Regular maintenance of your air conditioning system is crucial to ensuring efficient operation, lower energy bills and prolonged lifespan. Yet, many property owners overlook scheduling routine check-ups. Here, we explain exactly how often you should maintain your air conditioning unit and why it’s essential.

Recommended Frequency for Air Conditioning Maintenance
At TRS Cooling, we advise scheduling air conditioning maintenance at least once annually, ideally before the warmer months begin. Regular yearly maintenance is key to preventing unexpected breakdowns, optimising performance and identifying minor issues before they escalate.
For commercial settings or heavily-used air conditioning units, we recommend more frequent check-ups—typically every 6 months—to ensure consistent operation and comfort.
Why Regular Air Conditioning Maintenance Matters
1. Improved Energy Efficiency
Regular servicing ensures your air conditioning system operates at peak efficiency. Dirty coils, clogged filters and worn-out components force your air conditioning system to work harder, significantly increasing your energy consumption and utility bills.
2. Enhanced Reliability
Routine maintenance by our trained technicians helps spot potential faults early, reducing the likelihood of unexpected downtime or expensive emergency repairs. Reliable air conditioning is essential, especially during summer months when the system operates extensively.
3. Prolonged Lifespan
A well-maintained air conditioning unit can last significantly longer. Regular inspections, cleaning and timely repairs extend your system’s lifespan, helping you avoid premature replacement and unnecessary expenses.
4. Improved Indoor Air Quality
Dirty air filters and neglected systems reduce air quality, impacting health and comfort. Regular maintenance ensures filters and internal components remain clean, providing fresher, healthier indoor air for your home or workplace.
Key Components Checked During Maintenance
When you schedule your annual or bi-annual maintenance with TRS Cooling, our technicians conduct a thorough inspection, including:
- Cleaning or replacing air filters.
- Checking refrigerant levels and pressure.
- Inspecting and cleaning evaporator and condenser coils.
- Checking electrical connections and controls.
- Assessing airflow and temperature controls.
- Ensuring drainage and condensate pumps operate properly.
Signs Your Air Conditioning Unit Needs Immediate Maintenance
Between regular services, watch for signs indicating your air conditioning system may need immediate professional attention:
- Reduced cooling performance or inconsistent temperatures.
- Unusual noises, such as grinding, rattling, or hissing.
- Higher than normal energy bills without increased usage.
- Visible leaks or excessive moisture around the unit.
- Unpleasant odours when the air conditioning system is running.
If you experience any of these issues, we recommend scheduling a maintenance visit promptly. Early intervention often saves significant costs and inconvenience later.
