if they found it with their scope that sounds more like a drain pan leak not refrigerant. a lot of drain pans will come off and can be replaced with out replacing the coil. I jb welded one once
Until the electric bill arrives!
After thinking about this, what saddlebum says makes sense. The refrigerant would have to actually be spewing out the leak at the time they were looking at it with the scope otherwise there would be no evidence of a leak unless it was an obvious visible hole. It would not remain in a liquid form. If the system is still cooling, I don't think you have an A coil leak.
Dang, you gotta be roasting. Lol. I keep mine at 67.
Me too. 67 to 68.
When the unit is running the A coil will frost over from the humidity in the air that freezes out. When the unit shuts off. The frost melts and the water drips into the catch pan and funneled into a drainpipe. If they are seeing mold it is because a section of the tubing is never completely drying out between cycles. I am no mold expert so what species it is is beyond me. It could be benign or a serious health issue. Mold on the coils is not normal in my opinion. I would consult with a H&A expert and ask them what might be causing this. It might just need a good cleaning.
Yes they can, but it is usually because of using cheap filters that let too much particulate matter through. Some of it sticks on your duct walls and some will accumulate on the A coil. Once that starts to build up and stays wet then mold will grow.
