Equipment Maintenance

Commercial HVAC Maintenance

Consistently scheduled heating and cooling maintenance will keep your equipment performing properly. Commercial heating and cooling equipment often runs longer than residential equipment. Because the units operate longer, it is essential that filters are changed regularly. Your equipment could require maintenance between 1-12 times per year depending on the type of filter and the usage of the equipment. Dirty equipment and filters are a leading cause of commercial heating and cooling problems.

A typical planned commercial HVAC maintenance for a rooftop unit covers:

  • Checking with building manager for any problems
  • Verification of proper unit operation
  • Filter replacement or cleaning (depending on filter type)
  • Equipment cleaning
  • Lubrication (if needed and required)
  • Refrigerant levels check (in cooling season)
  • Belt tension adjustment
  • Belt inspection
  • Communicate findings and any recommended repairs
