Mini Compact Window Air Conditioner Buying Guide

Does a Window AC Unit Need to be in a Window?

Yes, window units are particularly designed to be installed in a window. They eject hot air and water as byproducts, as a result of the cooling, and there are no safe ways to redirect them if you plan to install the unit in any other place in your room.

The main differences between the two types of ACs are installation and venting. Window ACs don’t require permanent installation and can fit through a window. On the other hand, wall air conditioners are built into the wall, making them ideal for rooms without windows or for people who prefer to have their windows unoccupied for air.

Wall ACs usually just vent hot air through the outer of the unit, on the contrary, window air conditioners expel air from the sides and back. This is why; window and wall units are not interchangeable, even if their dimensions are the same. Overheating can occur, if a window unit vents out its side and wall blocks the vents. Only a selected window AC models can be installed through a wall, provided that have a slide-out chassis wall sleeve.

Are Window Air Conditioners Safe?

Yes, window air conditioners are completely safe. Although, there are a few myths about window ACs, for instance, that they produce carbon monoxide that is harmful to our health. However, this is not true. Carbon monoxide is only produced while burning and since your AC unit is not burning anything you are not breathing anything harmful.

In spite of this fact, window air conditioners are safe, it is mandatory to take safety measures while installing and operating the AC. Make sure that the installation is done well. You can use brackets for additional safety to ensure your unit is securely installed.

Moreover, clean your filters, evaporator coils, and take other maintenance steps to ensure clean and safe operation. It is recommended to call a professional HVAC technician to inspect your unit at least twice a year.

How do I Calculate What Size Window Air Conditioner I need?

Before making a buying decision, it is important first to carry out your research and analyze what size of air conditioner you need to buy. An impulsive or spontaneous buying decision can lead to buying a less or more powerful unit than you need, thus, wasting your hard-earned money. We have explained below, the procedure to properly size a window air conditioner.

Type of Installation

First things first, you must analyze what kind of installation you are looking for when choosing your window air conditioner. Some AC units are designed for standard window sizes, while others are designed to be installed on a custom-created wall space with the help of special mounting hardware. 

There are two types of installations:

  • Window

Make sure you are keeping the dimensions of your window in mind before choosing your AC. Window mounted air conditioners are, sometimes, only designed to be fitted into a sliding or casement window. So if you have standard double-hung windows, you need to reconsider your decision.

  • Wall

If you are looking for an AC, especially for wall installation, keep in mind, not every window AC model is built for wall installations. Carefully note down the specifications of the AC unit and check if your wall has enough space to accommodate it. 

Calculating the Cooling Power

Getting the right-sized air conditioner is important because a low cooling power AC will not be sufficient to cool your room, and an AC with a high cooling power will freeze your room. Both situations can make you very uncomfortable and put your hard-earned money down the drain.

Air conditioners use BTU for determining the cooling power of the AC. The first step is to measure the dimensions of your room. To calculate the square feet of your room, simply multiply the width and the length.

The next step is calculating the BTU, for that divide the square feet with 0.05. Here is a list of general sizing that you can use to determine the BTU required for the size of your room.

 General Sizing

100 to 300 square feet = 5,000 to 6,500 Btu

250 to 400 square feet = 7,000 to 8,500 Btu

350 to 650 square feet = 9,800 to 12,500 Btu

 Electrical Outlet Inspection

Last, but not least, inspect the electrical outlet near the place you are going to install the AC. Window air conditioners come in 115 – 240 volts models. Each requires a different outlet, so it is important to determine this before purchasing the unit.

How to Select the Right Compact Window Air Conditioner for Your Room

Finding the right features when buying a compact window air conditioner is essential as you need to look for the one that perfectly suits your needs. We have listed below some important features to help you find the best compact window air conditioner for your room.

Energy-Star Compliant

When you’re investing your money on an air conditioner, why not buy one that is energy-efficient and can save your hard-earned money on utility bills. Make sure to check the energy-efficient ratio (EER) of an Energy Star-compliant window air conditioner to check for its efficiency. The higher the EER, the more energy you can save.

24-Hour On/Off timer

Talking about saving energy and money on bills, this is one feature that cannot be ignored. The 24-hour on/off timer enables you to operate your air conditioner according to your schedule. This feature is extremely useful, especially on scorching summer days when you want to come home to a cool room after a long day at work. If you want even more options for energy saving, look for the Eco mode when searching for a narrow window air conditioner for your room.

Anti-Corrosion Body

The body or the exterior of the air conditioner is as vital as its interior features. You want your AC to be durable and able to withstand all weather conditions. Therefore, look for an anti-corrosionn body to ensure a long life span of your air conditioner.

Dehumidifier

People with dust allergies should always look for this feature when looking for an air conditioner as the dehumidifier feature helps remove any dust particles, foul odor, and humidity from the room. 

3-Fan Mode

Air conditioners with fan adjustments provide you with the flexibility to change the temperature of the room. The 3-fan modes offer three speeds, allowing you to set the temperature according to your needs. In addition to this, the air direction control is a multi-directional feature that ensures an efficient airflow to make your room cold fast. 

AC/Heater combination

The importance of this feature cannot be emphasized enough. Having an AC/Heater combo allows you to use your air conditioner for both summer and winter seasons. What better than getting two appliances in the price of one?

Filter Alert

The filters of your air conditioner are responsible for purifying the air in your room. Checking them repeatedly can be quite a hassle. The filter alert feature of your AC unit will notify you when your filters need cleaning or replacement. 

Auto Restart

Power outages can be unpredictable and can occur at any time during the day or night. The auto-restart feature allows your AC to restore its previous settings before shutting off. This feature can be useful, especially during the night while you’re sleeping since you won’t have to disturb your sleep for turning on the AC and maintain its settings in the middle of the night.

Ultra-Quiet Operation

There’s no point in buying an air conditioner that can’t provide you with the comfort you were looking for. An air conditioner that makes loud rattling sounds can make relaxing nearly impossible. Even if your system cools your room efficiently, the loud sounds can be very annoying and distracting, especially when you’re sleeping.

LED Remote

An LED remote allows you to set the temperature from any spot in your room without having to get up and disrupt your comfort.
