I live in a 28-unit condominium with a dry system that we agreed to have the valve & compressor replaced in September 2020. The previous system's air compressor ran 2 times every 24 hrs for 16 mins. The new air compressor ran every 4 minutes for 8 seconds & was very loud in an enclosed room. This new air compressor quit after 90 days & breaking at 2 separate times on the copper lines.
How can we cut down the noise and make repairs? As of today (March 2021), we have had a Cobalt compressor running in place of the general compressor that quit. The Cobalt runs every 70 minutes for 2.5 minutes. We are constantly told by contractor we have a leak somewhere that needs to be addressed, that we don’t doubt. We have cut the air off for a leak check, 2.5 hrs 2 lbs down. I know this lengthy but I need some advice how to cut down noise and repairs. Thanks for any help. Sent in anonymously for discussion.

First address the leak...no leak = less compressor time running.

I second Dan's recommendations regarding addressing the leak. If that continues to be ignored your will need to buy stock in compressor manufacturers. Additionally, the air compressor must be properly sized for the system installed as well so that it does not struggle trying to maintain any residual pressure loss. I have seen air compressors connected to an air reserve tank to help limit that amount of time the compressor cycles. Depending on the size of the system if its up to 300 gallons at 40 psi you can go with a the Gast model riser mount below. If you have a low pressure dry pipe system this compressor can handle a bit more volume. This will be at 63 dB, and you can add another sound kit for it to reduce the dB up to 25% more which makes it the quietest on the market.

I also agree with Mr. Wilder. Address the leak first. Compressor shouldn't be running that much. Look at the simple area using soap and water and look for it. If that does not work, hydro test the system using scented solution that will aid you in find the leak. Once you find the leak and the problem continues after a period of time check the system for internal pipe damage. The pipes may be getting corrosion and causing small leaks to occur.
