Are you in need of a cooling system for your home but don't want to invest in expensive and complicated installations? Look no further! Vertical window air conditioners are the perfect alternative for those who have sliding windows or doors. In this guide, we will walk you through everything you need to know about these ACs and help you find the best one for your home.

Sorting out the Terminology

Before we dive in, let's clear up any confusion about the terminology. You might come across terms like "casement window AC," "sliding window AC," or "crank window AC." Don't be thrown off by the different names; they all refer to the same type of AC designed for vertical windows. For the purpose of this guide, we will stick to calling them vertical window air conditioners.

Differences between Regular and Vertical Window Air Conditioners

Regular and vertical window air conditioners offer the same performance and features, but they cannot be used interchangeably. Regular window ACs are designed for single-hung or double-hung windows and must be installed horizontally. Placing them in a vertical position can cause damage to the unit. Vertical window ACs, on the other hand, are specifically made for sliding windows and must be installed vertically.

Cooling Capacity and Coverage Area

When it comes to output and coverage, vertical window air conditioners have their limitations. Most models offer around 1 ton of cooling power and can supply 8,000 to 10,000 BTUs. This makes them suitable for cooling a single room or an area of up to 450 sq/ft. Keep in mind that the coverage range may vary depending on factors like insulation and climate.

Noise Level

Rest assured, vertical window air conditioners are not excessively noisy. Most models produce less than 60dB of noise, which is similar to a bathroom exhaust fan or a microwave. The noise level may slightly increase for the part of the unit facing outside. It's always a good idea to check the manufacturer's specifications for noise levels to ensure you choose a model that won't disrupt your sleep or daily activities.

Installation Requirements

Before installing a vertical window AC, it's essential to check the dimensions of both the unit and your window. These ACs are typically around 15 inches wide, making them suitable for narrower windows. You may need to purchase an installation kit separately, which usually includes a foam filler panel to cover the gap between the window frame and the AC. Additionally, creating a stable platform for the AC and ensuring proper drainage are important for installation.

Factors to Consider When Choosing a Vertical Window AC

While there may not be a wide variety of options available for vertical window air conditioners, there are still a few key factors to consider:

Window Type and Size

Make sure the AC is compatible with your window type and size. Vertical window ACs are designed for sliding windows, which are narrower than single-hung or double-hung windows. Casement window ACs typically have a width of 14 to 15 inches, but it's always best to check the exact dimensions of the model you choose.

Installation Kit

Check if the AC comes with an installation kit or if you need to purchase one separately. The kit should include a foam filler panel to close the gap in the window and a support platform to hold the AC securely.

Energy Efficiency Ratings

Consider the energy efficiency of the AC by looking at its EER (Energy Efficiency Ratio) and SEER (Seasonal Energy Efficiency Ratio) ratings. Models with higher ratings consume less electricity, resulting in lower utility bills. Look for models that are Energy Star certified for even greater energy efficiency.

Cost and Warranty

Compare the prices of different vertical window ACs, keeping in mind that they generally range from $400 to $600. Consider the coverage area and output capacity when evaluating the cost. Most brands offer a one-year warranty that covers labor and replacement of broken parts. Some manufacturers also provide 5-year limited warranties under specific conditions.

Advantages and Disadvantages of Vertical Window Air Conditioners

Before making a final decision, let's quickly go over the pros and cons of vertical window air conditioners:

Advantages

  1. Easy Installation: Vertical window ACs can be installed by homeowners without professional help, thanks to their straightforward installation process and included installation kits.

  2. Air Humidity Control: These ACs not only regulate room temperature but also control air humidity, ensuring a comfortable indoor environment. They have a built-in drain to dispose of condensed water automatically.

  3. Reasonable Pricing: Vertical window ACs are more affordable than other cooling systems, making them a cost-effective option. Installation costs are minimal since you can install them yourself.

Disadvantages

  1. Limited Portability: These ACs are heavy, making it impractical to move them between rooms frequently. Additionally, the support platform needs to be moved each time you want to change the window.

Now that you have a good understanding of vertical window air conditioners, let's explore the top five models available on the market.
