This post continues from our previous,How to make your air cond last longer (Part 1)
Air cond not cooling as well as it used to? Maybe it’s time to get dirty and check the air filter.
Dust is your enemy
When the air cond evaporator is in action it takes in the heat from its surroundings. Dust particles are present in this hot air. The air filter prevents the dust from getting to the evaporator coil. If dust accumulates on the evaporator coil it will not work efficiently in absorbing the heat from your room, that is, it won’t cool your room as quickly as it would normally.
If you live in a dusty environment, you’ll need to clean the air filter regularly. Do this by removing the front grill of your indoor unit to expose the air filter. Then gently pull off the filters and wash it under running tap water. If the dust is stubbornly sticky brush the filter gently with a sponge or brush. Dry the filter thoroughly under the sun before putting it back into the air conditioner. Needless to say, you shouldn’t be running the air cond when the filter is removed. More importantly you should read the operating manual before beginning the cleaning processs.
Have your air conditioner serviced frequently
There are two types of services that can be carried out, ‘normal’ or ‘chemical’. In a normal service, the air filter, grills, and exterior parts are cleaned and the other operating parameters such as the gas pressure, running ampere and temperature are checked. In a chemical service, the air conditioner is dismantled for the condenser and evaporator coils to be cleaned with alkaline-based solutions. We recommend that you carry out normal maintenance monthly or every two months. If the air conditioner is not in regular use then maintenance can be less frequent. A chemical maintenance is required if the normal service does not improve the efficiency of the air cond. Again, depending on usage levels, chemical maintenance for an air cond may be carried out from two to five times over a 10-year period.
Buy the right size or unit for your room
Installing an undersized unit is a principle mistake home owners make. A unit with insufficient BTU will have to work doubly hard to achieve the desired temperature. You’ll also find you have to run the aircond for longer periods. This puts stress on the compressor and will surely shorten the life span of the unit. Our previous post on top questions to ask when shopping for an air conditioner offers tips on how to pick the right size for your room.
Switch it off
Yes, Malaysians love their air conditioned homes but really, there’s no need to keep it humming the whole night. Use timers to set the AC to switch off after a couple of hours. Keep the space enclosed and use good old fashion fans to circulate the cool air. An average temperature of 24C – 26C is comfortable enough for most people.
There we hope you enjoyed reading these tips. A little attention will go a long way to making your air cond last and saving you some money.
