  • Are plants or shrubs able to be planted around an outdoor unit?

    Yes. However, make sure there is plenty of room around the outdoor air conditioning unit so air can freely flow in and out of it. Ensure that the plants are well maintained to ensure that branches and leaves do not get stuck inside the unit.

  • Are there filters that need to be changed in air conditioners?

    Yes, it is best to speak to one of our specialists at dual heating and air conditioning about what needs changing on your unit.

  • Is there any way of conserving energy whilst still operating the unit?

    You can, if you use it economically. If you close windows, doors, curtains and blinds, you can help your air conditioner cool a room more quickly. Air conditioners with inverters settings are economical in power consumption because they automatically adapt and maintain the temperature you require.

  • How often will the filters on my air conditioner need to be changed?

    You should inspect the air filters in your air conditioner twice a month to see if cleaning is necessary. Trapped particles such as dirt can build up and block the airflow. Most residential systems have disposable filters and these should be replaced occasionally. Permanent filters should be cleaned according to the instructions.

  • Do you give free quotations?

    Yes, dual heating gives free on-site quotations for fully installed systems. For ducted heating DIY kits, feel free to send or fax plans for a free design and quotation.

  • What is the average life expectancy for heating and cooling units?

    The average life expectancy of a refrigerative air conditioning system is approximately 10 years. When the air conditioner starts having more problems that are not cost-effective to fix, it may be time to replace it.

  • Can I leave doors and windows open while operating my refrigerative air conditioning unit?

    You can leave windows and doors open. However, it's not recommended if you're trying to heat or cool your home or single room. If you're trying to cool down a room, it's best to close curtains, blinds and windows during the hottest part of the day. This will keep your house cooler and prevent your air conditioner from having to work harder than it has to; ensuring long life.

  • Should outdoor refrigerative cooling units be covered during the winter months?

    Outdoor units are designed to withstand seasonal changes and for this reason they do not need to be covered. The heat pumps inside the unit operate all year round and if you cover them up, it may cause damage to the unit.

  • What is an inverter system?

    An inverter system lets your refrigerative air conditioner alter the speed of its motors in response to cooling demand. The result is a controllable and energy efficient system that is not only cheaper to run, but also uses less power supply.

  • What is the difference between a split system and a multi split system?

    A split system has an indoor and outdoor part that is connected together, whilst a multi split system has just the one outdoor part that is connected throughout the house through multiple indoor parts installed in each room. A split system cools the one room; a multi split system cools the whole house from one outdoor part.
