Hello, Two days ago our AC stopped blowing cold air. We turned it off overnight and tried the next day. Same thing.. still only the fan works.. no AC blowing cold. So I checked the breakers.. and they all work fine. I went out side and noticed that cold air was coming out of the Lennox unit. The unit is from 2001. Today we called support.. everyone wanted $80 to come out.. but we found one guy for $20. Not sure how knowledgeable he was because he sounded a little unsure. He said that we need to replace our compressor.. and that he recommends we just get a new unit bc the price is not much different. He quoted us $2800 for a new 2.5 ton unit.. we called around and found one for $2100. Still outrageous. I can't afford that and my parents are gone on vacation for 2 weeks.. is there any thing I can do on my own?
