The first question you have to address is whether you want to buy a portable AC unit or a window air conditioner if you don't have central air and need to cool a room ASAP. If you can't install a window air conditioner in your space because of design limitations or building restrictions, a portable air conditioner is the best route. If you’d like a mobile air conditioning unit that can be moved from room to room or stored away at the end of the season, It’s also a better pick.
Portable Air conditioning products occupy floor space, so it is important to actually hold the additional square footage for starters. That will likely mean a longer hose and more space taken up, although you want to place the unit away from walls so the airflow isn’t restricted. Which is one more downside, since they call for an exhaust tubing to get removed and re-installed each time it is actually moved to one more area. For correct productivity, you have to be sure the exhaust hose is really as straight as possible as kinks can restriction the efficiency.
A portable AC fails to operate with no exhaust garden hose. They have to be vented on the outside the house because they are extracting the oxygen you want launched beyond the area. You can elect to vent by way of a windows (most typical), ceiling and wall as well as door in principle.
If you want a portable unit with no venting to the outside, since there are no portable ACs without an exhaust hose, you may want to consider an evaporative cooler. They require a large amount of h2o to cool the place and are perfect in dried up temperatures in which humidity levels are very low and the atmosphere is hot.
