What is Preventive Maintenance?

Preventive Maintenance is the single most important activity needed to protect the investment in your mechanical assets. The advantages of performing regular maintenance on your HVAC system are unmistakable. Preventive maintenance ensures the efficiency of your mechanical systems, reduces energy costs, and maximizes the life of your equipment.

According to The American Society of Heating, Refrigerating and Air-Conditioning Engineer (ASHREA), with proper maintenance, the average lifespan of a commercial HVAC system is fifteen (15) years. Without the proper maintenance, even the best HVAC systems will fail before reaching their life expectancy.

Preventive maintenance includes, but not limited to:

  • Replace filters on cooling and heating equipment
  • Check condition of belts and pulleys and replace as needed
  • Clean condenser and evaporator coils
  • Check refrigerant charge and inspect for leaks if charge is low
  • Clear drain lines and pans
  • Check electrical connections
  • Check operation of fan and blower motor and adjust if needed
  • Inspect ignition and burner assembly
  • Inspect heat exchanger
  • Lubricate motors, bearings and other moving parts
  • Check operation of thermostats and other controls
  • Check for adequate air flow
  • And any tasking specific to the manufacturer

If no inspections or repairs are made when necessary, the life expectancy of a system drastically decreases.
