2. Total Cost of Ownership: Include maintenance (e.g., $0.03/ton-hour for tube cleaning), water treatment, and refrigerant phaseout risks (e.g., R-22 bans).
3. Scalability: Opt for modular designs like Trane’s AdaptiView™ for future expansion. A modular plant can add 200-ton increments without downtime.
4. Noise Levels: Air-cooled chillers above 85 dB may require sound enclosures, adding $15,000–$30,000 to project costs.

  Pro Tip: Use ASHRAE’s Building EQ tool to simulate chiller performance under local climate conditions. For Phoenix, AZ, a water-cooled chiller with adiabatic cooling may outperform air-cooled models by 25%.
