Default How do I change my AC/furnace filter(s)?

In article . com,
says...
3 years ago, I had a complete HVAC cut-in on my house. They installed a
Lennox 12ACB air conditioner, a Lennox G40UH gas furnace, and an
Aprilaire 2400 air cleaner. The systems all run great, but I've never
changed any filters. Where are they is the question? I see that the
Aprilaire one is easy to change. Is there also one on the A/C or
furnace unit?


It sounds like the Aprilaire is intended as a whole-system filter, you
may not have any other filters to change. That's how our house is set
up, a Honeywell electronic air cleaner in-line with the furnace, no
filter in the furnace, just the air cleaner unit.
