With used units there are possibilities of several problems occurring, such as breakdowns and below par performance. An essential guide to purchasing a used unit is given below.
First, the main advantage with purchasing a second hand unit is the lower cost, as it will definitely cost less than purchasing a new one from a store. Many stores offer second hand units that have been replaced with newer units, or you can locate one that is advertised for sale in the newspaper.
For example, we found this refurbished Amana Reconditioned APN12J 12000 BTU Portable Air Conditioner on Amazon for a fraction of the price of the original one. So there are definitely deals to be had out there.
What are the problems associated with the purchase of a second hand unit? Warranties on second hand units are either non existent, or for a very short period of time. As a result if you encounter any issues with the unit, you will more than likely have to pay for the repairs yourself.
Hiring an expert to install a second hand unit can be quite difficult, as since they are not sure of the state or condition of the unit, they do not want to be blamed if the system does not function properly. This has happened on several occasions, where the installer after setting up the system, does not get paid because the unit was inoperable when received.
Parts for these units are also difficult to find, as technology, equipment and practices change as time progresses. Consequently, the system becomes outdated and the spare parts are costly and difficult to find.
The laws relating to the type of gases that can be used also change over time, so for older systems, it may actually be illegal to use the gases that they contain, as they may be harmful both to the ozone layer and to people.
