Hi there! I live in Orlando in a home where the HVAC is in an outdoor "room". People have been having allergies and I have been noticing a mildewy smell from the vents. An HVAC guy came out and cut out part of the duct box ( see image attachment where the arrow is pointing) and it was coated in mold. He said although it is a more normal thing since we are in a humid climate and the HVAC system is outside, he recommends taking out the first 15 feet of duct and installing an air scrubber. What do you all think of this suggestion? Is there a better, easier fix/ is a air scrubber necessary? Is this something we could handle ourselves? I'm alarmed that this is happening and I don't want it to happen again. Would love to hear your guys' opinions and anecdotes! Thank you!! [attach]108517[/attach]

i have a compressor unit outside and a coil unit in my attic. Had the AC serviced last year and don’t really use it a lot. I noticed that the attic unit is leaking through the metal cover just recently. I opened the cover and took off a second interior cover. There are two lines that look like drain lines. One is draining into a sink drain in a bathroom. The other isn’t connected to anything and is just open. I put a pan under it, ran the AC and it filled up with water. I’m not AC guy but shouldn’t that be capped off? This is an older unit but I’ve never had problems with it before.
