How to install water pump on portable air conditioner 

It would have to be a pretty sturdy table This thing is extremely heavy It takes two people to carry it up the stairs also the hose would have to have a 90° bend going back down which would add turbulence. And yes a dryer vent would be a nice insulator for the hose but so far the second 6-in hose actually has been doing a pretty good job insulating the first one It doesn't get warm at all.

My LG air conditioners and many others do have a little motor inside that flings the water around on the condenser that should help it evaporate but of course if it's really humid the water tends to pile up fast. If you're talking about evaporative coolers they are used a lot in the desert but unfortunately are useless in the Midwest or south where the humidity is very high. Hopefully that answers your question

Yup so I recently built a new platform out of wood (which will be featured in my next video) And then I put it at a slight angle so the water drains into the pump and once the water fills up I run the pump and it will already be primed because these circulation pumps do not like air

@@Alexwarestudios Sure, thank you! I was just wondering how it could be done. I was thinking that probably mine portable AC has some kind of water tank, so If I will put an Pump inside and do some automatic-switch, when the water level is above the pump, it will automatically start and stop. It should not be that hard. I just hope that my AC has some sort of water tank. :) Thank you!

@@tomk1s usually there is some kind of reservoir but I would recommend making it manual because sometimes it will constantly run then it will run dry and burn out the pump. But let me know how it goes!

Correct a lot of these LG's only have an exhaust hose and will use the room air as intake. I am currently looking for a larger intake duct that I can modify and make it easy to remove and put on every season The 1-in hose is just something I had laying around and it does help a bit. The negative pressure has decreased in the room. Once I do modify a much bigger air intake on it I'll probably make a video about it

@@Alexwarestudios I'm curious how low to the floor your doors are to that room. As there is no return air ducts in this house only directly under the air handler on 3 sides one into the living room one into the edge of the entry way and long hallway and the third into the office . The back side has the fireplace butting up against it. This must have been the architects first house. But its 3700sq ft so I cut the doors off to allow some circulation for the central air. I rarely run it as I only pass thru the rest of the house other that the kitchen. I've got a friend from India staying here but he is used to the heat. I finally got him to at least open the windows to his room.

@@davidreynolds4684 They are decently low to the floor with only like a half inch gap My old house was exactly like yours with only three return air ducts but my newer house has one in every room

@@Alexwarestudios in Texas in the mid 60s people started stepping away from swamp coolers and adding central air. They usually took a central area closet or water heater closet and stole a few feet from a pantry or in the case of the house I grew up in there was a huge rectangle waste of space that separated the dining room living and kitchen from the bed rooms had a pantry at one end and coat closet at the other. About 12' wide and 18 to 20' long. Dad stuck a central heating and air unit in the hallway side right outside my bedroom. Gotta hand it to him he had a return grill in the hall. Ran a plenum straight across to the dining room which was the center of the house on the right side. Ran one next to the pantry on the back part of the rectangle and one to the front next to the closet. He installed a sears system that didn't use freon. It was the same design as most RV units. It's basically a bunson burner with ammonia and antifreeze in the lines hit heat the liquid turns to gas and is pumped thru like freon. In the 16 years we lived there we had to put 2 blower units in the air handler. I met the people that bought the house when I was in my 20s when I offered them twice what they paid for it. They passed but we did talk about the ac. They said the fan had gone out. But while diagnosing the man found it strange that there were no freon lines blah blah. He said he changed the fan and left it alone. Several more attempts to buy the house up thru my 30s and the AC was still going strong and the only thing ever done to it is replace the fans and change filters. Why everybody doesn't use that system is beyond me. Dad went thru the house and cut the doors off about 1/2 " throughout the house. The doors would still slam shut when the AC would start so he cut a bit more. We pulled the carpet everywhere but the bedrooms and refinished the hardwood. Finally cut the doors to 13/4 to 2 " off the carpet and the doors quit slamming and ears quit popping. We build a second floor over 1/3 of the ground floor at first we cheated and pulled air from the original unit. It actually handled it fine. We increased the fan speed and closed the vents half way in the bed rooms down stairs. To keep from blowing us away. Eventually we put similar unit upstairs.

@@davidreynolds4684 wow fascinating story I never heard of an air conditioner like that before. although I can see why nobody uses it. ammonia can be very dangerous. it's used a lot in food manufacturing due to its efficient nature and the ability to get vary cold But it's also dangerous for humans. At my old house that was built in 65 It came with an HVAC system in the basement because in the Midwest we have basements in almost every house and in 1992 a r22 system was added from carrier and it's still going strong to this day and at my new house it's also carrier as well
