Today, almost every household and office has installed an aircon unit. Air conditioning has become such as integral part in our lives, even though we do not give much thought to it. Whenever you are out shopping, all the centres will surely be air-conditioned. Whenever the weather gets hot, you will be desperately looking for air-conditioning place to cool yourself.

As we are now overly-dependent on air conditioning, sometimes aircon contractors use this opportunity to maximize their profits in unethical ways. So, let me share with you 3 things to look out for when you are hiring an aircon contractor:

1.Make sure that the contractor cleans your air conditioner in the right way by using the right chemicals. There are harmful moulds growing in your air conditioner fan coils. When the contractor cleans your fan coils with a brush or vacuum, they loosen these spores from the fan coil units. These loosened mould spores will be blown into the air and you will breathe into your lungs. This is extremely harmful to your health and you need to make sure that your contractor does not do this. Always ask for the right types of cleaning chemical to be used when cleaning your air conditioning unit. Sometimes, the contractor may not want to use it because he wants to maintain his bottom line. This is also part of his strategy to get more service jobs out of you.

2.Always insist on at least a 1/2 inch drainage pipe for split unit air conditioning. If your contractor tells you otherwise, you need to beware. Sometimes, the contractor may just give you an undersized drainage pipe so that the pipe will choke. This will cause the unit to leak easily and thus require you to call for service often. So always insist on a large enough drainage pipe to be used.

3.Always check the full range of service offered by aircon contractors. One trick many contractors use is to offer relatively low cost for their annual servicing contracts, which they will use brushing and vacuuming method to service your aircon unit. As I have mentioned before, brushing and vacuuming are not enough and they can be harmful to your health if not done properly. Usually by the second servicing, you will complain about low performance of your aircon unit. Upon this time, your contractor will recommend a full chemical service. A full chemical service is very expensive, and since you have already committed to the contractor for a year, you will agree to the full service to get back the strong clean air as before. So, make sure you know exactly what they are offering for their annual package and ensure that they clean with the right methods to preserve the useful lifespan of your air conditioning unit.

Keep yourself up to date by doing a research on the Internet to find out the right way to clean. In this case, you will prevent yourself from falling into victim into these unethical contractors' plans.
