Roof Top Units

Periodic maintenance, minor or major repair, or replacement, roof top units are our specialty.

Roof top units or RTUs are in all shapes and sizes.  Capacities range from 1-1/2-tons to over 25-tons.  Power sources range from 230Volt single phase to 460Volt three phase.  Refrigerant bases are R22 to 410A.  And heat sources can be electric, propane, or gas.  The technicians at Douglas Mechanical, Inc. are trained and experienced to service and repair all types, makes, and models.

From simple filter changes to changing and adjusting belts and greasing bearings to chemically cleaning coils, let us help with preventive maintenance.

When it comes to replacement, we have options to possibly utilize your existing curb or choose the unit best for your application and employ a curb adapter.  Keep your building pressurized with motorized outside air dampers, protect your exterior coils with hail guards, and protect your ductwork and space from water damage with condensate float switches.
