reviews of new mirco channel coils
Over the past few years i have seen a few manafactures moving there evap coils from copper /aluimiun coils to a newer mirco channel all aliumiun coil .I believe there are using this stlye on some condensing coils also .They look like they have the potenial to be a real PIA to clean .I recently went to help a buddy install a 2.5 ton system and noticed the coil was mirco channel i was not impressed with the no TXV and just a metering orifice and basically no distrubition cap tubes to the evap just a 3/8 copper to aluim adp and then straight into the coil .I guess the cost on these type of coils must be a huge savings compared to the ole standard .I am really wondering how well they perform and if there are any issues with them espically when using a low ambient fan cycling where there could be some coil racking i know it was not a issue with the older carrier ED condensers which had aliumiun coil but of a different type of construction simalar to trane style brushed consenser coils .Any thoughts or opions would be nice to hear.Peace and good luck clammy happy 4th
