i am a service technician and applied for professional membership a while ago. i guess you only induct new ones once a year or something. so thats why this isnt in the pro forum.
i have a Bard package unit that sits 4 inches away from my dryer outlet. this particular design unit draw condenser air in from the side and pushes it through the coil. needless to say, its now plugged with lint, and running 400+ head pressure.
the coil is deteriorating, just a little bit, from previous cleaners, but im going to have to clean it again. this time though, id like to change the fan blade and make it pull air through the coil, for several reasons.
1 this should reduce/prevent further lint ingestion
2 make future cleaning easier
3 hopefully operate better with a clean breathing coil.
i imagine the air pulls through the coil better then it pushes. i gather equipment manufacturers learned that one the hard way since most older units i remove push air through the evaporator and none of the new ones ive worked on do it that way anymore.
so, am i looking at any unforeseen problems before i buy some coil cleaner and a fan blade, and move air the opposite direction of the manufacturers intentions? im not worried about a SMALL drop in performance if there is one. the system cant meet demand as it is now. its not an old unit ether. its just a crap setup. right next to the dryer vent and getting south west sun shine all through the hottest parts of the day maybe ill take some picture of this winning setup and share them later on.
