Ultra Care

Air conditioning is a large family investment, like a car, that must be regularly serviced to ensure operational efficiency and effectiveness through all seasons.

We take pride in installing quality air conditioning products and strongly believe that a regular yearly maintenance should be undertaken.

We highly recommend a yearly service to ensure the following benefits:

  • Maintain economical savings through maintaining energy efficiency
  • Maintain the validity of the manufacturer’s warranty
  • To ensure the unit is operating safely

Prevent further breakdowns and therefore eliminate unnecessary costly call outs.

HANDY TIPS

Always test run your air conditioner a few weeks before the start of summer or winter and make sure it is cooling or heating sufficiently. If the air conditioner needs servicing, it is advised that you do this before the summer or winter season arrives.

    • Always turn on the air conditioner early in the morning as this will reduce external heat entering before the peak of the heat. If you turn on the system in the afternoon or when the air conditioned area may have become extremely warm, it may take sometime to cool the area to the desired temperature
    • Keep outside doors and windows closed at all times
    • Keep doorways to unconditioned areas (eg laundries, bathrooms etc.) closed
    • Note that any doorways on the return air path will need to be kept open, which may mean that doors to an unconditioned hallway will need to be kept open
    • Keep windows, which are exposed to the sun, shaded preferably externally (e.g. shutters), but alternatively by internal blinds or curtains
    • Only operate the required zones and gradually switch zones to other areas if required
    • The recommended set-point temperature for the COOLING mode is 23 degrees Celsius and the fan mode set to CONT.

.

  • We recommend that you operate your system using the timer function, this allows the conditioned area to warm up
  • Keep outside doors and windows closed at all times
  • Keep doors to unconditioned areas (eg laundries, bathrooms etc.) closed. Note that any doorways on the return air path will need to be kept open, which may mean that doors to an unconditioned hallway will need to be kept open
  • We strongly recommend that the fan mode is ONLY set to Auto mode, this allows the fan mode to operate only when the compressor is operating, this will eliminate any cool drafts on the OFF cycle.
  •  On extremely cold days or mornings it may take upto 1-2 hours for the system to warm the area, this is caused by the system requiring to go into the DEFROST mode. It is possible that when the system goes into defrost that a “Swooshing” noise will be heard at the outdoor unit and occasionally steam may be visible.
  • The recommended set-point temperature for the HEAT mode is 21 degrees Celsius and the fan mode set to AUTO.

Switch the air conditioner off at the main power switchboard.  Wait about 1 minute after the air conditioner has turned off before turning the main power switch back on.

You may need to wait up to 5 minutes for the compressor to turn on. If the air conditioner still does not seem to work, it may be faulty. A frequent need for resetting should be investigated. Call our service department and we will assist with your enquire.

On an extremely Hot day the system may trip due to the high demand from the Electricity Grid, this causes the system safety controls to enable the system to operate further and eliminate any possible damage to the system.

Filters require regular cleaning or replacing (depending on the type). As filters accumulate dust they block up, reducing airflow and the cooling or heating capacity of the air conditioner. In addition some types lose filtration efficiency the dirtier they get.

Some filters are located in hinged filter frames attached to the return air grille. These filters are typically residential filters.

They are generally of the washable type and should be cleaned by gently washing with water. If water by itself is not cleaning the filter sufficiently, use a mild detergent. These filters usually require very frequent cleaning. It is recommended to clean the filter monthly.

If you find your filter light continuously flashing, press the on/off button once and it should reset for another 200 hours of running time. Before clearing this, please clean filter as a precaution or simply call us to purchase a HealtheAir Filter which would require changing annually.
