Common Mistakes We See With Commercial and Industrial HVAC Systems


We have over 30 years of experience with commercial and industrial HVAC in Toronto and the Greater Toronto Area, so we’ve seen our fair share of HVAC system errors and oversights. The complexity of air conditioning, heating, and ventilation systems in large-scale facilities is significant, so minor mistakes can lead to major energy waste, reduced performance, and lower indoor air quality—plus expenses from extra repairs and shorter equipment life.

Today, we’re going to explore some of the most common mistakes we encounter in commercial and industrial HVAC installations, repairs, and set-ups. Thankfully, most of these errors are easy to avoid if you partner with the right HVAC contractor.

Improper System Sizing

One of the most critical steps in ensuring efficient HVAC performance is proper system sizing. Both undersized and oversized systems can lead to energy waste, frequent breakdowns, and short-cycling that severely affects equipment lifespan. An undersized system will struggle to meet the heating or cooling demands of the space, while an oversized system heats or cools a space too quickly, leading to short-cycling. We use precise load calculations to determine the optimal size of the HVAC system needed for your facility.

Incorrect Installation

Even the best HVAC system will work poorly if it isn’t installed right. Common installation errors include poor placement of thermostats and sensors, incorrect duct sizing, and improper sealing and insulation of ductwork. These issues can lead to uneven heating or cooling, higher energy bills, and strained HVAC components. Our team ensures that each system is installed according to manufacturer specifications and industry best practices.

Neglecting Maintenance

Regular maintenance is the backbone of any efficient and long-lasting HVAC system. The maintenance needs to be more than regular, however. It also needs to be specially tailored to the equipment and facility, not just a boilerplate checklist. We offer customized maintenance plans with a dedicated account manager and technicians so you get the best possible maintenance.

Overlooking Indoor Air Quality

Indoor air quality (IAQ) is crucial for the health and comfort of building occupants, facilitate process, and protect equipment. However, it’s often neglected in the setup of HVAC systems. Common mistakes include not integrating adequate ventilation or air filtration systems, leading to negative air pressure in a building. We emphasize the importance of IAQ in our HVAC solutions, providing options for advanced filtration and ventilation to ensure a healthy, productive indoor environment.

Inadequate Energy Management

Energy efficiency is beneficial for reducing operating costs, but we’ve seen many mistakes such as using outdated technology, failing to implement energy management systems, and ignoring programmable controls. We focus on the most advanced in building automation systems for energy management that exceed expectations.
