what is a coil in an ac unit

What is the purpose of the evaporator coil in an air conditioning unit? The evaporator coil is the primary contact point for warm air in a central air conditioning system. The purpose of the evaporator coil is to remove the heat and humidity from the air that is passing over it. What are some tips for troubleshooting a central air conditioning unit? The evaporator coil works by drawing hot air over the coil, which is filled with refrigerant, to cool the air. Once air has passed over the evaporator coil, a fan is used to circulate the cooled air throughout the building. The evaporator coil is located inside the building. Typically, it is located directly above the air handling unit of the furnace. The other half of the central air conditioning unit is located outside. The exterior portion contains the compressor, condenser and cooling fan. A central air conditioning unit circulates refrigerant through a series of condensers and coils to remove heat from the air in a building.
The evaporator coil contains refrigerant, which extracts the heat and humidity from the inside air. how much does a new 4 ton ac unit costThe refrigerant is then circulated to the external unit where the condenser is housed. air conditioning unit without ventThe condenser allows the refrigerant to release the heat and humidity into the outside air. typical ac unit warrantyThe refrigerant is once again cool and ready to be circulated to the interior. An air filter is located above the evaporator coil in an air conditioner, typically in a special slot within the duct system or inside the return grille. What are the parts of a Fedders air conditioning unit? The primary components of a Fedders air conditioning unit consist of an evaporator, compressor, condenser and expansion valve.

The coil, also known as an evaporator coil or an indoor coil, is the unsung hero of any home heating or cooling system. transfer, is one of the most important factors in achieving heating and cooling efficiencies that keep your home comfortable all year long. An evaporator coil is located indoors and is either installed with your furnace or as part of your air handler. Inside the coil, the refrigerant evaporates as it absorbs heat from the indoor air thatThe coil essentially serves as a “heat exchanger,” working with your heating system in the winter and your cooling system THE DIFFERENCE OF A TRANE COMFORT™ COIL Each Trane  is designed to
provide your family with outstanding comfort all year round. we strive to bring you the highest quality and performance through innovative technology and precision engineering. So when you choose the right comfort coil perfectly matched for your Trane system, you can be sure you’ll enjoy the benefits of the best home comfort system Like all of the components in our high-quality home comfort systems, each coil goes through rigorous testing to guarantee the greatest durability and protection against refrigerant leaks. We test each coil with pressurized helium to 325 pounds per square inch. to detect a leak as small as .10 ounces per year. A small amount, we know, but because any leak will lower your system’s efficiency, anyDurability means your home will be comfortable now and for years to come. A dirty indoor coil lowers the efficiency and performance of yourTo keep your system operating at design performance, have your coil cleaned regularly.
Indoor coils are often dirty because they’re usually so difficult to access. But Trane Comfort™ coils are designed to slide out on the integrated rail system for easy cleaning. Because the insulation is encased the cabinet can be wiped down, making the job much easier for your dealer, and a clean coil will yield higher performance and cleaner air in your home. 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.” 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.
