Hi, I've been in my house for a year, I looked inside all of the interior air intakes for my central air system, and none of them seem to have a filter. I was in the crawl space yesterday and saw what look like used filters, left by prefvious owner. Do all Central air systems have filters? If the filters is not in the intakes where are they? The machinery of central air system is in the crawl space, is the filter located in this part of the system? Thanks.
