Commercial Heating and Energy Savings: Debunking 5 Costly Misconceptions

Optimizing commercial heating without compromising performance or driving up costs is a challenge we tackle every day at AirGreen. And yet, we regularly encounter business owners, building managers, and facility directors across Montréal, Laval, Longueuil, the South Shore and the North Shore who hesitate to upgrade due to persistent misconceptions. These false beliefs about heating systems can lead to inefficient, costly long-term decisions—or even damage your equipment’s longevity. That’s why we’ve put together this in-depth article to debunk five common myths about commercial heating, so you can make smarter choices that benefit both your comfort and your bottom line.

Energy-efficient systems are always more expensive up front

One of the most widespread myths is that high-efficiency commercial heating systems are simply too expensive to install. But this perspective overlooks the total cost of ownership. Central commercial heat pumps, especially high-performance models from brands like Fujitsu, Bosch, Lennox, or Arcoaire, not only deliver significant energy bill savings but also qualify for attractive grants through Hydro-Québec’s LogisVert program.

At AirGreen, we recently installed a Fujitsu AIRSTAGE VRF central heat pump in an office building in Longueuil. Thanks to its high coefficient of performance (COP), the system efficiently heats large open spaces while consuming far less electricity. The initial investment was quickly offset by a nearly 40% reduction in annual heating costs.

Old systems still work, so no need to replace

Many property managers delay upgrading an aging heating system simply because it’s “still working.” But this kind of change resistance can result in energy leaks, increasing maintenance costs, and a higher risk of breakdowns right in the middle of winter.

At a commercial grocery store in Laval, we recently replaced an outdated oil furnace with a Bosch BOVA 5-ton central heat pump running on R-454B refrigerant, which is far more eco-friendly. The result: immediate savings on maintenance, more mechanical space, and noticeably improved indoor air quality. On top of that, the client received a $5,000 grant, making the upgrade not just logical, but profitable.

The more powerful the system, the better

There’s a common misconception that an oversized unit will deliver better comfort or superior performance. Not true. A system that’s too powerful for a building’s actual needs will run in short cycles, leading to premature wear, temperature inconsistencies, and higher operating costs.

At AirGreen, we always perform a thorough thermal load calculation before any installation. In Montréal, at a dental clinic, we installed a 3-ton Lennox central heat pump, perfectly matched to the building’s specific requirements. The result: consistent comfort in every treatment room, significant energy savings, and a maximized system lifespan. And all of it backed by proactive annual maintenance.

Commercial heating systems can’t be eco-friendly

Another harmful myth: that you can’t combine commercial heating and environmental responsibility. In fact, the latest generation of central heat pumps, running on next-gen refrigerants like R-32 or R-454B, emit far fewer greenhouse gases while being significantly more efficient.

In Saint-Hubert, on the South Shore, we retrofitted a warehouse with a 60,000 BTU ACD central system running on R-32 refrigerant. This upgrade not only cut the building’s carbon footprint by 35%, but also earned the client EcoResponsible recognition from the City of Longueuil. And thanks to a local energy transition program, they also received financial assistance.

Maintenance can wait: if it’s heating, it’s fine

Finally, a truly costly myth: delaying preventative maintenance. In commercial settings, an unexpected breakdown during a cold snap can have serious consequences—loss of business, discomfort for staff and customers, even equipment damage.

At AirGreen, we offer custom CVAC maintenance contracts tailored to your business hours and your building type (retail, office, institutional, industrial). In Boisbriand, on the North Shore, a call center entrusted us with the annual maintenance of their 48,000 BTU Gree central system. The result: zero breakdowns over three years, consistent performance, and substantial savings on replacement parts.

The bottom line: choose smart energy strategies

Modern commercial heating solutions can now deliver energy savings, performance, reliability, and environmental responsibility all at once. But to unlock those benefits, you need informed decisions based on rigorous assessment, professional installation, and regular follow-up.
