• Seal air leaks:
Prevent air leakage by sealing gaps around windows and doors.
• Adequate insulation:
Ensure proper insulation to minimize heat gain and loss.
• Strategic landscaping:
Plant trees or shrubs to shade your home from direct sunlight.
• Ventilation:
Improve ventilation to remove excess heat and humidity, reducing reliance on AC.
• Energy-efficient windows:
Install double glazing to keep heat out during hot spells.

• Loud noises:
Unusual sounds like clanking, grinding, or rattling from the outdoor unit indicate potential problems with the compressor.
• Warm air from vents:
If the air from the vents isn't cool, it could mean the compressor isn't functioning properly.
• Reduced cooling capacity:
Your AC unit may be running constantly, but the house doesn't cool down as it should.
• Refrigerant leaks:
Leaks can occur at the compressor and lead to reduced cooling efficiency.
• Tripping circuit breaker:
A failing compressor can draw excess current, causing the breaker to trip repeatedly.

• Spray the coils with a garden hose, avoiding the electrical components.

**Indoor unit:**

• Turn off power.
• Replace or clean the air filter.
