Hey guys
I'm a first-time home buyer and unfortunately seem to be running into central air unit problems.
I've taken a video of both problems.
The first one can be summarized as sometimes the AC unit will sound fine, then every 30-45 seconds will start to make a slight buzzing sound that builds up into a loud click. The fan also slows down at this point, then speeds back up. A video of this problem is here: Slight buzz and loud clicking noise on Tempstar unit - YouTube
The second problem is a constant buzzing sound. Every few minutes the sound will stop for a few seconds, but always comes back. That can be viewed on this video: Buzzing sound from Tempstar AC unit - YouTube
At first I noticed the buzzing sound. After turning the unit off then back on after some time, I noticed the buzz/clicking sound. Turning the unit back off and turning on the heat to test it out, then back on to the cooling, the unit seems to work fine, but the buzzing sound was.
If anyone has any advice, that'd be greatly appreciated!

You sir have a major compressor issue.... time to call a professional. There is nothing that I can recommend a homeowner do with those types of noises/issues.
Welcome to the forums.
In your fist video the fan sounds normal and that click sounds like a contactor chattering or an issue with the reversing valve.
In the second video it sounds like your fan motor is squealing. The fan is mounted upside down to the very top of the unit.....does that sound like where that noise is coming from ?
Quick update in case anyone in the future finds this thread with similar problems...
Short version: a coil broke causing an oil leak, or it may have been the other way around. That's what ultimately caused the AC unit's fan to stop turning on.
Long version: the a/c unit was extremely dirty, causing poor air circulation. This led to a coil breaking/oil leak, which then caused an oil leak/coil breaking, depending on which came first.
Home warranty covered the repair, only because (from my understanding) our AC wasn't inspected by the home inspector, therefore there was no evidence of what caused the oil leak nor whether it was there before purchase or not. It started breaking three days after closing on the house, and the first three days in the house we had air conditioning. That much I know. The repairman's best guess was the dirty unit caused the issue, but that isn't for sure.
Lessons learned: make sure the AC unit gets inspected before moving into a new home, and clean your AC unit (I sprayed mine with a hose and it made a big difference) regularly.
