Consumer Council's 8 Tips to Save on Air-conditioner Electricity Bills

Avoid installing the air conditioner in a location exposed to direct sunlight.
Do not block the air inlet and outlet of the air conditioner
In summer, you can draw the curtains to avoid direct sunlight into the room, and try to close the doors and windows to maintain the indoor temperature.
The power consumption of fans is much lower than that of air conditioners. By turning on the air conditioner and the fan at the same time and blowing the cold air closer to the user, the temperature setting of the air conditioner can be increased to save electricity.
If the air conditioner has a timer, you can set the shutdown time to avoid using it for too long or forgetting to shut it off.
When the weather is cooler, use fans instead.
During the summer, it is recommended to clean the dust screen, air inlet and outlet every two weeks.
Using the heating function of the air conditioner in winter is much more energy-saving than using a furnace or fan heater.

Common AC FAQs & Usage Tips

Q1: What should I do if my AC has a weird smell?

Odors are usually caused by mold or dust buildup inside the unit. Check the interior with a flashlight for mold or debris, and clean the dust filter regularly. If the smell persists, some brands recommend setting the AC to 16°C for 1 hour with all windows open to "flush out" the odor. Afterward, remember to turn the temperature back up and close the windows to avoid wasting electricity.

Q2: What should I do if my AC isn't cooling enough?

There are several reasons for this: dusty filters, dirty condenser coils, or low refrigerant. Try cleaning the filters and the interior first, or hire a professional technician to check the refrigerant levels.

Q3: How do I fix a noisy AC?

Noise is often caused by loose parts, compressor vibration, high fan speeds, or dust blockage. You can try installing rubber vibration-dampening pads under the outdoor unit or wrapping the compressor in sound-insulating foam. Lowering the fan speed and regular cleaning also helps. If the problem persists, consult a professional technician.

Use "Fan Mode" to Clear Out Bacteria and Dust

If you haven't used your AC for a while, be sure to set it to "Fan Mode" for at least half a day before regular use. This helps dry out the internal components and removes moisture, preventing you from breathing in bacteria or mold that may have accumulated, which can cause allergies.

Maintenance Tips: Removing Moisture

Especially during humid, rainy, or typhoon seasons, try switching to "Fan Mode" before turning off your AC. This removes moisture from the unit and prevents mold growth. Regular maintenance and cleaning will make your AC last longer and reduce your energy consumption.

Notes on Refilling Refrigerant

If you suddenly notice your AC isn't cooling, you might think it needs more refrigerant. However, it is essential to have a technician check for leaks in the pipes and components first. Simply adding more refrigerant without fixing a leak is a waste of time and money.

Should I turn off the AC when I leave the house? How can I save more?

Method 1: Adjust the temperature.

If you are leaving for only about 2 hours, simply raise the temperature by 1–2 degrees. This is more efficient than turning the unit off and on again, which forces the compressor to restart and consume more power.

Method 2: Choose an Inverter model.

Inverter models are significantly more efficient. Many users report drastic drops in their electricity bills after switching from old, inefficient units to modern inverters.

Method 3: Use with a circulation fan.

For the best cooling and energy efficiency, use a circulation fan alongside your AC. Set the AC to 26–28°C and place the fan under the AC, pointing towards the diagonal corner of the room. This circulates the cool air effectively and saves electricity.

Types of Air Conditioners

Window air conditioners

This type of air conditioner is usually installed on a window frame or a special air conditioner stand with a metal bracket. Some models are even equipped with a remote control and time button.

Split Air-Conditioner

This type of air conditioner is composed of an indoor unit and an outdoor unit. Because the compressor is installed outdoors, it is quieter than the window type when used. Split air conditioners are generally equipped with a remote control and time button.

However, some split-type air conditioners on the market are designed as "window split type", and most of them are called "slim type" or "slim series" split units. Although the appearance of the machine is not much different from the general split machine, it can be installed in most window positions, is smaller in size, and is easier to install.

Inverter air conditioners

This air conditioner has the same window and split designs as the traditional air conditioners (cannot heating), and the more common as split type. The difference between a inverter air conditioner and a general air conditioner is that the snow in a general air conditioner can only flow in one direction to take the indoor heat out of the room; while the snow in a inverter air conditioner can reverse the flow direction.

The air conditioner can provide cooling in the summer, bring outdoor heat into the room in the winter, and blow out warm air at the outlet location.

How to choose an air conditioner? You can consider the points listed below:

Fixed-frequency VS inverter air conditioners

What is fixed-frequency air conditioners?

Fixed frequency air conditioners always maintain a certain output power. When the room reaches a predetermined temperature, it stops running and does not restart until the air conditioner's temperature sensor senses that the temperature in the root room is higher than the set temperature.By adjusting the room temperature by repeating pauses and restarts from time to time, the process causes the room to fluctuate greatly and consumes more power.

However, fixed-frequency air conditioners are cheaper.

What is inverter air conditioners?

Inverter air conditioners automatically adjust the output power according to changes in room temperature. It uses electronics to adjust the operating frequency. Running at a high speed at the beginning of the start-up, the temperature of the room can reach the set cooling level faster.

