My central AC a 1996 Lennox 3 ton stopped blowing air yesterday, I looked at the air handler coil and it was frozen, filter is new and a
4" so I let it thaw and ran it without the filter thinking added airflow would help. In about 40 minutes it froze again. Airflow unfrozen hasnt changed, its the same out the vents as always so I dont think the blower is bad or any restrictions. When an old unit leaks freon is that usualy the end of life of the compressor or air handler, is it often possible or easy to find and fix a leak without spending alot. I will call a tech today and I hope the leak is small enough that it will last the year but a few days ago it was fine. Will I damage anything running it low on freon for about 30 minute cycles till it starts to freeze and let it thaw, a bit of cool air still comes out.- posted
