Air handling units are the heart of a building’s ventilation and climate control. They move, filter, heat and cool the air your occupants breathe every day.
SNAP Mechanical installs, maintains and services AHUs for commercial, institutional and industrial facilities across the GTA, York, Durham and Peel, so your building stays comfortable, efficient and compliant.
A neglected unit can quietly drive up energy bills, reduce air quality and fail at the worst possible time. With the right installation and a reliable maintenance plan, your AHU can deliver dependable performance for years.

Frequently Asked Questions
How often should an air handling unit be serviced?
Most commercial AHUs benefit from scheduled maintenance several times a year, depending on the unit, how heavily it’s used and the air quality conditions in your building. Filters in particular may need more frequent attention. We’ll recommend a schedule that suits your equipment and operations.
What are the signs that my AHU needs attention?
Common warning signs include uneven temperatures, weak airflow, unusual noises, rising energy bills, odours and filters that clog quickly. Any of these can point to a developing problem. Early service usually costs far less than waiting for a failure, and it helps protect indoor air quality.
Can you replace an AHU without shutting down my building?
In many cases, yes. We can plan the work in phases or schedule key steps after hours to reduce disruption. Crane access, shutdown windows and temporary measures all depend on your building, so we’ll go over scheduling and logistics with you during the quoting stage.
