What’s the Aircon Outlet Computation in the Philippines?

In the Philippines, electricity consumption is measured in kilowatt-hours (kWh). You can follow a basic formula to compute the air conditioner’s daily consumption. First, your air conditioning unit’s horsepower (HP) must be converted to watts. This conversion is done by multiplying the HP by 745.7 (1 HP = 745.7 Watts).

Once you have the wattage of your unit, you multiply it by the hours you use the air conditioner per day. This will give you the total watt-hours consumed. To calculate the cost, multiply this value by your provider’s electricity rate.

It’s important to note that the electricity rate may vary depending on the time of day (peak and off-peak rates) and your specific rate plan with your provider. It’s advisable to check your electricity bill or contact your provider to obtain an accurate rate.

You must also include the Value Added Tax (VAT) in the calculation. The VAT rate in the Philippines is currently set at 12%. By adding the VAT to the total cost, you can more accurately represent the actual expenses incurred.

Suppose you have an inverter aircon, which automatically adjusts the compressor speed to meet the cooling demands. In that case, it is crucial to consider the average reduction in energy consumption offered by the appliance. 

Inverter air conditioners are known for their energy-saving benefits compared to non-inverter models. This reduction in consumption can vary depending on the specific inverter technology used in the unit.

Considering these factors and applying the formula correctly, you can estimate the daily electricity consumption and associated costs of running your air conditioner in the Philippines. It’s important to remember that this calculation provides an estimate and that actual consumption may vary depending on various factors, including usage patterns, room conditions, and the air conditioning unit’s efficiency.

What are the Reasons Why My AC Causes High Electric Bills?


If you reside in the Philippines, you’re likely accustomed to the high electricity bills that come with running your air conditioner. However, if you’ve noticed a higher-than-usual cost this year, you may wonder why your air conditioner is so expensive.

While air conditioners consume significant electricity, reduced efficiency can contribute to higher electric bills. Several factors related to the air conditioner can lead to increased costs, including dirty filters, duct leaks, failing parts (such as motors and capacitors), low refrigerant levels, lack of maintenance, an old system, and poor installation.

Dirty Air Filters

Air filters are essential in keeping your air handler, ducting, and indoor coil clean. When filters are not replaced regularly, they become clogged with debris, restricting airflow throughout the ductwork. 

Restricted airflow causes the unit to take longer to cool the room, resulting in increased running time and overheating of motors and compressors. To maintain your unit’s efficiency and prevent high electric bills, it is essential to either clean reusable filters or replace disposable ones every 30 days.

Duct Leaks

Ductwork plays a significant role in distributing air throughout your home and affects the efficiency of your air conditioning system. Duct leaks reduce the system’s ability to circulate air and satisfy the thermostat’s desired temperature. 

When the air conditioner takes longer to reach the desired temperature, it runs harder and longer, leading to higher electricity bills. To address this issue, it is recommended to have a duct seal performed by professionals to improve airflow and system efficiency.

Failing Parts (Motors, Capacitors, etc.)

Failing parts such as motors, capacitors, and compressors can negatively impact your air conditioning system’s efficiency, increasing electricity consumption. For instance, a failing condenser motor struggles to remove heat from your home effectively. 

The motor’s prolonged operation and the thermostat’s inability to be satisfied lead to increased running time and higher electric bills. It is essential to address failing parts promptly to prevent system breakdowns and maintain efficiency.

Low Refrigerant

Air conditioners and heat pumps use refrigerant to facilitate the process of transferring and removing heat from the interior of a home or building. This refrigerant cycle is essential for effectively operating air conditioning and heat pump systems in maintaining desired indoor temperatures. 

Low refrigerant levels hinder the system’s ability to remove heat efficiently, forcing it to work harder to satisfy the thermostat. The increased workload leads to higher electricity consumption. Low refrigerant is often caused by leaks in the system’s coils and line sets. Professional service is necessary to diagnose and repair these leaks accurately.

Lack of Maintenance

Regular maintenance by HVAC experts is essential to ensure system efficiency and prevent potential breakdowns. Professional HVAC technicians have the necessary tools and expertise to assess your air conditioning system’s condition and performance. 

Recommendations for maintenance may include coil cleaning, capacitor or motor replacements, surge protectors, hard start kits, duct sealing, and programmable thermostat installation. Regular maintenance significantly reduces the risk of high electric bills.

Old System

Older air conditioning systems are less efficient, particularly if they have not received regular maintenance. Older units with low SEER ratings and years of exposure to the hot climate can increase operating costs. Some units may even rust out due to a lack of maintenance and old age.

Bad Installation

A poorly installed unit can also contribute to high energy bills. For example, an oversized unit will short cycle, turning on and off rapidly. This frequent cycling increases energy consumption since air conditioners use the most energy during start-up. Other issues stemming from improper installation include:

  • Missing parts
  • Faulty electrical connections
  • Inadequate brazing and welding
  • Non-sealed duct connections

In addition to increased electric bills, a bad installation can lead to frustrating breakdowns.
