As a retired collision repair specialist I am very hard person to impress when it comes mechanical service on my 2004 Toyota Truck. Four months ago i took my truck to this shop with hot AC. Two good mechanical shops had tried and failed to diagnose problem correctly despite repeat visits. Gerald and his crew persevered and diagnosed the problem correctly the first time, repaired it with high quality parts and returned to me ice cold and good as when bought truck. I waited four months to give review. Still perfect. I have had several occasions since to have other repairs. They are the most meticulous techs in area.They check everything. They keep you informed of status of repairs and have excellent management and technicians to do the work. They do not recommend services/repairs that are not needed. I travel about 1/2 hour to get to them. Well worth it.
