Air conditioning works using the same principals as your refrigerator. This is done via the vapour compression cycle where refrigerant is manipulated into changing states from liquid to vapour at different parts of the cycle to enhance heat (energy) collection and rejection.

Every situation is different. A lot of the time it is a case of balancing between getting the best system you can whilst suiting your budget. Other factors can be physical restrictions (sometimes a ducted system simply won’t fit in the roof). We experienced all types of situations and can advise on what your best options are.

Generally, this depends on how often you use it. Normally, a household unit will need servicing once a year. However, with regular use then this should be twice a year. Commercial situations should be services quarterly.

The simple answer to this is ‘yes’. However, modern systems are inverter driven. This means that it will increase and decrease the power consumption according to the demand. Other factors also affect how much it costs to run. These are:

• Close windows and doors to outside.
• Operate at a higher temperature and allow more continuous running instead of regular switching on and off.
• Remember to switch it off when you go out and use the timer when you go to bed.
• Child lock……say no more!

 All our equipment comes with a 5-year warranty. However, most system should last for about 15 years. Normally the determining factor for a unit becoming un-workable is because the manufacturer no longer stocks the component parts for that particular system.

Regardless of which manufacturer you choose, if you buy a unit that says it will do 15 kw then that is what you will get. However, there are several other factors:

• Quieter operation.
• More control options.
• Higher efficiency.
• More reliable.
• Less subjective to corrosion.

Units installed within 2 km of the coast are much more likely to be subject to corrosion from salt in the air. We can provide an additional spray to the outdoor unit. This will provide an extra 4 years of life extension on the exposed components.
