air conditioning

I don't use air conditioning a lot.  Cost is a factor but also the fact that when you turn on the air conditioner the outside world becomes a hostile environment and you are likely to stay inside.  Also, the environmental impact is a consideration.

There are some really hot days and nights when even I turn on the air.  The first such hot night this summer I turned on the air conditioning and it blew warm air.

I spent the next day doing research on the internet and using my meter to try to track down the problem.  I couldn't find the problem.

 When all was said and done it turned out that I had a leaking valve on the outdoor unit ( the compressor and condensor ) and all freon had escaped from the unit.  $450.00 dollars later the air conditioning is working.  I hope that the fix lasts a long time the replacement cost is very high.
