Rheem Air Conditioner Units Sold With Defective Coils, Leaking Reported Rheem Manufacturing, a leader in the air conditioning manufacturing and sales industry, is selling air conditioning units to consumers with the expectation that the air conditioners will operate appropriately and will last for years. Customers, instead, report being sold central air conditioner units that have been constructed with defective, leaking evaporator coils. What’s more, according to a number of reports, Rheem does not appear to be honoring its warranty. Our firm is investigating claims for a Class Action Lawsuit against Rheem Manufacturing for selling air conditioning units constructed with defective evaporator coils. AC Coils Leak, Warranty Not Honored Rheem evaporator coils are reportedly leaking just after the unit has been installed, in many cases. When these leaks occur within the warranty period, Rheem has the option of replacing the defective coils. Instead, according to reports, Rheem has only been offering replacement costs for parts, not labor.

Should the customer discover the leak following expiration of the relatively short warranty period, consumers are expected to pay for replacement coils and labor, which may total about $2,000, despite that Rheem appears to be aware of the issue with their coils. Science Backs Copper Coil Corrosion Theories Experts explain that the corrosion seen in some Rheem air conditioner models causes the coils to leak. A prevailing theory is that contaminants in the air cause the corrosion, which occurs on indoor coils during the cooling cycle. The contaminants apparently become acidic when exposed to moisture, which causes etching on the coils, a phenomenon known as “Ant-Nest Corrosion” because the etching appears similar to ant nest activity. This corrosion thins the coils, eventually making the coils porous and very prone to leaking. The coil’s copper surface “will be discolored adjacent to the corrosion pit(s). Surface films can vary from dull gray-black to red-brown or purple, depending upon the specific environment,” Peter Elliot of Corrosion Materials Consultancy Inc., and Richard A. Corbett of Corrosion Testing Laboratories wrote in a paper on the matter, according to an ABC News report.

“The corrosion initiates from the tube surface and progresses rapidly into the tube wall,” they explained. The damage progresses rapidly; “Perforation usually occurs in weeks or months, not years.” Researchers writing in Metal Madrid, report that the defect causes “the loss of refrigerant liquid and the consequent environment pollution. It is known that attack requires the simultaneous presence of moisture, oxygen, and a corrodent, usually an organic acid … or other volatile organic substances.” In fact, note the team, some 10 percent “of all premature failures of copper tubes used in the heating, ventilation, and air-conditioning (HVAC) industry are the result of ant-nest corrosion” and “usually occurs in thin-wall copper pipes, especially when copper is de-sulphurized. The paper authored by Elliot and Corbett provided the same explanation that, “Any nest corrosion will only occur when oxygen, moisture, and a specific corrodent, usually an organic acid, are simultaneously present on a copper surface.

The damage is worse when stagnant fluids are retained against the copper surface, or when crevices are part of the unit design.”small outdoor ac unit Although the cause of the coil corrosion appears to be well understood and scientifically backed, Rheem continues to sell air conditioning units that suffer from this flaw and refuses to compensate consumers appropriately.best window ac unit 2014 Help for Owners of Rheem Air Conditioning Unitssizing ac unit for home We are available to help anyone who is in possession of a Rheem central air conditioning system.

Tesla is working on it CC BY-NC 3.0 Tesla There were many interesting bits of info that came out of Tesla's last quarterly earnings, and we mentioned many in this article. There was one thing that didn't make the cut at the time, but is still quite interesting, especially for those of us who like to keep vehicles for a long time but hate mechanical problems. Elon Musk mentioned that Tesla has changed its target endurance for its drive units (the part that hosts the electric motor, or motors on the dual-motor models).Tesla/Screen captureUp to now, they were aiming for 200,000 miles, which isn't bad. But the new goal is a lot more ambitious, and if achieved, will show another way in which electric vehicles are superior to gasolines ones; there's a lot less mechanical complexity, fewer moving parts and fluids sloshing around, and fewer things that can go wrong.

Here's Musk on the conference call:We are very happy with the quality of the drive unit. We changed the goal of the drive unit endurance from being approximately 200,000 miles to being a million miles – just basically we want drive units that just never wear out. I think we made really good progress in that direction. the drive unit that are going out now and for the last several months have been excellent.Tesla/Promo imageMusk admitted to problems with drive units in the past, but claims that these have been fixed now, and that any problems would be covered anyway by the 'infinite mile warranty' (for 8 years) launched last year. Here's what he wrote at the time:The Tesla Model S drive unit warranty has been increased to match that of the battery pack. That means the 85 kWh Model S, our most popular model by far, now has an 8 year, infinite mile warranty on both the battery pack and drive unit. There is also no limit on the number of owners during the warranty period.Moreover, the warranty extension will apply retroactively to all Model S vehicles ever produced.
