FAQ'S
Commonly Asked Questions.
A rooftop HVAC unit (RTU) is a self-contained system installed on the roof of commercial buildings to provide heating, cooling, and ventilation. RTUs draw in outdoor air, condition it, and distribute it throughout the building. They are ideal for offices, warehouses, restaurants, and retail spaces because they save indoor space and deliver efficient comfort year-round.
Upgrading to a modern RTU offers lower energy bills, improved air quality, quieter operation, and fewer repairs. High-efficiency RTUs also reduce your carbon footprint and may qualify for government rebates in Ontario, making them a smart investment for businesses.
Commercial rooftop units should be serviced at least twice a year — typically in spring and fall. Preventive maintenance helps identify issues early, improves energy efficiency, reduces the risk of breakdowns, and extends the lifespan of your RTU.
Warning signs include rising energy bills, uneven heating or cooling, frequent breakdowns, loud noises, and poor indoor air quality. If your RTU is more than 15 years old or requires costly repeated repairs, replacement with a high-efficiency unit is often more cost-effective.
Yes. Many Ontario utility providers and federal programs offer rebates for businesses that upgrade to high-efficiency rooftop HVAC systems. These incentives can significantly reduce upfront costs while helping your business save long-term on energy expenses. LG Mechanical can assist with rebate applications.
