I've looked around the website, but couldn't find an answer, so I'm posting this as a new item.
I'm just a guy who had a system installed. So, the answer to my question may seem obvious. But, I'm looking for one!!
There are 2 condensate lines coming out of the coil. My understanding is that one is the "regular" line, the other an "overflow" in case the "regular" one plugs up. Yhe "regular" one has a trap and runs to the outside of the house. The overflow comes out of the coil and does a 90 to point down to the cement garage floor.
My question : should I be feeling air blowing out of the end of each line? And, if air should be blowing out, how do you eliminate the whistle-like sound coming from the overflow line?
Thanks in advance.
