Goodman Furnace

Anyone know age and btu’s?
Goodman Electric
A36-15 or
Doesn’t show up in Prestons.


**Goodman **First two digits of the serial number are the year. Second two are the month.

Btu rating is model number…i.e.; GMP075-3 (75,000 bonnet input) Compressor is same: serial # 9709088872 (yr1997 wk 09)

Tonnage is model # CK361C The first two numbers after the CK (letters) divided by 12 is tons. i.e.: 36 div by 12= 3 tons.

So based on this info, I would say it’s either 36000 or 35000 btu. That seems very small. I didn’t know they made them that small. You sure this isn’t an air conditioning unit? 3 Tons?

A36 would be a 3 ton Goodman air handler.

You would need to determine the KW of the strip heaters.
