Freon CheckIt all started with me sleeping on the sofa, my A/C unit broke. I had the service guy come three times and I am losing trust in my air conditioner, for obvious reasons.

The first time, I was told that the Freon level was overcharged. Meaning, the fan was on, but the compressor shut off cause it was "over charged". Supposedly, putting too much freon in the air conditioner will overcharge the compressor and it won't cool the house. Having too little freon will cause the compression not to cool the house as well.

So when they came the first time, they adjusted those levels. But they didn't do it 100% correctly. So they came back two days later to re-level the freon. Now, a week and a half later, I had them come back again. This time, the A/C unit worked for them when they came back. He did nothing to the freon levels.

He did say that the Freon levels are "almost perfect" and now that it is working, he doesn't want to change them. If it stops working again, call him and they will come back and adjust the levels slightly to make them 100% perfect. He also suggested that they might move the thermostat - but he doesn't think that is the issue.

So now, I am in wait mode. Wait for it to fail to call them back so they can play with it again. Not 100% happy but it could be worse, a lot worse - I do have it good.

How do they test Freon levels? The picture above from this site shows exactly what the AC guy was doing. The tank hooks up to those pressure gauges, which hooks up to the AC unit, somewhere. The pressure gauges tell you if the levels are proper. Supposedly, it is good to get those levels before every season.
