Air conditioners are often seen as a summer essential—but in Gauteng, they’re just as valuable in winter. Thanks to inverter technology, many aircons provide reliable heating when you need it most. However, to enjoy consistent warmth and efficiency, you need proper winter aircon maintenance.
If you’re a homeowner or tenant in Joburg, Centurion, or Midrand, this guide to winter aircon maintenance will help you keep your system in top shape throughout the cold season.
❄️ Why Winter Aircon Maintenance Matters in Gauteng
When temperatures drop, your aircon works harder to maintain warmth—especially if you’re using it daily. Without proper upkeep, issues like poor airflow, unpleasant smells, or rising electricity costs can creep in fast.
That’s why consistent winter aircon maintenance is crucial. It helps:
- Improve energy efficiency
- Extend your unit’s lifespan
- Prevent mid-season breakdowns
- Maintain healthy indoor air quality
Skipping these steps now could cost you more down the line.
✅ Tip 1: Clean Your Filters
One of the most important aspects of winter aircon maintenance Gauteng homeowners often overlook is the air filter. A clogged or dirty filter reduces airflow and makes your aircon work harder than it should.
What to do:
- Clean filters every 6–12 months
- Vacuum the filter housing to remove dust buildup
Clean filters ensure smooth operation and help reduce energy bills during winter.
✅ Tip 2: Check for Obstructions Around the Outdoor Unit
Even though most of your attention is on indoor heating, don’t ignore the outdoor condenser. Leaves, dirt, and debris around the unit can restrict airflow and cause overheating.
For effective winter aircon maintenance, take time to:
- Trim back nearby bushes or plants
- Remove leaves, dirt, and obstructions
- Ensure proper drainage to prevent water damage
This simple task helps your system perform efficiently no matter how cold it gets.
✅ Tip 3: Use the Right Aircon Mode for Heating
Your aircon should be in heat mode, also known as reverse cycle, during the winter months. Setting it to the wrong mode could waste energy or deliver cold air instead of warm.
Make this part of your winter aircon maintenance checklist:
- Ensure “heat” mode is selected on your remote
- Set the temperature between 26°C and 30°C for optimal efficiency
- Don’t set it too high—it just increases power usage, not heating speed
Getting this right means warm rooms without spiking electricity bills.
✅ Tip 4: Inspect the Remote and Thermostat
Your remote and internal thermostat control your comfort, so check they’re working properly.
Steps for effective winter aircon maintenance homeowners can do:
- Replace the remote batteries if needed
- Make sure the thermostat is reading correctly
- Avoid placing heat sources near the thermostat (like heaters or kettles)
This ensures your aircon isn’t misreading the room temperature and overworking.
✅ Tip 5: Book a Professional Maintenance Service
DIY care is helpful, but nothing beats a professional inspection. A trained technician can identify issues you might miss and perform deeper cleaning and calibration.
At Sucasa Air, we offer comprehensive winter aircon maintenance packages that include:
- Filter cleaning and sanitising
- Coil and fan inspections
- Gas level checks
- Electrical component testing
- System performance optimisation
We recommend servicing your unit at least once a year—ideally before or during winter if you use it for heating.
✅ Tip 6: Use a Timer to Save Energy
Leaving your aircon on all day isn’t efficient, especially when no one’s home. Use the built-in timer function to schedule operation only when needed.
In your winter aircon maintenance plan, be sure to:
- Set timers to turn the unit on 30 mins before you wake up or get home
- Use the sleep mode at night for gradual temperature adjustment
- Turn off the system when not in use
This helps reduce energy waste while maintaining comfort.
✅ Tip 7: Listen for Unusual Sounds or Smells
If you notice strange sounds, weak airflow, or musty smells, don’t ignore them. These could be signs of blockages, mould, or motor issues.
In Gauteng’s dry winter climate, dust buildup is common—so part of your winter aircon maintenance strategy should include:
- Paying attention to any performance changes
- Calling in a technician if your unit suddenly loses power, leaks, or smells
- Acting early before the issue worsens
💡 Bonus Tip: Keep Doors and Windows Closed
While it may seem obvious, many people forget that cold air sneaks in through open windows or gaps under doors. Your aircon will work harder and less efficiently if the warm air escapes.
As part of your winter aircon maintenance, make sure to:
- Close all windows and doors before turning on your unit
- Use draught stoppers if needed
- Only heat the rooms you’re using
This small habit makes a big difference in comfort and cost.
