Saving Tips - Choosing the right air-conditioner

Recently, the air-conditioner at my house has just broken down. It has served our family well for nearly eight years. So now I have to go and scout for another air-conditioner unit. There are several things that we have to consider when buying an air-conditioner such as
1) The cost of the air-conditioner

2) The operating cost of the air-conditioner

3) Warranty Cost of the air-conditioner
The cost and the operating cost will depend on the type of air-conditioner that you are buying (non-inverter or inverter). For non-inverter, the cost of the air-conditioner is much lower than that of the inverter type. But for non-inverter, the operating cost of the air-conditioner will be much higher. Before you decide whether to buy the inverter or non-inverter type, you must first understand your needs. Do you switch on the air-conditioner on everyday? How long a day does the air-conditioner run. If you switch on the air-conditioner on a daily basis, it will must cheaper to buy the inverter type as the operating cost will be lower and in long run, you will save more. Especially with the raising electricity tariff, it will be a much better bet to buy a more energy saving air-conditioner.
I think everybody will be quite confused regarding the extended warranty and servicing package being offer by the merchant when you purchase the air-conditioner. For most air-conditioner, the warranty of the unit comes with two parts
1) Compressor Unit

2) Others Misc. Parts
Normally the manufacturer gives a 5 year warranty for the Compressor Unit and a year warranty for the other parts. You can take up the extended warranty package (4 year for the other parts) from the agent. If you take up the extended warranty package, you will have 5 year warranty for the whole air-conditioner unit. But whether to take up the extended warranty will greatly depend on individual.
As for the servicing package, each servicing will cost around $75 to $120 depending on the agent that you purchase from. How often you want to service your air-conditioner will also depend on individual. But do take note that regular servicing will improve the efficiency of the air-conditioner thus saving on the energy consumptions.
