Rooftop Unit Replacement in Toronto & GTA

Rooftop Unit Replacement and New RTU Installation

A rooftop unit has one job: keep your space comfortable without drama. When an RTU is near end-of-life or can’t keep up with your building load, replacement is usually the fastest way to restore stable heating and cooling. HVAC Bureau handles RTU changeouts and new rooftop installs with a clear scope, controlled execution, and a clean handover your team can keep on file.

What a new RTU improves

• More stable heating and cooling for occupied spaces
• Better efficiency compared to aging rooftop equipment
• More predictable performance during peak hot and cold days
• Cleaner, more organized rooftop equipment setup

When replacement makes sense

• The unit is near end-of-life
• Comfort complaints keep coming in
• The system runs constantly but can’t hold temperature
• Energy costs are climbing season after season
• You need a planned changeout that reduces operational risk

How Your RTU Project Works

Rooftop work is all about planning: access, safety, scheduling, and commissioning. The goal is to complete the changeout cleanly and confirm performance before we leave the roof.

1) Site review and access planning

We review:

• Existing RTU model, capacity, and condition
• Roof access and placement constraints
• Curb, duct connections, and transitions
• Electrical and gas connections tied to the unit
• Scheduling limits and downtime windows

2) Clear scope and replacement plan

You receive a straightforward proposal that outlines:

• What’s included and what’s not
• Equipment options that fit your building needs
• Timeline and install-day plan
• What we need from your site team for access and coordination

3) Replacement and commissioning

On install day we focus on controlled execution:

• Removal and disposal of old rooftop equipment
• New unit set and required connections
• Startup, testing, and commissioning checks
• Verification that the unit operates as intended

4) Handover for your records

Before closeout, you get:

• Walkthrough of the completed work
• Key equipment details you can keep on file
• Commissioning notes and a clean close-out

What’s Included and What Affects Price

RTU pricing depends on equipment capacity, rooftop access, and how much needs to be updated around the curb and connections. The right approach is a clear scope up front and a clean install that’s verified before handover.

Typical scope includes

• Removal and disposal of old RTU equipment
• New rooftop unit installation and required connections
• Curb and connection scope as approved
• Startup, testing, and commissioning checks
• Jobsite protection and cleanup

Standards and safety on the roof

Rooftop work has to be planned and executed safely. A proper RTU install is not just placement — it’s correct connections, correct setup, and verified operation.

What affects price and timeline

• RTU capacity and efficiency tier
• Roof access and rigging requirements
• Existing curb condition and required transitions
• Duct connection scope and modifications
• Electrical and gas scope tied to the changeout
• Permit/inspection requirements when applicable
• Scheduling constraints and downtime windows
