Direct Replacement HVAC units are a Seasons•4 specialty. We can custom-engineer an HVAC system for almost any need. Seasons•4 excels at finding ways to upgrade old systems to provide better performance and efficiency while yet still meet the original footprint and match existing utilities.
Direct replacement multi zone units:
Seasons•4 is the largest manufacturer of direct replacement multizone units in the United States, manufacturing replacement units for older Carrier, Nesbitt, Lennox, and Trane multizone units as well as many others. Our units are built to match the existing curbs and utilities minimizing downtime allowing for quick and easy renovation projects. We have improved greatly upon the design and functionality of the older versions by utilizing direct drive blowers, modulating gas furnaces, modulating scroll compressors that reduce energy consumption while not sacrificing space comfort. We build two deck, three deck, and three deck vav versions of all units and many can be provided with energy recovery as well and still maintain the existing footprint.
Direct replacement for school markets:
Seasons•4 is a leader in direct replacement of old obsolete HVAC equipment for K-12 schools throughout the United States with some of the largest school districts relying on us for their replacement needs. Approaching school retrofit HVAC projects from a direct replacement standpoint can be beneficial to all parties.
