OP will read this and think he needs to change the filter and put the enzyme in once a year. That isn't even valid advice if you live in Michigan.

If you have one, it’s bad

You need a float switch.

You can buy a hand pump from a hardware store for 20 bucks. They work really well when you have the drip pan in an inconvenient place and don’t want to carry a shop vac full of water through the attic. I emptied my drip pan the other day this way in about 6 pumps and 3 minutes. It was very similar to sex with my wife.

Aside from cleaning the line out so your pan can drain, do you know where the source of the water is coming from?

I was in my attic a few weeks ago and noticed water in my pan. The plastic drain valve had a drip about every 10 seconds. Over 24 hours, those drips would fill the pan enough to start trickling out to exterior. $9 and 5 minutes to change out the drain valve.

Apparently, I didn't have a float switch on mine and it was dripping over and made a spot on my ceiling. Never shut off though. Have a buddy who does A/C work come out, drain it, blew the line and installed a float switch. I think he charged me $80

If you use vinegar and it works, great. I and many others use bleach and it works great. So suck it

Normally, AC condensation runs to your internal household plumbing.

If that stops up, it then runs outside to drip.

If that stops up, it flows out of the unit in the attic and collects in the metal drip pan.

If that fills up, a float switch shuts off the unit and you avoid water coming through the ceiling.

If you don’t have a float switch, have one installed.

If you don’t have an easy way to add vinegar, bleach or Liquid Plumber-not recommended but works, or to apply compressed air through, have one installed.

If you don’t have a spare capacitor for your compressor, go out there, get the numbers off of it and order you a spare off Amazon.

If you don’t have a shop vac to use with your hand on the outside condensation drip, go get one.

Then you should be able to prevent or handle most AC problems.

You say you used your shopvac to remove the water. Why not try to use the suction of the shopvac to help clear the drain line. The only thing in there is usually a buildup of algae from not flushing it regularly with bleach. A good suction on the shopvac just may unclog it.

I'd never get an A/C guy out for something as simple as that and pay $$$$ for him to do something that is not that hard to remedy.

I’ve also used a shop at the bottom of the pipe to suck all the gunk out.

Maybe your husband has not had a chance to explain modern closed loop refrigeration to you yet.

The liquid refrigerant will reach the metering device at the same psi regardless of what the tsat is set too. It will then expand and cool the evaporation coil. Warm moist air will become cool dry air as it heat is exchanged over the coil. The moisture will drip into the pan at a relatively constant rate whose function is only total time on.

Total time on may or may not actually be affected by tstat set point as once maximum delta-t is reached the total run time will not change.

Make your man a sandwich and have it ready when he gets home from the plant today and tell him what you learned.

Ohh and you dont heat hot water.

#metoo

I did discover that I was too lazy to run an extension cord out there so I bought a battery-operated small shop vac.

Same thing happened to me last year I thought the drip pan or line coming out of it was clogged , hvac company I called said I needed a whole new unit… I went back up there to look at it again, put my hand on the drip pan near the tube coming out and the water started rushing out, so long story short the drip pan was not level anymore and was holding water, I used some shims to level it , no problem now.


TLDR… see if the drip pan is level

Was told by an AC guy not to use bleach. The fumes attack the aluminum unless you flush it out multiple times which we all know how lazy people are. He only blows the lines out which he said also clears the line better of any debris like cockroaches in it.
