For Standby Generators

• Visual Inspection
• Check intake and exhaust for obstructions
• Check fault codes
• Check battery and charger
• Check oil level/condition and for leakage
• Check coolant level and condition (where applicable)
• Replace air filter
• Replace spark plugs
• Valve lash adjustment if required
• Manual start
• Verify the voltage and frequency output
• Adjust fuel regulator, check the venting
• Check and adjust engine speed
• Change oil using synthetic oil and replace the oil filter
• Transfer to generator power with a simulated power outage
• Transfer back to utility power

For Ductless Heating and Cooling Systems

• Check wiring and tighten connections at the outdoor unit
• Check voltage supply and amperage draw from the outdoor unit
• Check connections at the outdoor unit for leaks/damage
• Inspect for refrigerant leaks
• Inspect and clean outdoor condenser coil and fan
• Straighten any damaged fins
• Inspect and repair exposed pipe insulation
• Wipe down the outdoor unit
• Inspect and change batteries in remote
• Inspect and clean filters
• Remove condensate pan and inspect/clean
• Inspect and clean blower wheel
• Clean, inspect and straighten fins on evaporator assembly
• Blow out condensate line and verify drainage
• Add algicide tablet to the condensate pan
• Clean and inspect louvers and cabinet
• Verify proper operation after re-assembly

What you can do year-round to make sure your generator runs properly:

• Keep bushes and grasses trimmed away from generators
• Be sure landscapers do not put mulch right up against the generator so as not to get mulch sucked into air intakes and block air flow
• In the fall, be sure that leaves are cleared away from the generator to avoid possibility of fire
• In the winter, be sure snow is not allowed to build up to a height that would cover the generator
• Never build any enclosures or covers over or around the generator that will affect airflow and cause overheating in summertime or impede the ability to service the generator
