With the summer fast approaching, a properly air condtioned, chilled, calm home is something everyone looks forward to at the end of the day, and most of us get stumped when this appliance, comes to a grinding halt due to a glitch. It usually takes hours to get a technician to come, check your appliance on a busy day, and might take days altogether after that, to get it repaired in case of a serious fault. So here are some tips to avoid this fateful condition, and to make sure your beloved air conditioner runs efficiently for a long time. 1) Insulation. Make sure your whole air conditioning system is properly insulated and leak proof. Check your walls for any air leaks that might affect the proper working of the air conditioner. Make sure all your windows are leak proof, and replace the heavily rusted parts of your window sills, if necessary. Also make sure you replace all the rusted and cracked parts of metal in your air conditioner units. This also includes the duct lining and the other parts of the air conditioner that might be present outside the building. 2) Maintenance and Servicing. Have your air conditioner serviced by a professional atleast once every six months. A professional can check the direction of air flow, inspect the coils and assess its efficiency. And make sure you have a proper, clean surrounding for the appliance. Dusty surroundings can not only reduce the efficiency of the air conditioning unit, but also cause problems like asthama, wheezing and other air-borne, particle-spread diseases. 3) Placement. Make sure the air conditioner unit’s registers are not covered. This includes window curtains and hanging plants too. Ideally, the curtains should be held about 25cms above your unit, in case of a window type air conditioner. Incase of a seperate heat rejecting unit, like in the case of a portable type and split type, make sure the heat rejecting unit is not kept in direct exposure of sunlight. Use curtains to block the heat and sunlight into the room during the hottest part of the day. This not only prevents unnecessary heat accumulation in your room, but also keeps your cooling appliances clean. 4) Chemical Cleaning. Use chemical cleaning to clean the insides of your coils. Removing the dust accumulation on the coils helps air flow, and reduces problems in the long term. Most importantly, avoid vaccuming the coils, because this causes serious health problems.
