Ducted Heating FAQs

Our goal is to offer you in-depth responses, troubleshooting assistance, and expert knowledge regarding ducted heating systems.

Delve into our FAQs to uncover answers to your questions and ensure optimal performance from your ducted heating systems.

Q: I want a new thermostat because my ducted heating is not working.

A: In about 90% of cases, it’s not the thermostat that’s causing the issue. It’s often the internal board within the ducted heater that’s having some connectivity problems.

To get to the bottom of it and figure out what’s going on, it’s best to have a technician come and take a look.

Q: My gas bill is too high. I want a new ducted heating system.

A: There are several potential reasons for this:

  • Gas prices have significantly risen, impacting bills. To assess this, compare your current gas consumption with the same period last year to see if it has increased.
  • Sometimes, ducts can disconnect, leading to unintended heating under the house or in the ceiling. A family member can help investigate this.
  • Your heater may be running too high, resulting in higher gas consumption.

To address these concerns and find effective solutions, it’s advisable to have a technician inspect your system.

Q: My ducted heating is making funny noises

A: A blocked return air filter may be causing the issue, which can often be resolved by cleaning the filters. Additionally, wear and tear over time can dislodge or wear out parts, leading to unusual sounds.

To identify the exact cause and find the best solution, it’s recommended to have a technician inspect your heating system.

Q: My ducted heating is not working like it used to

A: Several issues may be causing this change:

  • A duct in the ceiling or under the floor may have become displaced, leading to air being dispersed in unintended areas.
  • Obstructions in the airflow path could be causing blockages, impeding the system’s performance.
  • Blocked filters can diminish the system’s efficiency and affect its overall performance.

We recommend scheduling a thorough service to ensure everything is in top condition.

Q: I used to be warm with my ducted heating, but now I am cold.

A: If you’ve noticed a decline in your ducted heating system’s performance and are no longer feeling as warm as you used to, we recommend scheduling a service to get it checked.

Q: Am I smelling gas from my ducted heating system?

A: This could be an issue with the thermostat or the thermistor. Remedies to this problem are not usually expensive.

However, something like this needs to be investigated by a trained technician. Contact us today to arrange a service call.

Q: No air is coming from certain vent/s of my ducted heating.

A: If you’re experiencing a lack of airflow from certain vents, it’s likely a ducting issue. Our technicians are here to help.

They can diagnose the problem and, if possible, rejoin any detached ducts on the spot to restore proper airflow.

Q: The ducted heating thermostat is set to ‘X’ Degrees, but it’s actually ‘Y’ Degrees colder

A: To pinpoint the cause of this issue, it’s advisable to have a technician inspect your system. The problem could be related to the thermostat or the thermistor.

Q: My ducted heating unit is very loud when operating.

A: The loudness could be due to various factors:

  • An unbalanced motor that may require securing or replacement.
  • A collapsed return air duct obstructs the airflow.
  • A faulty combustion fan.

Our technicians can diagnose the issue and recommend the necessary repairs to ensure your heating system operates quietly and efficiently.

Q: My ducted heating turns on, but there’s no air coming out of any vents.

A: It seems like there might be a ducting problem. To get to the bottom of it, it’s best to have a technician come and investigate.

Q: Why do I have to keep pressing the reset button for my ducted heating to function properly?

A: It’s best to have one of our technicians come over and investigate the issue for you, and we’ll make sure your heating is back to working smoothly.

Q: My ducted heating controller screen is blank.

A: First, check if the unit needs new batteries. If replacing the batteries doesn’t solve the problem, the interconnecting cables may be damaged.

Q: My ducted heating controller is showing a spanner symbol. What does it mean?

A: A spanner symbol on your screen often indicates a machine fault or a reminder for service or filter cleaning. Try resetting the system by turning it off and on at the mains.

If the spanner is still visible, it is recommended that you have one of our technicians examine the machine more closely and address any underlying concerns.

Q: I Can Smell Gas or an Electrical Burning Odour from My Ducted Heating

Q: I have a fault (number) on my ducted heating controller. How do I fix that?

A: It depends on the specific fault code and the appliance it’s related to. In some cases, a simple reset can resolve the issue. Try turning the power off and then on at the main power to see if that clears the fault.

If the problem persists or you’re unsure about the code, it’s best to have one of our technicians attend and diagnose the issue.
