My outside A/C unit runs fine and the fan inside the house runs fine as well, but there is absolutely no air coming through the vents. I changed the filter but this is about the extent of my A/C knowledge. Can anyone tell me what the problem may be and how to fix it? Thanks!

Is possible the evaporator coil is froze over, therefore the air from the indoor fan can`t get through,, or so dirty that again air can`t get through

Is that something I can fix on my own or do I need to call a pro? If I can do it myself, how? Thanks!

Look out side at the copper lines and the unit and see if you see ice. If so turn the t-stat to fan on and the cooling off. Was the air filter really dirty when you took it out? If not you may need freon! Which you can not do yourself.
