Attic Ac Unit Vibration

Here are some simple troubleshooting steps to fix vibration pads for removing vibration noise from air conditioning units that are roof mounted.

Attic ac unit vibration. I noticed a sound and it took some time to locate it. Measure and make a note of the width and length of the base of ac. Switch off the power supply. High efficiency ac units incorporate sound dampening technology and two stage variable speed compressors to keep noise levels below 55 decibels.

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. My old 28 years old unit made half the noise and had no vibration. The vibration can be heard inside and outside.

Buy four vibration pads one for each corner of the unit. 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. 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. Bryant has changed the unit and this second unit is just as nosier.

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. The central air conditioner is by far the nosiest i have ever heard.
