A portable air conditioner basically works the same way as a traditional system. However, it doesn’t have the complex installation requirements that a traditional system does. It’s designed to cool individual rooms and is a great option for rooms without cooling systems or that don’t need cooling all the time. It can supplement a larger A/C unit.
To make sure you find the best portable A/C for your home, consider the following factors:
Portable A/C units are rated in BTUs (British Thermal Units). The higher the BTUs, the greater the cooling power the unit has. You should buy an appropriate portable A/C for your room size to avoid wasting energy. Use these general guidelines:
- 7,500 BTU will cover up to 150 square feet
- 9,000 BTU will cover up to 250 square feet
- 10,000 BTU will cover up to 325 square feet
- 12,000 BTU will cover up to 425 square feet
- 13,000 BTU will cover up to 475 square feet
- 14,000 BTU will cover up to 525 square feet
All portable A/Cs dehumidify the air as they cool it, so you’ll need to drain the collected water after several hours or days. If you want less maintenance work, go for self-evaporating models. They evaporate most or all of the moisture they collect.
A portable air conditioner can vent out warm air through a window, adjacent wall, drop ceiling, or attic. If you’re planning to exhaust your A/C through your attic or drop ceiling, moisture shouldn’t be exhausted with the air. For that reason, you shouldn’t buy the evaporative type.
If you’re planning to use the portable A/C in your work area or bedroom, you’ll need to pay attention to the noise level. Make sure you compare the decibel levels that different units produce.
Don’t forget to look at a unit’s EER (Energy Efficiency Ratio) rating. The higher the rating, the more energy efficient a unit is.
The right portable air conditioner will meet your cooling needs conveniently and efficiently. For more information on portable A/Cs, contact Beyer Boys, serving the San Antonio area.
