Common Trane Rooftop Unit Problems
Trane rooftop units are a favourite in office parks and multi-tenant buildings across Markham, North York and Mississauga, often tied into a building automation system. The calls we see most are Trane Voyager units short cycling, Trane Precedent units throwing ReliaTel controls faults, and RTUs that are not talking properly to the BAS.
Controls problems are where guesswork gets expensive. A ReliaTel module can look failed when the real issue is a sensor, a wiring fault or a bad signal from the BAS. We read the fault history with the right tools before replacing anything.
Trane Models We Sell and Service
Trane Precedent
A common packaged unit in light commercial sizes, used on plazas and smaller offices. Typical service: controls, economizers, compressors and fan motors.
Trane Voyager
Trane's larger packaged line, common on office buildings and big-box retail. Voyager units often run multi-stage compressors and full economizers, and short cycling is usually a controls or charge issue.
Trane CenTraVac chillers
Centrifugal chillers in many GTA office towers. Our CRE-ticketed crew handles retubes, startups and layups. See commercial chiller service.
BAS Integration for Trane RTUs
Many Trane units serve buildings with a BAS. We integrate them over BACnet with Trane, Johnson Controls Metasys, Honeywell, Siemens Desigo and Delta platforms, verify every point, and set alarms so problems reach the property team before tenants complain. This matters most for Markham office parks with server rooms that cannot lose cooling; see our Markham page.
