post #1 of 18 (permalink) Window type A/C unit short cycles post #2 of 18 (permalink) Re: Window type A/C unit short cycles Hey Chris, sounds like your compressor is tripping off on a thermal overload. Fancy term meaning it's overheating, after it cools down a spell, the internal overload protection resets itself and starts back up again. That being said, it could be from being low on charge, which means there's a leak. Or a restriction in the refrigerant circuit, which means if there's not enough refrigerant getting back to the compressor, neither is the oil in the system, which could result in overheating. To be honest, unless you know someone in HVAC/R who could do you a favor, it's not worth the money you'd have to pay just to have a guy open the cabinet to diagnose. We call those "window shakers" down here, just toss 'em out when they act up. A new one would save you money in the long run, plus you get a warranty. Just my 2 cents... I'm sure when Dean sees this, he might be able to offer something else, he's been doing this a lot longer than me.

Try spraying through it about 5 minutes with a hose. If that doesn't do it then any other repair isn't worth the money. It will cost you $150 for someone to come out, $200 for a new one - do the math post #6 of 18 (permalink) Well, we chose to just replace them. We have two of them and they are estimated to be as old as the building (condo), so probably 20 plus years, more likely 30 in reality. Place was built in the late 70's. I picked one up from Costco and my wife is bringing one home from Target tonight.

Both are 8K BTU but Costco was out of the 8K so I had no choice to get an oversized 12K BTU unit. Originally Posted by MAD70SS396I actually do know someone in the HVAC/R business. I actually just started a new career in HVAC repair a few weeks ago and am almost finished with school in HVAC. Your mentioning of the thermal overload was another thought that crossed my mind. Honestly, my first thought was the compressors are just getting weak and unable to move the refrigerant vapor around anymore because of age. Even if I wanted to, I dont have the tools necessary to remove and solder in new components, then install fittings and recharge it anyways. It takes R22 which is kind of expensive anyways making it not even worth the effort no matter if I had the tools or not. If I were to mess with it, it would only be for learning and educational purposes and not to be re-used again.

I knew these units werent really serviceable so to speak, but I didnt realize they utilize the condensate to help cool as well. I have a lot to learn in this new career in HVAC. post #7 of 18 (permalink) Originally Posted by 85 SS Oops, forgot to quote this one. I actually did try that, thinking the number one problem is probably restriced air flow. Went outside and looked up in there and there wasnt anything stuck to the condenser fins. Once I noticed the fins were clean and bare, I knew it was time for a new one. 250 bucks for a 12K BTU unit downstairs and another 200 for an upstairs unit. Bye bye car money yet again. post #8 of 18 (permalink) Maryland Chevelle Club #017 progress has little to do with speed, but lots to do with direction post #9 of 18 (permalink) Originally Posted by LeoP Boy is it ever, my god what a )(*&% pain in the ass this project has been tonight. First off I totally messed up the title of this post. These arent window units, they are actually wall units that run off 200V.

I didnt realize that window units and wall units were different sizes and one runs off 120V and the other runs off 200V, 210 220, whatever. So im very ticked and dissappointed in not only the work that we put in tonight to get these new AC units running, they look like absolute s&*t sitting inside an wall opening that they are clearly too small for. My wife and 2 other friends of ours that helped us install these things say they look just fine, I say no way in hell. You can see daylight through a few corners and there is absolutely no insulation around the perimeter to keep the hot air out in the summer and cold air in, or vise versa in the winter. As for keeping rain and bad weather from leaking right into the house? No way in hell this thing is going to seal in any case. I was also taken aback when I noticed the plug for these new units were not the 200V plugs that I took out, but 120V that I took out of the boxes. To me its like putting a half ton pickup in a 3/4 tons job. It just seems underized and just plain trashy and ghetto but what do I know right?

Then there is the other problem I found out, the real 200V wall units cost 500 dollars. I paid 200 dollars for a unit thats the wrong size and voltage. Anyone know who has a good deal on WALL AC units? post #10 of 18 (permalink) post #11 of 18 (permalink) The units that came out of the wall are much wider then the window units so it wasnt a direct fit. I would have to blend them into the wall with sheetrock and insulate them if I were to get these to really look right and be insulated. Which I dont have a problem doing, but they really arent the correct sized physical replacment. Currently, they are both kind of Mcguyvered in there. BTU for both units are 8000. Costco was out of the 8K so I had no choice but to get a 12K for the living area. Which im very strongly considering taking back to the store for a refund to put towards the correct sized unit. This one is roughly 19 inches wide. The units we took out are almost 26 inches wide. No need to rewire, the chord was able to reach down to a 120V outlet nearby.
