Best Air Compressors

While air compressors might not be at the top of every DIYers’ must-have list, these tools are actually very useful for a wide range of purposes. The right air compressor can do everything from inflating your car tires and pool floats to putting the “power” in your power washer to running pneumatic tools such as paint sprayers and air-driven nail guns.

Of course, it’s not just a construction tool. Automotive, woodworking, aviation, marine, and many others use a compressor to power air tools. When we got our team together to decide on the best air compressor, we sparked a fierce debate concerning brands, styles, prices, and much more.

There are portable air compressors and models intended to remain stationary—generally, portable models are best for homeowners or DIYers, while stationary models are better suited to professional purposes. Tank size is another important consideration, as the larger the tank, the more power the tool can provide. Still, for most DIY projects, a 4-to-6-gallon tank is sufficient.

Benefits of Air Compressors for Home Garage

  • Powerful. Using an air compressor to power pneumatic tools like staplers, brad nailers, paint sprayers, and other tools greatly increases your efficiency and cuts down on the time it takes to complete a job.
  • Versatile. An air compressor in your home garage can do a wide variety of tasks. Whether you’re an artist, hobbyist, DIY enthusiast, or automotive guru, you likely have a power tool or piece of equipment that could run better with the aid of an air compressor. You can also use it to quickly inflate tires, paddleboards, basketballs, and plenty of other outdoor gear in minutes.
  • Portable. Most air compressors for home garages are sized to be space-saving and highly portable so that you can easily move them from one area of your garage to another, or even take them to a job site or friend’s workshop for use in different locations.
  • Low-maintenance. Most of today’s air compressors that are sized and suited for home garage uses are low-maintenance and economical, saving you time and money over owning a larger capacity air compressor.

How We Selected

To find the best compact compressors, I evaluated available models in terms of portability, power, professional features, and my experience testing them (for the ones I’ve gotten my hands on). Two important criteria were that each one here has an oil-free pump and produces between 90 and 165 PSI of air pressure. (Most air tools require 40 to 90 PSI.) And compressors are rated by the size of their storage tank, so I’ve chosen the best on a range—five different sizes from one to six gallons.

Another reason these models earn the title of best is because each is engineered to withstand the rough and rigorous demands of professional contractors, but they’re all priced well within the budget of most DIYers. Plus, despite their small size, they sacrifice very little when compared to a large, traditional model. In fact, since getting my compact compressor three years ago, I haven’t moved my 30-gallon one from its cozy corner in the garage.

You should never buy a product before being satisfied that all of your questions have been answered. Take a look at these frequently asked questions about air compressors and their answers below.

How does an air compressor work?

An air compressor works by converting power into potential energy in the form of compressed air, using an electric motor or gas engine. Air is forced into the tank where the pressure begins to build. Once the pressure within the tank reaches the tank’s upper safety limits, it shuts off until the air is released or used with a pneumatic tool.

When used, the air compressor provides a burst or stream of powerful, compressed air to fire nails from a nail gun, spray paint from a sprayer, or loosen automotive nuts with an air ratchet. The tank will then begin repressurizing until it returns to its upper-pressure limits. To shut down the air compressor, simply turn it off and release the compressed air with the ASME safety valve. When the PSI has been lowered to 10, release the drain valve at the bottom of the unit to allow any accumulated moisture to drain from inside the tank.

Are air compressor hoses universal?

Yes, to a degree. Whilst commercial air hoses may be a different size, in the main domestic air hoses are universal and can be used with any air compressor. There may be a need for different adapters and couplers depending on your compressor.

My air compressor will not start!

There are several things that could be causing this, the first things to check for would be, is the compressor plugged into a socket directly and not an extension lead, is the fuse good, does the compressor have oil in it. After this, it is worth consulting the manual for more troubleshooting steps.

What is the best air compressor for home use?

The best compressor for home use totally depends on what you’ll be using the compressor for. If you’ll just be airing up tires occasionally, a small air compressor that runs off a car’s accessory outlet will likely serve you best. If you want to run power tools with it, you’ll need to look at bigger, more powerful models with air tanks.
