I tried it with the fins combo below, but it does not work with the big dents. please see pictures attached.

Best left as is... you risk doing more harm than good by attempting to fix something that won't make any difference. I would put some barriers up if it's going to be hit by the mower all the time. A few pieces of rebar driven deep would do.

I agree that the damage doesn't look too bad, but if you are careful with a pocket screwdriver or a butter knife and just try for straightening one fin at a time, it can be fixed.

Fin combs, as you are finding out, don't often work very well.

small deep gashes don't reduce performance really, unless the coil is full of them.

what does is having large sections of flattened fins.

this condenser's fan does not really blow up air. it blows the air more towards the sides. I was informed that it was because the fins are blocked or dirty. I did put a paper on the fins around it and it doesn't suck it up very well. it kind of falls down.

I cleaned it up but it did not make any difference. I did notice that I had some big dents so I was trying to straighten the fins out.

Has the motor been changed? The blades may not be positioned correctly.

The coil looks clean from viewing the picture but that doesn't show much except the surface. You will be able to shine light through it if it's clear... use a strong light late in the evening for the test.

A restricted coil could be causing the air to recycle at the fan output so that flow pattern looks suspicious.

If not much light shines through, you'll have to remove the fan to gain access to the inside face of the coil. Then either blow or direct a water spray through to clear any restrictions. You may need to use some approved detergent to break the crud down so it will come loose but that's not always necessary.

The bent fins comprise less than 10% of the coil area and any effect they have on performance is negligible. I wouldn't mess with them.

user_12345a,

thanks for your input. now, the fan spins correctly and I know the blades are positioned correctly as well.

surferdude2, thanks for your input. I will have to do your suggested tests and revert back.

I can back flush our spine fin condenser with a 90° adapter on a garden hose without removing the fan/motor assembly. Hi volume lo pressure is paramount to avoid damage.
