How to Find the Best Small Room Air Conditioner for Your Space

When the weather gets hot, there’s nothing better than having an air conditioner to cool down your living space. But what if you live in a small apartment or have a tiny room that needs cooling? The good news is that plenty of small room air conditioners are available on the market. However, with so many options, it can be challenging to choose the right one. That’s where we come in. In this article, we’ll provide expert tips on selecting the perfect small room air conditioner for your needs.


Determine the BTU Rating You Need

The first thing you need to do when choosing a small room air conditioner is to determine the BTU (British Thermal Units) rating you need. BTUs measure the amount of heat an air conditioner can remove from a room per hour. Generally, you need about 20 BTUs per square foot of space. So, if your room is 150 square feet, you’ll need an air conditioner with a BTU rating of 3,000. Here’s a quick guide to BTU ratings and room sizes:

  • 5,000 BTUs for rooms up to 150 square feet
  • 6,000 BTUs for rooms up to 250 square feet
  • 7,000 BTUs for rooms up to 300 square feet
  • 8,000 BTUs for rooms up to 350 square feet
  • 9,000 BTUs for rooms up to 400 square feet
  • 10,000 BTUs for rooms up to 450 square feet
  • 12,000 BTUs for rooms up to 550 square feet
  • 14,000 BTUs for rooms up to 700 square feet

Consider the Type of Air Conditioner

Three main types of small room air conditioners are window, portable, and wall-mounted. Here’s a brief overview of each type:

  • Window air conditioners are the most common type of air conditioner for small rooms. They’re easy to install and are typically less expensive than portable or wall-mounted units. However, they can be loud and take up window space.
  • Portable air conditioners are versatile and can be moved from room to room. They don’t require installation; you can take them with you if you move. However, they can be noisy, and the exhaust hose needs to be vented outside.
  • Wall-mounted air conditioners are the most expensive option but offer the most permanent solution. They’re quiet and don’t take up window space but require professional installation.

Look for Energy Efficiency


When selecting a small room air conditioner, it’s essential to consider energy efficiency. An energy-efficient unit will help save on your utility bill, and it’s also better for the environment. Look for air conditioners with high SEER (Seasonal Energy Efficiency Ratio) ratings, as they consume less energy while providing the same cooling effect.

You can also opt for models with programmable thermostats, which allow you to set a specific temperature and avoid wasting energy by cooling the room unnecessarily. So, make sure to choose an air conditioner that’s compact, efficient, and good for the planet and your wallet.

Consider Noise Level


When choosing a small room air conditioner, it’s essential to consider the noise level. Some units can be quite noisy and disrupt your peace. Look for air conditioners with a low decibel rating, indicating they operate quietly. You can also opt for models with multiple fan speeds, as lower fan speeds are generally quieter.

Another option is to look for air conditioners with noise-reducing features, such as insulated cabinets and vibration-dampening technology. So, consider noise level when choosing your small room air conditioner to ensure a comfortable and peaceful environment.
