Commercial Unit Heater Maintenance in Dutchess County

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 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.
