fresh air intake
Hello;
Just had a new Goodman air cond/furnace unit put into my home. The contractors cut the existing fresh air intake PVC pipe that used to be connected directly to the old unit, and left it open about 2' from the furnace room ceiling. The pipe has no screen on it anywhere. Obviously I know nothing about this stuff, but here are my questions anyway ... 1) Does this installation sound like it's to code? (I live in OH.) 2) From Googling, I've seen that some people recommend that the fresh air intake duct should discharge no more than one foot from the floor. Is this true, and if so, why? 3) I've also seen recommendations for putting a couple of 90 degree elbows on the pipe to form a U shape, like a sink trap, to help buffer air coming in (U shape holds denser cold air). 4) Should I just put a coarse screen over the pipe on the outside of the house to keep bugs out etc., or is something else recommended? Thanks for helping out a novice. |
