I just installed a Friedrich unit I found on craigslist for $150. I am so proud of my self. This is a 23K btu / 12A unit. I have a serial number of LGER03870 and a model number of KM24L30-B
Is this a good unit? Anything common problems with Friedrich units?
How do I read the serial number to find when this unit was manufactured?
(The seller told me it was only 3yrs old)
