Cleaning Heat Exchanger
« on: September 12, 2022, 06:48:12 PM »

I'm wondering would it be safe to use a light coil cleaner similar to what I use for evaporator coils in AC servicing?  I have kept the filters clean since I reinstalled here where I'm located now. I had it located in the breech of the return duct and it was fairly dusty at out other location. The actual coil is not really seriously dirty but I've never cleaned it and I'm getting started servicing things for winter as I have time. Air handler today and boiler maybe next week if it's not monsoonal again!  I have used this Viper evaporator cleaner on a lot of occasions with no trouble and just wondering if anyone else had tried this approach. My wife considers me OCD but I just considering it doing the whole job,no short cuts LOL  Even on my own system LOL

Just to clarify this is for the outside of the exchanger,white vinegar makes a great back flush agent :)

Thanks Guys

I can report back that this works excellent!  I couldn't really see where mine was that dirty but after foaming it up and letting it set there was all kinds of brown foam coming from it. It did increase my air supply a little and that was greatly appreciated. Maybe not part of the yearly start up service but ever couple of years it seems it would make a difference.
