One Installation Mistake, Years of Expenses: Why the Quality of Commercial Heating Service Matters
In the commercial sector, heating is much more than a comfort—it’s a major budgetary line and a key factor in the smooth operation of a building. At AirGreen, we’ve often been called in after a heating system was poorly installed, leading not only to efficiency losses, but also to a significant increase in energy costs, sometimes up to 100%. These cases are not rare. In Montréal, Laval, Longueuil, the North Shore and South Shore, many commercial property owners are still suffering the consequences of avoidable HVAC installation errors. Here’s what you need to know.
Understanding the Impacts of a Poor Commercial Heating Installation
Immediate Energy Losses
A poorly installed heating system often leads to:
-
Poor air circulation, causing hot and cold zones throughout the building.
-
Overheating equipment that consumes more energy to compensate for the inefficiency.
-
Constant operation, which wears down mechanical components prematurely.
Hidden But Very Real Costs
What many building owners find out too late:
-
Electricity consumption doubles just to maintain a stable indoor temperature.
-
Increased maintenance: parts wear out faster, requiring frequent replacements.
-
Occupant discomfort: cold offices, employee complaints, reduced productivity.
Case Study: Complete Rework of a Faulty Installation in Laval
A few months ago, we were contacted for a commercial office building in Laval. The client complained about abnormally high Hydro-Québec bills, despite having a relatively new installation. After inspection, our team quickly identified several issues:
-
Improper sizing of the central heat pump, underestimating the building’s real needs.
-
Poorly sealed air ducts, causing major thermal losses.
-
Incorrect placement of thermostats, which disrupted automatic regulation.
We carried out a complete system reconfiguration, including the installation of a new Goodman R-32 system, precisely calibrated for the space to be heated. The result: a 42% reduction in energy consumption starting the very next month.
The Most Common Mistakes and Their Consequences
1. Installing an Undersized Unit
Many commercial buildings in Montréal and on the South Shore are equipped with units designed for residential use. The result: the system is always working at full capacity, never achieving optimal efficiency. This wears out the compressor prematurely and drives electricity bills through the roof.
2. Poor Thermostat Calibration
A misplaced or poorly programmed thermostat gives inaccurate readings. This leads to erratic heating cycles and increased consumption with no real comfort gain.
3. Inefficient Ductwork Installation
In many older buildings in Longueuil, we’ve found uninsulated, cracked, or undersized ductwork. This cancels out a large portion of the energy efficiency of even the highest-quality heat pump system.
4. Skipping Regular Maintenance
Even a perfectly installed system will lose efficiency without regular commercial HVAC maintenance. Clogged filters, dirty coils, pressure checks… all of it must be monitored.
Why Choose AirGreen for Your Commercial Heating?
Proven Expertise in Montréal, Laval, Longueuil, North Shore and South Shore
For over 15 years, we’ve been installing, repairing, and optimizing commercial HVAC heating systems throughout the Greater Montréal region. Our technicians are certified, experienced, and trained to work with the most trusted brands on the market: Goodman, Fujitsu, Bosch, Gree, Arcoaire, Lennox, Trane, ACD, and more.
Complete Thermal Analysis and Precise Sizing
Before any installation, we conduct a comprehensive thermal study of the building:
-
Volume analysis
-
Building orientation
-
Number of occupants
-
Potential thermal losses
This step is essential to avoid oversizing or undersizing the equipment—both of which are costly mistakes in the long run.
Help Securing Grants
Many of the systems we install are eligible for Hydro-Québec’s LogisVert subsidies for commercial buildings. We assist you in all administrative procedures to help you maximize your returns.
Tips to Avoid Expensive Mistakes
-
Don’t base your decision solely on installation cost: a cheaper heat pump that’s poorly suited will cost you more in the long term.
-
Have your ductwork inspected if you’re renovating or replacing an old system.
-
Request a load calculation report before signing anything.
-
Choose a local contractor with verifiable references in the North and South Shores.
Testimonial from a Building Manager on the North Shore
"We had installed a Bosch IDS Premium unit with a general contractor. Less than a year later, tenant complaints were piling up. AirGreen stepped in, recalibrated everything, corrected the ductwork, and set up an effective zoning system. The difference was immediate. Our bills dropped by 35%." — Simon B., Property Manager in Blainville
