Best Commercial Packaged AC Units 2026: Daikin, Goodman, Trane and Carrier Compared
The definitive 2026 guide for HVAC contractors specifying commercial packaged air conditioning.
Selecting the right commercial packaged AC unit involves balancing efficiency, reliability, cost, and AIM Act compliance. With the 2026 HFC phase-down in full effect, every new installation must use approved low-GWP refrigerants.
This guide compares the four most-specified brands for commercial packaged AC: Daikin, Goodman, Trane, and Carrier. We evaluate each on SEER2 efficiency, tonnage coverage, refrigerant compliance, warranty, and total cost of ownership.
All units are available tax-free through ClimateProDirect with free freight on orders over $999.
