These “Money-Saving” Tricks Actually Cost You More: The Real Price of Heating Mistakes in Longueuil
In Longueuil, many homeowners are looking for ways to cut down their heating bills, especially during the coldest months when costs can skyrocket. At AirGreen, we’ve helped hundreds of clients throughout the region, and we’ve seen that some seemingly smart decisions… end up doing more harm than good.
In this article, we’ll walk you through the 6 most common “smart” ideas we’ve encountered in Longueuil that ultimately lead to higher costs, less comfort, and even technical issues over time.
1. Relying on Portable Heaters as the Main Heat Source
Many Longueuil residents use portable space heaters in certain rooms to avoid heating the entire house. It sounds logical, but:
-
These units typically consume 1,000 to 2,000 watts per hour.
-
They’re not built for long-term use, increasing the risk of overheating or failure.
-
They don’t distribute heat evenly, which means persistent discomfort.
A real-life case: a client in Vieux-Longueuil contacted us after receiving an electricity bill over $600 in January. The culprit? Three electric heaters used daily.
The AirGreen solution: We installed a 12,000 BTU Fujitsu wall-mounted heat pump, eligible for a LogisVert grant. The result: consistent comfort throughout the home and a 43% reduction in electricity usage.
2. Dropping the Thermostat Too Much at Night
Lowering the thermostat at night is a common habit. But dropping it too drastically (more than 3–4°C) forces your system to work much harder in the morning, which:
-
Consumes more energy.
-
Wears down your equipment faster.
-
Can decrease thermal comfort when waking up.
A home in Saint-Hubert with an outdated central system experienced a furnace breakdown after weeks of extreme temperature swings. We installed a Lennox R-32 central heat pump, designed to maintain a stable indoor temperature at low energy cost.
3. Thinking an Old System “Still Works, So It’s Fine”
At AirGreen, we often see homes with HVAC systems that are 15 to 25 years old, often poorly maintained. Even if they still run:
-
Their energy efficiency is very low.
-
They may consume twice as much as a modern unit.
-
They are no longer eligible for new grants.
Example from Greenfield Park: we replaced a 1999 central A/C with a 2.5-ton Midea EVOX G3 heat pump. The homeowner received a $2,150 grant, and the estimated return on investment is under four years.
4. Neglecting Regular HVAC Maintenance
An HVAC system that isn’t maintained builds up dust, moisture, and debris, which:
-
Reduces efficiency by 15–30%.
-
Can lead to poor indoor air quality.
-
Speeds up component wear.
At AirGreen, we recommend annual HVAC maintenance, including coil cleaning, refrigerant level checks, and fan adjustments. This extends your equipment’s lifespan and ensures optimal performance year-round.
5. Relying Solely on the Thermostat to Save Money
A programmable thermostat helps, but it won’t fix an improperly sized or poorly distributed system. In Longueuil, we’ve seen homes with rooms that are too cold or too hot, even with smart thermostats.
The solution: a multi-zone system. Example: a three-story home in Boisé-du-Tremblay had one unit per floor installed with a 36,000 BTU Gree FreeMatch multi-zone heat pump. Result: even temperatures and 34% energy savings.
6. Thinking That Opening Windows “Airs Out” the House and Saves Money in Winter
Opening windows for 15 to 30 minutes in winter to “freshen the air” can undo hours of heating and create a thermal shock. It forces your system to start back up at full capacity, especially in poorly insulated homes.
At AirGreen, we recommend installing an air exchanger (HRV or ERV), which:
-
Provides continuous ventilation without heat loss.
-
Improves indoor air quality.
-
Can be integrated into your existing HVAC heating system.
