I'm looking to replace my decades-old furnace with one to qualify for the tax break. I've got central air, which is newer and that we use only a few times a year. Do I have to -- or is it a good idea -- to replace the AC when I replace the furnace? WHat are the issues involved? Thanks.
No You would have to Replace AC .. but if you are moving to new place you need to notice the Size of the room or place where you will going to place. I think size does matter if you moving our self to big place from Small. its cause low cooling..
