Commercial Unit Heater Maintenance in Fishkill, NY
Commercial unit heaters are critical assets in warehouses, shops, and industrial spaces across Fishkill, and they need regular maintenance to run efficiently through cold months. We perform seasonal inspections, clean heating elements, check gas connections for leaks, and test thermostat accuracy before winter arrives. Proper maintenance prevents unexpected downtime, extends equipment lifespan by years, and keeps your facility warm without emergency service calls.
Why Choose All Systems for Commercial Unit Heater Maintenance in Fishkill
Commercial unit heaters operate continuously in high-demand environments, moving large volumes of heated air through ductwork or directly into open spaces. Our maintenance process begins with a detailed inspection of the heating element condition, burner assembly, and gas valve operation. We clean dust and debris from the heat exchanger fins, measure gas pressure at the outlet, verify thermostat calibration, and test all safety controls including the limit switch that prevents overheating. We inspect gas supply lines for corrosion or leaks using electronic detection, check electrical connections and capacitors, and run the unit through a full heating cycle under load. Finally, we document all findings, provide written recommendations for any repairs needed, and schedule follow-up service if components show wear. / Regular maintenance catches failures before they happen. A unit heater that hasn't been serviced in years can lose 20 to 30 percent of its heating output due to clogged fins and a dirty burner. When a heater fails mid-winter on a warehouse floor, you lose production, product quality suffers, and emergency service rates apply. Our clients in Dutchess County keep their units on preventive maintenance contracts and never face that scenario. / Beyond heating performance, maintenance protects your safety investment. Unit heaters with faulty limit switches or blocked combustion air intake can overheat and create fire hazards. Gas leaks from corroded supply lines go undetected without professional pressure testing. Thermostats that drift out of calibration waste fuel or leave workers in cold conditions. Our maintenance visits catch all of these issues and bring your system back into code compliance.

Seasonal Burner Cleaning and Inspection
We disassemble the burner assembly, clean combustion residue and carbon buildup from the igniter and gas ports, inspect the electrodes for wear, and test ignition reliability under full load. A clean burner fires efficiently and maintains stable combustion throughout the heating season.

Heat Exchanger and Fin Cleaning
Dust and lint accumulation on the heat exchanger fins reduce air velocity and heat transfer efficiency significantly. We clean fins using compressed air and specialized brushes to restore surface area, improving heat output and reducing runtime needed to reach setpoint in Fishkill facilities.

Gas Pressure Testing and Valve Calibration
We measure gas pressure at the unit outlet against manufacturer specs, test the gas valve for proper opening and closing, and check for leaks at all connection points using electronic gas detection. Proper pressure ensures efficient combustion and prevents gas odor or safety issues.
