Need To Know's About Air Conditioning Installation

Choosing the correct air conditioning system for your space will ensure maximum energy efficiency. Choosing the wrong system could cost you a fortune because of short cycling (The unit continuously turns off and on).
Some units use more power than required because of inefficient manufacturing and technology. Always choose a Japanese made manufacturer to avoid expensive costs.
Air conditioning systems use the energy efficiency star rating system in Australia governed by MEPS an independent testing organisation.
Some AC systems can be rated as high as ten stars on the Energy Efficiency Star Rating with the new “super efficiency ratings”.
Blue coloured star rating labels are for cooling, and red coloured star ratings are for heating.
Keeping your air conditioner's filters clean will reduce the operating costs of the AC by up to 15%. Servicing your unit every six months will reduce your running costs and will maintain the manufacturer's warranty.
