I installed the window vent kit for my new Haier 10,000 BTU portable air conditioning unit. The kit that came with the unit leaves massive gaps between window frame and extension panels (issue: air flow, noise). I am wondering if there are better window kits available. I would want it to fit a 42" window, have a single hole for the hose, and fit tightly into the frame so not to leave gaps. Note: using weather seal with the kit that came with the unit is not an option, the plastic panels are thin (actually, they seem made on the cheap - when extended out, the longer of the 2 panels wobbles). Any leads to a better window kit solution would be greatly appreciated. Thanks for your question and welcome to the community! I assume your portable A/C unit is the one shown below, correct? I checked the installation manual and I came up with the vent kit in question, shown below. Since this particular model isn't sold at any of the stores near me here in Atlanta, I haven't had issues with the system.

I have though seen very similar models sold, and we don't carry additional kits in our store. You can call Haier directly from the owner's manual link above on page 12. See if a local authorized service center has additional parts or added know-how that we can't answer here. If it were me personally, I would stick with what you have and give it added reinforcement with additional fasteners or using better weather strips. Again, I have never seen 'better' or even window kits sold separately, since all portable A/C units already have the kits that come with them, and there is no 'universal' kit that would fit your unit in-stock. If the unit will be there for a while and you have the tools, you can fasten the panels using small screws AFTER the holes have been piloted with a drill bit to eliminate cracking. You can then place weather stripping as well silicone caulk sealant to ensure it stays put. These are just some options, but I hope this information has assisted you.

Thank you for your response. Yes, that is the model. I have sent an email to Haier, let's see what they say. I will also try to seal the gaps, with some cardboard and foam strips/pieces (to cover/overlap the entire space which should be covered by the window kit). Still think this is a product design deficiency, there should be a better way 'out of the box' - without 1/8" gaps.fix car ac cost You are quite welcome, I just hope you get the proper solution for your a/c unit.placement of ac unit Keep us updated on your progress, I want to see what happens.cost of new hvac for home I had sent an email to Haier's customer service, but sadly they never answered my original question. I tried 2 plexiglass pieces, but given how poorly the existing window kit is designed, I always ended up with gaps.

I have now used the 2 pieces of plexiglass plus the window kit from Haier, and used a lot of caulk to close the gaps. It should get me through this season. Preferable, I would find a plexiglass store in Manhattan that can cut a single piece (45 1/2' wide, 6' tall) with a hole in it for the exhaust that would fit in front of the Haier window kit. With a little caulk, that would allow a good seal (sound and air flow are concerns - in that order). I am happy with the performance of the AC unit, by the way. Works well, does the job. Just the window kit is not good for metal windows of the size I have (I rent). Hmm, sorry to hear about your experiences with Haier, no bueno. I really wish we still cut plexiglass in our stores, but alas, that's been several years since we've done that service. As long as what you have now will work, and that you used good plexiglass, such as Lexan. I know this wasn't the result you wanted, but thank you again for updating us on your situation. 

The next time I encounter Haier or even another portable A/C unit, I'll be sure to let my customers know about the window kits. And if there is anything else by way of home improvement projects you like to discuss, feel free to talk about them here. At least with the temps rising, you have a working A/C unit, albeit one with some gaps. Written It's not a technical limitation, if it's a must we can built a machine which can bring down temperature to 0°C, but that's not the point here, after all we are not looking for a cold storage, right??The purposes of Air-Conditioner itself is to provide a comfortable temperature for the occupants, not an unbearable temperature for the occupants..!16°C temperature is already too low temperature for a human body wearing normal cloths. For infants and people wearing normal cloths this would create problems.22-24°C and 50% relative humidity is the most comfortable temperature for human body(Will change depending up on clothing, center, age air movement etc).

More over for getting temperature less than 16°C will need lot of power consumption, The size of the compressor itself should be big enough to do the additional work.Also too low temperature will reduce the humidity inside the room, as you might have seen water droplets coming out of Air-Conditioner, If temp set is too low, lot of such water vapours will be removed from the room which will make our skin dry..! Thanks Aravind Srinivasan for A2AWritten If you think that there maybe some technical limitation then thats wrong , We can achieve Low temperatures too but the main thing to be considered here is the Comfort of Individual.So what is the observed comfort level ?ASHRAE- American society of Heating, Refrigeration and Air conditioning Engineers did a survey on the basis of the Comfort levels of various people for both winter and summer conditions and finally developed a Comfort Zone. Following is the Comfort chart:Written It is not limited technically, you can also reach below 16, but generally humans will feel comfortable for temp.

range between 20-28 deg C. If atmospheric temp is below 16 deg, AC can be designed for providing heated air, (DONE in cold countries). AC generally controls three things- 1. Apart from that it also filters the air for dust and unwanted particles. Air conditioner is for providing comfortable atmosphere by controlling above three parameters for air.Written In order to compete with other air conditioner manufacturers.Yes, an air conditioner could be designed to achieve lower temperatures, but this would require a more powerful compressor, more heat exchange area, more refrigerant. Great, now my AC can achieve a lower room temperature that none of my customers want, and everything is bigger, meaning more costly and requiring more volume. My competitors, knowing that there are very few consumers wanting an AC that can achieve 10C in a fixed volume within the design specs, have a cheaper manufacturing cost for a unit. The consumer will pay slightly to nothing more for the additional range, so my contribution margin per unit decreases.instead, I accept that the industry standard for these units is 16C, which is about 3C below the room temp the majority will ever use the unit for, and design accordingly.
