Yes
It’s a wall unit. It was on all night and day, full blast. I mean it was 104 outside that day or so. I am not just thinking it doesn’t work because it took too long. It’s becuase I was up at 4 am facing a health hazard that was new to me, from the temp in the apt.
I still see the delta getting colder and colder too. And they will tend to converge relatively over time. Is that wrong?
It’s worth noting that I have 4 panes of glass for windows, two double panes, one of those a sound proofing system. All sealed up tight for the whole heat wave. (It is top floor)
Also I have installed a transom with a dual fan on top of a bedroom door to maximize circulation.
Coupla notes, though I don’t know that you’re going to listen.
1)It doesn’t matter how many panes of glass you have, if your apartment is hot, it’s because heat from outside is getting in. It doesn’t matter how it’s getting in, it is. If it’s getting in faster than the AC can remove it, it’s going to get uncomfortable.
2)The hotter it is outside, where the AC is dumping the heat to, the more the AC has to work. On those really, really, hot days, if you were to set up a sprinkler to spray on the condenser coils, you’ll find that you’re getting much cooler air inside and the unit won’t work nearly as hard.
3)I’m sure you know this, but I want to bring it up. The fans you set up inside the apartment make you feel cool and yes, they distribute the cool air the AC is making, but they don’t actually cool the apartment (technically they warm it a bit).
Should have said this before: It was underperforming so I called the dealer who advised me it was inside the warranty period and he made the calls for me and arranged the exchange. It’s a new compressor usually or so I was told. They take it away for service and leave a loaner, (at 2000 less BTU, and which is working fine this heat wave).
The dealer texted me that the company said they found no problem with the compressor. So I am stuck. Haven’t talked to the co yet. I texted my dealer we need to get on the same page.
I’m going to get a new one it looks like. I have no problem with that. It’s the idea of the warranty and then all this time wasting crap that’s annoying.
- it does matter because with less I would have higher temps. That’s the definition of mattering. i don’t follow the point. The glass also holds the cold air in so your operation is more efficient.

Interesting. I’ll check that out. thanks

the transom and fans are the best idea I’ve ever had in my life. they make the temps in the apt consistent throughout, enabling the A/C to be in the LR, and to have no fan inside the bedroom proper at all. I had it done in February. O/W it’s a difference, or “shmelta” as we say, of about 8 degrees. as to the fans, you mean they are motors so they make heat?
Does that mean that the compressor is the only part of the AC they looked at?
You’re saying that the temperature of the air coming out of the A/C was 64 degrees? That means it was cooling the inside air by more than 20 degrees and any air coming in from outside by more than 30 degrees.
I’m sorry, but that’s a fully functioning air conditioner. My suggestion is to put fans all over your apartment to help move what cold air you have.
I didn’t mean that at all. I meant I had the thing set to 64 manually. IOW the lowest I ever bother to set it in bad heat. The temps I don’t know how to measure.
The air has to be colder to cool the room. It will be below the target room temperature.
Don’t be sorry. it doesn’t work. I imagine they are thinking about whether to replace the unit or let me just buy a new one, but they will lose my business if they do.
I’ll have to ask. Maybe theres something else they “forget” about.
That is a pretty big A/C unit for a 115V unit, but is still on the small size for a single unit to cool 700 square feet. Home Depot uses the following guidelines:
Also, 14,000 BTU is by no means the largest window unit on the market. You can get a 15,000 BTU unit that runs on 115V, and you can get much larger than that if you have a 230V supply. In fact, Home Depot sells 230V window A/C units as large as 28,000 BTU.
But if the unit is producing cool air, but is not adequately cooling the apartment, it may just be undersized for the space. Do you have another window you can put a second smaller unit into?
Plus, he says he lives on the top floor, which probably makes things worse. (Heat rises, plus the roof absorbs the sunlight.)
It may be, as the OP seems to think, that there’s something not right about the AC that’s making it not work as well as it used to; or it may be, as some others think, that it works as well as could be expected but it just isn’t up to the job. I don’t feel qualified to give an opinion either way. Were I in drad dog’s place, I’d be inclined to try closing off the room that the AC is in and staying in that one room as much as possible until the heat wave subsides (after making sure the filter was clean).
The temperature setting is not a valve that will increase cooling. the compressor is either on or off. If the return air is 86 degrees setting the AC at 75 will give the same cooling as setting it to 64.
If you really want to know if the unit is working get a simple thermoter and check the discharge air temp and compare it to the air returning to the AC unit.
If you want the space to be 72 degrees set the control to around 70 degrees you will get the ssame cooling as setting it to 64 degreees.
OK but it’s certainly a reasonable power for the job, in the margin, esp with my mods and innovations.
The replacement 12,000 btu has been great all through the over 95 degree days. Plus there is my history of living with this situation to consider. I will be happy with another 14,000 if it’s a good one.
There wont be any other units. They wont be necessary. I just made the transom this year. The whole system is at peak circulation.
Also I need a wall unit, and have no use for a window unit. I have done this shopping. I haven’t seen a 15k wall unit.
One of two things is in the immediate future: I get a new friedrich or I get a replacement frigidaire. Either way I’m good.
Right this second I am in a well cooled place, 12k btu loaner unit in the other room. The only problem I have is I won’t let that old unit back into my apt without an overhaul that I can understand. o/w it’s junk to me.
What does the setting do?
i havent tackled measuring the temp. Maybe I’ll look on youtube. I don;t think I’ll get a valid result.
Why do you think a 2 degree difference is right when 8 isn’t?
How recently have you checked or cleaned the filter in your old unit?
The setting determines when the compressor turns off.
If the space is 86 and the setting is set to 70 degrees the compressor is on
If the space is 86 and the setting is set to 64 degrees the compressor is on
In both cases you are getting the same cooling. But if the unit can cool the space down to temperature and it is set at 70 the unit will shut down when the unit senses 70 degrees. A little cool but as you move away from the unit the temp will be a little higher and confortable. But if the temp is set at 64 degrees the temp will have to get down to 64 degrees before shutting down. And now you are looking for a jacket because the room is too cold.
I think you are saying that the setting makes a difference in the temp the machine is going for and the eventual room temp. I think we all agree. I hope.
I think when you set it at 64 it’s probably not functioning right and you are trying to compensate. It never gets to 64 that I have seen. So no jacket.
