| 150 – 250 | 6,000 – 8,000 |
| 250 – 350 | 8,000 – 10,000 |
| 350 – 450 | 10,000 – 12,000 |

Prepare The Window Area
Start by cleaning the window framethoroughly. Remove dust, dirt, and old paint chips. A clean surface helps the air conditioner fit snugly and prevents damage.
Check the window frame for any signs of damage. Look for cracks, rotting wood, or loose parts. Fix any issues before installing the air conditioner to ensure safety and stability.
Install The Support Brackets
Find the best spots on the window frame to hold the brackets. These spots must be strong and level.
Mark these spots carefully to ensure the air conditioner stays steady.
Use screws that fit the brackets tightly. This stops any wobbling or slipping.
Check the brackets after fixing them. They should not move or bend under pressure.
- Pick brackets made of strong metal.
- Place brackets under the air conditioner’s base.
- Use a level tool to keep brackets straight.
- Tighten screws firmly but avoid over-tightening.
- Test stability by gently pushing the air conditioner.
Position The Air Conditioner
Lift the air conditionerwith care. Use both hands to hold it steady. Avoid tilting it too much to prevent damage.
Place the unit gently into the window frame. Make sure it fits snugly without forcing it.
Check the levelof the air conditioner. A slight tilt outward helps water drain properly.
Use a small level tool or a smartphone app to ensure it is balanced. Adjust with shims or foam pads if needed.
- Lift carefully with two people if the unit is heavy.
- Place the unit so it rests securely on the window sill.
- Ensure a small outward tilt for water drainage.
- Use shims for perfect leveling and support.

Seal Gaps And Insulate
Weather stripping helps close small gaps around the air conditioner. It stops air leaks and keeps the room cool. This material is easy to cut and stick. Choose foam or rubber types for better sealing. Press it firmly along the window frame edges. Check for any spaces after applying. Replace worn or damaged strips to maintain a tight seal.
Foam sealant fills bigger gaps and cracks around the unit. It expands and hardens to block air and moisture. Use a spray foam that is safe for windows. Apply carefully to avoid excess foam. Trim any extra foam after drying to keep a neat look. This method improves insulation and reduces noise.
Secure The Unit With Screws
Attach the side panels firmly to the air conditioner unit. This helps keep the unit stable and prevents gaps around the window. Use screws designed for metal or plastic, depending on your unit’s material. Make sure the panels fit snugly against the window frame.
Fasten the unit to the window frame using screws. This step stops the air conditioner from moving or falling out. Check that the screws are tight but not too tight to avoid damage. Secure the sides and bottom of the unit for the best hold.

Check Stability And Safety
Ensure the air conditioner fits securely in the window frame. Gently push and pull the unit to check for any movement. The unit should feel stable and not wobble. If it moves, adjust the brackets or supports until it is steady.
Inspect the electrical connections carefully. Make sure the power cord is not frayed or damaged. The plug should fit snugly into the outletwithout any sparks or loose contacts. Avoid using extension cords; plug the unit directly into a grounded outlet for safety.
Maintain Your Window Air Conditioner
Keep the air conditioner clean to ensure it works well. Dust and dirt can block airflow and reduce cooling power.
Use a soft cloth or brush to clean the filters every month. Wash them with water and let them dry completely before putting back.
Clean the coils gently to remove dirt. This helps the unit cool better and saves energy.
Check the window seal and tighten any loose parts. This stops cold air from escaping and keeps bugs out.
