Work was good. Completed in a timely manner and when told it would be finished. Only issue I have is some of the pricing. Call it lack of communication or high pricing, but $70 to replace a $15-20 air filter was too much. With over $1200 in work, don't need to stick it when replacing a filter takes me 5 minutes. I will still continue use Wilhelm, for its the closest and compared to the other competitors, Wilhelm is by far the least of all the evils.
