicate repairs.
3. **Single-Phase (1PH) Limitations**
- **Lower power capacity** compared to three-phase (3PH) compressors of similar size, limiting use in high-demand applications.
- **Less efficient at very high ambient temperatures** (e.g., > 104 F / 40 C), which may require additional cooling measures.
- **Not ideal for continuous-duty 24/7 operations** without proper sizing and cooling.
4. **Sensitivity to Electrical & Installation Issues**
