The X-13 carrier, (ICP), uses is trash. I change 3 a week and have been ever sense they switched over to them years ago. I love them for the business they’ve brought me but carrier lost my business on account of it and I’m sure many others. Explaining why a brand new system is breaking down to my customers is awkward, explaining why the replacement for the x-13 crapped out as well is even more awkward. The x-13 is trash. I’m just curious why the breakdowns are happening? Is it too low of static pressure due to duct systems being so over sized? Everybody at the distributor blames it on the Taiwan kids letting moisture get in the electronics before sealing it up but what do them sales men know about electronics!
