This video will show you a very simple way to clean the condensate drain on your air conditioner. IMPORTANT: BE SURE TO USE A VACUUM CLEANER THAT SPECIFIES THAT IT’S A WET/DRY VACUUM CLEANER.

Thanks. It could save you a lot of headaches.
Just bought a Carrier Infinity a/c unit 2 months ago and today/last night it kept shutting off and we heard water dripping. Checked the condensate drain and it was not running. Saw your video, hooked up the shop vac, and within a minute the unit was running again. Thanks!!!
Thanks for watching.
Dr Z buff an run LOL
I am suffering now from a clog condensation tube. The water damage from my unit caused a leak in the ceiling of the condo unit below and mold developed.
I used to work at a ten story hi rise condo on Fort Myers Beach. It always became a finger pointing contest when someone’s condensate drain plugged up and caused water damage to the units below. I’m sorry that you didn’t see this video sooner.
I had an inspection done on my 10yr new A/C where the technician quoted that the
“condensate drain was removed & coil drain pan broke. Pan or complete coil needs to be replaced.”
He quoted Pan & Drain $950/-
Coil & Drain $1050/-.
What is your opinion and how can I do something to minimize the expense by fixing it myself please ?
You might as well take the coil and drain option as long as it comes with some sort of warranty.
Very helpful! We have some minor water damage on our ceiling, which we assumed was from a clogged dryer vent condensing. Turns out we still have dripping water and our AC cut out. Where might our condensing valve be in a two story condo? Thanks for this video!!!!
I have a much larger diameter vacume hose. To reduce it to 3/4 pvc size, I cut off he top part of a water bottle or soda bottle. I put the part of the bottle you drink from on the PVC and the vac hose inside of the bottle from the cut side.
This makes a good inverted funnel and allows me to use a higher power vac.
What do you think of pouring white vinegar in the condensate line at the air handler? What do you use?
I don’t pour anything down the condensate drain. I’ll usually put tablets in the condensate pan to keep the funk from growing. Then I’ll vacuum the drain at least once per year.
You’ll probably have to cut into the condensate drain near your air handler to perform this preventive maintenance.
all your post r very helpfull….thanks
Thanks for watching.
That filter drier should be inside @ the evap coil. Could rust and cause leak..
you would of loved the drain i saw on one unit. it was a horizontal in a crawler, and they ran the drain line in the ports for a vertical set up. water stain all over. and the humidifier drain tube ran down, flat on the dirt, then up hill to the pump.
Your refrigerant and condensate lines are buried in the ground? Or am I just seeing things? If so, have you ever had a corrosion problem with the copper being buried like that?
Yes, my line set and condensate drain is under ground. I haven’t had any corrosion problem yet. However, I do plan to soon replace my line set when I replace my air conditioner. I’ll run the new one above ground.
Sounds like fun. lol
I do prefer them inside whenever possible. I think that I’ll put the new one inside when I replace my air conditioner.
What about blowing out the guk with CO2 cartridges? Since many drains tie into a household drain going into a sewer.
Condensate drains in Florida normally drain outside. Draining condensate into the sewer is not to building code in most counties.
That could be why people in FL often find garden snakes and other lizards in their houses, it’s a good way for them to enter.
Yeah, lizards mostly.
oh this NEVER worked fot me so guys dont wast your time!
