Preventive Maintenance FAQ’s

Each preventive maintenance contract is designed and engineered for your specific building or space. Standard options include but are not limited to the following options:

Spring Maintenance & Start Up

  • Clean all condenser coils with chemical cleaner and hoses
  • Clean evaporators-brush and wipe down
  • Clean condensate drain pans
  • Change air filters and fan belts on all rooftop units
  • Lube all fan bearings and motor bearings
  • Perform an operational checkout of cooling modes as per inspection sheet
  • Check electrical components

Mid-Summer Air Conditioning Check-Up

  • Change all air filters
  • Check operation of all HVAC Units
  • Check the exhaust fans
  • Change belts as necessary

Fall Maintenance & Start Up

  • Change all air filters
  • Inspect belts On all HVAC Units
  • Check operation of economizer on all HVAC units
  • Check operation heating sections on all HVAC units
  • Check electrical components

Mid-Winter Heating Check-Up

  • Change all air filters
  • Check belts on all HVAC units
  • Check operation of all HVAC Units.
  • Check HVAC exhaust fan.

The first step is to establish what needs to be included in the plan by taking an inventory of the equipment. Next, establish what, if any, the manufacturers recommendations are and then break the plan into a 12-month calendar. Meeting those requirements while keeping in mind year round and seasonal use concerns is something that we are cognizant of and will help you determine what should be performed and when.

Air Filters – Must be replaced on a routine basis, while maintaining good air quality and proper airflow.

Evaporator Coils – Although air filters catch particles, they are not 100% effective; therefore the evaporator coils must be cleaned periodically, keeping efficiency at its best.

Condenser Coils – This coil is subjected to the outdoors and requires yearly cleaning to keep its heat exchanging capabilities at its best. A dirty condenser coil can cause high running pressures, high amperage use on the compressor and ultimately equipment failure.

Belts – A bad belt is not one that is necessarily cracked, but a worn belt reduces its grabbing ability as well. Also belts must be periodically tightened and checked to get maximum airflow.

Lubrication – Many motors and bearings are considered “permanently sealed”, however many require routine lubrication preventing pre-mature bearing failure.

Condensate Drains – A plugged condensate drain means water problems. It causes condensate drain to overflow and water usually finds its way into the building.

Electrical System Components – Inspect all electrical contactors, switches, relays, controls, amp draws, and compressors. Document all findings.

General Observations – Overview of unit, tighten up loose components-caused by normal unit vibration, check control section.
