Preventive maintenance


I would try it on a SMALL out of sight area in case it does eat paint.

I might try it on a spot that isn't visable.

Then if no harm, use it on the rest of the coil.

Foaminator or Total Line condenser cleaner.

Man! The Total line is half the cost of Foaminator and works better.

I use ACE foam & clean. It will take the paint off if I mix too strong

I tested Greased Lightning on an inconspicuos area and no harm was done. I proceeded to spray the outer side of the condenser coil through the equipment louvers and allowed for a 10 minute soaking. I then removed the fan assembly and spayed a garden hose on the shower setting from the inside out, from top to bottom, for about 30 minutes. Being careful to insure that the fins would not be bent while spraying. It seemed to clean the condenser coil adequately. I must say that cleaning the evaporator and condenser coils has improved overall comfort from the heat pump.

Way to Go!! A clean unit is a happy unit and saves $$. I would now get the freon level checked as part of a normal checkup. Your operating pressures may have dropped as the coils are cleaner and if you are a bit low on freon that will show up now. Low freon level costs LOTS more in electricity to run.

Preventive maintenance


Just spent all day on a condenser. thought i'd clean it because I've allowed mulch to wash away, & now mud splatters into the coils. baked-on. Used a non-acid coil cleaner per instructions... (should have diluted about ten times the recommended!) Paint (which I did not know about) started lifting out of the coils when sprayed with water from the backside. Made a plastic-like coating on the outside of the fins! Went back with a stronger mix to get the stuff out (flowed water though the backside and used a haircomb to ease the strands out from between fins. Back-breaking & time-consuming. What did I do wrong? Water alone was not getting the mud out.

Installed a new package unit last year, six mos latter burned compresser, replaced. Lasted till may, replaced another compresser. Lasted two days. Called manfucture they sent a new unit, lasted about three weeks. Manfucture is sending a rep out. Just wanting if you guys have ever had this problem and what the fix was.

Thanks for your advice

Check for voltage problems.

If its 3 phase. Put a phase monitor on it.

A lot of commercial units lose compressors due to brown outs.

Most acid cleaners will do that. Unless you dilute them a lot more then the instructions say.

Con-coil works the bestJMO. Con-Coil™ is an acid based foaming brightener and cleaner for finned, air-cooled condenser coils. It's penetrating, surfactant aided, foaming action lifts obstructing contaminants such as bugs, cotton-wood, grass, lint, dirt and oxides from coils. Con-Coil™ can also be used for cleaning electronic air filters.
