We contacted Alisea to help us assess the health risk of our air handling systems and to define an inspection and maintenance plan in order to keep them in conditions that do not cause dangers to our workers. The work was carried out with professionalism and accuracy. What has struck us favorably is the professionalism and the willingness to grasp our specific needs to make improvements to the work underway. We have found in Alisea a qualified partner with whom to safely manage our air handling systems and we would certainly recommend it.
