Be warned, the Porter Cable service policy as stated in the manual is essentially: Don't return a defective unit to the retailer. Call Porter Cable to find the nearest service center. You pay the shipping(not cheap on a 130 pound compressor).

This time I installed the compressor with the air hose reel from Amazon mounted right beside it on the floor. If you get the reel, you'll probably need to make a trip to the local hardware store for an interconnecting piece to connect the reel to the compressor. I now use the pancake style as the portable one (I agree, this one's too heavy).
Don't know yet - I spoke with the owner of the company, Kim Allen, and he said that I would need to have it repaired under the warranty. After several calls to the toll-free number in the manual to the factory, I was put in touch with a repair facility an hour away and was told they don't stock the part but could order it and get it back to me in a few days.

This whole situation did not sound like the legendary customer service Porter Cable is known for. I contacted Porter Cable customer service and was told there is no reason why Kimco should not replace the unit - in fact, the very helpful customer service rep even explained that Porter Cable would pick up the return shipping costs.

I am now waiting for Kimco's Porter Cable rep, Jim White, to return my call. Hopefully, PC will come though without me spending four round trip hours and a week without a compressor.
Frustrated with the technical assistance - When I bought my CPF23400S, I did it because I saw some good comments about Porter Cable equipments, and most important, they have a lot of places for technical assistance.
I received my compressor and unpack it. So, I went to my computer and by internet, on Porter Cable website, I found a authorized service center close to my house (Willie's Small Engine - Pompano Beach, FL). I went there with the compressor and they took it and said to leave it there for one day, and on the next day they should call me to pick it up. But, after 3 days, they still didn't have changed the little tank pressure gauge, and they said "we are waiting for Porter Cable to send this piece to us, you have to wait until next week". Ohhh! Come on!!!
I can't believe that! The most common and cheap part of a compressor they don't have in stock!?
Is that kind of technical assistance we have from Porter Cable when we just buy a brand new compressor and need it working???
I think I should send it back and bought another from another company, because, now, I'm just waiting and I can't do my job.
Porter Cable Compressor Review - My compressor arrived about 7 days after I placed my order. Keep in mind that your compressor does'nt include a hose, fittings, or a filter which is a good idea to extend the life of your air tools and a must to spray paint, so these items must be purchased seperatly. It's not too loud, it can fill up fairly quick, and most of all it provided plenty of power for what I was using it for, even when using a 100 foot extension cord. I am happy with the performance of my Porter Cable and would recommend it to anyone.
A powerful ,compact compressor/reasonably priced!!! - I purchased this compressor for my crew of six men after I read the other reviews on the tool crib website. I am very impressed with the capabilities of this lightweight/powerful and relatively inexpensive compressor. As with all Porter Cable tools it is well designed, strongly constructed and built to LAST !! I especially like the two built in quick connects and the power to run two framing nailers at once from a small and easily transportable package. I highly recommend this product to anyone looking for a powerful, compact and one man transportable compressor. Three cheers and a Hoopla to Porter Cable on this one.
What a great little compressor - This little compressor is a real gem. This task has not strained my Porter-Cable at all.
Plenty of Power to Offer...but it needs plenty, too. - I tried the compressor on an
undedicated 15 amp circuit, and it immediately blew the switch every
time. I called Porter Cable and they admitted this 3HP motor NEEDS A
DICATED 15AMP CIRCUIT (with nothing else on the circuit to compete).
I also learned (the hard way, of course) that if you are using the
compressor with a 50' extension chord (with too high a guage) on a 20
amp circuit, the pump will not get enough electricity to pump air
after cutting-in when the tank pressure drops to 110 psi (the
specified cut-in pressure) - the pump will start pumping, but quickly
stop and you'll hear the motor straining until it blows the 20 amp
circuit, too. Porter Cable told me that if I plan to use even a 20
amp circuit with an extension chord, I need to use a 12 (preferable
10) gauge extention chord (ideally 25' rather than 50'), or the pump
won't get enough juice to cut-in properly and refill the tanks. It's
cheaper, my new Porter Cable friends say, to buy more air hose than
the right gauge extention chord - Ah, such knowledge I'm gaining.
Sadly, the compressor arrived with an air intake filter housing badly
bent downward (done apparently at the factory, as the box from Amazon
wasn't damaged), so I couldn't remove the air filter. AND, the drain
valve (to drain water from the bottom of the tank) would not
completely close allowing lots of air to excape from the tank. In my
chats with an Amazon tool sales rep, and later with a Porter Cable
tech rep (to help me unravel the compressor's electrical-needs
mysteries), both Companies quickly and nicely insisted on sending me a
new air intake filter housing and a new drain valve (I guess I'm
getting two of each?) - no questions asked. The machine is fairly
loud, but it only takes my pump about 6 seconds to refill the tanks
from the 110 psi cut-in pressure to the specified 135 psi cut-out
pressure. I figure the noise level goes hand-in-hand with the added
power this compressor offers - power I think I need.
portercable compressor - This is a very good air compressor. I run multi-equipment from my air compressor every day. I will buy another porter cable compressor just like the one I have now but it still works like brand new so I dont see having to replace it in the near future.
Fantastic Compressor - I do crafts and wanted a compressor to replace my old one when it died. I was told by others that none of these smaller compressors would do that. It drove my Porter Cable narrow crown stapler with long runs before having to build more pressure. No problem ! ! ! I could get most of the nuts off of one tire before the compressor would come on again. Perhaps this compressor wouldn't do for a mechanic, but for someone who changes their own tires, it does just fine. It is noisy, but I don't think any more so than any other compressor.
Great little air compressor - This air compressor is great! This unit is fairly quiet, compact, light enough to be toted around if needed, no oil needed and very powerful. This unit replaced a 12 year old 15 gallons, 2 hp, craftsman rolling air compressor and all I can say is that I wish I purchased this unit sooner. When comparing the 2 units the Porter Cable is definitely stronger, the only difference being that when you are running any tools the compressor is running almost non stop compared to a unit with a larger tank that does not have to refill as fast. I consider this a plus though, because I always drain the tank after each use and it does not take as long to release all the air. At this price range there are many choices out there for anyone looking for a compact air compressor but when you start to compare CFM ratings @ 90 PSI this one has the highest ratings.
Great for various air tools - Just for little bit more of money, it is much better equipment than a pancake version.

