Commercial Maintenance Plans

 
  We recommend maintenance of all your heating and cooling equipment to ensure greater reliability, greater energy savings, and peace of mind.

Andgar can develop a Preventative Maintenance Plan to fit the specific needs of your building.

Gas, Propane, or Electric Furnace maintenance includes:

•Testing of safety controls and shut-offs
•Inspection and cleaning of the automatic controls including control boards, gas valves, inducer motors and wheels
•Check of blower, motor and belts for wear, tension and alignment
•Removal and cleaning of burners and flue pipe
•Visual inspection of heat exchanger
•Inspection of all wiring for loose connections and damaged insulation
•Testing of supply voltage and amperage draw
•Cleaning and flushing of condensate system
•Check for proper air flow and distribution temperature
•Lubrication as needed
 

Heat Pump or Air Conditioner maintenance includes:

•Testing of safety controls and shut-offs
•Check of defrost cycle and reversing valve
•Check for proper air flow for maximum efficiency
•Check of blower, motor and belts for wear, tension and alignment
•Check for refrigerant and oil leaks
•Testing of electrical controls for proper operation
•Check of refrigerant pressures and temperatures during normal run cycle for maximum efficiency
•Replacement or clean air filter
•Cleaning and flushing of condensate system
•Lubrication as needed
