Hi all.
New to this forum, I appreciate the chance to ask a question.
I had a new A/C system installed March, right before the pandemic crap hit the fan.
Since day one, I noticed a pretty loud (to me) noise emanating from the refrigerant lines coming into the house......sound is like a very noisy florescent light in the winter....a buzzing basically.
Our old system (a 35+ year old 2.5 ton HEIL unit) never made any noise but the installer who did that one used one of those pre-filled line sets and left all sorts of extra line.....so it was all swoopy turns rather than sharp bends....sloppy.
So when the crew installed this new lineset, they took special care to make it nice and neat.....but in the process ended up putting a ceouple/few 90 degree fittings in the set in order to make corners neater etc.....
At the outside unit they did a very sharp turn off the unit to go the right direction into the house....then it neds to go in the house...then bends again inside the house to hug the wall, then as it goes into a corner it bends 90 degrees again............THAT is where I hear the racket......right at that last bend.
The COVID thing has slowed response on everything and this is no different.....the manufacturer eventually told them to try a special line lubricant additive for 48 hours.
That has made no difference.
Are the bends the issue here?
I can post pics and video if that help.
It is a Bryant 2.5 ton unit, brand new matching a-frame.
Thanks for any insight from pros and/or folks who have run into this .
I am trying to add pics but I get the message "this PNG image has the incorrect extension"....my pics are JPGs from my phone....so I am not sure what is going on. And I am unable to add video of the noise til after 7 posts, it says. :(
