We had a carrier infinity system put in place 2 years ago. A week a go we had a system failure and notification on our screen for system malfunction. It turns out that the damper control module failed...
if your air handler and ductwork are sweating, this tells me that the unit is operating too cold. The slower the airflow, the colder the temp. Your infinity unit is a wonderful machine! But I've seen many of these units that horizontal leak water due to airflow issues. The air handler(inside unit) has a true "variable speed" blower motor. Where we used to have low, med., high speed, now an 1100 rpm motor will have 1100 speeds(so to speak). Now after installation, the company should have sent the technician to set the system up by checking a TESP, total external static pressure. This info is located on the air handlers info on the front of the unit(sticker on panel). This verifies that the airflow is adequate and proper for your house and ductwork. If this is not right then blower motor damage may occur. Also, if you can imagine a cold can sitting on the table. If the temp in the air is warm and moist the cold can is cooler that the air it is sitting in. The can will sweat and a puddle will form on your table. Now, your air handler is running too cold, probably due to low air flow. Its sitting in a warm(er) moist environment, and sweats. It's all insulated but this won't matter due to infiltration of warm air through the insulation. Most people don't understand why too cold is a problem in cooling but this is one problem we have. And also, this unit may be leaking water from the condensate pan. I've had issues with this style. If it's not draining properly, the pan holds water and that water is pushed out of the pan by the blower. If the unit is not level, or down hill just a bit, towards the drain outlet, it will hold more water in the pan than its designed to hold. It also has a zoned damper? These zoned contrlloer/damper control modules can be installed anywhere, not just a closet. It would help if it's in a controlled environment, but not necessary if the machine is set up properly. I'm 99% certain you have an airflow issue! Get a second, third, fourth opinion. It may/will take more than 1 trip to fix this. Carrier corp. has dealers that sell/install Carrier machines. These companies have experience (ask them up front) with the infinity. And also have Carrier tech support. Ask for a TESP check before you schedule a service call. And any qualified tech won't mind explaining this process as you look over their shoulder as the work. You'll also been to get the duct reinsulated. I would contact your installer and ask them to rectify this issue, at their cost. Your contract with them should state a warranty, and also a "time subject for repair" if problems arise. If you are not satisfied with their answer, call your local/state license authorities. City inspection may/should work if you're inside city limits. Carrier also has field techs! But cost about twice as much as you're used to. Hope this helps!
