Q I need help specifying a high SEER roof mounted commercial HVAC system of 25 tons cap. Dual stage compressor, make up air, and energy management systems should be built in. Do you have any suggestions?
A I have located some information that should assist in your quest to find the best system for your location and application. The first resource I recommend is from Pacific Gas & Electric (PG&E). The publication, “Efficient Packaged HVAC Systems for Commercial Facilities,” is a great resource for recommendations, manufacturers, and other related information. The next highly regarded resource is the ARI Directory of Certified Product Performance from the Air-Conditioning & Refrigeration Institute. Also for download is “Operations and Maintenance Best Practices…A Guide to Achieving Operational Efficiency Release 2.0.”
