“The work of A. de Jong Installatietechniek involves mechanical installations: heating, cooling and air conditioning. They handle the technical maintenance; we handle the management ourselves. Our relationship with De Jong started a long time ago. What I really like is the fact that those who work for De Jong stay with the company for a long time: I know who I am dealing with. I don’t have to explain everytime, because the knowledge is there. When I have new plans, I just have to present them. They then collaborate with me and find solid solutions. They are equal partners; to put it in other words, they get it and they do it. They meet their commitments; I do not have to check up on them and they think ahead. They have a good understanding of my company and they know what is important for us.”

"We awarded A. de Jong Installatietechniek the contract to renovate the boiler room, including equipment, and provide related services. They did an excellent job. What I found most impressive is that they did more than they were contracted to do. They fixed a defect for which the supplier was actually responsible and solved a technical problem, even though we have no maintenance contract with De Jong. You rarely find such commitment and service anymore. As a result, I think we will do more business with De Jong in the future. They are close by, can monitor our installations and provide offsite support for our own technical department. Their mechanics have all the required know-how and their system controllers are not easily satisfied. It is exactly what I am looking for."
