how long does an ac unit usually last

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

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.” 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.

We’ve all wondered this at some point, usually after coming home to a stifling house on a long, hot, summer day—do you really save energy by shutting off your air conditioner when you’re gone for the day, or is it better to just let it run at the same temperature setting all day long? Wasting energy not only costs you more money, it leads to more burning of coal and other fossil fuels that contribute to global climate change. We contacted Jennifer Thorne Amann, MES, buildings program director for the American Council for an Energy-Efficient Economy (ACEEE), to help us figure it out. You may unsubscribe at any time.

While it may seem like your unit has to work hard to cool a space down from 80 to 75 degrees, “air-conditioning systems run most efficiently when they’re running at full speed,” rather than running for shorter periods at a less powerful speed to maintain a constant temperature all day, Amman says.

They’re also better able to dehumidify your house when they run at full blast, she adds. If you have central air, or a window unit with a thermostat, you can save energy and keep things from getting unbearably torrid by setting the thermostat higher. ACEEE estimates that air conditioners use three to five percent less energy for every degree you raise the thermostat. To get the best energy savings, leave your thermostat set at 78 degrees or higher while you’re out.

Whether you turn your central air off or turn its thermostat up when you’re out of the house, a programmable thermostat can crank up the cool factor before you get home. That way your house will be comfortable when you walk in the door. Amann notes that you’ll need to buy a thermostat that suits both your cooling and your heating systems.

Some models don’t work with heat pumps, which can pose a problem in the winter, so check with whoever installed or services your system. If you use a window unit, an appliance timer can serve a similar purpose and newer models may include a timer as well as a thermostat. Buy a ceiling fan. Fans don’t necessarily cool a room, but they move air across your skin, making you feel comfortable at a higher temperature. That allows you to set the thermostat higher and stay cool while using less energy. However, because it doesn’t reduce the temperature of a room, it’s a waste of energy to leave a ceiling fan on in the hopes that it will keep your house cooler while you’re gone.Large, shady bushes planted on the south and west sides of your house will reduce heat gain during the day.The easiest way to cool a house is to open a window, but not too much. The less you open it, the more of a draft you’ll create, and it can also be a great natural air freshener by filling your home with pleasant fresh air.
