Switch off the power supply.
Attic ac unit vibration.
I noticed a sound and it took some time to locate it.
High efficiency ac units incorporate sound dampening technology and two stage variable speed compressors to keep noise levels below 55 decibels.
I have a central air and gas heat unit in the attic no crawl space just a slab.
My old 28 years old unit made half the noise and had no vibration.
Climb up using a ladder and find the ac on the roof.
Buy four vibration pads one for each corner of the unit.
So if you hear unusual sounds coming from your air conditioner during normal operation don t ignore them as this could be a sign that the unit needs a repair or upgrade.
To reset the switch you ll need to climb up into.
The central air conditioner is by far the nosiest i have ever heard.
The ground around the outside unit actually shakes.
Here are some simple troubleshooting steps to fix vibration pads for removing vibration noise from air conditioning units that are roof mounted.
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 vibration can be heard inside and outside.
Measure and make a note of the width and length of the base of ac.
