You know the drill. Coils need maintenance and regular scheduled cleaning to maintain solid air flow and system efficiency. So, what’s the right tool to clean them with? Well, there’s a lot of options to do it. We recommend the CoilJet Portable Coil Cleaning System from SpeedClean every time(disclosure: it’s our product!), but one thing we won’t ever recommend. A power washer.
Pictures tell a thousand words. Power washers push out thousands of PSI of water pressure. Fantastic for blasting and cleaning a huge variety of things, condenser coils is not one of them!

See the lovely abstract artwork. Airflow now is at about 5%
This is what can happen when a power washer is used for cleaning AC coils. The water pressure can cause immediate, instantaneous damage to sensitive fins. Bending, rupturing – even blasting holes right through them. The end result? A ruined coil bed that needs replacement. Lost time, lost efficiency.
So, whatever you try, even if it’s not a one of our products, step back from the power washer. It’ll cost you more than you’d like to know.
