Your aircon's efficiency heavily depends on the space it will cool. Getting a bigger or smaller aircon is not necessarily better. An aircon unit that's too big for the size of you room is likely to turn on and off more frequently and in effect consume more energy in the process. 
On the other hand, an aircon that's too small for the size of your room never stops running as it will continuously work to reach your desired temperature level. However, it won't have the enough power to do this. 

As a consequence, an aircon that's not right size for your room can significantly increase your electricity consumption per month.

​Below is a guide to finding the right aircon size for your room.

With the high cost of electricity today, it pays to know how much power do common household appliances consumes and how it affects our monthly electricity bill.

We can significantly lower our consumption if we become aware of how energy is used, where it's wasted, and how it can be used more effectively and efficiently in everyday life.

The following are the computation of the electricity consumed by most home appliances based on the Meralco Appliance Calculator (MAC). ​

​​A 10kg automatic washing machine used twice a week for 6 hours cost P528.89 in electricity bill a month.

​A regular 16 inch desk fan used for 20 hours a day, 7 days a week will have an electricity cost of  P476.94 a month.

​A regular 1.0 H.P airconditioner used for 8 hours a day, 7 days a week will have an electricity cost of P1,890.97 a month, while the inverter type equivalent will have an electricity cost of P1,009.75

​A vacuum cleaner used for 1 hour a day, 7 days a week will have an electricity cost of ​P238.47 a month.

​A 3.0L rice cooker used for a total of 1 hour a day, 7 days a week will have an electricity cost of P298.09 a month.

​A microwave oven used for a total 45 minutes a day, 7 days a week will have an electricity cost of P268.28 a month.

​A 32" to 42" LED TV used for 12 hours a day, 7 days a week will have an electricity cost of  around P429.25 a month.

A desktop computer set used for 8 hours a day, 7 days a week will have an electricity cost of P536.56 a month.
​

A 20 Watts Flourescent lamp used for 10 hours a day, 7 days a week will have an electricity cost of P95.40 a month.
​

A 10 watts CFL lamp used for 10 hours a day, 7 days a week will have an electricity cost of P P29.81 a month.
​

​A 5 watts LED lamp used for 10 hours a day, 7 days a week will have an electricity cost of P P14.90 a month.
​

A flat iron used for 1 hour a day 5 days a week will have an electricity cost of  P212.92 a month.

​A common mistake in kitchen cabinet design is installing the upper cabinets too high. This often necessitates the use of a step stool just to be able to reach upper shelves.

So how high should upper kitchen cabinets be installed? Answer: It should be within 15 to 18 inches from the countertop. With this height, average user will be able to reach all shelves without a using a step stool.

Some exceptions to these standards are the upper cabinets that is above a refrigerator and the cabinet above a cooktop,

​​A range hood is actually one of the most important appliances in the kitchen. It consists of a canopy and a blower to extract the air pollution caused by cooking. By capturing and eliminating the contaminated air right at the source, the range hood maintains the air quality in the kitchen and makes cleaning much easier.

​In​stalling the rangehood too far form the cooktop makes it ineffective while positioning it too close makes it a fire hazard so careful planning must be followed.

In general, most installations require a distance of 24 inches between the bottom of the hood and the cooking surface. 

Over a gas range, this distance should be between 24" and 30", unless otherwise specified.

This is a general guideline. It is always best to refer to the installation manual for your specific rangehood model.