Size of the tank is fine, but its really about the horsepower of the motor and amount of air motor can put out so that you don't have long period of motor running in order to build a pressure in the tank.
Excellent compressor - quietest I've used in its category - I am never able to live without a good air compressor. I use them for a variety of tasks from simple blowing to nailers and air hammers. As smaller air compressors go, this one really delivers a nice, steady pressure for quite a long time.

Normally I like to blow through my air gun at about 50psi to clear sawdust. Blowing air at that pressure really drains a small compressor fast, but this one really handles it well and gives me quite a bit of extra time due to the fact that the motor really kicks in quickly and efficiently to keep the pressure up.

I couldn't outpace the compressor with a single nailer.

The two air ports is really nice in one this size because I can put the compressor underneath my workbench and mount a static line on my workbench for easy access anytime while leaving the other open for longer hoses. These size compressors can make an INCREDIBLE amount of noise, but the Porter-Cable 3hp 4 gallon side stack really keeps the noise level at a minimum.

Don't hesitate in making this a must have purchase for your shop!.
Great Package - The pancake compressor powers all my nailers to drive 16d's at 120 psi all the way down to 3/4" brads at 30 psi. The compressor is easy to move which makes the upstairs finish work much easier. The finish nailer is a quality tool, its a Porter-Cable. Even having to buy a new hose or repair the existing one, the combo package is a great buy.
PORTER CABLE NAILED THIS ONE - THE GUN HAS NEVER JAMMED, IT IS VERY EASY TO CONTROL THE DEPTH OF THE NAIL EITHER FROM THE ADJUSTMENT ON THE GUN OR THE REGULATOR ON THE COMPRESSOR. THE COMPRESSOR ALWAYS HAS SUFFICIENT AIR. IF THIS BOTHERS YOU GET A LONGER AIR HOSE AND KEEP THE UNIT OUTSIDE. THIS COMPRESSOR SHOULD FIRE A FRAMING NAILER AS WELL, BUT IT WILL RUN MORE OFTEN. PORTER CABLE HAS DONE IT AGAIN.
This Combo will have your project nailed down !!! - It a great value and for those woodworkes who want a air nailer this combo should fit the bill. I sure there are those who may feel that an air nailer is just for those to lazy to nail by hand there not if you've ever made small boxes and tryed nailing them together you know it not and easy task. Porter-Cable has really out done shown thay are still the leader when it comes to great tools. Well done Porter-Cable.
Great Value - This was the first of what has become several Porter Cable items that I have purchased. I have been very happy with the performance of both the nailer and the compressor. The compressor has performed exceptionally well not only for the finish nailer, but I have also used it for roofing nailers, brad nailer, narrow crown stapler, paint sprayers, drywall texture sprayer, etc.
Phil Mescher from Ames, Iowa - I definately recommend this combo package to anyone wanting to start working with air nailers. Now I plan on buying a Porter Cable framing nailer.
Good buy not very portable with NO handle. - Both the compressor and the nailer work at least as well as advertised. The only place to grab is the plastic cover over the compressor pump, and that appears never to have been intended for use as a handle. Will contact Porter Cable and see if there is an accessory or aftermarked handle abailable.
Excellent Value and Quality - The compressor package truly makes it a great value. The compressor is very efficient, to the point that I was surprised it did not run more often. It is fairly quiet (as compressors go), and is light enough and is easy to carry and move around. Get Porter-Cable nails, which are of higher-quality and comparably priced.
Excellent performance and value! I am impressed! - Lightweight compressor delivers all the power and performance you need for this finish nailer. Compressor has convenient hand slot on top for ease of lifting and transporting. Great value combo from Porter-Cable that delivers. Compressor is made in USA, nailer is made in Taiwan.

This compressor by far exceeds what I expected it to do.
