HOMCOM Portable Air Conditioners provide an effective cooling solution for single rooms, helping you create a comfortable indoor environment. In addition to cooling, they also offer ventilation and dehumidifying functions to circulate air and remove excess moisture.

Step-by-Step Installation Instructions
Attaching the Exhaust Hose and Window Kit
To cool effectively, your portable AC must release hot air outdoors. The exhaust hose and window kit make this possible by venting air through a secure window opening. Proper setup ensures maximum efficiency and prevents heat from leaking back into the room. Follow these steps for proper setup:
- Connect one end of the exhaust hose to the hose connector on the unit.
- Attach the window kit adapter to the other end of the hose.
- Place the adjustable window kit into your open window frame (vertical or horizontal).
- Extend the kit until it fits snugly, then insert the hose adapter into the window kit opening.
- Close the window firmly against the kit to hold it in place.
- Seal any small gaps with duct tape or weatherstripping for maximum efficiency.
- Attach the hose connector to the exhaust outlet on the AC unit.
Important: Avoid extending or bending the hose too much. A long or twisted hose reduces airflow and can cause the unit to shut down.
Positioning the Unit Correctly
Now that the exhaust system is in place, move the unit into its final position.
- Keep it on a firm, level surface.
- Place it within easy reach of a power outlet.
- Leave space behind and beside the unit for proper ventilation.
Pro Tip: Use casters to reposition the unit if needed. Just be careful when moving it if the water tank has collected water, always empty it before transporting.
Choosing the Right Location for Setup
Your portable AC’s performance depends heavily on where you place it. Proper location ensures efficient cooling and prevents overheating or system damage.
Placement Do’s and Don’ts:
- Do keep at least 28 inches (70 cm) of space around the unit for airflow.
- Do place it near a grounded power outlet.
- Do position it where the exhaust hose can reach a window.
- Don’t place it in direct sunlight, which can force the compressor to work harder.
- Don’t set it near stoves, heaters, or other appliances that generate heat.
- Don’t block the air inlet or outlet with curtains, furniture, or walls.

FAQs
1. Can I use the HOMCOM Portable Air Conditioner without a window?
Yes, but the hot air must be vented somewhere. If you don’t have a window, you can vent through a sliding door, ceiling vent, or even a wall opening with the right adapter.
2. Does the portable AC need to be drained manually?
It depends on the humidity level in your room. Some models have self-evaporation, but in very humid environments, you may need to empty the water tank or connect a continuous drain hose.
3. Can I use the portable air conditioner in a camper, RV, or mobile home?
Yes, if there’s a suitable outlet and place to vent hot air outside. Keep in mind that small enclosed areas may require frequent drainage.
4. What should I do before storing the portable AC for the winter?
Drain all water from the tank, clean the filters, wipe down the exterior, and store it in a dry place with the exhaust hose and accessories packed neatly.
