I have an issue with an A-coil it took a little over a year for the Freon to empty out. it was determined that their is a pinhole. I have had 2 HVAC companies come and look, both want to replace the A-coil. The whole system is just over 1 yr old. My question is can I put in a coolant sealer in the line the same as what they put in cars in the home AC line? No one will answer the question here. I only get its "too hard to solder the aluminum" when I start asking about putting nitrogen gas in the line before soldering.
Of course both HVAC companies want to replace the coil- they see big $$$! It's always amazing to me, and a little sad, that some service companies don't have the integrity/decency to offer an inexpensive & easy fix for something like this.
To answer your question, yes, you can use a sealer, and they are especially effective for a pinhole leak. One product in particular, if you want to research it, is Easy Seal by Nu-Calgon. It has a chemical reaction to oxygen so when it reaches the leak it permanently seals the hole.
Lastly, if the system is only 1 year old, it should still be under warranty, and you could have the cost covered by the manufacturer.
I ordered it from HVACDirect. com and because I put it in myself and I'm a lic. contractor they will not honor the warranty... I searched around on amazon for a while and going to try the this "Leak Saver Direct Inject Ultimate 3-in-1".
Living in a little town it is become more increasingly difficult to find anyone that can do anything other than "install new".
