I have a filter at the base of my air handler (in the garage). I have an AC intake inside of my house. This intake does not have a filter and is looking very dusty (the cover and duct inside). I was told by an AC tech not to put a filter there because it would make the AC work too hard - it was designed to have one filter. This does not make sense. All the contaminants are getting into the AC ducts. If if most are stopped by the filter at the air handler. Should I have a second filter?
