Just a quick question on a new home and the first real time we have fired up the Central A/C -
Noticed on the high-side supply line to the basement AHU that I can hear a strange noise every so often that sounds like air in the line. If you are touching the line during the event you can "feel" something like water in a garden hose type of thing. Really hard to describe. The system is working fine with no complaints, again, just curious if this is something I should have looked at.
Question #2 -
Attic AHU is set on the lowest fan speed. I believe this may have been done because I was very addiment I didn't want to hear any blowers in my bedroom(s). It's on it's own zone and is only for the 2nd floor. (It's own AHU and Condenser). Any possible problem switching from low to medium fan speed?
Any feedback would be great. I'm really concerned about that strange noise on the head line.
