I recently began renting a home that uses a gas furnace to heat it.
I've never used gas heat before and had some questions about filtering
the air. If I understand correctly the furnace has a filter that may
need cleaning or replacing that is directly attached to the furnace. My
question is should I also filter the cold-air return that is on the
first floor of my home? Also near the air-return is another large grate
that to me seems to serve no purpose, (ie, no air seems to move through
in either direction) could I cover that large, ugly grate with a rug?
//best ask your landlord this question..... //
My landlord seems to know absolutely nothing about the house. The house
is a duplex and she said that there is a filter in the floor on the
other side f the house, but isn't sure where the filter on our side
//how old is house? big old grate might be leftover of former heating
IMHO the larger great is a remnant from an older system.We no have
ducts running to registers in each room upstairs and down. And no air
seems to flow through the gate when the heating system is running. If
this is the case (the landlord doesn't know, see above) I should be
able to cover the large grate, correct?
//It's interesting, but one can't tell from the original post if he is
the landlord or the renter.//
I am the renter, by the way.
Filtering is done on the low pressure side, before the fan. Filtering before
and after will only reduce the air supply and cause problems.
If no one knows then call a pro and have the unit checked out. Ask the pro
your questions while he is there. You will know that the unit is safe and
your questions will be answered.
