Heat Pump age

I just completed an inspection on a house that had a Heat Pump with a tag showing only a Manufacturer’s code number. The tag was really hard to read because of the positioning of the heat pump itself but the code was NCH5530VKA1. The serial number L933510466 and the model number was 30MHB-000092CR. Anyone know the manufacturer?

Also, I used to have information on my computer that gave info re: the interpretation of various water heater, furnace and AC manufacturer’s serial numbers. Just changed computers and can’t find it - any help in that area would be appreciated.


I’m absolutely no help without the manufacturer’s name.

Thanks Russell, I appreciate the response.


1993 is my guesstimate with out manufacturer info
