Frequently Asked Questions


  • Q1: What's the best aircon for me? Window Room or

    High Wall Split-Type?

    A1: The most commonly used type of air conditioners for residential homes are window room air conditioners or high wall split type. Some choose window type over split type because it is more convenient versus split type, while others go for split type because of its other advantages.


    Window type air conditioners are ideal for first time air condition buyers since its more affordable and easier to maintain. It is more convenient to install and it does not require any additional fees. Most houses or condominiums also have provisions for this type of air conditioner.


    High Wall Split type is ideal for those who are looking to upgrade their existing air conditioners. Though split type models are more expensive, these types of air conditioners have advantages over window type such as features, flexibility in installation and aesthetics.

  • Q2: What is the right aircon capacity for my room?

    A2: There are many factors that you need to consider when choosing the right aircon capacity for your room (e.g room size, heat load of appliances inside the room, the number of people who will be staying in the room, the room's exposure to sunlight).


    In the absence of any information other than the room size, you may use the table below as guide.


    0.5 HP       FOR ROOMS UP TO 10 SQ.M          1.5 HP        FOR ROOMS UP TO 23 SQ.M

    0.75 HP     FOR ROOMS UP TO 13 SQ.M          2.0 HP        FOR ROOMS UP TO 35 SQ.M

    1.0 HP       FOR ROOMS UP TO 17 SQ.M          2.5 HP        FOR ROOMS UP TO 41 SQ.M


    *Recommended cooling area is indicative only and does not consider room's exposure to sun, ceiling or roof material and heat load inside the room.

  • Q3: Will increasing the temperature make the room colder?

    A3: Increasing the temperature means making the room warmer.  For instance adjusting the thermostat from 20°C to 25°C will make the room 5°C warmer. If you want to cool the room, adjust the thermostat to a lower number.

  • Q4: What makes an inverter air conditioner more energy efficient?

    A4: Have you ever noticed the fixed "on" and "off" sound produced by the compressor of a conventional air conditioner? Every time the compressor turns on, the electricity consumption surges. That's on a constant operation.


    With an inverter aircon, the compressor operates at varying speed. Once the desired room temperature is achieved, the inverter aircon's compressor operates at low speed and stays in that level. This means less electricity surges. Thus, lower electricity consumption.

  • Q5: How often do I need to clean my air conditioning unit's air filter?

    A5: It is important to keep your aircon's filter clean because aside from purifying the air your breathe, a clean filter also helps ensure that your aircon runs efficiently. Thus, it is recommended to clean your air conditioner's air filter every week.

    To clean the filter, just follow these steps:

    1. Remove the filter from the grille.

    2. Tap the filter to remove accumulated dust.

    3. Soak the filter in a clean warm water for 5 -10 minutes.

    4. Shake the filter to remove excess water.

    5. Put back the filter onto the grille.

  • Q6: How often do I need to get my air conditioning unit cleaned?

    A6: It is recommended that general cleaning be done by a CCAC Authorized Service Center at least 3-4 times a year.


    Carrier air conditioning units come with free 1 general cleaning within 1 year from date of purchase. Customers are encouraged to call the customer care to register the unit and book a service.

  • Q7: Why is my air conditioner not cooling properly?

    A7: When the outdoor temperature is too hot or when there are too many people inside the room, the air conditioner will appear not to be cooling properly due to the "higher than normal" heat load. In this case set the thermostat to the coldest setting and the fan setting to high speed.


    Dirty or clogged air filters is the most common cause of poor cooling performance. Check, inspect and wash air filters on a weekly basis whenever possible.


    In addition, it is recommended to have your air conditioner cleaned by our Authorized Service Center (ASC) 3-4 times a year.
