I recently purchased the Costway Portable Air Conditioner and Heater for our home gym in the garage, and it has been an outstanding addition to our household. Its ease of installation, powerful performance, and convenient features make it an excellent investment for anyone in need of a reliable climate control solution. Setting up the unit was incredibly straightforward. My husband managed to install it by himself in less than an hour. The clear instructions and included installation kit made the process smooth and hassle-free. It was up and running in no time, ready to create a comfortable environment. The Costway unit is impressively powerful, efficiently cooling our garage, which serves as our home gym. It maintains a consistent temperature, ensuring a comfortable workout space regardless of the weather outside. The dual functionality of both air conditioning and heating means we can use it year-round, making it a versatile addition to our home. One of the standout features of this unit is its remote control and app functionality. The remote control allows for easy adjustments without having to pause our workouts. Additionally, the ability to turn the unit on beforehand using the app is incredibly useful. I can ensure the gym is at the perfect temperature before we even step inside, which is a fantastic time-saver and adds a layer of convenience to our routine. Also, it is very energy efficient which was one of my main concerns. Read more

It works well. The window kit was broken when I got it. Luckily, it fit into my old window kit. Easy to install, quiet. Read more

I have 3 of these units in my home. When the power from PSE fails due to a problem causing an Outtage for our area they keep us warm. The lights in our home stay on we have hot water and our entertainment center is operational during our sometimes 3 day PSE power outtage. These units draw very little power when they heat or cool. My 50 amp Westinghouse Generator can power everything in my home thanks to the low Amp draw from these CostWay 15,000 btu Heat Pumps. Our home is always comfortable and warm even when we have a PSE Winter power Outtage. This is an honest review! Lord Dragoni Read more

I bought this to try to keep our entire garage space cooler, and I am very happy with the results. The set up was super easy basically just take it out of the box and it comes with everything it needs. It also includes a heat feature which you don’t see all the time. I just started using this, so I will keep you updated on its performance long-term. But to me it seems like it’s going to be a great quality unit the lasts us a long time. Read more

I don’t know why it does like a car where it gets quiet and then fires back up and is noisy and it does it constantly. Read more

The media could not be loaded. This unit is so worth it considering it both heats and cools. It’s super quiet and is just like the name brand ones that are almost double the price. I use it in my garage and it keeps the temperature At my desired range without making my electrical bill astronomical! I don’t regret this purchase at all. Read more

First, the item shows up with a broken window kit. So that delayed getting the unit going. Once I did receive the kit, the remote wasn’t responding anymore. What’s worse, now that I’ve waited 5 extra days for the window assembly kut to arrive, the machine blows air. The 300 sq ft room stayed at 81 degrees for over an hour before I gave up and went to a box fan for better circulation. To top it off, customer service says I need a pipe that draws hot air into the unit from outside, to make cold air. When I tell them all pieces are present, they insist now they didn’t send enough parts. First, the product description speaks nothing of drawing air in, second, it only describes an exhaust system. Needless to say I’m disappointed that my intelligence has been insulted at this point with back and forth needless customer service emails. STAY AWAY! Read more
