I've done some searching in the forums and found one topic that was following my question, but never seemed to come to any definite conclusion. We had some pricing issues with our local York distributor and moved over to Westinghouse (Nordyne) as our primary line for about 2 years (08ish to early 2010). In that time, we installed hundreds of Westinghouse HPs and A/C's for our customers. Since then, we have had to go back to replace evap coils in a good 60+% of those systems - sometimes more than once. The timeframe on the leaks showing up varies, but it seems they are inevitable. In the beginning, we did what we could to convey no charge to the customer for the replacement - but after a while, it was just hurting our bottom-line too much to keep doing this, when we were getting no recourse from the Distributor or Nordyne. Now we have a lot of ticked off customers who don't understand why they have to pay us to replace a coil on a system that's 2 years old. There was some mention of a possible recall or notice released from Nordyne regarding the issue in the previous thread. It seems it was around the beginning of this year Nordyne came out with their new replacement coils, which are completely redisigned - and they are taking the formicary corrosion is the only culprit route. I'm not 100% discounting that it is a contributing factor - don't get me wrong, I understand that it is a growing concern. My problem is that the York units we have installed in the years prior to our switch to Westinghouse, some that we installed while we were also installing Westinghouse, and the hundreds we have installed since moving back to York - this has not been an issue. Yes, there is the occasional leaker a year or 2 after install - but I'd put it closer to the 3-5% mark, than the HUGE percentage we have seen with the Westinghouse/Nordyne. If formicary corrosion was the culprit, it should be presenting the same problem regardless of the brand of unit. It seems to me that Nordyne determined that they had a manufacturing defect and redesigned the coils
Has anyone had a similar experience, and if so - have you heard anything from your distributor or Nordyne about a recall or compensation for the homeowners that are getting hammered by this? Our local distributor has essentially said there is nothing that can be done, and they have heard of no recall from Nordyne. York had a similar problem several years ago with their "blue coils", but they (or maybe our York distributor) went above and beyond to assist with those replacements - we got the part (with markup), labor, refrigerant and travel for all of those replacements - even when they were well outside of the manufacturer's DOA/30 days labor.
