Rooftop HVAC and ventilation equipment works year-round in Toronto's variable climate — and it needs regular inspection and maintenance to keep operating safely and efficiently. Universal Duct Cleaning provides professional rooftop unit service and maintenance for commercial and residential properties across Toronto and the GTA, covering rooftop packaged units, exhaust fans, ventilation components, and associated ductwork.
Rooftop HVAC equipment is often out of sight and, consequently, out of mind — until performance drops or a leak or failure creates a costly problem. Exposure to Toronto’s freeze-thaw cycles, UV, wind, and debris makes regular maintenance essential for rooftop units. Universal Duct Cleaning provides rooftop equipment inspections and servicing for commercial and residential properties across the GTA, covering filters, coils, exhaust fans, ventilation hoods, drain pans, seals, and flashing — keeping your rooftop systems running efficiently and your building envelope protected.
Worn flashing, deteriorated curb seals, or improperly sealed penetrations around rooftop units can allow water into the building — often going unnoticed until interior damage has occurred.
Rattling, vibrating, or grinding sounds from rooftop equipment can indicate loose components, debris accumulation, or wear that needs to be caught before it becomes a failure.
Dirty coils, clogged filters, and restricted airflow in rooftop units all reduce their ability to deliver rated heating or cooling capacity to the building below.
Leaves, organic material, and airborne debris build up around and inside rooftop units, restricting airflow and accelerating corrosion and wear on the equipment.
Commercial rooftop units should be inspected and serviced at minimum twice per year — before heating season and before cooling season — to stay ahead of issues.
Equipment operating with dirty coils, restricted filters, or accumulation issues has to work harder to deliver the same output, driving up energy consumption and operating costs.
We inspect all rooftop HVAC units, exhaust fans, and ventilation components for condition, performance, and any visible maintenance concerns.
Filters in rooftop units are inspected and replaced as needed to restore proper airflow and protect indoor air quality.
Evaporator and condenser coils are inspected and cleaned to maintain heat transfer efficiency and prevent biological growth on coil surfaces.
Leaves, dirt, organic material, and biological growth are cleared from around and within units to ensure unrestricted airflow and reduce corrosion risk.
All roof penetrations, equipment curbs, flashing, and seals are inspected for integrity to identify any water infiltration risk before it causes interior damage.
Rooftop exhaust fans and ventilation hoods are inspected, cleaned, and tested to confirm proper operation and unobstructed airflow.
We inspect all rooftop HVAC units, exhaust fans, and ventilation components, documenting their current condition and identifying any immediate concerns.
Filters are replaced and coils are cleaned to restore the unit's operating efficiency and heat transfer performance.
Units and the surrounding roof surface are cleared of debris, organic material, and any growth that could restrict airflow or accelerate equipment wear.
All equipment curbs, roof penetrations, and associated flashing are checked for integrity to identify any water infiltration risk.
Equipment is tested after servicing and a summary report is provided documenting all work completed, observations made, and any recommended follow-up items.
Commercial rooftop units should be serviced at minimum twice per year — typically in spring before cooling season and in fall before heating season. Higher-use systems or buildings in environments with elevated debris may benefit from more frequent attention.
We service rooftop packaged HVAC units, exhaust fans, make-up air units, ventilation hoods, rooftop air handling units, and associated ductwork for commercial, industrial, and residential buildings.
Yes. We service residential rooftop equipment including attic ventilation fans, rooftop exhaust vents, and associated ductwork, in addition to larger commercial rooftop systems.
Yes. Clean filters, clean coils, and unobstructed airflow allow rooftop units to operate at rated efficiency, reducing energy consumption, lowering utility costs, and extending the service life of the equipment.
Our crew follows safe work practices for all rooftop access, including appropriate personal protective equipment and fall protection procedures in compliance with Ontario occupational health and safety requirements.
