Rooftop Unit Installation & Replacement Toronto

Roof, Power and Controls

A New RTU Is Only as Good as the Curb, Wiring and Ductwork Under It

Many rooftop unit problems after a replacement come from what the unit connects to, not from the unit itself. A curb that doesn’t match the new footprint leaks, an undersized electrical supply trips breakers, and a poor ductwork connection loses conditioned air into the ceiling space.

Before install day, our technician checks the existing curb, the electrical service and disconnect, the thermostat or control panel, and the supply and return openings. Where the new unit has a different footprint, we fit a curb adapter so it sits weathertight on the existing opening.

These are the issues we look for on existing rooftop units:

• Short-cycling: an oversized unit that reaches its set point too fast and wears out its compressor.
• Dirty coils and filters: blocked airflow that raises energy bills and cuts cooling capacity.
• Rusted cabinets and drain pans: weather exposure that lets water into the curb and the ceiling below.
• Failed economizers: dampers stuck open or closed that waste energy or starve the space of outdoor air.
• Worn compressors and fan motors: noise, tripped overloads and falling output on older units.
• Cracked heat exchangers: a fault in the gas heat section that usually means replacing the unit.

Brands we work with include KeepRite and Copeland, and our technicians service both the rooftop units and the refrigeration equipment on your roof. Our clients include property managers, retail plazas, restaurants, office buildings and light industrial sites.

What Sets the Price of a Rooftop Unit Installation

No two roofs or buildings are the same, so we don’t quote rooftop unit installation over the phone. The price depends on the unit’s capacity and efficiency, the work on the roof and the connections inside the building. You get a firm written quote after our site assessment, before any work begins.

What affects the cost:

• Unit size, configuration and efficiency rating
• Crane lift, roof access and any street occupation permit
• Curb adapters, electrical upgrades and ductwork connections
• Removal of the existing unit and after-hours scheduling

If the lift needs a mobile crane or boom truck on a City of Toronto road or sidewalk, the City requires a Street Occupation Permit, so allow time for it in the schedule.
