Rooftop packaged units face severe thermal stress, environmental contamination, and electrical wear. Our team resolves critical commercial failures fast.
Diagnostics for tripped high/low pressure switches, failed contactors, thermal overload trips, low refrigerant charges, and burnt-out commercial compressors.
Testing and replacement for cracked gas heat exchangers, faulty hot surface igniters, clogged burners, pressure switch errors, and gas valve failures.
Immediate repair for snapped V-belts, misaligned pulleys, failed blower motors, worn bearings, and unbalanced indoor supply fan assemblies.
Calibration and repair for seized outdoor dampers, faulty enthalpy sensors, and broken actuator motors forcing improper outside air intake.
We approach every commercial repair call with methodical engineering protocols to identify root causes and prevent repeat callbacks.
We inspect main disconnects, safety interlocks, control voltage transformers, and thermostat wiring to trace power interruptions.
Technicians connect digital manifolds to measure superheat, subcooling, compressor amp draws, and refrigerant pressure differentials.
We verify static air pressure across coils, inspect heat exchangers for micro-fractures, and test gas manifold pressures for TSSA compliance.
You receive an itemized diagnostic report with unit photos, clear component cost breakdowns, and recommended preventative action.

Common technical inquiries property managers and building operators ask about rooftop HVAC repairs.
Commercial RTU repair costs depend on the specific component and labor required. Standard diagnostic inspections and minor electrical/belt repairs generally start between $150 and $350. Major mechanical overhauls—such as replacing a 10-ton commercial compressor, blower motor, or gas heat exchanger—range higher. We provide transparent, itemized estimates before proceeding with any repair.
Warm air coming from supply vents usually indicates one of four common issues: a frozen evaporator coil caused by clogged air filters or snapped blower belts, low refrigerant levels from micro-leaks, a tripped high/low pressure lockout switch, or a failed compressor contactor/capacitor preventing the compressor from engaging.
Signs of a cracked heat exchanger include burner flame distortion or fluttering when the supply fan turns on, soot accumulation around burner ports, frequent high-limit trips, or carbon monoxide alarms in tenant spaces. Under Ontario TSSA safety regulations, a cracked heat exchanger requires immediate unit lockout until the heat exchanger assembly or complete unit is replaced.
Commercial rooftop units should be professionally inspected at least quarterly (4 times per year). High-demand environments such as commercial kitchens, manufacturing facilities, or 24/7 retail plazas often require monthly filter and belt inspections to prevent unexpected downtime and maintain energy efficiency.
As an industry guideline, if a commercial RTU is over 12 to 15 years old and the estimated repair cost exceeds 50% of a new unit replacement—or if it operates on phased-out R-22 refrigerant—replacing the unit is usually more economical. Modern high-efficiency units significantly lower ongoing energy bills and eliminate frequent emergency service calls.
