Comments: Soleus LX-140 14,000 BTU Portable Air Conditioner With Built-In Heat Pump. using it primarily for heat in a poorly insulated older house with electric baseboard heat. last winter my heating bill was HALF using this. however in order to be useful as a heat source you MUST put it on a base at least about 12" off the floor and install a drain hose to the outside because the tank will fill up in a matter of hours without it.

Review Title: Soleus LX-140 for garage
Comments: I installed the Soleus LX-140 in my 24 X 30 garage. The garage is very well insulated both in the attic and walls. The garage is 720 sq. ft. so it does not cool it down a lot, but it also has been over 100 degrees for the last month. It was easy to install and set up.

Review Title: Great so far.
Comments: So far, we've only used it as an air conditioner. As long as we weren't trying to air condition a very large space, it was fine. It cooled us on the really hot days. It dehumidified the air as well during those hot days. The weather has not been cold enough for us to try the heat pump options on it, but we're anxious to try.

Comments: It doesn't cool very well at all! We ended up having to put a window conditioner in and thats what we were trying to avoid doing. Not sure about the heater part of it. the one good thing is that you don't have to empty the water very often or that would be a little of a pain in the butt!!!

Review Title: Soleus is #1
Comments: I bought a Soleus LX-140 last year for our upstairs bedroom. I love the exhaust system for the high humidity days NJ can have. No need to empty reservoir tanks on a regular basis. It was 18 months before the emergency tank needed to be emptied. Fast, easy, and back in use in no time. I have since replaced our downstairs unit with another Soleus.

Review Title: GOOD AC
Comments: plugged it in about 3 weeks ago and its purred ever since. Use it in a server room keeps it very cool. The only thing i dont like is the unit never kicks off like my last one did. I think it has something to do with the new type of coolant the r410A the last one used R12 and was cooler.

Review Title: Soleus LX-140
Comments: My wife & I recently purchased the Soleus LX-140 in an effort to comply with our building's air conditioner regulations. Overall, the LX-140 seems to be a good AC unit. The unit was extremely easy to install and I had it operational in a short period of time. This will also allow seasonal installation & repositioning an easier and safer task. Although it cools the living room and kitchen to a comfortable temperature, I feel the LX-140 takes a little longer to accomplish this when compared to our older AC window unit. In addition, the LX-140 is also slightly louder than our older conventional window unit. Despite these two issues, I would highly recommend the Soleus LX-140. My only recommendation would be for Soleus to add some sort of plastic or wire mesh/netting to the kit so the owner could prevent the possibility of the window mounted intake/ exhaust vents & hoses from becoming a bird sanctuary.

Review Title: Great Product
Comments: We needed a solution for a small room that had some network equipment in it. It was internal to the building and had no vents. SO we put this machine in the room and put the vent into the wall and up to the roof. It has kept the room cool from day one and my network equipment has been cooled every since. Worked just as advertised. Great Machine.

Review Title: Best investment we've made
Comments: We have a 450 s/f glass enclosed sunroom with French doors going from our home to the sunroom. Our a/c - heat pump is not large enough to cool both the house and the sunroom. We purchased the Soleus LX-140 to supplement our home unit and are thrilled with the ease of installation and the efficiency of the unit. It cooled the room within 20 minutes and now we can finally open the French doors to the sunroom! We haven't used the heat function as of yet as the outdoor temp has been average 90 degrees every day. Thank you Air-n-Water for hassle free ordering process, & prompt shipping.

Review Title: Good cooling.
Comments: Good cooling of my loft style bedroom even with nearly 500 sq ft and 15 ft ceeling and the open loft. Been starting it about an hour before bed on high and the bedroom has been nice and cool by the time I am ready to head to bed. It was a good buy for sure. Delivered in 2 days.

Review Title: Great Product!
Comments: We are using the Soleus in our small cabin up north. We have used all its features including the heater for those cold mornings this last spring. The auto feature we especially like since the temperatures can fluctuate a lot up north and this product will give us heat in the morning and go into air conditioning automatically as the day heats up if it is needed. The fan runs a little noisy but that's a small price to pay when the heat and humidity are way up there and you're trying to stay comfortable in a small cabin. It was very easy to install. We're glad we purchased this product.

Review Title: Quality Service
Comments: Used to supplement central air conditioning for a phone switch room. Rep I talked to very professional, tried to make sure I understood ALL the product features. We needed the item right away, cost of next-day air seemed a bit high, but acceptable given the discount available that day. Unit arrived before noon the next day, we put it in and it hasn't blinked since. Since the unit is a heat pump, virtually no moisture in the exhaust air. Thank you!!!

Review Title: Working well!!
Comments: We bought the Soleus LX-40 for out small cabin up north. The heat portion works well to take off the chill in the mornings the temp dips down. The thermostat feature works well too! We haven't used the air conditioner yet but we know it will do a good job. We have used the fan at night and it has proved to be a welcomed thing to help move the air in the loft. Installation in the window was a snap! Thanks for a great product.

Review Title: Machine ruined my wooden floor and carpeting
Comments: This machine is described as having no buckets to empty. This is not true!! Within three days, we awakened to a flooded floor with the bucket light illuminated. We exchanged the machine for no less than 3 machines, which all did the same thing. However, with the other two machines, we had learned to have a catcher underneath for the water. We have since reverted back to a window unit. The floor is ruined and so is the carpet, so the machine is definitely not recommended.

Review Title: Haven't used it much yet
Comments: Purchased a portable AC for our masterbedroom. We have not had to use the AC yet, but have used the fan. The unit is remarkably quiet and the vent kit works well in our sliding door. The whole thing looks kind of like an R2D2 unit from Star Wars. Hopefully we won't have any 85 degree nights in our bedroom this summer.

Review Title: PERFECT!
Comments: This unit started cooling as soon as I turned it on. My temp gun showed temps coming out of the unit in the low 30F range (Only for a few seconds as I was just making sure it was working before I fully installed it. Also I'm not saying it gets the room that cold but does pump out very cold air to keep your room cool). The quality is great, even the accessories. I had the New Air 1400 and it was CRAP! I use it to keep my snake room (36 heaters in all and ranging heater temp is 83F and also a bay window facing south) from getting to hot! So far I am happy with the unit.

Comments: My parents love their portable air conditioner. As a matter fact, the portable air conditioner does such a good job cooling their room that they need a blanket at night because it gets too cold.
