Imagine the possibilities for you as a building manager. It is quiet enough to use in your bedroom without disturbing you. You'll need your own calculations based on the conditions you face, but there are certain situations where portable AC makes sense. If it is oversized, the fan will "short cycle" - it will turn on at full power, satisfy the thermostat then shut off. Flat tires can be a major inconvenience and can happen at any moment. They are also easy to maintain compared to an HVAC, needing only occasional filter changes. Heat is the primary weather-related cause of death in the United States. They are mainly used in hot, dry climates, so depending on where you are in Texas, this might be a good cooling option for you. This makes them an excellent appliance for all-year-round use. These air-conditioners can be window, minisplit, portable or IoT (Internet of Things). When using ductless split systems, the compressor must be installed somewhere. An air filter will not work to stop the smoke as the air sucked through the unit won't come directly into the unit.
