2 Pieces Different Fin Comb Condenser Fin Straightener Air Condition FCR6 Fin Comb and Stainless Steel Fin Comb Radiator Repair Tool Set for Straighten Evaporator Condenser Coils

Worked as intended for

The plastic combs didn’t work on my window units, but the metal comb did work.

Some tenants of mine apparently used a baseball bat against the condenser unit. Imagine their shock when the air conditioner stopped working very well. You can't fix stupid.What you can fix, are those thin little strips of aluminum that act as the heat sinks on your condenser. These tools do just that. They straighten the little strips of aluminum so that air can once again pass through them, and they can discharge excess heat into the air that the fan passes through them. To be honest, the fins have to be pretty darn bent up before it makes much of a difference, but it will make a difference. If the difference is too small to be perceptible you can rest assured that even the smallest little bit will eventually show up in your energy bills. These tools will pay for themselves over time used properly. Easy does it, don't make matters worse, gently lift the fins back into place with these combs.

I've got a couple of GE window AC units as a home backup in Houston. Usual bumps into the condenser fins. None of the plastic combs fit being too wide. The metal tines on the other piece would not neatly fit in between the fins and mostly just crumpled them. I don't think it was me.

This worked perfect to straighten my coils. They kept freezing and I got this to see if it would help it did. I would recommend

Takes way to long to get all 20 plastic teeth in between the aluminum strips, and when you do they just pop right out as you go to slide it through a dented area. Also the stainless steel one fell apart completely after trying it one time, all the teeth just started falling out one at a time starting on one side.

I was hoping to use this for a couple automotive condensors that have seen a lot of miles and have multiple fins bent in. Unofrtunetly the automotive style fins are in a v-shape pattern across the condensor. Unfortenty these would not work for this style. had to use a small screw driver and a few hours of work to straighten out.

Worked great on my AC unit when I was cleaning it before I turned it on.
