Temperature Best Practices
Optimal Temperature Settings
- Daytime (Occupied): 24-25°C for comfort and moderate cost
- Sleep Time: 26-27°C (body needs less cooling during sleep)
- Away from home: 28°C or turn off
Gradual Cooling
Don't set AC to minimum temperature abruptly. Gradually reduce over 10-15 minutes for comfort and efficiency.
Maintenance Best Practices
Monthly Tasks
- Clean indoor unit vents and grilles
- Check outdoor unit for debris
- Listen for unusual noises
Quarterly Tasks
- Clean/replace filters
- Check drain line for blockages
- Inspect outdoor unit condition
Annual Tasks
- Professional servicing (before summer)
- Deep cleaning of coils
- Refrigerant level check
- Electrical connection inspection
Usage Best Practices
Smart Scheduling
- Pre-cool home 30 minutes before peak heat
- Use timer to turn off during peak tariff hours
- Run AC at night if possible (cooler outdoor air, lower tariffs)
Zoning
- Use AC only in occupied rooms
- Close vents in unused rooms
- For split ACs, choose models with multi-zone capability
Combined with Fans
- Use ceiling fans at high speed with AC at 26°C
- Fans improve air circulation and perceived coolness
- Turn off fans when AC is off (fans add heat)
Installation Best Practices
Placement
- Indoor unit: 7-8 feet above ground, 3 feet from corner
- Outdoor unit: Shaded, 2 feet clearance on all sides, slightly elevated
- Away from heat sources (kitchen, boiler)
Piping
- Copper pipes properly insulated to prevent condensation
- Shortest pipe run possible (reduces pressure drop)
- Properly supported pipes without tension
Seasonal Best Practices
Before Summer (April-May)
- Professional pre-season service
- Filter replacement
- System testing for 30 minutes
- Cleaning outdoor unit area
During Summer (June-August)
- Filter cleaning every 2 weeks
- Weekly check for water leaks
- Monitor electricity consumption
- Ensure drainage is clear
Post-Summer (September-October)
- Run fan mode for 3-4 hours to dry internal parts
- Filter cleaning before storage
- Covering outdoor unit (optional)
- Note any issues for next service
Energy Conservation Best Practices
- Insulate attic and walls to reduce heat gain (10-20% savings)
- Use reflective window films on west/south-facing windows
- Plant shade trees around outdoor unit
- Use thermal blinds to reduce heat penetration
- Seal door and window gaps
Troubleshooting Best Practices
- Keep AC manual and warranty documents accessible
- Note error codes and when they appear
- Document any unusual behavior or noises
- Call service for unusual issues (don't delay)
Upgrade Best Practices
- Replace ACs every 12-15 years (even if working—efficiency improves)
- Choose models with inverter technology
- Prefer R32 refrigerant over older types
- Look for 5-star rating for new purchases
Conclusion
Following these best practices ensures your AC runs efficiently, costs less, and lasts longer. Small consistent actions compound into major savings and improved comfort.
