Howdy:
Just had a new HVAC system installed (furnace & AC). The old system was 19 years young. The outside AC was a Janitrol and the inside bit was a Carrier. I had kept it together with duct tape and bailing wire, but parts availability bit me in the tuckus in the middle of a cold snap. Anyways, replaced them with a low-end Trane setup.
The new furnace/blower unit sits on top a filter chamber doohickey with a flip-forward little door. I was used to installing a single 14x25x1 filter, but this new chamber deal accommodates two of them, with little tracks for both or one 2" filter
My question is ought I supplement the pleated paper filter with a spun fiberglass filter just before it? I thought it might help keep dog hair from getting into the A-coil and extend the life of the pricier pleated filter. Cleaning the A-coil on tghe old unit was a bear.
