My townhome community is less than five years old, there have been 3 Carrier air conditioning explosion in that time frame all 38CKC models. The most recent one was one door down from my home on Wed July 2, 2008. Both Units exploded, and caught the back of the house on fire within minutes. We had a HOA meeting 2 days ago and they seem to think that there is no need there is not a problem, its all just a fluke. But after the first explosion in 2006 at a different home in a different row, they built the remained of the town homes in the community with bigger units. I guess i am looking for any help I can get, does this sound like and installation issues? a batch of bad units our wonderful builder my have gotten a deal on? or just bad luck? Any insight would be greatly appreciated. The Hoa said we are on our own if we want to have our units inspected and we are not even sure what we should be looking for? Please help.....................................
