Air Conditioner Room Buying Guide and Tips

Buying an air conditioner for a room can be a bit overwhelming with all the options available. The first thing to consider is the size of the room, as a unit that's too small won't cool efficiently, while one that's too large will be wasteful and noisy.

A general rule of thumb is to choose an air conditioner with a capacity of around 1-2 tons for rooms that are 100-200 square feet in size. However, this can vary depending on factors like insulation, windows, and the number of occupants.

To ensure optimal performance, it's essential to select an air conditioner with the right air flow. A unit with a higher CFM (cubic feet per minute) rating can handle larger rooms and provide better air circulation.

When it comes to noise levels, look for air conditioners with a low decibel rating, such as 20-30 decibels, to minimize disturbance.

Bigger is not always better when it comes to room air conditioners. An oversized unit will cool the room too quickly without dehumidifying it properly, leading to discomfort.

Make sure to calculate the required cooling capacity based on the room size. Room air conditioners generally range from 5,500 to 14,000 BTU per hour, with 20 BTU needed for each square foot of living space.

When selecting an air conditioner, consider factors like room height, local climate, shading, and window size. This will help you choose the right size for your space.

Here's a rough guide to help you choose the right cooling capacity for your room:

Look for an ENERGY STAR certified model, which is 10% more efficient than non-certified models. Select a room AC with a lower Global Warming Potential refrigerant, such as R-32 (HFC-32) or R-454B, to minimize its impact on the climate.

If you want to save energy and money, look for an ENERGY STAR certified room air conditioner. These units use approximately 23 percent less energy and cost about $70 per year to run.

Most ENERGY STAR certified room air conditioners come with variable speed technology that saves even more energy and quietly keeps you cool. This innovation and energy savings are a big plus.

By choosing an ENERGY STAR certified room air conditioner, you'll not only save energy but also contribute to a cleaner environment. If all room air conditioners sold in the United States were ENERGY STAR certified, the cost savings would grow to approximately $1 billion each year, preventing about 12.5 billion pounds of greenhouse gas emissions annually.

To get the most savings out of your room air conditioner, follow these tips:

ENERGY STAR certified room air conditioners use approximately 23 percent less energy, depending on the product class, and cost about $70 per year to run. This can add up to significant savings over time.

The efficiency of a room air conditioner is measured by the Energy Efficiency Ratio (EER), which is the ratio of the cooling capacity (in BTU per hour) to the power input (in watts). The higher the EER, the more efficient the air conditioner.

To give you a better idea, here are the efficiency measurements for room air conditioners:

Look for the ENERGY STAR label when purchasing a new unit, as it ensures the product meets the more stringent EER2 rating. This rating is used for new equipment as of January 2023.

To ensure your home's electrical system can handle your new energy-efficient unit, you'll want to consider its power requirements. Smaller units, which draw less than 7.5 amps, can plug into any 15- or 20-amp, 120-volt household circuit not shared with major appliances.

A dedicated circuit is necessary for larger units, which require a 115-volt circuit. The largest models, however, need a 240-volt circuit to operate efficiently.
