5 Easy Tips to Fix Common Ducted Heater Problems in Canberra
Ensuring your ducted gas heater is working efficiently is vital during Canberra’s cold winter months. Fortunately, many common heating issues are easy to diagnose and resolve without needing professional assistance. Below are five simple troubleshooting tips to help restore your heater’s performance.
But if your issue goes deeper, rest assured – Stag Electrical’s air conditioning and heating specialists are ready to help.
1. Check Power Supply & Pilot Light
If your heater won't turn on:
- Confirm the unit is connected and the circuit breaker isn’t tripped.
- If it’s gas-powered, ensure the gas supply is active.
- Check that the pilot light is lit and stable.
If all seems normal but the heater still won’t start, it’s time to call in a qualified technician.
2. Inspect & Clean Air Filters
Clogged filters obstruct airflow and reduce efficiency, potentially leading to long-term damage. To maintain airflow:
- Inspect filters every 3–6 months.
- Clean or replace filters based on condition.
- Ensure vents and returns are dust-free.
Simply keeping filters clean can restore heating power and prolong system life.
3. Check Thermostat Settings
A thermostat issue is often the culprit behind poor heating performance. Here’s what to check:
- Ensure it’s set to Heat mode.
- Raise the temperature setting above current room temperature.
- Replace old batteries or recalibrate the unit if it’s not responding correctly.
If problems persist, Stag’s team can evaluate your thermostat’s accuracy and functionality.
4. Clear Ductwork Obstructions
Blocked or disconnected ducts can cause poor or uneven heating. Try this:
- Examine accessible vents and ducts for visible blockages.
- Ensure no furniture, rugs, or curtains are covering vents.
- Suspect a blockage deeper in the system? Let a professional handle it safely.
Duct obstructions can significantly reduce heating efficiency—early detection saves repair costs.
5. Schedule Regular Maintenance
Preventative maintenance is key to long-term performance. An annual service typically includes:
- Full system inspection and testing
- Fan and motor cleaning, lubrication, and calibration
- Checking gas pressure and system integrity
