May 05, 2008· If the copper and aluminum are both 3/8", Trane makes a coupling designed for just this repair. It crimps the aluminum on one side and the copper on the other. You can get it at a Trane parts store for sure, though others may sell it as well.

If the problem is where the copper tubing goes into an aluminum header piece on the coil, sometimes there is enough brass or copper stickout to brazeon a new fitting there, sometimes it is a threaded fitting which can be removed and replaced, and there are also mechanical flare-type repair kits from Trane and others for that - to essentially

The US CPSC has recommended only re-wiring or use of the AMP TYCO COPALUM connector and the "copper pigtailing" repair approach using the AlumiConn™ for aluminum wiring, The AlumiConn™ is a more-recent aluminum repair product which appears to perform well in this application and is now also recommended by the US CPSC.

Aluminum wiring is sometimes found in older houses, and people often become anxious about connecting it with copper wiring in extensions, unsure of whether it is safe or efficient to do so. They are actually correct to be worried about this, as the uniting of the two metals can cause a chemical reaction called electrolysis, which may lead to

Another compliant option is the King AlumiConn, which can connect both aluminum to copper and aluminum to aluminum. These require a precise torquing of the screw connectors. Depending on the wire going to your light, you might have to pigtail copper to aluminum in the above manner and then wirenut the new copper to the light.

Ignoring expensive crimpers, Ideal Twister Al/Cu (purple) wirenuts are NEC compliant. (Your jurisdiction might vary.)

The problem with the technology back then was the connection point to the copper line set. They used a compression type connection to connect the line set to the evaporator coil. After some time this connection would leak. With no real way to repair this leak, the solution was to replace the coil with a copper tube and aluminum fin coil.

If the problem is where the copper tubing goes into an aluminum header piece on the coil, sometimes there is enough brass or copper stickout to brazeon a new fitting there, sometimes it is a threaded fitting which can be removed and replaced, and there are also mechanical flare-type repair kits from Trane and others for that - to essentially


If coil replacement becomes necessa ry, application of the supplied aluminum splatter shield to the header is required when brazing the replacement coil's copper to copper connections. This prevents the possibility of galvanic corrosion created by braze splatter interacting with the aluminum coil. Figure 3. Double Microchannel coil with manifold

Perform a leak test and repair as necessary. Tip. Moving the copper defrost bulb away from the bends on the evaporator coil will often reveal hard to find leaks. Warning. Do not attempt to solder a refrigerator's evaporator coil. The aluminum coil has thin walls and will melt with extreme heat. references & resources

Jul 15, 2015· Stop using copper to manufacture cooling coils. The photos above show copper and aluminum coil tube walls subjected to a formic acid corrosion test. Trane has found that aluminum is not susceptible to formicary corrosion. Through great feats of science and manufacturing genius, Trane began production of an all-aluminum air conditioning coil in

King Innovation's AlumiConn Aluminum to Copper Lug is approved by the Consumer Product Safety Commission (CPSC) and numerous insurance companies as a safe method for aluminum wiring repair. AlumiConn is a lug style connector with three separate ports to eliminate intermixing of conductors.


Jan 14, 2011· The compression fitting work pretty good, Carrier used to have a kit to fix the first aluminum coild they came out with in the 70's, on theirs, they sent a "spinning" tool that you put in a drill motor and turned the aluminum down to the proper size, that caused allot of people problems because they didn't read the directions, to oil the hell out of it while you were spinning

Copper Gutters 101 Copper gutters lend much to the aesthetic appeal of homes, especially Victorian and Tudor-style homes. However, it can be difficult to sort through all the various options since copper gutters come in so many different shapes, profiles, and thicknesses.

Aluminum Wiring. Fix the problem. Completely rewiring your home isn’t practical in most situations—it means tearing into walls and ceilings. But an electrician can make the connections safe by adding a short section of copper wire to the end of each aluminum wire.That way, copper rather than aluminum will be connected to each switch, outlet or other device.

Does spending more money for copper lugs offer extra security and reduced maintenance? During the early 1960s, the electrical industry began installing aluminum wire in many locations, and wire termination failures were commonplace. Installers used aluminum wire lugs (today called "terminators") on almost all wire terminations, knowing little about the thermal properties of aluminum.
