Best Aircon Buyers Guide (Philippines)

In a tropical country such as the Philippines, an aircon is a necessity to make us comfortable even with the high heat and humidity. In fact, more Filipinos are buying an aircon now more than ever [1]. And because you’re reading this, you may be buying one for your self as well!

There are a lot of questions to ask yourself when you’re buying a new aircon: What size should I get? What type? Should I get an inverter or a non-inverter?

Since you will be stuck with one model of air conditioner for the next decade or so – and not to mention that they are expensive to buy and to operate – finding the best aircon model for you is crucial.

This is why we here at 101appliance created this comprehensive yet concise aircon buyers guide to help you find the best model for you!

Know your room size

Choosing the right cooling capacity for your aircon will have a big effect on your comfort and your electricity bill. If you choose a model that is too small for your room, it won’t cool it quickly and efficiently; if it’s too powerful, then it can waste energy and make you uncomfortable to boot.

Measuring the size of the room is the most crucial step for aircon buyers, as this will determine how powerful your AC unit should be.

You can have a site survey done by a professional to help you find the right size for your aircon. For most cases, just measuring the floor area of the room using a tape measure will suffice.

Note: An air conditioner’s recommended floor area is measured in square meters (sqm or m2), so use that as the unit of measurement instead of feet.

Know what aircon size to get

In the Philippines, an air conditioner’s cooling capacity is measured in kilojoules/hour (kJ/hr). This is used to measure the amount of heat your aircon can remove from the air per hour of use.

To get a rough calculation, multiply your room size by 500. So if your room is 10 sqm. in size, you need an aircon with 5,000 kJ/hr of cooling capacity – which most 0.5 HP window type aircons have.

Use this chart to get the baseline capacity:

Room SizeCapacity
(kJ/hr)
Estimated
HP Rating
≤ 10 sqm.5,0000.5 HP
10 – 15 sqm.5,000 – 7,5000.75 HP
15 – 19 sqm.7,500 – 9,5001.0 HP
19 – 25 sqm.9,500 – 12,5001.5 HP
25 – 35 sqm.12,500 – 17,5002.0 HP
35 – 43 sqm.17,500 – 21,5002.5 HP

An important note: this table does not consider the room’s heat load (i.e. exposure to the sun, roofing and wall material, and the number of people and appliances in use) – this is what you’ll be missing if you didn’t go through with a professional site survey.

Look at the aircon’s energy guide label (EER)

Air conditioners are notoriously expensive to operate, hence energy efficiency is one of the most important factors that you should take into account when buying a new aircon.

The fastest and easiest way to tell if a model is energy efficient is by looking at how high its energy efficiency ratio (EER) is. The EER is prominently displayed on the aircon’s energy guide label.

The EER tells you how efficiently an aircon uses its power to cool the air. A high EER number means that that particular model is more energy efficient, and therefore has a lower operating cost.

Energy Efficiency Ratio Label

Note: The energy label goes by many names. People refer to it as the EER Label or just the Yellow Label.

Know how to calculate its electricity cost

While knowing the aircon’s EER is helpful, it won’t tell you how much it costs to operate the unit; it will only tell you which model is more efficient in relation to another model of the same category.

To compute the monthly electricity cost for air conditioners, we will use the following computation:

(Power Consumption/1000) x Hours of use x Power Rate =
Daily Electricity Cost

For this example, we will estimate that the electricity rate in your area is ₱9.00/kWh. We will also be assuming that you will use your aircon for 8 hours everyday.

Aircon EER

Since the power consumption figure is in watts (W) but the electricity rate is in kilowatt per hour (kWh), we need to divide the power consumption (930W) by 1,000. In this case, it’s 0.93 kWh. Now, we are ready to compute:

EC (kWh)Power Rate (kWh)Hours
of Use
Per DayPer MonthPer
Year
0.93₱9.008₱66.9₱2,008.8₱24,105.0

Do note that this is only an estimation. Other factors such as where the air conditioner is placed or how you use it will have an effect on your bill.

Will you go for an Inverter or a non-inverter?

If you are concerned about the high electricity cost of your aircon, you should look into inverter aircon models.

Simply put, an inverter is a device that controls the frequency of the incoming electrical current that goes to the aircon’s compressor; this allows the compressor to operate at variable speeds.

After reaching the desired temperature, an inverter aircon does not completely shut off. Instead, it operates at a lower speed to maintain the set temperature.

There are a lot of benefits that inverters give you, but the foremost is that is saves energy and therefore saves you money in the long run. Also they are usually priced around ₱10,000 more compared to non-inverter models of the same capacity.

How much does an inverter aircon save?

To give you a quick comparison, we’ve pitted two 1.0HP window type air conditioners from Sharp (one is an inverter; the other a non-inverter):

Different types of aircon

There are 4 types of air conditioners to choose from – each with their strengths and weaknesses. Choose the one that makes the most sense to your space, budget, and needs.

