I am a retired homeowner and bought a Carrier 19 SEER Infinity air conditioner in April 2008.
Each A/C season [ May through late Oct.] here in the Tampa Bay area of Florida this floor mounted air handler in our enclosed garage CONDENSATES so bad we have to put towels around the bottom to soak up the condensate water.
We have had Carrier engineers in to view take instrument reading on the unit and FOUND THAT IT WAS INSTALLED AND SET UP CORRECTLY. They gave us and the installer the following insulting explanation as to why this unit is condensating:
1. We had installed double pane windows in this home. 2.we installed r-19 blown in insulation in the attic. 3. we installed a solar fan in the roof [at its highest point] and that produced a "cold attic syndrome". Can you believe that? I measured the attic temperature over several days and it reached 110 to 112-degrees F. during the afternoon. That is not a cold attic!
Please note that Progress Energy did two energy audits on this residence and recommended all of these changes! Wow! what a contradiction between these two companies!!!!!! Ridiculous and absurd comments by Carrier.
This is not an installer problem. It is a CARRIER problem producing an air handler that is not properly INSIDE insulated for the Tampa Bay market to keep it from condensating--plain and simple!!!!
Carrier will NOT do anything to resolve this problem and refuses to contact me personally to discuss the problem. Carrier refuses to admit they have a problem with these INFINITY A/C units. Contacting the parent Company United Technologies is non productive. I can only suspect that there is a cover-up of a RECALL and that is why no contact with me is made. Note that I have filed State and Federal complaints about Carrier Infintiy units.
Buyer be aware!!!! If you live in a high humidity, high dew point climate you should make sure the A/C air handler you buy does not condensate on the exterior surface.
We bought this expensive unit to help sell our home and now we have an impediment to a home sell.
Let me close with the admission that this Infinity unit does provide a very comfortable atmosphere within the home but that is not worth the problems we have with the condensation on the air handler.
If you know of anything we may be missing that may help solve this problem, please pass it on to me.
