Recommended Materials

You also need top-notch DIY aircon materials. They’re key for a safe and efficient installation:

Choose materials that meet Australian standards. The right tools and materials set your DIY air conditioning project up for success. It will cool your home effectively for years.

Choosing the Right Location for Your Air Conditioner

Getting the best from your aircon starts with where you place it. Making sure it’s in the right spot means it will work better and last longer. Here’s what to think about for setting it up inside and outside your home.

Indoor Placement

Inside, picking where to put your air conditioner is key. Look for a central area away from the sun and things that might block the air, like furniture or curtains. This helps it not to work too hard and keeps the air moving well, which makes it cool more efficiently. Avoid putting it near devices that heat up or in rooms you use a lot, as this affects how well it works and uses more energy.

Outdoor Placement

Choosing the right spot for your outdoor unit matters too. Place it where there’s lots of space away from plants, trees, and rubbish. This makes it easier to look after and protects it from damage. Don’t put it right under edges of your roof or where water stands. Having enough space around it is key for the best cooling and to help it last longer.
