The Thermodynamic Process
The compressor takes low-pressure gas and makes it high-pressure and high-temperature.
Hot gas passes through outdoor coils, releasing heat to the environment and turning into liquid.
High-pressure liquid passes through a tiny valve, causing an instant drop in temperature.
Cold liquid absorbs indoor heat, cooling the room and returning to gas state for the next cycle.
Maintenance & Efficiency
Filter Optimization
Clean or replace filters every 4-6 weeks during peak usage. Clogged filters reduce efficiency by up to 15%.
Annual Servicing
Schedule a professional checkup once a year to verify refrigerant levels and electrical connections.
Drain Line Care
Flush the condensate drain with a water-vinegar mix to prevent algae buildup and water leaks.
Condenser Placement
Keep the outdoor unit shaded and clear of debris (at least 2ft of space) for optimal heat exchange.
The 24°C Rule
Set your thermostat to 24°C (75°F). Every degree lower increases your power bill by roughly 6%.
Seal the Room
Ensure windows and doors are air-tight. Use curtains to block radiant heat from the sun.
