1. Cleaning the air filters
It is one of the easiest task and the best way to keep your air conditioner away from the problems. Clean air filters ensure proper air flow inside the system.
If filters are clean air will easily flow through the duct. For keeping your rooms cool in the hot summer days change your air filters every month.
2. Cleaning the condenser coils
The condenser unit of your central AC system is mostly located outside the house. If the condenser is clogged because of the dirt or dust the air flow inside the system will reduce.
Anything which blocks the air flow reduces the cooling capacity of your system. So clean the condenser coils before the start of summer season.
3. Sealing the windows
Keep the curtains of your windows close and seal the windows properly. If there is gap between the windows and the wall cool air will move outside the house and room will not be cooled properly making you feel uncomfortable.