When the temperature difference in the room is reduced, it is switched to slow operation to maintain a constant temperature to make users feel comfortable. Inverter air conditioners can make room temperature fluctuations less and consume less electricity.

However, inverter air conditioners are more expensive than others.

Air conditioner shopping guide：

1. Power unit comparison table

"Horsepower"(HP) is the unit of power of an air-conditioner. The large number of horsepower of the air-conditioner also means that it consumes a lot of electricity and has a high cooling capacity.

In general, the larger the number of horsepower, the larger the cooling area.

Horsepower	Refrigeration area
1HP	100-200ft
1.5HP	160-280ft
2HP	230-300ft
3HP	330-400ft

Although the larger the number of air-conditioners, the cooler they are when to use, they also bring huge power consumption. Therefore, it is enough to choose the right one.

2. Refrigeration capacity

The cooling capacity of an air-conditioner is very important. The refrigerating capacity of an air-conditioner is generally expressed in terms of cooling capacity. The unit is usually kilowatts (kW) or British thermal units per hour (BTU/h). A high value means a high refrigerating capacity. The choice of appropriaterefrigerating capacity depends on different circumstances, such as the size of the room, the location of the room, the number of residents, etc.

Room size

When buying an air-conditioner, remember to know the size of the room so that the indoor temperature is too low or too high when using it. When you know the volume of the room, you can refer to the cooling capacity of different air conditioners to choose.

3. Placement

In addition to room size, there are other relevant factors that should be paid more attention to. For example, whether the face of the room is constantly exposed to sunlight. In addition, if you live on a higher floor, if you live on a higher floor, it means that the direct sunlight on the room makes the indoor temperature high, and the load on the air conditioner is also greater.

4. Energy efficiency, power saving

The cooling energy efficiency of an air-conditioner is generally expressed in terms of Energy Efficiency Ratio (EER). Energy efficiency ratio refers to the ratio of cooling capacity to electricity consumption, i.e. how much cooling capacity can be converted into each unit of electricity consumption.

A higher value for the energy efficiency ratio indicates that the cooling is more energy efficient and more energy efficient.

In addition, if you want the air-conditioner to be more power-efficient, you can use it with a circulating fan. However, there is knowledge in the position of the circulating fan, and it is more energy-saving to put it in the right position.

5. Noise

The air conditioner will make a certain sound when it is running. If the noise generated during operation is too loud, it will affect the quality of life. Therefore, consumers can do research before making a purchase. Take a look at the opinions of other users of your favourite air-conditioner style, and then compare the different options to choose the best one.

6. Function

Conventional air-conditioners are equipped with a basic filter to keep out particles and dust in the outdoor air. With the development of technology, today's air conditioners even have built-in UV air filtration systems, anti-oxidant filters and other functions.

Installation

InstallationWhen purchasing an air-conditioner, pay attention to whether the price includes the basic installation, and also pay attention to the items included in the basic installation of different brands and retailers. Therefore, you should check the relevant information and details before purchasing. If you are unsure about the installation cost, you can ask the retailer if they can come to your home to see the situation and quote the price, but there may be a fee for this service.

Save electricity

When purchasing for an air-conditioner, remember to pay attention to the energy label on it. There are five levels of energy efficiency, with Level 1 being the highest, i.e. the most energy-efficient and cost-saving, and Level 5 being the lowest. Therefore, consumers should refer to the annual electricity consumption and cooling capacity listed on the energy label when purchasing, compare different models of air-conditioners, and choose the most energy-efficient one.

According to the EMSA report, when purchasing window air-conditioners, choosing energy efficiency level 1 will save 25% of energy compared to level 5. Choosing a split-type air-conditioner can save 61% of energy compared to Level 5 for energy efficiency.

7. Maintenance

With good maintenance services, you can make your air-conditioner last longer. Consumers should check the warranty period and items provided by the manufacturer at the time of purchase. Most new machines have a warranty period ranging from 1 to 3 years. The warranty period of the compressor in the machine is longer than that of the whole machine, generally 5 years. The renewal premium ranges from $510 to $1500.

Usually during the warranty period, you can get free on-site inspections in urban areas, but if you live in remote areas, you will be charged a fee ranging from $130 to $420.

FAQ 1: How do I choose between Inverter and Fixed-speed air conditioners? Which one is more energy-efficient?

When choosing, always check the energy label on the product. Models with a "Grade 1" energy label offer the highest energy efficiency, which saves more electricity in the long run and helps reduce your utility bills.

Additionally, inverter air conditioners consume less power and are significantly more energy-efficient than traditional fixed-speed models.

FAQ 2: How do I decide between "Cooling-only" and "Heat Pump" (Cooling/Heating) models?

You should choose based on your specific climate needs and budget. Cooling-only models are generally more affordable than heat pump models, making them a great choice if you are budget-conscious, don't mind the cold, or already own a space heater. Heat pump models are versatile and can be used year-round—providing cooling in the summer and heating in the winter.

FAQ 3: What should I keep in mind when installing an air conditioner?

In Hong Kong, air conditioner installation is subject to government regulations. Whether you are living in a public housing estate or a private building, there are specific installation guidelines and requirements regarding the placement and mounting of the units.
