Included in the manufacturers listed are also makers of ancillary equipment such as controls, circulator pumps, etc. Heat pumps are discussed at The Carson Dunlop Technical Reference Guide provides both equipment data tag decoding data and also manufacturer contact information as well as historical dates for many brands of heating and cooling equipment. Email Building Intelligence Center, Copyright 2014 all rights reserved Providing resources for research and education! It is often in the last three to five digits, but is sometimes closer to the middle. The Air Conditioner Serial and Model Number Tells Hvac model number tells you: Types of hvac unit, refrigerant types, hvac ton, voltage, compressor series, seer rating, and other thing. Information below refers to commonly used codes.
Beginning in 1970 Carrier began to use a letter followed by a single digit year. Sketch at left on guessing the size of an air conditioner system is compliments of. You will usually find this data in the bright yellow EnergyGuide sticker that is more often on a side of the equipment rather than encoded in the equipment's own data tag.

Model numbers and serial number appear to have been cut away from the data tag. Because fusing an air conditioning compressor at the minimum level can result in blown fuses or tripped breakers during these intervals of heavy current draw during compressor startup, compressors are either protected by a slow-blow fuse or a somewhat larger than minimum circuit breaker.
