Large Window Air Conditioner Buying Guide

A window air conditioner is a long-term investment, so it makes sense to want to make the right decision when you go shopping. And that is what this section is all about, especially if you’re a new buyer.

All window air conditioner manufacturers promise a lot of things to buyers and advertise their products as the best. This makes it difficult sometimes to make the right choice.

However, we have listed some of the basic and important things you have to consider when choosing a window air conditioner for your home. Keep in mind that other extra features improve efficiency and convenience when using an air conditioning system.

However, if you disregard the basic things, then you won’t get the best out of your unit. If you’re not sure about the size of your window, you can also check air conditioners for small window opening.

Before we delve into these factors, why is a window air conditioner important?

Benefits of Window Air Conditioners

There are two major reasons why you need to choose window air conditioners:

1. Budget-friendly

Window air conditioners are an affordable yet reliable option for cooling your house. Installing a central air condition system is a very costly investment, and can prove to be very heavy on the pocket in terms of operation and maintenance costs. 

People that go for a window unit usually want only one room of their house to be cool at a time. It is an energy-efficient option if you want to save money on your cooling bills.

Depending on your budget, you can find cheap window air conditioners under $200 or go for high-end units over $500.

2. Easy Installation

While installation differs from one model to another, a window AC unit is pretty easy to install, and you don’t need an HVAC technician to do it for you. Most manufacturers even include an installation manual to help people who don’t consider themselves handy. All they have to do is follow the step-by-step directions.

Moreover, it is easy to uninstall, which makes it ideal for people in a rented property. They can easily take their window air conditioning unit with them when they plan to move out without any hassle. 

3. Compact

Window air conditioning units are ideal for small rooms as they can cool the room quickly and effectively. The compact size of a window unit does not make a room look cramped or take up your floor space, which is a huge advantage if you live in a tiny house.

Things to Consider when Choosing the Best Window Air Conditioner for Large Room

Now that you know the advantages of a window air conditioner let’s walk you through the factors you have to consider before making your purchase.

1. Cooling Capacity

This is the most important thing you have to consider when choosing an air conditioner. You should calculate the area of your room where you want your air conditioner to be installed. The BTU, which is the unit for measurement of the cooling power per hour, is specified for every AC model. You can analyze the BTU that would be required for your space. The BTU can range from 5,000 to 24,000, depending on the size of your room.

2. Installation

You must consider what kind of installation you are looking for when choosing a window air conditioner for your room. Some AC units are designed for the standard window sizes, while others are designed to be installed in a custom-created wall space with the help of specialized mounting hardware.  If you have vertical or horizontal windows, you can also choose casement window air conditioners.

There are two kinds of installations:

  • Window: Make sure you are keeping the dimensions of your window in mind before choosing your AC. If you have a tiny window, don’t panic as your AC unit can still be installed with the help of the installation kit.
  • Wall: Not every window AC model is built for wall installations, so choose your AC keeping that in mind. Carefully note down the specifications of the AC unit and check if your wall has enough space to accommodate it. The best option is usually to select a wall-mounted air conditioner.

3. Electrical outlet requirement

There are a few window air conditioners that require a 230-volt electrical outlet and special plugs to operate. Don’t forget to go through this important factor that most people ignore while choosing their window ACs.

4. Noise

No matter how well your window AC functions, if it is loud enough to disrupt your daily routine or disturb your sleep, it will not prove to be a reliable unit. However, keep in mind that most air conditioners for large rooms are a little noisy because of the capacity they hold. 

What we recommend is to check the decibel rating and choose the lowest figure. If the figure is below 55 decibels, then it won’t be too loud. Avoid any unit that has a decibel rating over 60; it will be too loud, you won’t be able to concentrate.

5. Energy Efficiency

Look for an Energy Star-compliant air conditioner model. The energy-efficiency ratio (EER) will also give you an idea of how efficient the air conditioner is. The higher the EER, the more energy it can save. A 24-hour on/off timer is also a feature to look for if you are searching for an energy-efficiency AC. By maintaining the temperature, it will save not only your energy use but also your precious money.

6. Exterior

The exterior of a large air conditioner is as important as its interior features. As mentioned above, an AC is a long-term investment, so you want to make sure it lasts for a long time. An anti-corrosion body will ensure a long life span of your air conditioner. 

Features to Look for in the Best Window Air Conditioner for Large Room

Some features are intended to improve efficiency and convenience when using a window air conditioner. Here are some of those features

  • Dehumidifier: This is the best feature for people with allergies. It helps remove excess moisture from your room, purifies the air, and removes bad odor. 
  • Eco-Mode: Eco mode is an important feature if you are looking for an energy-saving air conditioner that provides you with low utility bills. 
  • Filter Alert: Nobody likes to check the filters of their AC from time to time. The filter alert feature notifies you when you need to clean or replace your filters.
  • 24-Hour On/Off timer: This feature enables your air conditioner to work around your custom schedule. If you want to come home to a cool room after a long day at work, time your air conditioner as per your schedule. 
  • AC/Heater combination: It’s always a delight to get two things for the price of one. Have an AC/Heater combo makes a unit versatile for both seasons.
  • LED Remote: The LED remote helps you to see, set, and maintain the temperature of the AC from anywhere in the room. 
  • Auto Restart: In case of a power outage, the operation of your AC gets interrupted. The auto-restart feature enables your Ac to restore its previous settings before turning off.
  • Fan Speed Adjustments: Most air conditioning units come with a three fan mode these days; it allows you to change the cooling with flexibility. 
  • Air Direction Control: The air direction control makes your AC more efficient and cools the room quickly. If the AC has auto swing louvers, feature, your room will get cold quickly.
  • Ultra-Quiet Operation: Your window air conditioning system should not only be efficient and cool the room fast, but it should not be noisy as well. Sometimes, ACs make a loud, rattling sound that is very unpleasant to the ears. It can be very distracting and annoying and can mess up your sleep schedule.

These are some of the features that are instrumental in making a buying decision. Remember, the requirements could differ from person to person, so analyze your needs carefully before making your final decision.
