I have it installed in the pump room outside my garage and it still is loud enough to disturb any conversation going on in the garage.
BUT- I have had my compressor for 8 years (it was my wife's first x-mas gift to me!!) and with little to no maintenance (I know, I know!). it runs all my tools with no problem. but it is hooked inline to a 80 gallon air tank with a bad motor for reserve air supply,too!

Not saying that CH is junk, will probably work fine if this is just a home use (light duty)compressor. Now if you plan on restoring cars/trucks for a living out of your home, by all means buy an industral air compressor(Gardner Denver, Sullair, IR, Quincy)this is something you are going to run 5 days a week.
To have a good supply of air for just about whatever you want to run, an air compressor sould put out at least 13 to 16 cfm @ 90 psi. 90 psi is where most air tools are rated for air consumption and rated output.

running a compressor past its duty cycle shortens the pumps life, like pulling too much weight behind a truck.

Well I ordered my compressor today..After about 6 hours of online work I got what I think is the best for the money..5hp 20 cfm at 100 psi 19 cfm at 175..20,000 hour rated life...Supposed to be super industrial...Its called Devair made in canada..If my current setup will drive it ok amperage wise I may consider getting a 7.5 hp motor off ebay and a diff pulley and go with that at a later time.

A Sullair will give you better performance than any IR. We have a Sullair at work for the main air system and several old CH's that the maintenance guy ripped the pump and motor from and piped the Sullair into the CH tanks and placed these in various places throughout the plant, so high use areas will have a reserve of air.

There is an immense difference between the industrial duty air compressors and the hardware variety. I/R makes both kinds and you just cannot compare the two types. I have spent a lifetime working on compressed air equipment and can tell you that I/R, Sullair, G/D, Quincy, LeRoi are all excellant machines. The only real difference between them is the quality of their controls. If they weren't good they wouldn't be so popular. You do get what you pay for.

All the big industral air compressor manufactures compressors are all in the ball park. They have to be it is a very competitive buiness. Comes down to features, packaging and price.
