How to Pick the Right AC for Each Room Type
| June 8, 2025
If you think about it, cooling every room in the house doesn’t always make sense. Maybe you just need to cool your bedroom at night, your home office during the day, or a guest room when family visits. Portable air conditioners are perfect for the job —they give you the flexibility to cool only the spaces you actually use without wasting energy on the rest of the house.
How to pick the right portable air conditioner?
Portable air conditioners are usually rated in two ways: by the size of the room they can cool (in square meters or feet), or by BTU (British thermal units), which measures how much heat the unit can remove. Simply multiply the length by the width. But remember, high ceilings mean more air to cool, so you may need a stronger unit. Things like poor insulation, lots of sunlight, drafty windows, running electronics, and humidity can also make it harder for the air conditioner to keep the room cool.
Our Crownline PAC-405 is a great example of what to look for in a portable air conditioner. With a strong 12,000 BTU (3500W) cooling capacity, it can quickly cool rooms up to 25 m², which makes it perfect for spaces like bedrooms, living rooms, or small offices. On top of that, it delivers powerful airflow with a maximum air volume of 410 m³/h, helping the cool air spread evenly throughout the room so you feel comfortable faster.
The best cooling technology
The PAC-405 works best in temperatures between 18°C and 32°C, making it ideal for most homes in the UAE. Even with its strong cooling power, it’s designed to be energy efficient, using only 1350W and 6A while running.
