Commercial HVAC Rooftop Unit Installation

Design, Built & Installation

Every Rooftop Installation is Unique Not every rooftop unit replacement is a simple swap. Sometimes, the dimensions of the new unit don’t match the existing rooftop opening. In these cases, Airtronic Heating & Cooling provides custom solutions — such as professionally fabricated curb adapters — to ensure a proper fit and optimal system performance. Our experienced team carefully assesses each project to determine exactly what’s needed for a smooth, efficient installation.

Before and After: Rooftop HVAC Upgrade

We replaced an old side-discharge rooftop unit causing energy loss with a new energy-efficient system. Using a custom insulated curb adapter, we redesigned it to bottom discharge for better airflow and maximum efficiency.

★★★★★ 5/5

These guys are next level professional. They checked everything including CO detection, to the point of exhaustion, to make sure the furnace was safe for my family. Really nice guy. Really smart. I’d recommend them to anyone.

Nice efficient , with no hidden charges

Look no further for ANY assistance with your HVAC system, Saeed and his team are incredible! They have saved us on multiple occasions when Reliance or Enbridge have been unavailable. We had a gas leak in our patio due to a corroded pipe and the city had to turn off our gas in the middle of winter. I called Saeed and even though it was late in the night, he made himself available to come and help. Within an hour he did all the repairs and was able to restore heat and safety to my home. Top marks on everything! Great customer service, incredible quality of work and fantastic responsiveness. Cannot recommend these guys enough! A huge thank you to Saeed and the Airtronic Team!
