Deep Chill: The Basement Air Conditioner Guide

basement air conditioners

Whether it’s a rec room, extra living room, or storage space, basements can be a great place in the house to hang out. However, when it comes to cooling during different times of the year, it can be a little bit tricky. If your basement was not already equipped with the proper setup when it was built, you will have to take the time to install a basement air conditioner that will help you cool it effectively and efficiently.

In this article, we’ll discuss your options for cooling your basement, and the different types of basement air conditioners.

Why Basement Cooling is Important

Basements are unique spaces that often face challenges like higher humidity levels, lower temperatures, and limited ventilation. While they can stay cooler than the rest of the house in summer, they can also become stuffy, damp, or too cold, making them uncomfortable or even unhealthy. 

Cooling a basement effectively can improve comfort, reduce humidity, and prevent mold growth. This is particularly important if you use the basement as a workspace, recreational area, or extended living space. Even if you only use it to store items, an improperly cooled basement can lead to property damage caused by excess humidity.

Choosing a Basement Air Conditioner: What to Consider

1. Size of the Basement

The basement’s size will dictate the capacity of the air conditioner needed to cool it. This is measured in BTUs (British Thermal Units). An undersized unit will struggle to cool the space, while an oversized unit may cool too quickly without properly dehumidifying.

To determine the BTU needed for your basement, measure its dimensions and use our handy Air Conditioner BTU calculator.

2. Installation Requirements

Some units, like central air or mini splits, require professional installation, while some models like window ACs require a window for placement. Also, consider if you have the necessary outlets or wiring for your chosen placement location.

3. Energy Efficiency

If the basement is regularly used and thus needs regular cooling, energy efficiency is a key consideration to save on utility bills. 

Look for units with high SEER (Seasonal Energy Efficiency Ratio) or EER (Energy Efficiency Ratio) ratings. These measure the AC’s energy efficiency, with a higher rating indicating a more efficient unit.

Additionally, an EnergyStar label certifies that the AC is more efficient than its non-labeled counterparts. This label is awarded to models that meet stringent efficiency standards set by the US Environmental Protection Agency and Department of Energy.

4. Aesthetics and Space

Consider how the unit will fit into your basement’s design. Mini splits have a more modern look but require wall space. Portable units are flexible and can be moved, but take up floor space.

5. Ventilation Options

Venting is crucial for portable, window, and through-the-wall AC units. For these models, make sure there’s a way to vent hot air outside, whether through a window, wall, or ceiling. 

6. Humidity Control

Basements are prone to high humidity, so look for units with strong dehumidification features. This is especially important in damp climates or if the basement has had moisture issues.

7. Noise Level

If the basement will be used as a living area or bedroom, noise will be an important factor. Mini splits and central air systems tend to be quieter, while portable and window units can be noisier.

Types of Basement Air Conditioners

1. Ductless Mini Split

Mini splits are efficient cooling systems. They consist of an indoor unit mounted on the wall and an outdoor compressor unit. They do not require ductwork and are highly efficient.

Pros:

Efficiency: Highly energy-efficient with the ability to cool large or multiple rooms.

Quiet Operation: The compressor is outside, so the indoor unit is very quiet.

Zoned Cooling: Allows for targeted cooling in specific areas.

Dehumidification: Excellent at reducing humidity in the basement.

Cons:

Cost: Higher upfront cost compared to other types.

Installation: Requires professional installation, which can add to the cost.

Aesthetic Impact: The indoor unit is visible on the wall, which might not suit all designs.

2. Window Air Conditioners

As the name suggests, these are installed in a window, with the bulk of the unit outside and the controls and cooling vents inside.

Pros:

Efficiency: Generally more energy-efficient than portable units.

Space-Saving: Doesn’t take up floor space in the room.

Cons:

Installation: Requires a window that can accommodate the unit, which may be an issue in some basements.

Light Blockage: Blocks natural light from the window where it’s installed.

Permanent Fixture: Not easily moved once installed.

6. Central Air Conditioning

An HVAC system that cools the entire home, including the basement, through ductwork.

Pros:

Whole-Home Cooling: Cools the entire house, including the basement, uniformly.

Efficiency: Can be highly efficient, especially with modern systems and zoning options.

Aesthetic: No visible units inside the basement, as all components are hidden.

Cons:

Cost: High installation cost, particularly if retrofitting into a home without existing ductwork. Many homes that already have central air do not have a register in the basement. While a register may be able to be added, it can affect the performance of the rest of the system if it was not rated for it.

Energy Usage: Cooling the entire home can be energy-intensive, especially if the basement is the primary focus.

Complexity: Requires professional installation and regular maintenance.

  3. I wish I could figure out how to cook my basement sewing room. My machine needs to be along the window, with no room for an in window unit or vents from a few feet away. I don’t think it is worth cutting a hole in the wall. and here in Atlanta, I don’t want to add more moisture to the already humid air. Fans just blow my fabric and pattern pieces to Kingdom Come. I guess I don’t have much of a choice, as we have already put about $60K into the house this spring. Oh well.

    If anyone has any ideas, please share them!
