Can you take the temp at the return air (air filter) and take the temp at a supply air grill in the ceiling or floor witch ever you have, If your high limit switch was tripped it may just be that, it protects your compressor, it may have a red button re-set you can re-set !

I don't think ours has a reset button. At least, I've never seen one. We checked inside the unit, and we're not getting any error codes (little red flashing LED). It's blinking slowly, which indicates normal operation. It would flash four times if there was a problem with the limit switch. I remember that, because we had to replace the limit switch in the dead of winter about five years ago when all of a sudden we had no heat. It was an easy fix. I just hope we get that lucky this time. Thanks for the suggestion.

But, but, what if we don't hear from you?

Seriously, good luck with that. When you said "BOOM" you didn't actually mean it went BOOM, did you?

If you don't hear from us, well... :dontknow:
And no, it didn't actually go "BOOM" Although, with everything else going wrong around here, it wouldn't surprise me.

And this is why I installed a sight glass on my liquid line near the air handler. Don't have to guess if it has a low charge, etc.. I can just look.

If this does turn out to be a low freon issue, I think we are going to borrow your example and do the same thing. Thanks for the suggestion.

That blows. Sorry for the poor joke.

Our central air went out last year. Frank and John were both very generous and gave us a window unit each. That is still how we are staying cool. Two 5K units cooling about 1K sq ft. Takes a while but it gets it there. We just leave them running. Our furnace bit the dust in January. I have not ventured to see what's goin on there. I guess I need to before long. lol

Hopefully you will get it goin. I wish I was closer. I don't have a lot of HVAC experience but we could drink some beer and just stare at it together.

You crack me up, Rob! I needed the laugh, thanks.
