Missing line driers - Any permanent damage?

I have 2 year old house with 2 Bryant A/C compressor units. One started making a noise earlier this year. It's hard to describe the noise but it's a throbbing low frequency noise. I had the pressure checked and he said it was at 3 when the unit specified 10. He wasn't sure what was causing the noise. He thought it could be the low pressure. He also said I was missing the line driers that are zip tied to every Bryant unit. He thought running a system for 2 years without them could also damage the units and be the cause of the noise but he wasn't sure.

So my question is can running an A/C unit for 2 years cause damage to the system? How likely is that to happen and what would be the most prominent symptoms?

I'm assuming they are there for a reason and not just for looks. I've got the original installers coming out in a few days to add the line driers that should have been there from day one. Should I have them do anything more then just adding the driers and then flush and charge the systems?

They are usually line dryers/filters. They remove the water from the refrigerant line while also trapping small particles of crap from getting to the compressor and the TXV. It's possible a piece of something got caught in the system.

We can't discuss charging procedures/pressures but yes..... the system will need to be emptied, flushed, a vacuum pulled and then a recharge.

Some, but not all condensers have the filter/dryer zip-tied down by the service valves. They can also be pre-installed within the condenser cabinet. Easy to see under the fan.
