First time poster We are moving our 5-Ton A/C system. The existing system is a Trane XL1000 condenser and XL80 Furnace about 9 years old. The Furnace and A-coil is currently in the garage and it is going into the attic. Condenser will stay outside.
We need a new a-coil because the furnace will be sitting on it's side instead of upright, so this is a good time to consider replacing the outside condenser. Our furnace is in excellent condition and we love the 2 stage system, so that's staying. I have an AprilAire 2400 for the air filter.
1) The re-located system will now be sucking air (return air) from the ceiling instead of the wall. Should I stay with our AprilAire 2400 air cleaner or install the grill type with door that have space for 2 inch filters? With the AprilAire 2400 I would have to go into the attic for filter changes, while with the grill type it's easier since I just open the grill and replace the filter.
2) What is the best platform to sit the furnace in the attic to reduce noise / vibrations? The furnace may sit close to our bedroom so I am concerned with vibrations transferring down the wall and into the bedroom / living areas?
3) I like to install a UV Light of some sort for air purification. What's recommended in terms of best bang for the buck?
