Smart Thermostat: Why This Solution Alone Won’t Guarantee the Promised Savings on Air Conditioning

Maximize Your Energy Savings: A Smart Thermostat Isn’t Enough!

In the commercial sector of Montréal, Laval, Longueuil, and both the North and South Shores, reducing energy costs has become a major strategic priority. Many companies and property managers are now investing in smart thermostats, tempted by the attractive promise of substantial savings on air conditioning. Yet, at AirGreen, we frequently observe that this technological solution alone is far from sufficient to guarantee the anticipated savings.

Smart Thermostat: Understanding Its Limits to Better Utilize It

A smart thermostat allows for more precise management of your air conditioning or heating system by automating temperature settings based on user habits or weather conditions. While it indeed represents a technological advance, this type of thermostat cannot compensate for certain structural or technical problems often overlooked during installation.

The main factors limiting the real effectiveness of smart thermostats are:

  • Poorly sized or outdated air conditioning equipment

  • Inadequate or obsolete HVAC installations

  • Insufficient or irregular maintenance of air conditioning units

  • Ignored insulation or ventilation problems in older buildings

Real Case in Longueuil: Promised Savings That Never Arrived

A commercial building located in Longueuil on the South Shore recently reached out to us after installing several high-end smart thermostats without experiencing the expected reduction in energy costs. During our evaluation visit, we quickly identified the true sources of their excess energy costs:

  • An outdated and undersized central heat pump (obsolete brand and model)

  • Uninsulated ventilation ducts causing significant heat loss

  • Poor initial calibration of smart thermostats, resulting in continuous operation of units

Given these findings, we proposed a comprehensive action plan far beyond just installing smart thermostats.

The Importance of a Complete and Proper HVAC Installation

At AirGreen, our expertise in commercial HVAC installation in Montréal and surrounding areas allows us to offer comprehensive solutions that truly meet our clients' economic expectations. Here’s what we implemented in Longueuil:

  • Replaced the aging heat pump with a modern unit, the Gree Extreme central heat pump rated at 36,000 BTU, particularly suited for Québec’s harsh climate

  • Improved duct insulation and meticulously inspected the ventilation network to eliminate unnecessary energy losses

  • Optimally calibrated the smart thermostats to maximize their actual potential and long-term energy efficiency

Thanks to these interventions, our client finally achieved the substantial savings initially promised.

Why Combining Smart Thermostats with Optimized HVAC Installation Is Essential

By analyzing numerous installations completed in Laval, Montréal, and Longueuil, we’ve demonstrated that smart thermostats only deliver their full benefits when operating within a healthy and optimized HVAC environment.

Here's how to concretely maximize your energy savings:

  • Check the overall condition of your HVAC system before installing smart thermostats.

  • Replace outdated equipment with recent, energy-efficient models adapted to local standards.

  • Strengthen duct insulation and ensure airtightness to minimize thermal losses.

  • Perform regular preventive maintenance to optimize your system’s efficiency and lifespan.

Client Testimonial: AirGreen’s Comprehensive Approach Makes the Difference

A commercial building manager in Laval clearly attests to the results obtained from our comprehensive approach:

“After following AirGreen’s advice and opting for a fully optimized HVAC installation in addition to our smart thermostats, our energy costs dropped by nearly 40%. AirGreen’s expertise clearly made the difference: our only regret is not starting there!”

Mistakes You Absolutely Need to Avoid

To ensure you avoid the most common pitfalls, here's a list of frequently observed mistakes when installing smart thermostats:

  • Believing that a smart thermostat can compensate for poor insulation or incorrect HVAC sizing.

  • Neglecting compatibility between your smart thermostat and current equipment.

  • Failing to carefully perform initial calibration, drastically reducing its effectiveness.

  • Ignoring regular equipment maintenance, causing premature wear and increased energy consumption.


Conclusion: A Smart Thermostat, Yes, but Only with an Optimized HVAC Installation!

At AirGreen, we firmly believe installing a smart thermostat is an excellent decision, provided it’s part of a comprehensive and optimized HVAC strategy. Only this combination guarantees the promised savings and genuine user satisfaction.
