The winter is about to begin its charms in Australia and to enjoy a warm, comfortable temperature at your house; you will need your heater to blow hot air. Much of the time, when you are troubled by ducted heating blowing cold air, the problem can be minor, and can be fixed in a blink quickly.

Here are some of the most likely reasons for your heater to make your house go all chilly and cold.

1) Wrong Settings On The Thermostat

The settings on the thermostat can fluctuate more easily than you might think. Such as:

  • The temperature on the thermostat is set at a lower temperature than the temperature of your house, making the heater incompatible at beating the cold in its surroundings.
  • The thermostat is set on the cooling mode or fan option.
  • In the case of a new system, you might be clicking the wrong buttons, or the system you bought is not big enough to make your big house warm and cozy.
  • The batteries in your thermostat are dead.  

2) Turned Off Pilot Light

A pilot light which has gone out can cause your heater to blow cold air. The light in old furnaces can easily be extinguished due to a sudden gust of air or low heat supply. Check your heat supply and if that’s fine, ignite the furnace carefully - only if you are sure it's working; otherwise, you can contact a ducted heater service to perform the task.

3) Filters Are Clogged

The filters of an HVAC system can get clogged due to dirt, debris, mould or dust, which interrupts the continuous flow of air to the chambers, causing the system to blow cold air. Replacing or cleaning the clogged filter is a messy task and should be handled by those who know it. On the other hand, if you decide to change the filters, make sure that you are buying the right size filters for your system.

4) Leaking Ducts

Leaking ducts are the hidden culprits of your HVAC system, causing the air to leak through the holes. The ducts can get damaged either by rats and other animals, or by getting old and disintegrating. Repairing the ductworks and filling all the spaces that cause air loss can help you get a good heating quality in your house, for which you will need a ducted heater service provider.

5) Faulty Flame Sensor

Faulty flame sensors refer to dirty or broken flame sensors. If these sensors are not in proper condition, you won’t be able to keep the burner lit for a long time. Fixing it is vital as it can cause a gas leak which is dangerous and risky. Instead of trying to fix or clean it yourself, hiring an expert ducted heater service is recommended.

Ducted Heater Maintenance

To ensure that your heating system keeps working at its full capacity throughout its life, proper ducted heater maintenance is a must. This will help you to fix the minor inconveniences which can cause significant problems in the future.
