We are a highly experienced HVAC Company and have worked with various businesses throughout Toronto. We have been in the industry since 1964 and have worked on all major types of boilers within different types of commercial buildings. What makes us one among the leading HVAC companies in Toronto is our pricing. We provide efficient heating, ventilation and air conditioning solutions at very affordable prices. 

We provide regular training to our staff so that we are up to date with all the latest technologies and can provide the best services to our clients. Our technicians are very experienced and well trained to install and service almost all types of commercial heating systems.  

What We Do

At Dupont Heating & Air Conditioning, we provide the following commercial heating services:

Boilers - We service and install top-class hydronic systems. The heat produced via hydronics offers healthier and consistent heating throughout your home. There are zero to minimal dust particles in the air and no temperature difference from level to level! Achieve greater home comfort with a hydronic system. We carry high-quality hydronic equipment.

Hot Water Tanks - We install and service hot water tanks/heaters of all make and models. We use industry-leading brands for our heating products. We also install and maintain tankless water heaters.

Rooftops - We install, repair, and maintain rooftops for many homeowners in Toronto. 

Custom Ductwork - There are many customized forms of air ducts. Choosing custom sheet metal fabrication increases durability and flexibility. Sheet metal prevents water damage and has good airflow properties. Aluminum ductwork can also be used for HVAC systems as it is lightweight. Our expert technicians can design durable, unique ducting solutions.

Repairs & Replacements

Well-functioning heating and cooling systems are crucial for operations in any commercial setting such as an office or a restaurant. When your HVAC system breaks down, you risk leaving a wrong impression on your customers and clients. We help you avoid this by providing comprehensive and swift repairs with minimal response times. When carrying out your commercial HVAC repair in Toronto, we always offer long-lasting solutions so that you don't have to call for repairs again.


Although we try our hardest to repair your system, sometimes a replacement is more cost-effective and even necessary. We can work with most makes and models, and our team has the training to replace systems on all types of commercial properties.

HVAC Maintenance

At Dupont Heating & Air Conditioning, we believe prevention is better than cure. Here are some advantages to scheduling regular maintenance for your HVAC system:

  • Energy savings: A poorly functioning HVAC system puts a lot of stress on the different parts and components in the system. This unnecessarily increases your energy costs. Regular maintenance will ensure that your HVAC system functions like a well-oiled machine.

  • Optimized functioning: A well-maintenance HVAC system will perform well, with the hot and cold air being distributed evenly. It helps you avoid the risk of an icy cold conference room or a stuffy restaurant.

  • Longer life: It's no secret that a properly maintained HVAC system lasts longer than one that has no maintenance. With regular maintenance appointments, you can avoid the costs of an expensive replacement.

  • Improved air quality: A neglected heating system will eventually become the breeding ground for mould, mildew and bacteria. These elements in your HVAC system will negatively impact the health of those on your property. Regular cleaning and maintenance will prevent this and ensure cleaner air.
