I have been working on the cost estimates for some time and right now we are doing the work on the air conditioning. That is going to be a big deal to be honest and we are not yet sure how we are going to play it. I have to talk to the people from aircon servicing and they are going to give me a couple of different prices. Of course there is the big ticket for the whole thing. You would have to rip out what you have and replace it with a whole new system. The thinking is that it would be the best deal in the long haul, but of course you have to put up a whole lot of money in the here and now to do that. So it might not be something which can be done without breaking the bank. It is what we have to figure out obviously.
The other option is to figure out if the system can be fixed up in a way that makes sense. That has obvious benefits in that you are hopefully going to need much less money up front. The down side of it is that you could quite easily end up accomplishing almost nothing. If you patch it up it is still going to be old and inefficient. The system will be quite likely to need to be fixed again, the question is whether or not you would be able to gain a lot of time from it. If you could not get the right amount of benefit from it, then the whole thing is a big waste of money. You are merely throwing good money after bad as the old saying goes. It would be a big risk to do it like that obviously it seems.
