I called McCain's about my AC in my 02 Tahoe, which had been squeeking and on a couple of occasions been blowing hot air. Eric (the service manager) told me that it sounded like my Compressor was going out and it would probably cost around $1000. I took my Tahoe in the next week expecting to be out $1000. Midday Eric called me and told me my pressures were off and he didn't see any signs that I needed a new compressor. He could have gone ahead and put the new compressor in, but he didn't. He told me the truth, which is something that a lot of Auto Shops don't do these days. I give McCain's my highest reccomendation!
