Haier HPND14XHT 14,000 BTU Portable AC

Super quiet! This 14000 BTU portable unit is so much quieter than my 12000 BTU wall-mounted Kenmore A/C (which is only about 4 years old), that I am thinking about buying another of these portable units to replace my wall-mounted A/C. I live in a 2 bedroom apartment. There is a 12000 BTU wall-mounted Kenmore A/C in my living room, which is enough to cool about half of the apartment. It does not cool the bedrooms. The apartment management does not allow tenants to have window A/C units. My only option is to use a portable unit. I did a lot of research, and decided to buy a dual-hose portable unit because the single-hose units draw outdoor air into the conditioned space. Single-hose portable air conditioners are terribly inefficient. I also looked at reliability, and decided NOT to buy a portable A/C made by Whynter, because they have terrible long-term reliability. This Haier unit scored well on both reliability and efficiency. I ordered one on Amazon, but the seller cancelled the order without any explanation. I assume that it was out-of-stock. So, I bought a manufacturer-refurbished unit on the largest e-auction site for $80 less than the price on Amazon. This air conditioner is so quiet that I can easily watch TV while it is set to the highest fan setting! I can't watch TV comfortably with my wall-mounted Kenmore A/C, even when it is set to the LOW fan setting. I may buy another of this Haier A/C. If I do, I will build my own custom exhaust adapter for my sliding glass door. Several reviewers have commented that the hoses sometimes become dislodged from the window kit. I can certainly see how that can happen. So, I bought some self-drilling screws from that big-box hardware store with the orange logo... and I used screws to make sure that the hoses will never become dislodged. Also, I used Gorilla tape to seal the whole thing to prevent air leakage. Take a look at my attached photos for details. EDIT: Although the photos appear to show the exhaust hoses in a horizontal position... I want to tell you that my window opens left-to-right, not up-and-down. So... my exhaust hoses are mounted in a vertical position. The larger hose is the (warm air) exhaust hose when using the system to cool the living space. So, I installed the larger hose ABOVE the smaller hose. I believe this should help with efficiency because warm air rises. I may modify the components in the future so that the end of the hoses is separated by more distance (to prevent air expelled by the exhaust hose from being sucked-in by the intake hose). EDIT: After I bought my first unit from SmartSurplus on that big e-auction website, I decided to buy another one. The second unit arrived damaged. It looked like it was dropped during shipping. The seller asked me to send them pictures of the damage. Then, the seller sent me another unit. I didn't need to send the damaged unit back to the seller. They didn't charge me anything extra. The replacement unit works fine. Unfortunately, they didn't send any of the hoses/accessories with the replacement unit. I was hoping to receive a set of hoses/accessories so that I would have some spare parts. But I didn't need to pay for return shipping or any of that hassle. Another edit... December 2018: I have had two or three opportunities to use it as a heater. It is way more efficient than the electric baseboard heaters in my apartment. I have used it when the outdoor temperature is down to the high teens (15-19 degrees Fahrenheit), and it cranks out plenty of heat. My only complaint is that the condensate tank fills up in a single day. The condensate tank is very small. It doesn't fill up when cooling... but it fills up quickly when heating. So, I have ordered the Little Giant condensate pump here: https://www.amazon.com/gp/product/B000SM342Q/ I bought tubing and fittings at Home Depot to connect hoses to the upper condensate drain. RIght now, I am running the heater to confirm that the upper drain will drain down into a container, while the lower drain stays dry. I will update my review after I have proven results.
