My 8gal compressor was running the entire time and I’d only get a few passes before I didn’t have enough pressure to get the pint out.

I think on my last one that someone busted the line to the compressor it cost me almost $200 for everything.

He told me that lightning was the reason for the failure in this case and as a result it would cost $500 for both the labor and new compressor (under warranty with the unit).   

. ($80)If he messes around at all with granite or marble slab, a Makita wet stone polisher ($300)If he does wood flooring, pneumatic Bostich Mark IIIFN (Flooring Nailer) ($350)For that matter,the right 16-gauge manual nailer (Bostich MFN-201) ($220)Any sort of roofing, buy him a heavy-duty climbing harness ($100)Good sized air compressor for woodworking and painting ($200)If he does tile, he likely has a big 10-inch tile saw with a sliding table, but he'll still appreciate a more mobile Ridgid 7-inch saw of the same basic design.

A compressor hose and shingle gun as well as a roof spade will get most of your needs.

If OP doesn't have that problem...then we're all good.By the way, off topic, just picked up the Xotic Compressor pedal yesterday and adding it to my board tonight.

A pressure test is a compressor setup and run through the system and you go hunt down the leak.

New compressor and unit can easily run around 10k. 

I went with the $3500200amp service is more than enough for most normal houses The 1630 sq ft house has an additional 960 sq ft shop in the back with AC, Bathroom, compressors, and was used to renovate automobiles. 

He also tells me a compressor went out on an ac unit which I would never have known had I not asked if anything else happened.
