Natural ventilation

Create cross-ventilation by opening windows on opposite sides of your home. This allows fresh air to flow through, cooling down the space without relying solely on your air conditioner.

Ensure that window screens are clean and in good repair to keep out insects and debris, allowing for uninterrupted airflow.

Additionally, consider installing a skylight or roof vent to release hot air from the top of your house, drawing cooler air in through lower windows. This can be especially useful during summer months when heat tends to accumulate near the ceiling.


When considering how to maximise the efficiency of your air conditioner, it’s important to pay attention to insulation. Proper insulation helps in maintaining a consistent temperature within your home, reducing the load on your air conditioning system and ultimately saving energy and costs.

Insulated walls, ceilings, floors, and ductwork can prevent heat from seeping into your home during hot weather and keep the cool air inside where it belongs. Good insulation is key to creating an environment that is easier for your air conditioner to cool efficiently while keeping you comfortable.

Insulation plays a crucial role in maintaining a comfortable indoor environment during extreme temperatures. It prevents cooled or heated air from escaping outside and helps maintain a stable temperature indoors without overworking your air conditioning system.

Night-time cooling strategies

During the night, keep your home comfortable without overworking your air conditioner. Here are some strategies to help you beat the heat and sleep better:

  1. Open windows strategically to let in cool air.
