How to Keep Your Air Conditioning Running Smoothly During a Heatwave

Melbourne summers are known for their intense heatwaves, and during these times, your air conditioning system becomes your best friend. However, the increased demand can put significant strain on your system, potentially leading to inefficiencies or breakdowns when you need it the most. To help you stay cool and comfortable, here’s a comprehensive guide on how to keep your air conditioning running smoothly during a heatwave.

‍

1. Schedule Pre-Summer Maintenance

Preventative maintenance is the most effective way to ensure your air conditioning system operates efficiently during a heatwave. Schedule a professional servicing before the summer begins to:

• Clean or replace air filters.
• Check refrigerant levels.
• Inspect and clean the coils.
• Test the thermostat for accuracy.

A well-maintained system not only performs better but also uses less energy, reducing your electricity bills.

‍

2. Clean and Replace Air Filters Regularly

Clogged or dirty air filters restrict airflow, making your system work harder and less efficiently. During a heatwave, check your filters more frequently, especially if:

• You’ve been using your air conditioner heavily.
• You have pets or live in a dusty area.

Replace or clean filters every 1-3 months to maintain optimal airflow and cooling performance.

‍

3. Ensure Proper Ventilation and Airflow

Blocked vents or furniture placed in front of air registers can obstruct airflow, reducing your system’s efficiency. Keep all vents clear and:

• Open interior doors to allow air circulation.
• Ensure the outdoor unit is free from debris like leaves or dirt.
• Avoid placing items on or near the outdoor unit.

For split systems, ensure the indoor unit has unobstructed airflow.

‍

4. Set the Thermostat Correctly

Your thermostat settings can greatly impact your air conditioner’s efficiency during a heatwave. Follow these tips:

• Set the temperature to a comfortable level, such as 24°C-26°C. Avoid overcooling, as it increases energy consumption and strain on the system.
• Use a programmable or smart thermostat to automatically adjust temperatures when you’re away.
• Avoid setting the thermostat too low immediately—it won’t cool your home faster but will increase energy use.

‍

5. Use Ceiling Fans to Support Cooling

Ceiling fans can enhance the cooling effect by circulating air, allowing you to set your thermostat a few degrees higher without sacrificing comfort. Use fans in conjunction with your air conditioner to:

• Improve airflow throughout the room.
• Reduce the load on your air conditioning system.

Remember to turn fans off when leaving the room to save energy.

‍

6. Seal Windows and Doors

Preventing hot air from entering your home is essential during a heatwave. Seal any gaps around windows and doors using weather stripping or caulking. Additionally:

• Close curtains or blinds during the hottest part of the day to block out sunlight.
• Consider using reflective window films to reduce heat gain.

These steps help your air conditioner work more efficiently by reducing the heat load inside your home.

‍

7. Avoid Overloading the System

Running your air conditioner at full capacity for extended periods can strain the system. To avoid overloading:

• Use cooling in specific zones if your system supports zoning.
• Limit the use of heat-producing appliances like ovens and dryers during the hottest parts of the day.
• Turn off the air conditioner when leaving the house for an extended period, or use the "eco mode" if available.

‍

8. Check Refrigerant Levels

Low refrigerant levels can cause your air conditioner to operate inefficiently or even damage the system. Signs of low refrigerant include:

• Warm air blowing from the vents.
• Ice forming on the evaporator coil.
• Unusually high electricity bills.

A professional technician can check and top up your refrigerant levels if necessary.

‍

9. Invest in Smart Technology

Smart thermostats and monitoring systems allow you to optimise your air conditioner’s performance during a heatwave. Features include:

• Remote control of your system via a smartphone app.
• Automated scheduling to reduce energy use during peak hours.
• Alerts for maintenance issues or unusual performance.

Brands like Daikin and Mitsubishi Electric offer air conditioners with smart features to enhance efficiency and convenience.

‍

10. Plan for Professional Servicing

Even with regular maintenance, heavy use during a heatwave can strain your system. Schedule a mid-summer check-up if you notice:

• Unusual noises from the unit.
• Inconsistent cooling or weak airflow.
• Increased energy consumption.

Professional servicing ensures your system remains in top condition throughout the summer.

FAQ: Keeping Your Air Conditioning Running During a Heatwave

Q1: How often should I clean my air conditioner filters during a heatwave?

Clean or replace filters every 1-3 months, or more frequently if usage is high.

Q2: Can running my air conditioner continuously damage it?

Continuous operation can strain the system, so use zoning or set a moderate temperature to reduce the load.

Q3: What temperature should I set my air conditioner during a heatwave?

Set your thermostat between 24°C and 26°C for optimal comfort and efficiency.

Q4: How can I tell if my air conditioner needs servicing?

Signs include reduced cooling efficiency, unusual noises, or higher electricity bills.

Q5: What’s the best way to cool my home during a heatwave?

Combine your air conditioner with ceiling fans, seal gaps, and block sunlight to reduce the heat load.
