Attic Ac Unit Vibration

Switch off the power supply.

Attic ac unit vibration.

The vibration can be heard inside and outside. The central air conditioner is by far the nosiest i have ever heard. 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. To reset the switch you ll need to climb up into.

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. I have a central air and gas heat unit in the attic no crawl space just a slab. Climb up using a ladder and find the ac on the roof. Measure and make a note of the width and length of the base of ac.

The ground around the outside unit actually shakes. My old 28 years old unit made half the noise and had no vibration. I noticed a sound and it took some time to locate it. 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. 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.
