If your reverse cycle air conditioner is blowing air but not warming your home, you’re not alone. Across Western Sydney and the Northern Beaches, homeowners frequently report this frustrating issue—especially in the cooler months.
Here are common reasons your aircon may not be heating as it should:
1. Incorrect Mode or Settings
Your system may be set to cooling, fan-only, or auto mode. Be sure to double-check the remote for “HEAT” mode and adjust the temperature above the current room reading.
2. Dirty Filters or Internal Build-Up
Blocked air filters or internal dirt build-up can limit airflow and reduce performance. This is one of the top causes of heating inefficiency we see during aircon repair call-outs in Sydney.
3. Refrigerant Issues or Gas Leaks
If your system’s refrigerant levels are low, it can’t effectively absorb and expel heat. This usually requires professional HVAC diagnosis and repair.
4. Sensor or PCB Failure
A faulty sensor or PCB board may fail to trigger the correct heating cycle. We often diagnose this during our aircon inspection services.
