Eeh, filters are not exactly "internal" parts lol.Hmmm. I change the filter every 3 months. Haha. I do check every month or so to make sure nothing looks out of the ordinary. Its a Lennox and the tubing is whatever they use in new houses these days in texas.
Anyway the tubing usually is sold (in my country) in 2 versions..
the cheap with crappy aluminium. (retains cold very little and can break way too easily)
and the copper one (way more durable and more efficient)
aluminium usually starts to leak after the first year of installation.
the aluminium ones are loved by mass house builders.. so they can boast they have AC units in every room, even if only half of them work properly due of shoddy quality and installation.
