My air conditioning had been going on and off for the last 2 weeks couldn't figure out why I checked all the all the breakers all the fuses check the AC condenser check the everything the clutches engaging everything was fine and then you could drive it for 5 minutes or you could drive it for an hour and all of a sudden the AC would blow nice and hard so I stopped into Speedy Lube but their machine was down they said hey go over here to Duncan's they're a good shop and I went over there and met Greg. I explained the situation. they couldn't look at it that day cuz it was close to the end of the day so I brought it back the next morning and lo and behold it was a hidden relay that apparently when it got hot it would engage so that's why it tested good when i checked it. Greg and the staff were great. They had it fixed by mid day the following day. Voila, now it blows like the wind. Price was reasonable. Facility was neat clean and tidy. Highy recommend this shop.
