Cooling fins damaged...

[Joe Funderburk, CMI]

...probably by Duke. Would you refer this to a HVAC tech? What would he say about it? If the AC is otherwise cooling satisfactorily, just wondering if a referral is the proper thing to do.

I would mention it, And refer it to a ac tech if you dont it will come back and bite you worst than dog giving it the golden shower. Home warranty tech HMM ( home inspector should have reported that. Coils are designed to work even if some are flatten but that is corrision which will lead to a leak down the road.

I have always simply explained that the coils were damaged, that it may lead to leakage and plan for replacement because of the potential for leakage.

[Joe Funderburk, CMI]

Thanks. I've always referred it too. Just questioned myself.

Can someone tell me the reason for this deterioration? This is a townhome complex. Three of the units that I noticed looked just like this one. They can't all be due to dog urine, which was my initial thought.

[Bruce A. King]

The landscapers may have sprayed liquid fertilizer on them.

[Wayne B. Wilson]

Well it may be what Bruce said , ut my money is on a dog marking his teriotory .Homes close to each other?

Mulch could have been piled up too. I watch a dog do 2 units on a inspection LOL wouldnt be nice to run a capitistor wire around the frame

I sent photos to an HVAC friend of mine. Here's his reply:

"Its normally caused by dog urine, it hurts the heat transfer which kills efficiency, it can cause refrigerant leaks. should be checked."
