Rated 4.4 out of 5 by 47 reviewers.
Rated 3.0 out of 5.0 by Great mechanics, aesthetically challenged We are very pleased with the performance of this compressor. It is indeed very quiet and more than enough power to run the plasma cutter we use with it. We were disappointed at the quality control, however. The base of the compressor was chipped and poorly constructed, which makes us worry about the quality of the parts we can't see (photo attached). We aren't particularly concerned about a paint chip on the base but we are a little nervous how the rest of the compressor will last in the long term. I would suggest Home Depot work with the manufacturer on quality control since this damage did not happen in shipping. October 21, 2014
Rated 5.0 out of 5.0 by This product has great features. I needed a quieter compressor and this fits the bill. It is quiet enough that you can have a conversation right next to it while it is charging. It's great for blowing dust out of the garage and filling bicycle and other tires. Haven't tried it with a nail gun yet, but recharges in less than a minute. The aluminum tanks make me less worried about corrosion due to there always being water in the tank when I release the pressure at the end of the day. It have a very handy finger-switch for releasing the pressure. Much easier than the knurled fittings on most generators. I have it connected to a 50 retractable hose mounted to the ceiling. The compressor is small enough to fit under my workbench (picture). I couldn't be happier with this compressor. April 16, 2014
Rated 4.0 out of 5.0 by Good Air Compressor I did a lot of research and reading reviews before purchasing this compressor. If you are looking for a quiet compressor with great output in a carry size this is the one. It has aluminum tanks, weighs 64 lbs., a 70 db noise level and puts out 5.3 cfm @ 90 psi. Beware when moving the compressor, the tank drain will hit the resting surface (floor or tailgate) first, if lowered at an angle. Also the air filters protrude to the rear of the unit. I haven't owned this very long or used it much, but it fills very quickly and runs fairly quiet. I plan on using it with some air tools like an air chisel removing flooring in home remodeling. I would have given it five stars if the tank drain and filters were designed better. December 29, 2014
Rated 4.0 out of 5.0 by California Air 4620 Compressor Very quiet compressor. I hesitated to believe it would be so quiet, but it met my expectations for sure. They are pricey, but I felt worth the money. I have not used it much so I can not comment on long term quality. Definitely not built like a tank, but certainly not junk. Packaging was very good and there was no damage to the item. I would like to see a longer Warranty for that price however. March 24, 2015
Rated 1.0 out of 5.0 by poor quality with all the checking that I did about compressors I feel out in left field, all the problems were caused at the factory, broken weld, dented panel & a relieve valve that was bad. I returned it to HD and now I ordered another california comp. different style, hoping this one will come in good shape March 24, 2015
Rated 5.0 out of 5.0 by Fantastic Unit is compact and more then powerful to do everything I was hoping it would. Due to the size of the tank the motor will kick on regularly, though that is expected given the size of the tank. Primary use is for air nailers and dust removal prior to finishing wood projects. I can use the air sprayer at ~80PSI without fear of draining the tank and being left with what the motor is able to put out as the motor supplys air faster then I can drain it. Heatfins on top of motor are metal and do get hot with run time. I did originally have the 1hp version of this compressor, it was fine but due to some mechanical issue it needed replacement. I am glad I went with the 2hp motor as there are other upgraded components which instill a little more confidence with it's long term use, especially the massive size of the motor, large cooling fins, and improved air regulation going into the tank. It is noticeably heavier then the 1hp version. If I was to be moving it around much I would have stuck with the 1hp. February 26, 2015
Rated 5.0 out of 5.0 by very quiet perfect for in house use pump is very quiet, had a bad part, but company shipped replacement same day as reported problem works great, no other problems, hooked up and running in 5 minuets. February 27, 2015
Rated 5.0 out of 5.0 by Well Built and Quiet I just picked up the California Air Tools 4620 and I'm very happy with the purchase. The compressor came well packaged double boxed with sturdy styrofoam forms protecting key components. The pump feels lighter than the spec weight, probably because it is well balance and sturdy and easy to move with the handle. I started it up and two things caught my attention so I shut it off and phoned tech support. First item was a brass valve near the top of the motor seemed to leak a lot of air during startup. It turns out it's supposed to. That is the quick start valve that reduces initial startup compression up to about 20psi to reduce the initial load on the motor and more importantly the amps required during motor start. My second concern was the system pressure built rapidly right up to the redline, I was concerned it wouldn't stop at redline (120psi) so I shut it off. Larry at tech support said start it up and let it run it should stop at 120 psi with a pressure relief safety if it exceeds 125. I let it run it stopped right at 120. I guess I'm not used to home tools that are so precise. So much quieter and quicker than my old compressor. Great support from the manufacturer too. February 23, 2015
