Aircon Analysis

There's so much aircon people saying
1. Inverter-based aircon is cheaper in the long run, and
2. Inverter-based aircon is more expensive if you dun use it often,
that we were really stuck in this "left foot first or right foot first" dilemma.

So I took out an excel and did some calculations of our own, with our own estimated variables of projected aircon usage.

If you are considering inverter/non-inverter, you might also want to do something like that. Here's a cut-and-paste of the excel calculations we did, based on Mitsubishi Inverters and non-inverters (we settled on a Toshiba, though):

As we are ASSUMING 8 hours use a day, it makes sense for us to get an inverter as we will have a savings of $541.71 a year for electricity bills, meaning we can recoup the overheads in around 2 years.

Hope this helps. =)

but isn't 8 hrs/day extremely overestimate? unless u on every night la?

Cos we are renting out the 2 common rooms, so we expect 8hrs to be a good estimate...

Of course, if you are using less than 8hr/day, you will have to adjust the figure and recalculate to see if there is a cost justification..

What are the things that you are looking for in an air conditioner? Number one in the list would be reducing energy. It is true that air conditions consume a lot of energy and electricity, thus our electricity bills easily shoot up. This may contribute to financial problems to families. Of course we always want an easy life, and one to contribute to that good mood is to have a cool air when at home, while during the cool weather, we want some warmth.

Never let water sit in the machine for days between uses as a film can form on the top, which can breed bacteria in the enclosed tank. Always empty water and clean the tank when not in use or even when skipping use for one day. You can also refer it to ispring rcc7ak 6 stage on how it can help you upgrade and you can have a less water.
