I knew they were good, but I did an inspection on one yesterday, that once I checked Preston’s was 37 years old and still worked strong. AC had a TD of 17, htr was blowing about 115 (Gas).

Although the Lennox systems (older ones) did not have a mfg date on them, it was not hard to tell it was old. The phone # for the Company that installed it (still in business) was MA-4010. ![icon_lol.gif](upload://zEgbBCXRskkCTwEux7Bi20ZySza.gif)
