13 Ways To Cut Down Electricity Bill

Receiving a monthly bill expenses is annoying especially if it’s an electric bill. Many of us are not keeping track on  the usage of our electricity . Every time  we receive an electric bill on our door  or through e- mail,  we always  expect the high cost. Based on my personal experience as an electrical engineer, I note down some ways to cut down the electric bill . Some are very common but most of the  time ignored. This list can help you  lessen the electric bill and  save money.

  1. Unplug- Make it a habit  to unplug the appliances/equipment when not in use. When  the battery is full  in charging cellphone, unplug it.
  2. Lower  the aircon temperature-  set the temperature  based on the number of persons in the room. Do not use turbo mode as much as possible.
  3. Clean the aircon– clean the aircon monthly and its filter weekly.
  4. Divide the room- If the area of the room is big, divide it so that the room can cool immediately. You can use curtains as a partition.
  5. Ceiling/ Eelctric Fan/Cooling fan– you can use any of these appliances to help the room cool immediately
  6. Open the windows/vents– very simple thing to do is just to open  the window at daytime so that air can enter the room without using an aircon.
  7. Light Emitting Diode (LED) Lighting– using  LED lamp consumes less power and  affordable in the market.
  8. Lighting– Turn off the lights when not in use.
  9. Old appliances– avoid using old appliances. Mostly old appliances cannot function well however, new appliances are  more energy efficient.
  10. Simultaneous operation. Avoid using  refrigerator, aircon, TV, washing machine, computer and other appliances simultaneously. If you are using the computer, better turn off the aircon, instead use an electric fan. If you are using the washing machine  for such a long time better turn off the TV and  do not do your laundry during peak hours. Better do it at daytime.
  11. Christmas Lights– during Christmas time light up your home until midnight only.
  12. Ironing of clothes– ironing of clothes must be done once a week(at least 3 hours).
  13. Solar – Install Solar power

11 Simple Ways to SAVE Energy on Refrigerator/Freezer

Save Energy and save the Earth. Help fight the global warming.

We all know that the Philippines is one of the highest cost of electricity. In order to reduce our electricity payment here are the simple tips on how to save energy. My family already tried  this and it is very effective. We do hope that you also try and see the difference. It’s just a matter of  habit and discipline. No big cash out is needed.

  1. Refrigerator/Freezer Size – There are a lot of sizes. For small family (1-5 persons) using up to 5cu.ft is enough while for  6 and above persons then select 6cu.ft and above.
  2. Door – make sure the refrigerator door seals are airtight. Test them by closing the door over a piece of paper. If you can pull the paper or bill out easily, the latch may need adjustment or the seal may need replacing.
  3. Monitor Moisture – look for a refrigerator with automatic moisture control. Models with this feature have been engineered to prevent moisture accumulation on the cabinet exterior without the addition of a heater.
  4. Monitor Temperature – don’t keep your refrigerator or freezer too cold. Recommended temperature control 4 & 5.
  5. Regular Defrost – Defrost it at least once a week.
  6. Cover food – cover liquids and wrap foods stored in the refrigerator. Uncovered foods release moisture and make the compressor work harder.
  7. Location – location decides the pattern of its future power consumption. Put in a good circulation of air. Should not be kept close to other electrical appliances. Locate it away from heat sources and direct sunlight.
  8. Cool food- avoid putting hot foods directly in the ref/freezer. Let them cool in the room first.
  9. Keep it full – a full ref/freezer will perform better than a nearly empty freezer.
  10. Label food – Mark items in the freezer for quick identification so that you don’t have to keep the door open longer than necessary.
  11. Installed Solar power – Solar power is non-polluting and free energy heat from the sun.

Window Type vs Split Type Aircon

Window Type:

  • Ideal for small rooms with a window still
  • Relative inexpensive
  • Water vented through the system internally, no tray of water to dispose
  • Slight possibility to interfere with window curtains and drapes
  • Limited areas near the windows
  • Easy to install

Split Type:

  • Ideal for small and medium size room
  • More expensive
  • Can hook multiple air handlers with one condenser while cooling different areas
  • Minimal noise
  • Energy efficient
  • Can be wall mounted, floor mounted or ceiling suspended
  • Any room with or without a window
  • Water is collected in a tank or tray and has to be emptied regularly
  • Require professional installation


Small Room—for room smaller than 25sq.m (1.0HP or below unit aircon)

Medium Room—for rooms between 25 and 44sq.m (1.5HP or 2.0HP aircon)

Large Room—for rooms between 50 and 72sq.m (2.5HP to 3.0HP aircon)
