Review how your building schedules HVAC before you assume you need new equipment.
Runtime and maintenance affect energy use, but unoccupied areas may still need ventilation or dehumidification. Review operating schedules with your facilities team and mechanical contractor.
Compare occupied schedules to when equipment actually runs.
When schedules leave rooftop units running during unoccupied hours without a building need, runtime can increase energy use. Adjust schedules only where humidity, ventilation, and freeze protection requirements for your building are still satisfied.
Plan coil and filter maintenance on your equipment.
Dirty filters and coils can increase runtime. Maintenance visits address these items on equipment your program covers.
Compare usage records with changes in your building.
Review electricity use alongside weather, occupancy, operating hours, and service records. A higher bill alone does not identify a failed component or prove that replacement will save money. Record schedule changes and maintenance work so your facilities team can compare operation before and after the change.

Read these answers before you request service.
Will turning off HVAC at night always save money?
Schedules should match actual occupancy and ventilation needs. Review operating hours against building use before changing setpoints.
Can dirty coils increase operating cost?
Blocked coils can raise energy use and stress compressors. Maintenance that includes coil cleaning is scoped in your agreement.
Should we change schedules without facilities review?
Coordinate with your operations team so ventilation, humidity, and tenant leases are considered.
When should we request a technician instead of adjusting schedules?
When comfort problems persist after schedule review, request diagnosis on the equipment serving affected areas.
