Commercial Heating & Furnace Repair Services
Commercial heating systems face heavy operational demands in retail stores, office buildings, warehouses, and multi-tenant facilities. Equipment ranges from packaged rooftop units (RTUs) and unit heaters to large-capacity split commercial gas furnaces. Heating downtime disrupts business operations, creates uncomfortable customer environments, and risks frozen fire sprinkler or water pipes.

Warning Signs & Common Symptoms
Recognizing early symptoms prevents mid-winter heating shutdowns and prevents further component damage:
- !Customer or employee complaints regarding cold work zones or erratic office temperatures
- !Building automation system (BAS) or smart commercial thermostat logging heating alarms
- !Squealing belts or loud vibrations heard on top floor ceilings beneath rooftop equipment
- !Sudden spikes in commercial facility gas or electric utility meters
Professional Service & Diagnostic Procedure
Qualified heating technicians utilize structured diagnostic sequences rather than guessing or replacing parts arbitrarily:
Rooftop Package & RTU Inspection
Inspect commercial economizer dampers, belt tension, and burner ignition packages on rooftop equipment.
Three-Phase Electrical Diagnostics
Verify voltage balance across all three phases (L1, L2, L3) and test motor starter overloads and contactors.
Commercial Gas Train Testing
Inspect dual redundant commercial gas valves, pilot assemblies, and safety interlocks for leak-tight operation.
Airflow & Static System Commissioning
Balance commercial supply volumes and test freeze-stat safeties to protect facility domestic water and fire systems.
What You Can Safely Check
- •Maintain an updated logbook of commercial equipment model, serial numbers, and filter dimensions
- •Schedule quarterly commercial filter and belt inspections to prevent unplanned business disruptions
