Hello,
I have completed assembly of a DIY glycol chiller made with a widow A/C unit and a cooler. My question is in regards to cleaning condenser coil. It is a used unit and has some dust and stuff in the coils. Just curious what methods people have used to get them clean before adding glycol to the reservoir.
Thanks.
I have used compressed air, a vacuum, chemicals, water, brush, fin comb and compressed CO2 depending on the size of the coil, the extent of dirt, the proximity of the coil as it relates to its environment, etc. I would typically remove the casing from a window unit and blow compressed air from the fan side through the shroud.
