Buying an air conditioning unit is a significant investment costing up to thousands of dollars, with a lot of facets to consider. Now that you’ve decided on a split system, before you make your purchase, you need to figure out a few things.
First, you need to ensure that you choose a split system with an appropriate strength in kWs, which will best suit your space. Split systems come in different kW strengths. The most common strengths are: 2.5 kW (killowatts), 3.5 kW, 5 – 6 kW or 7-8 kW. To figure out which one is most suited not only will you need to consider the size of your space as above but also:
- The climate you live in (is it humid, dry, etc?)
- How big are the windows and doors in your space?
- Is the space open plan?
- Do your internal doors have any gaps allowing hot air from another room to infiltrate?
- Which way do your windows face? If it’s west you’ll need more power to compensate for the power of the summer sun.
- What kind of curtains, blinds, shutters, trees etc do you have?
- Do you have insulation?
If we break it down into room size, from smallest to largest:
- Small spaces/rooms (0 m2 – 15 m2); 2.5 kW is generally a good capacity for smaller spaces, say an inner city flat or small studio apartment. It should cover, for example, a bedroom or study
- Medium Rooms (15 m2 – 30 m2); In this size you’ll be looking at 3.5kW which should cover a bedroom with an ensuite, mid-sized kitchen or small lounge
- Large rooms (30 m2 – 45 m2) A 5-6 kW unit cover a large bedroom, mid-sized lounge or large kitchen
- Large open-plan space (45 m2 +); If you have a lot of space or are looking to cover an open plan area, you’ll be looking at a big 7 – 8 kW system to keep you cool.
The other critical point is to choose a top air conditioning installation company, who will install your unit correctly. A good installer can confidently talk you through any questions you might have, not only about installation but also your system and energy efficiency. Due to their knowledge and qualifications a top installer can provide the most appropriate system for your space. This includes systems that the installer can service and repair should something go wrong.
A good installer:
- Advises on the best system for you, your budget and your space
- Does work properly the first time
- Takes responsibility for their work
- Has good knowledge of the brands and manufacturers in order to pass on specials and promotions and ensure you’re choosing the best model for you
- Provides a clear quote with no hidden costs or extras
- Has the ability to service your air conditioner and clean the filters in the future
- Provides you with a thorough assessment that tells how long the installation process will take
- Is trained in the installation of the brands they prefer.
- They deliver clear information that lay people can understand. This helps us as consumers make an informed choice.
Other points to keep in mind:
- Don’t forget to consider operational costs. Air conditioning systems take up a fair amount of our utility bills. You can find a more energy efficient model by using the star system – the more stars, the more efficient (including models with a higher kW). That’s good news for your bank balance. The higher the quality, the higher the efficiency, so they are less expensive to operate and over time, they will pay for themselves.
- Placement and location of the unit is critical. It’s important to know the area where the equipment needs to be installed.
- Quality of air is very important when it comes to our health, comfort and well-being.
