Mastercraft Air Compressors

Mastercraft air compressors are the house brand of a nation-wide, Canadian company that markets a broad range of homeowner and light industrial tools and equipment, all under the Mastercraft brand.

The basic brand - Mastercraft - is their name for their household type tools and equipment. If you are seeking equipment that's more industrially oriented, you would look for their Mastercraft Maximum line.

You can acquire Mastercraft air compressors at the Canadian Tire stores throughout Canada, and online in Canada and in the U.S.A. as well, compressors that I suspect were "job lots" purchased at a discount and sold in other outlets.

Canadian Tire also sells a few models of their MotoMaster air compressors. These used to be 12 VDC compressors designed for airing-up tires, and were, essentially, a consumable. Use it until it breaks then toss it out. More recently they have started offering MotoMaster compressors in larger sizes, with 120 VAC motors and larger pumps.

Like many big box stores Canadian Tire does not manufacture their compressors themselves, but has companies around the world manufacture Mastercraft and Motomaster air compressors private labelled for them from a variety of sources, though typically Asian.

Canadian Tire big box style stores offer little, if anything, in after market compressor parts for the compressors they sell. If you have a problem with your Mastercraft air compressor and you have owned it long enough that it is out of warranty, good luck getting parts for it though this forum may help.

Mastercraft air compressor

You can try contacting their customer service desk at this URL: . Odds are good though that they will not be able to help in getting compressor parts.

You could also try asking a store clerk where you purchased your Mastercraft compressor if they send compressors out for rebuild under warranty and then contact that company for parts. I suspect though that when a low-cost compressor comes back under warranty, they simply give you a new one and junk the returned compressor rather than trying to fix them.

You can use this forum page for folks that own Mastercraft air compressors, regardless of origin, and need some help with them.

Mastercraft air compressors are inexpensive

By and large Mastercraft air compressors are cheap. On sale, you can often purchase a new one for under $100. With a retail price at that level, there is nothing in that price that allows handling costs for shipping compressors out for repair, or stocking parts which is likely why the stores don't even try to have compressor parts.

Further, from one year to the next it might be a whole different company making the Mastercraft air compressors that year. Compressor shapes, sizes and capacities seem to change often, as Canadian Tire adapts compressors and prices to meet the changing needs of their market.

When you have a problem with your Mastercraft air compressor then, this forum is a good place to try to find information and parts sources. This forum will provide troubleshooting tips for Mastercraft air compressors and complimentary download of manuals that other users have been kind enough to provide.
