The newest portable air conditioner models have built-in dehumidifiers. This helps remove moisture from the air and makes the environment healthier because it eliminates bacteria and prevents the growth of mildew and mold.
Consumers should be sure to choose a reputable brand. Companies that have an established reputation in the industry will produce better equipment. Consumers who buy a popular brand can be sure the system is durable and will perform as promised even after long-term use. A generic brand air conditioner may not have a warranty and may not meet the same standards for safety and quality.
Some portable combo units provide better performance all year round. In some cases, the air outside the home may not be the correct temperature for the unit to work efficiently. Certain units will work much better when the air drawn in is cooler.
When purchasing a portable AC and heater unit, ask the retailer what the temperature should be for optimal performance.
Finding the Right BTU Level
A BTU is a standard unit of measure for the amount of energy necessary to maintain the desired temperature.
The unit you purchase should have the right BTU level for the room size. If the unit has a larger BTU capacity than you need, it will waste energy and cost more to operate.
You may find that exceptions to this rule apply to your situation. If the room is occupied by large numbers of people constantly, receives direct sunlight exposure most of the day or is excessively hot, you may need to purchase an air conditioner with more BTUs.
Portable AC units come in a wide range of sizes. Smaller units use less power but take longer to cool the room.
