Ducted Heating System Maintenance – What Will My Technician Check For?

Ducted heating components may require regular services and repairs. They are under continuous heat and pressure and can lose efficiency over time. It's also vital to replace parts that have worn out with the same type of part, not a cheaper equivalent. Most ducted heating repair companies recommend getting your system repaired or serviced once a year, or at least every two years, depending on the brand and age of your unit. Here's what to expect from a standard company approved service:

  • Regulator/Flow switch check

The flow switch is designed to maintain the right amount of airflow to different areas in your home, which keeps you comfortable but ensures energy isn't wasted having too much air forced through your system when not required. Your company technician will check your flow switch is working efficiently and make any adjustments to improve its performance.

  • Heater exchanger inspection

The heat exchanger is the part of your unit where hot gases are exchanged with cold air from outside via a finned surface made of metal. Unfortunately, the fins may become damaged over time due to corrosion, which means your heating won't be as efficient as it could be. When you book in for a service, your technician will inspect the condition of this component, replacing it if necessary.

  • Ductwork check

Although much harder to reach than other parts in your ducted heating system, problems in the ductwork can have a significant impact. Your technician will check the ductwork for signs of damage, and if necessary, perform a minor repair or replace components as required.

  • Leakage check

Over time, your heating system can develop leaks, which may reduce energy efficiency and even make it less comfortable. By checking for leakage during an annual service, you can prevent future issues that are much more difficult and costly to resolve. To identify any problems with your sealing, we offer a smoke test as part of our routine annual servicing instead of charging as a separate call-out fee as some other companies do. This is because the cost of the smoke testing is minimal compared to what you'd pay if we had to come out now and find the fault quickly.

  • Air filter inspection

The air filter is designed to remove dust and other small particles from your ducted heating system, so it's essential to keep this clean, or you won't be getting efficient heating. When a service is booked in, a qualified technician will inspect the filter's condition and replace it as necessary. It's generally recommended to replace them every three months for optimal performance.

  • Safety controls check

It's also a good idea to have safety controls checked - these can include boilers with pilot lights, multi relays and thermostats for heat pump units. If faulty, you risk not having the operation of your heating either now or in the future if left until next years’ service or until it happens.

If you have an older system, you may need to replace old parts. This is because technology has come a long way, and components made 10 years ago maybe more inefficient than ones available now, even if they are the same size.
