Mechanical contractor and business owner and I have been dealing with Johnstone Owasso for several years and can say they’ve always been “Johnny on the spot” for me. Well stocked for parts and equipment and willing to go out on the hunt if I’m searching for an obscure part. Counter guys are knowledgeable and helpful in most every situation.
