Oh yes they are.

Non-inverters are on and off machines. They always draw the maximum current. Either they are on or off. Every time the compressor turns on, it also affects other appliances because they have to use huge current to kick start the compressor. They maintain the desired temperature by turning off and on. No way to tell the compressor to just run at 25% to maintain desired temperature.

On the other hand, the inverter compressor versions is adjustable. It can draw as low as 100w just to maintain the desired temperature setting. I have this AC but with heater and by average, it draws 200-400w blowing just the right amount of cold air. If it's too hot, or you put it to maximum compressor speed and full fan speed, it can draw up to 1300w.
Yes I bought it and the sound noise is great. Sounds just like a fan. Night and day compared to my standard single hose condenser unit

really ? this guy on youtube did a side by side test inverter vs non inverter and he got around 40% savings.... so tested vs your opinion from what expertise ? anyway.... look up a video on youtube with the title "Inverter AC kWh consumption at 22 - 24 vs 26*C temperature (how much energy will you save)" and see the video for yourself.
Really. You disagree that you compare efficiency by comparing SEER rating? Where is your video? THe video you suggested has single mini split system run at different temp setting.
Inverter AC is not inherently more efficient. AC with higher SEER rating is more efficient.

I have an older model of this one from Costco when it first came out. Map14hs1twt. The old one has a ceer of 12.3 while the new ones have a ceer of 13.8.

Both use r32. The refurbished one arrived today. Unfortunately, the clip that keeps the hose attached to the unit for storage is broken. Not too much of a deal breaker though.

Anyone have a photo of it in use? Like can it sit to the side of a window and its hose directed to the window to the left or right?

Ok.... follow the link.... this is an actual SCIENTIFIC study of inverter ac vs non inverter ac done in saudi arabia..... all the data is included, peer reviewed..... just read it and see the 44% reduction in energy usage between inverter and non inverter https://link.springer.com/article...20-00033-y

also... I made no mention of seer rating or comparison of.... what I said was in support of inverter ac being more efficient than non inverter ac of the same capacity.

I got two of the heater/ac version as well and one of them works correctly with the evaporative system but the other one collects water like crazy. How did you rig up a separate pump? Did you just plug into the bottom drain
I unplugged the bottom hole and attached a tube. The tube goes into the little giant pump. The pump dumps it into a tube outside the window onto the lawn. Google Little Giant Condensation pump. It comes with a hose sometimes depending on the combo so dont order a separate hose.

ahh thanks for the info. Do you have the pump running constantly then?

NO, its a marketing BS. You are paying for COMFORT, not SAVINGS.. You need electricity to cool the room and inverter does not provide any significant savings.They have same SEER rating. it can provide more comfortable and less noisy environment . It will run longer time at slow speed and low power draw comparing to a normal AC which will run ON-OFF blasting cold air.
Which non-inverter are you comparing? I see this one has a seer rating of 12.3, at least based on the amazon listing page. Can't seem to find seer ratings for other models though including non-inverter.
