Our 06 FF T160 roof air unit has been noisy and vibrating since we got it. This week my youngest son, an HVAC pro dove into it and found dirt dobber nests n other debris in n on the fan under the cover on the roof. He also did some additional sealing, clean coil n evap which were filthy. Fired it up and lot less noise and zero vibrations. He said just the slightest thing on the fan will throw it out of balance, thus vibrations.
Air conditioners do need routine maintenance. Glad he did it for you. Easy to forget about them.
