With over 30 years’ experience in the HVAC industry, I have found Research Air Flo to be one of the best Air/Water balancing contractors to work with in North/South Carolina. I have dealt with many T/B contractors over the years and RAF has improved my opinion of the T/B subcontractors. RAF has raised the standards of T/B contractors and has made other T/B contractors perform better. We have full confidence in their staff, and their abilities to balance air/water systems to meet design criteria. It is comforting to know they will work with our staff to find and help resolve any issues which may arise on any size project.
