    How we ranked these brands

    • Efficiency — published part-load ratings for commercial chillers, not marketing peaks
    • Reliability — what we see in the field across NYC and Long Island buildings
    • Parts & service network — how fast parts and qualified techs reach a NY metro job
    • Controls & LL97 fit — building automation integration and an electrification path

    Ratings, efficiency, and warranty terms vary by model and change often. Confirm current manufacturer specifications for your exact model before specifying.
