I have a Carrier Super Saver / Lennox furnace and central AC unit, and they seem to date back to '83 or so (Carrier S/N is U3C31187). We just had our first problem ... the AC drain clogged and so the drip tray overflowed.
I blew out the drain line, so the system is running again. The water on the basement floor is no big deal, but it seems that some also dripped into the blower. It's not as balanced as it used to be. It's not shaking out of the mountings, but it's going to need to be repaired or replaced so that we don't lose it this winter.
While exploring the leak, I found corrosion in the drip pan. The fill valve on the condensor is broken (closed) so I can't add more R-22 without opening the system. But, it's cooling OK and not freezing the coils. So, I could replace the blower motor and fan, and I could replace the drip tray. What are some other things I should look for in the repair-or-replace quest?
What might I expect to pay for a new furnace and AC, installed? My heating and cooling bills have been reasonable - I might be able to save $50/month, so that alone isn't a selling point.
Thanks in advance for your great advice,
Glenn Liston
