Commercial ventilation contracts


Guaranteed Industries delivers top quality climate control and ventilation systems to the architects, engineers and general contractors who depend on us. We design and install air conditioning, heating, ventilation, humidification, heat recovery and energy management systems for some of Montreal's largest projects. Our managers and technicians supervise every stage of a project from the design phase through to the installation. We keep an eye on things to make sure that deadlines are met and projects stay on budget. 

Keeping pace with our industry's latest advancements is one of our priorities. Today's builders are using green technology to increase energy savings and ensure healthy air quality. We provide them with our up-to-date expertise and products. Our staff of designers and licensed technicians constantly participate in upgrade and training courses in oder to keep up with the latest advances in technology.

Residential Air Conditioning


Today's homeowners are not only concerned about the comfort of their homes, but also a healthy environment. Advancements in engineering and technology continue to improve our air quality, heating and cooling products. High-efficiency heating and air conditioning systems, such as Lennox Residential HVAC, save both energy and money. Filtration systems and humidifiers help keep the house air quality clean and healthy. And, ductless systems are efficient in keeping homes cool without ventilation.
