My bed is near the wall and when i put my ear on the wall i hear the sound created by the slightly vibrating or normal operation of the unit.
Attic ac unit vibration.
Assuming this vibration noise occurs only when the a c is running which should be real easy to check out and you cannot find loose mounting bolts or loose metal ducting thgat is vibrating then you should not quit using the unit and call a heating and a c tech to check it out.
The central air conditioner is by far the nosiest i have ever heard.
To reset the switch you ll need to climb up into.
Switch off the power supply.
Measure and make a note of the width and length of the base of ac.
The vibration can be heard inside and outside.
Climb up using a ladder and find the ac on the roof.
Bryant has changed the unit and this second unit is just as nosier.
I have a central air and gas heat unit in the attic no crawl space just a slab.
In addition to making the unit hard to get to for service high attic heat can trigger the high pressure limit switch turning your condenser off.
Buy four vibration pads one for each corner of the unit.
I noticed a sound and it took some time to locate it.
My old 28 years old unit made half the noise and had no vibration.
Here are some simple troubleshooting steps to fix vibration pads for removing vibration noise from air conditioning units that are roof mounted.
