🛠 What You’ll Need

  • Portable air conditioner unit

  • Window vent kit (usually included)

  • Screwdriver (if needed)

  • Power outlet nearby

  • Towel or weather stripping (optional, for sealing)

🔧 Step-by-Step Guide to Setup

1. Unbox and Inspect

Carefully remove the unit from the packaging and check for any visible damage. Verify that all parts (like the hose and window kit) are included.

💡 Tip: Let your air conditioner sit upright for at least 2 hours before turning it on, especially if it was transported horizontally. This allows the refrigerant to settle properly.

2. Choose the Right Location

Pick a spot near a window and a power outlet. Make sure:

  • There’s at least 20 inches of clearance around the unit

  • The exhaust hose can reach the window easily

  • The drain plug is accessible (some models collect condensation)

Avoid placing it near curtains or furniture that could block airflow.

3. Install the Window Vent Kit

Most portable air conditioners come with a window kit for venting hot air. Here's how to set it up:

  1. Adjust the window panel to fit your window size.

  2. Insert the panel and close the window to hold it in place.

  3. Attach the exhaust hose to the back of the unit.

  4. Connect the other end to the window panel opening.

Seal any gaps with weather stripping for better efficiency.

4. Plug In and Power Up

Plug your unit into a grounded outlet. Turn it on and select your desired settings (cooling mode, fan speed, temperature).

Some advanced models have remote controls and smartphone connectivity — explore our smart home cooling solutions for more options.

5. Drain the Condensation (Optional)

Some units have self-evaporating systems. Others may need occasional draining. If you notice the unit shutting off or a “full tank” light, locate the drain plug and empty the water into a pan or through a drain hose.

🧽 Maintenance Tips for Best Performance

  • Clean the air filter every 2–4 weeks

  • Check the exhaust hose for obstructions

  • Store properly in winter or when not in use
