Plum Heating and Cooling’s Frequently Asked Questions

Evaporative Cooling
Does evaporative cooling work on humid days?

Evaporative cooling does work on humid days, although it is definitely not as effective on humid days compared to dry days. This is because evaporative cooling adds more moisture into the air. To get the best from your system on these days, try opening more of your doors and windows and put the fan speed on 100%. Please make sure it is on ‘Fan Only’, instead of ‘Cool’.


How many windows/ doors do I have to open to use my evaporative cooling effectively?

On average, two full doors/windows should be opened when using the evaporative cooling system. You can experiment yourself to find the perfect balance.


How do I use my Coolbreeze evaporative cooler controller?

The evaporative cooling system controller is very easy to use. All you need to do is press the ‘Cool’ button and walk away. The system will go through its ‘pre-wash’ cycle where it cleans the filter pads before use. This takes around 7-9 minutes to complete, then the evaporative cooling system will turn on and start cooling the home.


My evaporative cooling system has been recently installed and I have noticed a smell. Is this normal?

Yes, this is completely normal. The smell is the glue in the new filter pads coming into contact with fresh water for the first time. The smell will be present for the first few times you use the evaporative cooling system but it will disappear. A good way to get rid of this smell quickly is to turn the evaporative cooling unit on using the cool mode, then turn it off when the evaporatoive cooler starts blowing cool air. Repeat this cycle 4-5 times throughout the day and the smell should almost be gone!


How long do evaporative cooling system filter pads last?

Filter pads can last from 7-10 years. When you have your evaporative cooling system service Melbourne done by Plum, the technician can let you know the state of the pads in the unit. The Coolbreeze evaporative cooling system units come with a self-cleaning cycle wash cycle which prolongs the life of the filter pads as they are always clean before use.


There is a lot of moisture on my floors, what’s going on!?

If there is moisture on your floors, it means you do not have enough doors and windows open for the air to escape. This can happen if it is extremely humid weather. Open up more doors or windows or lower the fan speed of the evaporative cooling system unit.


There is no power to my evaporative cooling system controller, is it broken?

If there is no power to your evaporative cooling system controller, it could be a few things:

  1. Circuit breaker has been tripped, check your meter box and ensure all circuit breakers are on.
  2. Powerpoint in the roof (near the cooler location) has been turned off.

If you have checked both of the above and there is still no power to the controller, please call our office as it sounds like it could be a faulty mainboard or controller! We can do evaporative cooling repairs in Melbourne.


How often should I have my evaporative cooler serviced?

We recommend an evaporative cooling system service Melbourne every 12-24 months. It is usually a good idea to do it just before the hot summer weather hits to ensure it is working at its best. (August-September-October).


Can I zone my evaporative cooling system?

You could zone your evaporative cooling system, although we strongly recommend against doing so. You will never get your return on investment by purchasing a zone motor for the system, as it will cost the same to run the evaporative cooler with our without zones. You might as well cool your whole home!


How much cooler should it be in my home than outside?

An evaporative cooling system usually gets the indoor temperature between 6-13 degrees below the temperature outside (when it is hot of course), depending on the humidity level.


Wall Hung Split System
I noticed there is a flashing green light on my Hitachi Split System air conditioner, what does this mean?

It’s nothing to be worried about! The flashing green light on your split system air conditioner is a reminder to clean your filters and appears after a certain amount of operating hours. To reset the reminder, simply hold the blue ‘Swing’ button for a few seconds when the control is turned off and it will disappear.


What does it mean if my split system air conditioning unit is dripping water?

If your split system air conditioner is dripping water from the inside unit, please give our office a call as the drain at the back of the cooling system may be blocked or dislodged. We can complete split system repairs in Melbourne.


My split system air conditioning unit is not blowing cool air.

If you have checked your settings on your cooling system controller and your split system air conditioner is still not blowing cool air, please contact the Plum office for split system repairs Melbourne, as it may need a service call out.


How often should I have my split system air conditioner serviced?

We recommend that a split system air conditioner is serviced every 12-24 months. It doesn’t really matter which time of the year, as a split system air conditioner has both heating and cooling in the one unit so it will always be used.


Why is there water coming from my outdoor air conditioning unit?

All refrigerated outdoor air conditioning units will condensate water, especially when they are on the heating cycle where it may condensate a few litres of water when being used. This is perfectly normal, no cause for concern, and no need for an air conditioning repair Melbourne.


Ducted Refrigerated Cooling
What is zoning in a ducted heating and cooling system?

A ‘Zone’ is able to shut off the heating or cooling in certain areas of your house. This is especially handy when you want to turn off areas that are not being used (such as living areas at night, some bedroom areas during the day, etc) to lower the running cost of the ducted heating and cooling system.
