Florida AC drain monthly maintenance and How to unclog

Part 2 and 3 links shown down below in description explain how to unclog.
This video is intended to help new Florida (SW and Central) DR Horton owners understand the quirks of clogged drain lines and the monthly maintenance we can perform to prevent the clogs. Please for the love of Pete, don't feel the need to comment about the missing trap or I'm calling the evaporator the condenser. This was setup by DR Horton for the SW Florida region and the whole drain line is a trap. I'm just the home owner sharing the best I can, but my main point is not not use corrosive material when the drain is already blocked or it will work it's way back into the unit where I'm pointing with my finger. Always seek out HVAC experts which I'm clearly not. But hopefully if your AC is out and you are in a bind, this info can help you determine if you have a clog in the drain and point you in right direction to remove clog and get your AC back on-line.
If you are trying to clear out a clogged drain, make sure to following:

Trane air handler 2nd floor attic, when algae gets in the pvc drain line,I simply give the p-trap a short blast of water from the hose outside which forces water upwards and the weight of the water forces the pipe to clear itself.

My central ac line doesn’t have a p trap or access spot on the line. wtf. Who installs these things? My drain line goes out to the gutter and drains in that. I have no way of getting a vaccum on the end of the drain ljne. Not climbing to the second story of the house. I think these ac companies install these without clean outs on purpose.

My drain pan stays filled with water. I pour water and vinegar down the drain line and goes outside fine. Over all AC works gine and cools the house. I do i clean the very beginning of the 2 drain lines? One with the switch and one without

[@SuperVstech]

A little hint, it is a good idea to have the trap as close as possible to the unit, with the clean out directly above the trap, so a brush can clean out the trap debris.

My issues reversed, no idea what to do. My main line clogged a few days ago, I did what I always to, stick my finger in the drain hole and snake a straw from a compressed air can into that hole. Clogged cleared! However the other line is now clogged, which should only occur if the main is backed up, which it's not....so wtf is going on here lol

I was told to put 4 cups of bleach followed by 4 cups of hot water.

Also, that sensor should be right out of the coil tray drain, not with a sloping pipe that can accidentally be pushed down to lower than the tray bottom.

After you shop vac the pipe outside to remove the water, should the system turn back on by itself? It’s not for me and I even turned the circuit breaker on and off. Pretty sure that’s what the HVAC guy did last time??

[@rpmfx1000]

And the auto vent?

[@rpmfx1000]

Where is the p trap??

[@rpmfx1000]

You’ll can end up sucking water back to the tray from the p trap if your fan is pulling the correct CFM . That drain will always be at negative pressure, that’s why you need a vent just after the p trap.

What air filters are you using and how often are you changing? I have a DR home and am starting to get into my normal AC cleaning groove and wanted to know what you had experience with.

thank you!!

Well finally, a unit that looks a lot more like mine. I have a TRANE. It's rather newish. It's clogged. My mini shop vac sucked about a teaspoon of grey slimey gunk from the dip line outside, but that was all. Still no AC. I checked the overflow unit. Maybe a couple of drops of water was in it. The floaty wasn't in the up position.

I have a new home in St. Augustine, but don't live there full time. The best I can do is perform this maintenance every 2, sometimes every 3 months. Will I expect issues down the road with that interval?

[@ChristineLV]

I was told no never use bleach if the drain is slowing because it will cause corrosion. My a/c drains outside. If it isn't backed up, does it matter?

[@karenpalermo2030]

My drain goes to a weep space .Is it ok to still use the vinager in the drain?.

[@Mysteryp7]

That right one is headed upper and(white clog?) mine pops 💦 water out… should i block it? Or how to fix it? Thanks

[@samueljames9342]

Why would you angle it down any? That would cause it to hold water until it could evaporate. I would think it should be perfectly level.

[@jantravia6984]

Can you tell me which drain pipe goes to the outside? Would it be going into a silver foil wall then to the outside? Thank you! ❤️
