What Is a Packaged Rooftop Unit (RTU)? | Heating & Cooling Explained for Condos & Commercial Spaces
Ever wondered what that big box is on the roof of your building?
In this video, Mark from Fountainhead Mechanical takes you on-site at a commercial retail center in Calgary to explain what a packaged rooftop unit (RTU) is, how it works, and why proper preventative maintenance is crucial.
We break down:
The difference between an RTU and a make-up air unit
What components live inside a packaged rooftop HVAC system
How hail guards protect condenser coils in Calgary’s harsh weather
What “fin combing” is and why airflow matters
Belt and blower inspections
The importance of cleaning condenser and evaporator coils
What “free cooling” and economizers actually do
These short, educational videos are part of our Condo Resource Library, which was built to help condo boards and property managers make confident, informed decisions about their buildings' mechanical systems.
