I wish I can give "0" if I can. My office has been with AC more than 1 year and I feel like I am in sauna in hot summer. Koll says it is too expensive and have kept saying we are working on it in long term. I also have a noise issue with my neighbor and Koll said we can't do anything with that. Stay away from Koll and recommend not to have business with them.
