Commercial Start Up Services
Start It Right. Verify It Works. Document the Results.
New commercial HVAC equipment should never be placed into service with a simple flip of the disconnect. Proper startup requires a methodical inspection, operational testing, adjustment, and documentation process to confirm that the installed equipment is ready to perform safely and reliably.
Midwest Commissioning provides professional startup services for commercial mechanical HVAC equipment installed by mechanical contractors, general contractors, equipment representatives, and facility teams.
We work alongside the installing contractor to verify equipment operation, identify installation-related concerns, assist with system adjustments, and help deliver a system that is ready for occupancy and continued commissioning.
What our Startup Services Include
Startup procedures are tailored to the equipment, manufacturer requirements, project specifications, and actual jobsite conditions. Services may include:
-
Review of available equipment submittals, wiring diagrams, sequences, and manufacturer startup requirements
-
Visual inspection of installed equipment and accessible components
-
Verification of equipment model numbers, electrical characteristics, and installed configuration
-
Confirmation that electrical power, disconnects, breakers, controls, piping, ductwork, drains, and required utilities are connected
-
Inspection of filters, belts, bearings, dampers, fans, coils, compressors, heat exchangers, and accessible internal components
-
Verification of fan rotation, motor operation, voltage, amperage, and equipment safeties
-
Operational testing of cooling, heating, ventilation, economizer, reheat, dehumidification, and exhaust functions, as applicable
-
Refrigeration pressure and temperature checks where equipment design and site conditions permit
-
Verification of thermostat, controller, sensor, actuator, and BAS command response
-
Review of alarms, safeties, interlocks, and shutdown functions
-
Initial adjustment of operating settings within the manufacturer’s published requirements
-
Documentation of startup readings, observed deficiencies, and equipment operating status
