If more than two people will be in the room regularly, add 600 BTUs per person."
Add 4,000 BTUs if you are putting the A/C in the kitchen. This will give you the ballpark BTUs you should look for. Gaincity Aircon Buying Guide: "Find the square footage of the room you are trying to cool and multiply by 35.
The unit for the blower is BTU or British Thermal Unit (it actually stands for the the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit), and according to Gaincity's website, how you calculate what you need in BTU is as follows: We did not use our contractor's aircon contact, instead preferring to do it on our own, so we engaged the aircon installers separately on our own and arranged for the dates to slot into the rest of the works. For our 3-room flat, we decided to get 3 blowers or a System 3 aircon - one for living area, and two for the bedrooms. Or in my case, productivity might drop by several points as a result of overheating. The all important aircon! Although it is the main splurge in our monthly electrical bill, without the aircon we might shrivel up and die in a sweaty puddle on the floor. The finished product - the aircon in its room!

Replacement of rubbish chute (HIP) only after hacking and retilingĪnother thing is that we asked the HIP office to delay the installation of our new refuse chute till after the hacking and tiling works, otherwise the new chute would be damaged during the hacking process.Īs for the actual hacking itself, I am always surprised to see that the hacking is often done within a day. Note the old rubbish chute in the corner. Since our block is undergoing HIP at the moment, there are always a few dozen of these notices stuck around the lift because everyone is taking advantage of the chaos of the HIP work period to time their noisy or destructive renovations. There are quite a few rules concerning what is hackable and what is not, but if you have looked around the block you will see that a lot of people do quite creative hacking in their HDB flats despite the many constraints.įinally when the notice comes you have to stick it at the lift landing or at the door of the flat to inform neighbours of the works - and the contractor/sub-contractors should also keep to the working hours and days on the permit. If you are hacking any of the walls though, you'll need to submit the plans for approval in advance and this can take longer for the approval of the permit. Our contractor helped us apply for the renovation permit (which takes 2 weeks) and this was straightforward as we were not hacking down any existing walls. To save on costs, we only hacked the kitchen tiles, and instead did an overlay of the tile work in the living area. This would be the only hacking works to be done for our flat. Plumbing (Sinks, Washing Machine, Dishwasher, etc)Īll of the kitchen walls and floor were to be hacked because the existing tile work was in a poor condition and also exceedingly filthy.Household appliances (Fridge, Washing Machine, Dishwasher, etc).Non-built-in Furniture (Ikea, Hipvan, FortyTwo, Qoo10, etc).Lighting Design and fixtures (fans, heaters, oven switch, etc).
