1. Airflow Issues: Weak or uneven airflow from vents can indicate issues with ductwork, filters, or system balance.

2. Warm Air Blowing: If your AC is blowing warm air, it could be due to refrigerant leaks or thermostat issues.

3. Unusual Noises: Grinding, squealing, or scraping noises could mean a belt slipping or metal parts grinding.

4. High Energy Bills: A sudden spike in bills means your AC might be struggling due to leaks or dirty coils.

5. Water Leaks: Pooling water often signals a clogged drain line or refrigerant leak.

6. Increased Humidity: Sticky indoor air means poor dehumidification — often a system issue.

7. Bad Odors: Foul smells can mean mold inside your unit or electrical faults.

8. System Age: If it’s 10+ years old, replacement may be more efficient.

9. Short Cycling: Frequent on-off cycles hurt efficiency and components.

10. Frozen Coils: Dirty filters or low refrigerant can freeze coils and block airflow.

What to Do Next: If you notice these signs, call a professional AC technician immediately for inspection and repair.

• 𝗖𝗹𝗲𝗮𝗻 𝗙𝗶𝗹𝘁𝗲𝗿𝘀 𝗥𝗲𝗴𝘂𝗹𝗮𝗿𝗹𝘆: Clean your AC filters regularly to improve airflow and reduce energy consumption.
• 𝗜𝗺𝗽𝗿𝗼𝘃𝗲𝗱 𝗦𝘆𝘀𝘁𝗲𝗺 𝗣𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲: Regular cleaning and maintenance ensure your AC system runs at optimal levels, providing better cooling performance while minimizing energy consumption.
• 𝗜𝗺𝗽𝗿𝗼𝘃𝗲𝗱 𝗔𝗶𝗿𝗳𝗹𝗼𝘄: Clean or replaced filters every 1–2 months ensure proper airflow, reducing strain and lowering energy consumption by 5–15%.
• 𝗘𝗻𝗵𝗮𝗻𝗰𝗲𝗱 𝗛𝗲𝗮𝘁 𝗧𝗿𝗮𝗻𝘀𝗳𝗲𝗿: Clean coils and fins improve heat transfer, allowing your AC to cool more efficiently and reduce bills.
• 𝗢𝗽𝘁𝗶𝗺𝗮𝗹 𝗣𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲: Proper insulation and sealing gaps reduce workload and save electricity.

• 𝗦𝗲𝘁 𝗢𝗽𝘁𝗶𝗺𝗮𝗹 𝗧𝗲𝗺𝗽𝗲𝗿𝗮𝘁𝘂𝗿𝗲: Keep between 22–24°C to save up to 2% of cooling costs per degree.
• 𝗨𝗽𝗴𝗿𝗮𝗱𝗲 𝘁𝗼 𝗘𝗻𝗲𝗿𝗴𝘆-𝗘𝗳𝗳𝗶𝗰𝗶𝗲𝗻𝘁 𝗔𝗖: Choose high ISEER or ENERGY STAR models for maximum savings.
• 𝗔𝗱𝗷𝘂𝘀𝘁 𝗧𝗵𝗲𝗿𝗺𝗼𝘀𝘁𝗮𝘁: Optimize settings for comfort and efficiency.
• 𝗨𝘀𝗲 𝗖𝗲𝗶𝗹𝗶𝗻𝗴 𝗙𝗮𝗻𝘀: Fans improve airflow and reduce energy consumption.

Incorrect Placement of the Indoor and Outdoor Units
One of the most common installation mistakes is placing the AC units in the wrong locations. The indoor unit should not be installed near direct sunlight, heat sources, or in an area with poor airflow. Similarly, the outdoor unit should be installed in a well-ventilated, shaded space with enough clearance for air circulation. Poor placement can lead to inefficient cooling and increase energy consumption, ultimately shortening the life of your AC.

Skipping the Use of a Proper Mount or Support
Improper mounting can cause vibrations, noise, and long-term structural damage. Whether it’s the indoor unit on a weak wall or the outdoor unit without proper leveling, these issues can cause internal components to wear out faster. Always ensure that both units are installed using proper brackets, leveled, and securely mounted to reduce strain on the system.

Not Checking for Proper Drainage and Insulation
Clogged or poorly positioned drain pipes can lead to water leakage and wall damage, while improper insulation of copper pipes can reduce cooling efficiency. Technicians must check that the drainage system is functioning correctly and that all refrigerant lines are properly insulated. These small yet critical steps can go a long way in ensuring your AC’s long life and optimal performance.
