According to me, the best portable ac unit brand is that which the consumer can find to be reliable and can possess without spending a lot of money.
I am going to talk about EdgеStаr brand that I consider to be the best in the industry. This is just my opinion.
EdgeStar has a number of units ranging from small EdgeStar Ultra Compact 8,000 BTU Portable Air Conditioner – White air conditioners to large units like the EdgeStar 14,000 BTU Dual Hose Portable Air Conditioner & Heater that is ideal for server rooms and even homes at times.
Most units from this manufacturer are relatively cheap if you compare them with similar ones from other brands. This does not mean that they are low quality units.
On the contrary, EdgeStar is my best-selling brand right now. Their units come with great features such as the patented Z-spray auto drain, ability to be controlled by a remote and can be said to be environment friendly.
This is what makes up a great unit and my customers emphasize this even further. The only complaints I have received are usually cases where a customer ordered a wrong unit for their home.
