I have a 20 year old OEM Lennox G-16, 5 ton, 60% AFUE, Gas Furnace and 4 ton, 9 SEER, AC. The furnace was inspected last fall and is OK. The AC had its first inspection in probably 5 years or so. It is very low on freon. Don't know if it leaked out slowly over a period of years or sprang a big leak recently.
Anyway, the tech said he could run a leak trace for $XXX and the most common source of the leak is the coil, which would cost near $XXX to replace. He also could just replace the freon, which he estimated at needing 7 pounds and costing about $XXX or so.
Also, I have a fiberglass hammock filter. Several years ago, I added a standard 20x25 fiberglass filter as a duplicate system so I only had to change the hammock once a year and changed the 20x25 monthly or so.
Last AC season, I replaced the 20x25 with a pleated type paper filter. Everything was OK until switching to the heating season. Started blowing the 20x25 pleated off its homemade mount. Tech said it might be too much in combination with the hammock for heating even though OK with AC. Switched back to the 20x25 fiberglass, which then blew out a couple of times but seems to have been OK the last few months.
Anyway, my main question is repair or replace? I'm in the Kansas City area (hot & humid summer and cold winter) and am looking at a 13 SEER or so heat pump and 80% gas furnace. If you do suggest repairs, what needs repairing?
That you in advance for any assistance you can provide.
