Buying A Window Air Conditioner for Large Rooms 

Inspecting the Best Window Air Conditioner for Large Rooms

When shopping for a window unit, knowing the top choices on the market can give you a high point to start. However, picking the best cooling solution for your space requires you to find answers to some critical questions.

Why Do you Need a Window Air Conditioner for your Large Room?

Large-room air conditioning options come in many shapes and forms. So many would-be buyers wonder why they should choose a window air conditioner instead of a portable AC unit.

Below are five key benefits to expect from these useful appliances.

1. Cost-friendly

As you can imagine, the cost of a unit depends on factors like the brand, size, and features. Regardless, window AC units are generally inexpensive to buy and maintain. $200 is enough to get you a decent window air conditioner. With a few hundred dollars more, you can get a high-performing, efficient, and long-lasting unit with a generous feature set.

2. Energy efficient

If you want to stay cool on a budget, a window AC can be the perfect solution for you. Even the cheapest window air conditioner is much more energy efficient and will cost less to run. If you land a unit with Energy Star Certification, you can keep your large room fresh at a low cost.

Energy efficiency is important when choosing the Best Window AC for Large Rooms

3. Easy installation 

Window units are easier to install than central duct systems and ductless mini-splits. The installation process will vary from one unit to the next. Nonetheless, placing it on a window will not need a handyman or HVAC technician.

4. Adaptable for use in different places

A window air conditioner is just as straightforward to uninstall as it is to install. You can deploy it in one place and then quickly remove it to re-install it elsewhere. Thus, it’s perfect for non-permanent housing, dorm rooms, and temporary business premises.

5. Multi-functional

Many window ACs do more than just cooling. Some units have heating, cooling, dehumidifying, purifying, and circulating functions all in one package. A window air conditioner can be all you need for indoor air quality control all year round.

What Factors Should you Consider When Buying a Window Air conditioner For Large Rooms?

As you have learned, buying a window air conditioner can set you up for some great benefits. To enjoy them fully, however, you need to find the ideal unit for your room. Keep the factors below well in mind when you are out shopping for your future large-room AC.

  • Cooling Capacity

For the best cooling performance and efficiency, choose a window mounted air conditioner whose capacity fits your room size. A unit that does not have enough BTU power will work overtime and waste energy. On the other hand, a window air conditioner that is too large for your space will cool it, but it will not dehumidify it adequately. Your room will, therefore remain damp and clammy.

Manufacturers usually indicate the maximum size of space that a window air conditioner can cool effectively. So before rushing, measure your room and note down the square footage.

  • Energy Efficiency

Large room air conditioners are massive appliances. Large units often mean more energy consumption. For the most savings, start by looking at a model’s Energy Star seal. Energy Star certified conditioners use at least 10 percent less energy than average models.

A unit’s Energy Efficiency Ratio (EER) is also a reliable efficiency indicator. A higher EER indicates a more efficient air conditioner

  • Installation type

When choosing the right window air conditioner for your space, it pays to consider where you will install it. The most popular models fit inside double-hung windows. For these units, you need to measure the dimensions of your window, especially the width. 

All window ACs come with the minimum and maximum window dimensions listed in their specifications. Make sure your window’s width is somewhere within the range given by your unit of choice. 

Measuring dimension of the best Window AC for Large Room using tape measure

  • Electrical requirements

Many large-room window ACs are more powerful than most common appliances. A unit with 15,000 BTU or more will likely require a 220 to 240V power outlet. Meanwhile, small window air conditioners typically do with 115- or 125-volt outlets.

If you aim to get a large unit, ensure you have the electrical provision required. Electrical measurements will be part of an air conditioner’s specifications. You can have an electrician assess your wiring and advise on the best course of action.

  • Extra features

Besides the primary considerations, you can also weigh the benefits of some nice-to-have features. These functions can offer more convenience and operational efficiency.

Most modern models come with remote control. They also have additional operating modes. For instance, window air conditioners with heat will allow you to toggle to heat mode in the winter. Meanwhile, units with Fan Only mode can help you improve air circulation efficiently.

At the very least, a window mounted air conditioner will come with basic air filtration to remove large particles from incoming air. Filters get more advanced as you climb the price pole. Some premium models can even remove odors, smoke, mosquitoes, and microbes. 

Window AC for large room with adjustable louvers

High-end ACs like the Friedrich Chill EP18G33B mentioned above have adjustable louvers for multi-directional airflow. This feature enables you to customize the air circulation in your space. 

Final Words

We do not doubt that you will find this post useful when picking out your future window air conditioner. Follow the title links on our recommended units to learn more about them. You can also use our buying guide above to get as close to the right system as possible.

Remember, indoor air quality can directly impact your comfort and health. You owe it to yourself and your loved ones to invest in reliable air conditioning.
