I contacted La Salle because our facility needed work done on our AC units. I had met with 3 other companies prior to meeting with La Salle and the customer service La Salle offered was great! They explained to me what needed to be done and what options I had to get the problem fixed. Ernie is the person I was in most contact with and he's super helpful and quick to back to you with any questions that you have. Since then I've continued to use their services and have recommend them as well!
