How to Clean 1984 TRANE Cooling VENTS inside house No Manuals

You need to take the cover off and you should see some aluminum fins like whats on the outside unit the blower will either blow across them or pull air accross them. Clean them with a wire brush and soapy water if you dont have coil cleaner which can be purchased at hardware stores

the cooling coil is very delicate i reccomend you call a professional to have it cleaned.

The Outdoor unit will be easy 1st diconeect power at panel, or disconnect box near unit. Remove top of unit, be careful not to damage fan blades. Spray coils (fins) with a light degreaser let is soak for 5 mins. wash out coils from inside the unit out. Spray straight on so you push the dirt out the other side.

Re assemble and start up.

Indoor coil will be accessed by removing front cover and you may have another cover to expose the inside of the coil fins. That is where you need to clean. Spray degreaser on coils and rinse off. If its gunked up then use a wire brush 1st. Carefull not to bend the fins over.

Check the drain pan at bottom of the coil to be sure it's not full of stuff. Blow out if needed.

You should be clean and ready for the season
