Installation FAQ

1What air-conditioning system should I buy for my home in Singapore?

Singapore is a tropical city-state with specific housing dimensions. You should consider these factors before buying an AC unit.

a.) Know the area of your home that you want an air-conditioner installed
b.) Determine the cooling capacity required for each space
c.) Find the best brand and AC unit type you want. Consider AC services as important.
d.) Work with your budget

2How to calculate the air-conditioning power needed to cool your home?

In general, the equation below is used to determine the power capacity of the AC unit needed to cool a particular space:
Area (length x breath) x 65 = BTU/hr
E.g. Room (8 ft x 8 ft) x 65 = 4,160BTU/hr
KWh = BTU/hr x 0.000293
Using this equation, an hour of air-conditioner operation will consume 4160 BTU/hr of energy.
In KWh, the energy use is at 1.22 KWh (4160 BTU/hr x 0.000293).

3What brand should I buy?

Most air-conditioner brands selling their machines in the country actually have models that perform very well. We, at Billy Aircon, do not champion any brand to our clients. Clients should also consider how their machine is installed in their home. The installation services we provide at Billy Aircon will make sure your machines are installed properly. This is coupled with our quality maintenance work to ensure your machine will work efficiently and last for a long time.

4How does an inverter air-conditioner differ from other types of AC’s?

An inverter aircon features the inverter circuit technology which allows the machine to regulate and balance its compressor on its own. This allows it to operate efficiently and consume a lot less electricity than other AC types.

5What are the main differences in a split air-conditioner and window-type air-conditioner?

Window-type AC’s are usually installed through a hole or opening at the wall of a house. The aircon casing houses the compressor, coolant, and other parts for it to operate. You don’t need to connect pipes during the installation.

Split-type AC’s have a separate machine for the compressor and fan. The FCU (Fan Coil Unit) is the one you see inside the room which delivers the cold air. The cool air comes from the outside compressor which gathers surrounding air and cools it. Air travels through the pipe connection system of the AC unit. It can also have multiple FCU’s so that the compressor delivers cool air to more than 1 room or space.

Here are other differences of a split-type and a window-type AC:
a.) Electricity consumption is higher in Window-type AC’s than split-type AC’s. You spend more KWh which results in a higher electric bill on average.
b.) The window-type is also noisier since the compressor and fan are in one case and it’s installed on the wall.

6How long will the installation process last?

Depending on the type of AC to install and how large the work load is, a typical installation will take about 4-6 hours.

7How long is the warranty coverage for my AC?

Most AC units sold by Billy Aircon comes with a 5-year warranty for the compressor and a 1-year warranty for the entire unit.

8How long will a typical home air-conditioning unit last?

Professionally installed and serviced air-conditioning units will last an estimated 6-7 years. Our professional service at Billy Aircon assures our clients that their air-conditioning unit will last for as long as it should.

Servicing FAQ

1What keeps my air-conditioning unit from cooling efficiently?

Here are some examples of AC problems that affect its ability to cool efficiently:

Clients should call Billy Aircon servicing at least once a year to avoid any of these problems from popping up.

2What causes the water leaks on my AC?

A couple of reasons why:

a.) General wear and tear on certain parts
b.) Badly installed air-conditioning unit

The drain and fan coil pipe connection may be blocked by dirt which causes the condensed water overflow. Its pipe gradient may also be too thin which causes the condensation to happen outside the pipe allowing water to escape.

3Why is excess water dripping from the outside part of my window-type?

The AC condenser cools the surrounding air which causes the condensation of water on your unit.

4Why shouldn’t I put a catch basin for the dripping water from my AC?

The tray collects stagnant water which will likely become a breeding ground for disease-carrying mosquitoes.

5Where does the foul smell from my air-conditioner come from?

The AC unit cools the surrounding air and if the surrounding air comes with a foul smell the cooled air will come with the same smell. If you feel like the foul smell comes from inside the unit, you should call for an AC servicing team to have it checked out.

Billy Aircon delivers high quality air-conditioning service in and around Singapore.

6How come my AC unit produces a lot of noise?

Your AC’s evaporator coil must be filled with a lot of dirt. Calling in some maintenance work can fix this minor issue.

7Why does the fan still run even though I didn’t turn on the condenser on my AC?

The fan coil is separate from the compressor and condenser which means they run independently. A broken condenser will not be able to cool the surrounding air and it will only pass warm air to the fan that delivers it to the room.

8What will happen if I don’t call aircon servicing on time?

Wear and tear may catch up and your unit might break down sooner than it should. We, at Billy Aircon, recommend that you call aircon servicing once a year.

9How many times should I call for maintenance service in a year?

A maintenance service call will be enough to prevent issues on your AC unit.

10Does a DIY aircon service method work for home users?

You need technical training to perform aircon servicing. It will save you a lot of money if you hire a professional aircon service provider to do maintenance and repair work because you avoid the possibility of doing it wrong and you keep future problems from happening as well. The Billy Aircon service team is one of the best technical service team in Singapore.

11Is it possible for me to do my own chemical wash?

We tell our clients not to dismantle their unit on their own because it can possibly cause more problems.
