10 Steps Aircon Installment

1. Assess Your Space and Needs

Before installation begins, evaluate your home’s cooling requirements. Consider factors like room size, insulation quality, and existing ductwork (for central AC systems). For split systems, identify ideal locations for indoor and outdoor units, ensuring the outdoor unit has unobstructed airflow and the indoor unit avoids direct sunlight or heat sources.

2. Prepare the Installation Site

Clear the area around the installation zone of debris, furniture, or obstructions. For window ACs, ensure the window frame is sturdy and has access to an electrical outlet. For split systems, verify that the wall can support the indoor unit’s weight and drill a hole for refrigerant lines, angled downward for drainage.

3. Mount the Indoor Unit

Secure the mounting plate to the wall using anchors and screws, ensuring it’s level and stable. For split systems, connect the indoor unit to the plate, double-checking alignment with a spirit level. Avoid bending or twisting refrigerant lines during installation to prevent leaks.

4. Install the Outdoor Unit

Place the outdoor unit on a flat, stable surface (e.g., a concrete pad) and secure it with brackets to prevent vibrations. Ensure adequate clearance around the unit for airflow and heat dissipation.

5. Connect Refrigerant Lines and Wiring

Thread refrigerant lines through the drilled hole, securing them with hangers every 4–6 feet to avoid kinks. Connect the lines to the indoor and outdoor units, brazing or welding joints for leak-proof seals. For electrical wiring, follow manufacturer guidelines to link the units and thermostat.

6. Seal Gaps and Insulate

For window ACs, use foam insulation or weatherstripping to seal gaps between the unit and the window frame, enhancing energy efficiency. For split systems, ensure all connections are tightly sealed to prevent refrigerant leaks.

7. Test the System

Power on the AC and check for unusual noises, leaks, or uneven airflow. Verify cooling performance by adjusting settings and monitoring temperature changes.

8. Dispose of Old Units Responsibly

If replacing an existing AC, safely remove refrigerants and recycle the old unit to avoid environmental harm. Partner with professionals for hazardous material handling.

9. Schedule Maintenance

Regular upkeep extends your AC’s lifespan. Book annual tune-ups with a certified aircon installer to clean filters, inspect refrigerant levels, and address wear-and-tear issues early.

10. Opt for Professional Guidance

While DIY installation is possible, complex systems (e.g., central AC) require expertise. Trust a licensed aircon installer to handle refrigerant handling, electrical work, and warranty compliance for a stress-free, easy install aircon experience.
