📞 Call (980) 246-8500J&A Welding and Maintenance LLC provides scheduled preventive maintenance for commercial rooftop HVAC units at restaurants, retail spaces and commercial buildings. Regular inspections and upkeep help you catch small problems before they turn into downtime, and help your equipment run efficiently for longer.
Rooftop unit inspection, system checks and seasonal tune-ups.
Filter replacement and coil cleaning to help keep air moving and the unit running efficiently.
Belt tension and blower checks, so a loose belt does not leave your unit without airflow.
Scheduled visits for your location. Ask us about a maintenance plan.
The client reported that their rooftop unit wasn't working. When we inspected it, the blower wasn't running because the belt was too loose. We adjusted the belt tension, and we found the air filters heavily clogged, so we replaced them. Small things like a loose belt or dirty filters can stop a unit from moving air, and regular preventive maintenance helps catch them early.
