Comments: This review is for the Soleus Portable Air Conditioner and Heater (model PH3-12R-03) that I recently purchased. I regret to say that I am disappointed in this product mainly due to the excessive noise level. I installed the unit in a living room, where it is too loud to comfortably have a conversation, watch TV or listen to music when the air conditioner mode is running. The noise level when using the fan mode is not a problem. I was also looking forward to using the heat mode to supplement my electric baseboard heat in the winter. Since the heater requires use of the exhaust hose, I will not be able to utilize this feature since the installation is not air tight enough for our severe wind and cold winter temperatures. The response from customer service regarding my concerns was a quote from the operating instructions re: a 45dB noise level. Not so in AC mode!

Review Title: Excellent product at a great price!
Comments: Purchased this A/C for a glass-enclosed patio that receives a lot of late morning/early afternoon sunlight. The first unit we received had trouble cooling the room, then stop cooling entirely after about 2 weeks of constant hard running. Contacted Air&Water and received the very best of service - received a new unit in just a few days with a minimum of hastle! New unit is marvelous - keeping the room cool during the day and COLD at night. Followed all the suggestions for insulation and venting of exhaust and everything is working as advertised. Highly recommended if bought through the right retailer!

Review Title: Portable AC
Comments: I have been using my portable ac unit for several weeks now and I can honestly say it has been very useful. My shop isn't insulated but made of concrete block. I use fans to help move air around during the summer. This past summer has been a scorcher. My portable ac unit really helped me out. It comfortably covers a 15' diameter are especially if you supplement with another fan. My only problem with the unit is the short distance of exhaust tubing so the unit must be within 5' or less from a window. This is a floor unit so if your windows are high from the ground you have even less room to exhaust. Otherwise I would have given a 5 star rating. The unit is powerful and the sweeping motion is great. I noticed some reviews mentioned the Celsius readout but this is as simple as reading the instructions to set to Fahrenheit. The set up was simple and very well packaged for transport. Very good addition to my shop!

Review Title: Not what expected
Comments: The oscillating fan does not work and the remote, the original and the replacement, does not work. It does work for the purpose needed but does not live up to my expectations.

Review Title: Cool choice
Comments: With this record setting heat in Texas hhis summer overwhelming most whole house air-conditioning systems, I wanted a solution for my home (upstairs, primarily) that could supplement my two straining a/c systems. After doing much online research, finding this well-respected brand with great specs at a great price made my choice easy. It's portability, easy install and powerful cooling in whisper quiet mode exceeded my expectations. Being also a portable heater for spot winter warmth needs was the icing on the cake! I don't think I could've done better!

Review Title: Happy with my soleus
Comments: This is a fantastic product. We have alot of humidity and it works great. We have it in our living room and it cools the entire main floor of our home. It makes a little noise with the blowing, but the performance out weighs the noise.

Review Title: Good alternative to upgrading the central ac unit
Comments: We were faced with the need of upgrading our central ac unit just to have ventilation in our "finished" downstairs bedroon/den immediately after moving in to our new house. But then discovered this unit! For just under $400 we were thrilled to have a properly sized ac unit, heater for the winter months, fan and dehumidifier all in one. It cools the room very well and all it takes is venting it through the partially opened window that you may need to secure with some strips of 1x2 wood like i did and be sure to connect the supplied drain hose to the condensation drain port and set into a plastic container of some kind because this unit produces a lot of water. It is a great portable unit overall. We had an issue with it to begin with when it arrived that the onboard tank for condensation leaked, but it was promptly replaced with no trouble and the new one that was sent has been trouble-free. It just made sense for now to go this route because of the economy and all the uncertainies, spending big bucks to upgrade the cental ac unit was just too big an expense. So thank you for making this available at such a great price and giving us a more comfortable environment to sleep sound by being able to control the tempature in our bedroom area.

Review Title: Wonder where the asthma went when you cool your house with SOLEUS
Comments: My son has disabilitating asthma and needed an air conditioner w/heat in his little make shift apartment. He needs very clean air and low humidity to breathe well.The Soleus portable air and heat was a perfect match for him. This winter will be the first winter using the heat and he is really looking forward to warmer air to breathe and I looking forward to a lower electric heat bill.We really like the portability of the Soleus and the quietness..We don't have to turn up the TV now. The price was great and it came in good time.My only regret was that we didn't get it sooner..
