So heres another post about the residential teacher vs refrigeration teacher. Our current teacher (refrigeration teacher) told us we can use a wire brush to clean the evap coil if its dirty but my old teacher(residential teacher) told us we couldn't use a wire brush because it will damage the fins on the coil. Which one is correct???
Sorry about these kind of questions our old teacher had 40years experience on residential and new teacher has 25years of refrigeration and to me i see that the old teacher has alot more knowledge then the new one so i turn to you guys for assurance.
