Research Air Flo, Inc. has been our go to TAB company for several years. Their technicians are well trained on DDC and the older pneumatics controls systems and communicate with us as they start a project and when they leave it with updates of any deficiencies that need to be addressed. This is important as it allows us to make timely repairs before the tenants move in. As a property management company, it is important for us to have a good relationship with the TAB contractor as they are the final eyes set on the HVAC system for a project. Joel, from their management, has been very good to deal with and we feel that they willingly partner with us to provide the best environment possible for our tenants.