Window Type Aircon

Window air conditioners are easy to install; there is no need for professional help when setting it up. Most brands include a free wall bracket as well, making installation more convenient.

This is the most common type of aircon in the Philippines. Most houses and condos already have a space in the wall allocated for the unit. You can use an aircon frame/insulation can fill in the gaps if the hole is too large.

This type of aircon is perfect for small rooms, as the smallest capacity available is at 5,000 kJ/hr (0.5HP) – perfect for small rooms below 10 sqm.

Note: The other types of aircon start at 9,500 kJ/hr (1.0HP), which is perfect for rooms that have an area of 15 – 19 sqm.

Pros:

  • Easy installation
  • Good for small rooms
  • Affordable

Cons:

  • Noisy
  • Inefficient in large rooms
  • Limited features

Split Type Aircon

Sharp AH-XS10WF Inverter Split Type Aircon

As the name implies, a split type aircon splits into two units: the indoor component and the outdoor component.

The indoor unit is the one that blows cold air into the room. This is connected to the outdoor unit, which is the workhorse of the aircon.

Since the compressor is located outside of your house, a split type aircon is generally more quiet than a window type.

They are more efficient in cooling as well, as the split type’s wide louver allows a wider coverage of airflow compared to window ACs.

However, they are not a plug-and-play installation, as you need professional installers to set up your split type air conditioner.

Also, the cooling capacity for this type starts at 9,500 kJ/hr (1.0HP), which is not recommended for small rooms below 15 sqm.

Pros:

  • More efficient
  • Less noise
  • Lots of features

Cons

  • Expensive
  • Can’t install yourself
  • Incompatible for small rooms

Portable Type Aircon

If you can’t mount an AC on your wall for whatever reason, you may want to look into portable air conditioner models.

Much like a window type, a portable air conditioner also combines both the indoor and outdoor components into one unit. The difference is that the whole unit is located indoor.

Because the entire unit is inside your home, the heat that is emitted from the compressor and the condenser will be picked up by the AC’s thermostat, making it work harder than it needs too, which makes it less efficient.

However, you should keep in mind that while they are portable, it doesn’t mean that you can just set them up just anywhere.

The hot air from the condenser is transferred outside of the house through an exhaust tube that vents out through a window – and that window needs to have a vertical opening or horizontal opening so that the paraphernalia for the exhaust can be installed.

Also, the water droplets that form because of the condensation will not have a way to escape outside, which is why portable aircons have a water to tank that you’ll have to empty from time to time.

Pros:

  • Portable
  • Easy to install and uninstall

Cons:

  • Takes up floor space
  • Noisy
  • Generally less efficient
  • You have to empty a water tank

Floor Standing Aircon

If you have a large room, a Floor Standing aircon may be your best option instead of purchasing multiple split type units.

A floor standing air conditioner is technically a split type system, as the indoor component is separated from the outdoor component, but the indoor unit is considerably larger and heavier – and yes, it stands on the floor, hence the name.

This type is mostly reserved for businesses or offices, but if your living room (and wallet) is large enough, this can be a viable option.

Do note that the cooling capacity for this type starts at 36,000 kJ/hr (~4.0HP); One floor standing AC unit can be enough to cool a 72 sqm. room. This removes the need to buy multiple split type models. This also saves space outside of your home, as only one outdoor unit is needed.

Also, you have no choice but to hire professional installers for this; not only is the piping and wiring complicated, the unit is so heavy that you can’t do it on your own.

Pros

  • Powerful
  • Heavy-duty
  • Built for large rooms

Cons

  • Expensive upfront
  • Expensive to operate
  • Hard and costly to install
  • Takes up floor space

Where to place your aircon

Generally, you should place the aircon unit at a central location in your room so that the cold air will be efficiently distributed.

Since cold air sinks to the bottom of the room, make sure to place the unit high enough to help cool the room evenly. According to Samsung, the best height for window type units is 3-4 feet off the ground, while a split type should be 7-8 feet up.

If you are setting it up for the bedroom, it is best to place it at the wall behind the headboard so that the cold air won’t be too harsh and uncomfortable.

Also, don’t put your aircon near sources of heat (like other appliances, light bulbs, direct sunlight) as the thermostat can pick up their heat signatures and signal the compressor to work harder.

Other features to consider

  • Ionizers/air purifiers. Some brands offer models with an air-purifying feature that not only deodorizes, but kill viruses and bacteria, keeping your family safe. Look at Sharp’s Plasmacluster Ion Technology.
  • Wifi Ready. If you are on the techy side, some models can be connected to the internet and it will let monitor and adjust the settings of your AC from your phone via an app.
  • Voltage Protection. Some owners connect their units to a separate circuit breaker just for this purpose. Some models have built-in protection against voltage fluctuations, so you better check out which ones do.
