Choosing the Right Air Conditioner for a Queensland Home

Advice from DHG Electrical Services

Cooling for the Queensland climate

Summers in Brisbane and Moreton Bay are hot and humid, so a good air conditioner is not a luxury, it is how you stay comfortable. But picking the wrong unit or the wrong size wastes money and leaves you sweating. Here is what to think about.

Getting the size right

Size is the single most important thing. An undersized unit runs flat out and never quite cools the room. An oversized one cools too fast, cycles on and off, and does a poor job of pulling humidity out of the air. The right size depends on:

  • The size of the room or home
  • Ceiling height and insulation
  • Window size and which way they face
  • How many people usually use the space

In our humid climate, controlling humidity matters as much as temperature. A correctly sized unit does both.

Split system or ducted?

Split systems

A split system cools one room or area. They are cost effective, efficient and great for bedrooms, living rooms or a home office. You can add more units over time as your budget allows.

Ducted systems

Ducted air con cools the whole home through vents in the ceiling, controlled by zones. It costs more upfront and needs roof space, but it is neat, quiet and ideal if you want even comfort throughout the house. Zoning lets you cool only the rooms you are using.

For many Queensland homes, a mix works well: ducted for the main living areas or a couple of well-placed splits for the rooms you use most.

Efficiency saves you money

Air con is one of the biggest power users in a Queensland home. A higher efficiency unit costs a bit more to buy but less to run, which adds up over those long hot summers. If you have solar, running your air con during the day makes even more sense.

Get it installed by a licensed pro

Air conditioning install involves both electrical and refrigerant work, so it must be done by a licensed installer. DHG Electrical Services holds an ARC refrigeration licence (L186689) as well as our electrical contractor licence, so your system is installed safely and legally.
