Did you replace your four inch filter with a normal size filter (1" thick)? Can you explain more about this custom frame. Can you now buy filters from the big box store or normal retailer? Do you feel your system now is better than before? Thanks for your help!

Just because a filter looks clean doesn't necessarily mean it is. Hold a used filter up to light and compare it with a new one.

I replace my filter every three months.

Can you provide a little detail in how you changed the air return grill? This sounds like a great thing to do.

Trane furnaces have a very poor design where the air filter is installed and it is very easy for air to bypass the filter. Especially an expensive one that can bend in toward the blower fan.

we haven't been down since June but the filter can't remember if the filter was changed. Going down again mid sept, so will check it then. I think we brought them back up here and they got changed when we got back. we have a frame up here, but needed one down inTV. it was awhile ago so can't remember the details but I know he was still there when's we were there in May. you mày be able to get them from HD or Lowes. hope this helps.

I went online to purchase my AC filters. The filters were delivered very quickly.
