About Coleman HVAC Systems
Coleman makes camping equipment, but Coleman HVAC has no connection to that business. It's a licensed brand name used by York International, a Johnson Controls company, for a line of residential heating and cooling equipment. Coleman HVAC covers central air conditioners, heat pumps, and gas furnaces aimed at the residential replacement market. The serial number format is identical to York, a letter-based date code in the first two characters that maps to specific year and month values.
