Commercial HVAC and Rooftop Unit Installation in Toronto, Mississauga, Vaughan and the GTA
Commercial HVAC refers to heating, ventilation, and air conditioning systems that operate on a larger scale than residential systems. These systems regulate temperature and ventilation for various commercial buildings, including restaurants, hospitals, offices, and warehouses. Depending on the application, commercial HVAC systems in Toronto may use different heating and cooling methods, such as fuel combustion or electricity. They also vary in installation types, with one of the most common being rooftop installation (Toronto and the GTA area).
At ACfurnaceGTA Corp, we specialize in a wide range of commercial HVAC solutions for businesses in Toronto, Mississauga, Vaughan and the whole GTA, including boilers, high-input water heaters, garage unit heaters, ductless air conditioning units, commercial heat pumps, and rooftop HVAC installation.

What is a Rooftop HVAC Unit (RTU)?
A rooftop HVAC unit is a self-contained heating, cooling, and ventilation system designed for commercial buildings. These units are installed on the roof, making them space-efficient and easy to maintain. Rooftop installation in Toronto and the GTA is particularly popular due to its compact, all-in-one design. Unlike traditional split systems, RTUs do not have separate indoor and outdoor units. Instead, all essential components are housed within a single weather-resistant, durable casing that protects against debris, rain, and snow.
When to Upgrade Your Commercial Rooftop Unit ?
If your commercial HVAC system in Toronto shows any of the following signs, it may be time for an upgrade:

• Higher Electricity Bills Than Usual. An aging rooftop unit can lose efficiency, leading to increased energy costs.
• Strange Unusual Noises Coming from the RTU. Strange sounds from your RTU may indicate mechanical issues
• Frequent Breakdowns and HVAC Costly Repairs. Any commercial equipment repair in Toronto and the GTA is pretty expensive. If repair costs exceed 20% of the price of a new unit, an upgrade is recommended.
