Hi,
I moved into this (new) house just under 9 years ago and the air conditioner has stopped blowing cold air. A repairman came out a little while ago and said that the coil may need to be replaced (for $1,800) and that coils typically only last 5-7 years. I know that A/C repairs tend to be expensive, but is that a reasonable price (the unit is a Lennox 10AB48) and is it true that coils only last 5-7 years? That doesn't seem very long to me, but then I don't know much about it. Anyway, he couldn't do the work tonight because the coil was frozen (?) but is planning to come back tomorrow morning. I'd appreciate it if anyone who knows about these things can give me their opinion based on what I described.
Thanks in advance.
