Portable Air Conditioners

Buying Guides | Portable Air Conditioners

Portable air conditioners are versatile, freestanding units that provide cooling wherever you need it most. They are ideal for spaces where traditional air conditioning solutions, like window units or central AC, are impractical. Portable air conditioners are easy to set up, require minimal installation, and can be moved from room to room, making them a convenient solution for renters, small apartments, offices, or even supplemental cooling in larger homes.

This comprehensive guide will help you choose the best portable air conditioner for your space by explaining key features, how to determine the right cooling capacity, and what to look for when buying one.

1. What Is a Portable Air Conditioner?

A portable air conditioner is a self-contained unit that can cool a room by pulling warm air from the space, cooling it, and expelling the heat outside through an exhaust hose. These units typically have wheels, making them easy to move from room to room. Portable ACs are vented through a window or a sliding door using an exhaust hose, which removes the hot air from the room.

Pros:

        • No permanent installation is required.
        • Easily moved between rooms.
        • Ideal for renters or spaces without access to central air.

Cons:

        • It can be noisy.
        • Less efficient than window or central units.
        • Requires venting through a window or door.

 

2. Types of Portable Air Conditioners

a. Single-Hose Portable Air Conditioners

Single-hose portable air conditioners have one exhaust hose to expel hot air from the room. These are the most common and affordable types but may struggle with larger rooms since they have to work harder to cool the space.

Pros:

            • Easy to install.
            • Generally, more affordable.

Cons:

            • Less efficient in larger spaces due to air circulation issues.
            • It can create negative pressure in the room, drawing in warm air from other areas.

b. Dual-Hose Portable Air Conditioners

Dual-hose units have two hoses: one for pulling in air from outside to cool the unit and another for expelling warm air back outside. This system prevents negative pressure and is more energy-efficient, especially in larger rooms.

Pros:

            • More efficient cooling, especially in large spaces.
            • Less strain on the unit due to improved air circulation.

Cons:

            • Slightly more expensive.
            • Installation is more involved due to the dual hose system.

c. Evaporative Coolers

These are technically not air conditioners but function similarly in dry climates by using water evaporation to cool the air. They are highly energy-efficient but less effective in humid areas.

Pros:

            • Low energy consumption.
            • Doesn’t require venting.

Cons:

            • Only effective in dry climates.
            • Not as powerful as traditional AC units.

 

3. How to Choose the Right Portable Air Conditioner

a. Cooling Capacity (BTUs)

The cooling capacity of portable air conditioners is measured in BTUs (British Thermal Units). This rating determines how much heat the unit can remove from a room per hour. Choosing the correct BTU rating ensures that your space is cooled efficiently.

Use the chart below to determine the BTU rating you need based on the size of your room:

              • 100 – 250 sq. ft.: 5,000 – 8,000 BTUs
              • 250 – 400 sq. ft.: 8,000 – 10,000 BTUs
              • 400 – 600 sq. ft.: 10,000 – 14,000 BTUs
              • 600 – 800 sq. ft.: 14,000 – 16,000 BTUs

Important Factors:

              • Sun Exposure: Add 10% more BTUs if the room gets a lot of direct sunlight.
              • Ceiling Height: Increase BTUs if your ceilings are higher than the standard 8 feet.
              • Room Usage: For kitchens or spaces with multiple electronics, add extra BTUs to account for the additional heat load.

b. Venting Options

Portable air conditioners require venting to expel hot air, usually through a window. Most units come with an exhaust hose and window kit that fits standard windows.

Key Venting Considerations:

            • Window Type: Ensure your window is compatible with the included vent kit. Most kits are designed for sliding or double-hung windows.
            • Exhaust Hose Length: Consider the length of the exhaust hose, especially if you have high windows or need to place the unit farther from the window.

c. Energy Efficiency

Look for Energy Star-certified portable air conditioners, which use up to 10% less energy than standard units. Energy-efficient models help lower electricity bills while reducing the environmental impact.

              • EER (Energy Efficiency Ratio): This rating measures the cooling output (BTUs) relative to power consumption. A higher EER means better energy efficiency.

d. Noise Level

Portable air conditioners can be noisy due to the compressor and fan. Look for units with a noise level under 55 decibels (dB) for quieter operation, especially for bedrooms or office spaces.

e. Heating Option

Many portable air conditioners come with a heating function, allowing them to work as space heaters in winter. This is particularly useful for year-round climate control.

 

4. Key Features to Consider

a. Dehumidification

Most portable air conditioners also function as dehumidifiers, removing moisture from the air while cooling. This feature is especially useful in humid climates, helping reduce the sticky, heavy feeling of hot, moist air.

            • Pint Capacity: Look for units that list how many pints of moisture they can remove from the air per day.

b. Programmable Timer

A 24-hour programmable timer allows you to set the air conditioner to turn on or off at specific times, saving energy and ensuring the room is cool when you need it.

c. Remote Control and Smart Features

Many portable air conditioners come with a remote control, allowing you to adjust the settings from across the room. For added convenience, some models feature Wi-Fi connectivity for control via smartphone apps or integration with smart home systems like Alexa or Google Assistant.

d. Multiple Fan Speeds

Most portable ACs have multiple fan speed settings to adjust airflow to your comfort level. Higher fan speeds cool rooms faster, while lower speeds provide quieter operation.

e. Air Filtration

Some portable air conditioners come with built-in air filters or air purifiers, which remove dust, pollen, and other allergens from the air. This feature is especially useful for people with allergies or respiratory conditions.

 

5. Installation and Maintenance

a. Easy Setup

Portable air conditioners are known for their easy installation. Most units come with an exhaust hose and window venting kit that can be set up without professional help.

Basic Installation Steps:

            1. Position the Unit: Place the portable air conditioner near a window and a power outlet.
            2. Install the Exhaust Hose: Attach the exhaust hose to the back of the unit and connect it to the window vent kit.
            3. Secure the Window Kit: Fit the window kit into the window, securing it to prevent hot air from leaking back inside.
            4. Plug in and Turn On: Plug the unit into a nearby electrical outlet, and it’s ready to use.

b. Water Drainage

Some portable AC units use self-evaporation to remove condensation, meaning you won’t have to empty the water tank frequently. However, in humid conditions, you may need to manually drain the water tank or connect a drain hose to manage excess water.

Drainage Methods:

            • Self-Evaporating Models: Evaporate moisture automatically.
            • Manual Drain Models: Require you to empty the water tank periodically.
            • Continuous Drainage Models: Connect a hose for continuous drainage.
