I would like to think the compressor is like the heart of the
airconditioning system. It circulates the hot and cold air to keep the room
cold.
So when it is spoiled.. what do you do?
It is not cheap to do a 'heart' operation - it can easily cost SGD1000
or more, depending on the brand, model and system of your AC.
So how do you decide?
First you got to be sure it is a compressor system. The findings of the
technician is likened to a doctor's diagnosis - you may want to seek a 2nd (or
even 3rd!) opinion or asked for a well qualified technician to confirm the
evaluation. So to be sure that the compressor is the problem and not something
else. You won't be too happy to know that you have spent thousands for a wrong
diagnosis.
So once you have confirmed it is the compressor issue, is it still under
warranty? Usually compressor are under warranty for a few good years. Check
your receipt / guarantee card.
And sometimes, you can change only the compressor, though you may want
to consider changing the full outdoor unit (ie the condenser unit). You would
want to have the expert's advice. And what about the cost of changing just the
compressor vs the whole outdoor unit?
Then with all the cost in, you may also want to consider changing the
wall mounted units as well - this will be a full AC replacement. First the cost
might not differ than much between just changing the outdoor unit vs changing
the full AC system. 2ndly the compressor may not operate at a optimized level
with a different AC unit it was created for. This will affect the efficiency
and the performance of the whole AC as a system.
So all in all, you may want to compare the costs after getting a full
diagnosis from a well qualified technician. This is not an easy decision to
make, but with the steps above, hopefully we have been of help!
Good luck!
