NewAir sent me their one of their AC-14100H units for review and I had a fun time checking out all of its features and putting it to the test. Overall, it performs very well, and was painless to set up and use. I am asking a lot of it to cool my entire garage, but it is so nice to have inside the house as well, in any room around 500 square feet. My garage was over 650 sq ft so it was a big task, and setting it to run in the morning, I was able to keep the temps to a reasonable low 80s with the door closed while it was over 90 outside. If I had a smaller garage, or one in partial shade, it would definitely cool much easier. My favourite feature is that it can switch between heating and cooling automatically as you just set the temperature. Everything feels well-made and of high quality.

I purchased the item new from NewAir. Initially I had to contact support, and their response was prompt and very helpful. I highly recommend the 14100H unit and the NewAir company.

Great System for Summer and Winter

I do alot of work in my un air-conditioned garage, and I needed something that would heat and cool with out having to cut a large hole in the wall for a window unit or install central air. I have had this for about a year and I cannot say anything bad. It has all the accessories with it so you can vent it through a window, or a wall through a small cutout. This is a big unit and it did a good job cooling and heating my uninsulated garage. Now you cannot expect this thing to keep it at 59 degrees in 100 degree weather, but it does a darn good job. The heater does a very good job for being a heat pump. It has held up through painting, saw dust and general abuse, but has not given me any issues. The best thing about it is the condensation goes into a little jug instead of the garage floor. I would recommend this to anyone as long as they understand this is portable, and only works as well as your environment. If you had this in an insulated room it will freeze you out

NewAir AC14100H quiet and excellent temp control.

we have a large room above our garage that my wife uses as her art studio and controlled temperature is very important. We had a Newair AC10000H that we ran 24/7 continuously for 8 years and the motor finally quit. We went to the AC14100H larger unit this time. So far we are impressed with how it maintains temperature and how quiet it is. This unit will run continuously to both cool and heat this room.

Replacements cannot be bought
on May 10, 2021
Posted by: vodkoce
This AC unit is good at keeping the room cool but I'm disappointed in the lack of replacement parts availability. Most exhaust hose diameters are 5" or 6" and this one is 5.59" which makes it very difficult to a get a new window installation kit. If I cannot find a replacement kit, I'll have to find a new AC to buy making this a bad purchase
