Energy Saving Tips When Using Air Conditioning As A Heater

As autumn arrives, many in South Africa use their air conditioner system to heat homes and offices. This helps keep inside temperatures comfortable. But running the AC for heat can cost more money in energy bills if not done right. To save money on bills this autumn season, try the following energy saving tips when using your air conditioning unit.

Signs your Air Conditioning Unit is Wasting Energy

  • Significant energy usage spike resulting in high utility bills
  • Inconsistent temperatures
  • Poor indoor air quality
  • Long HVAC cycles

Get a Tune-Up Before Autumn

Before depending on your AC for heat, have our technicians service it. They will clean and inspect the air conditioning heating system. This ensures peak efficiency and finds any potential issues that could waste energy.

Use the Heat Pump Setting

Many AC units have a heat pump function built-in. Heat pumps take warm air from outside and move it indoors. This uses less energy than making heat from scratch and is more energy efficient than other heating options.

Regulate The Air Conditioner Temperature

This is vital for energy saving and efficiency when using your AC. The right temperature can strike a balance between comfort and energy efficiency. It will also help reduce the strain on your air conditioner, whether it’s summer or winter.

Seal Up Air Leaks

Seal cracks and openings around windows and doors. Air leaks allow heated indoor air to escape and cold outdoor air in, making your AC heat pump work harder. Closing all windows and doors when running your AC is recommended.

Open Curtains for Sun’s Warmth

During the day, open your curtains to let the natural light in through the windows. At night, close them to insulate against heat loss.

Change Air Filters Regularly

Dirty clogged air filters restrict airflow, causing your air conditioner to work harder when heating, wasting energy. Check and replace filters often for peak efficiency. Remember to regularly service your AC for optimal performance.


Following these energy saving tips for autumn AC heating can maximize your system’s efficiency. You’ll cut heating costs, extend your HVAC’s lifespan, and be more eco-friendly too! Give us a call at JC Refrigeration so we can get you sorted for winter!
