Excerpt: This air conditioner is great. It cools off most of the first floor of my house and I haven't had to empty a water bucket yet. The instructions are a little hard to read but the pictures help. The only problem that I had was the need to cut the piece of plastic to fit in the window but once that was done this is the best air conditioner in my house. The price is even the best that i could find. I will certainly buy another one of these for the rest of my house.
Summary: It works very good in air conditioning and heatpump heating our apartments approximate 800 sq ft area, with help of additional fan for complete circulation. I can't get the auto season part to worrk, it stays on that circuing arrow symbol. I also wish its fan had a contineous run mode in heatings off/on cycles. Otherwise its works very good in cooling and heating, reducing our heat bill by over half due to its new heatpump technology.
Summary: I would give the AC a 3.5 or 4 out of 5 stars. The heater gets 1 star because it is not actually a heater but a 'heat pump'. Heat pumps don't work at temperatures below 40 degrees (F), so it is essentially useless in Northeastern Ohio. The listing makes no mention of the heat pump feature, and I purchased it assuming that it wasn't a heat pump. This was a big purchase (several hundred dollars) and I wanted a unit that could cool in the summer and heat in the winter.
Summary: I bought this unit for single room supplemental cooling. The heat pump aspect was just serendipity. Have used it to get the early mourning warm-up and have been pleasantly surprised at how well it works. I set it up as a single hose exhaust and found the supplied hoses were easy to install. The unit is reasonably quiet with not more sound than a fan running on high produces. Summer has not arrived, but would expect the same result.
