A multi-story building required changing out 2 floors of occupied space. Each floor required 80 tons of cooling. UCA was able to provide one 60 ton and one 20 ton EZ-Fit VAV for each floor. The modularity and small footprint of the units allowed this retrofit to be easily completed over the weekend. Not only did the owner save money on the total installed cost, he also received an energy rebate of $25,000 based on the higher IEER value of the units.
