Are central air condition units supposed to run constantly?
We just had a new Trane AC/Oil furnace combo installed and this is our first week of using the AC and it’s been running non-stop for about 6 hours now. We have it set to 75 and it’s around 90 degrees outside. Is this normal?
Also, it currently shows that it’s 77 inside even though it’s set to 75 and it’s been running for so long. In the winter, if we had the furnace set to 72 then it would keep the house at 72 no questions asked. Is the way a home heats up and cools down just different or is something wrong with our AC unit?
I tested the air and it’s blowing at 54 degrees so I don’t think that could be it. Also, our vents are on the ceiling instead of floor based and I’ve heard that homes with the air vents on the ceiling always take longer to heat/cool. Could that have anything to do with it?
Weather they should be running constantly or not depends on the unit. Mine goes on and off automatically, but yours might be set to constantly run. It may be doing this to keep it close to 75, since it’s so hot out, so it’s blowing enough cool air to keep it at the set level. Also, having the vents on the ceiling might affect something with the way air rises and sinks (hot air rises, cold air sinks), but I’m not sure if that’s affecting anything in your case. If you have a concern call the company who makes your unit.

What you describe DOES NOT sound "normal."
I suggest you call the company that installed it, explain the issue as you have done for us, and ask them to have a technician come check it out. I suspect that it’s still under warranty, and unless there is some "special" provision where you waived your warranty rights, and agreed to pay for service calls, then the "check-out" should be FREE.
