Replacing an Old Oil Heating System: A Smart, Eco-Friendly and Strategic Decision
At AirGreen, we assist many homeowners throughout Montréal, Laval, Longueuil, the South Shore and the North Shore in making a transition that’s become essential: replacing an old oil heating system with a high-performance electric system. This energy shift isn’t only driven by environmental concerns or government regulations—it’s also based on real economic logic: lower costs, improved energy efficiency, access to major financial grants, and enhanced indoor comfort.
Let’s take a deep dive into everything you need to know about this important energy transition.
Why Ditch Oil Heating?
An Expensive and Polluting Energy Source
Heating oil, although historically common in many residential and commercial buildings in Quebec, is now outdated. It’s heavy, expensive, polluting, and requires complex maintenance. On top of that, the price of heating oil fluctuates heavily depending on global markets, making bills unpredictable for property owners.
A Government-Backed and Subsidized Environmental Shift
The Quebec government, along with many municipalities like Montréal, Laval, and Longueuil, are actively encouraging the phase-out of oil heating. Several financial assistance programs are available, most notably Hydro-Québec’s LogisVert program, offering grants that can reach several thousand dollars to help homeowners make the switch.
The Advantages of Switching to Electric Heating
Significant Long-Term Savings
A high-performance central electric heat pump, such as those from Bosch, Fujitsu, Goodman, or Trane, can cut annual energy costs by up to 40%. These systems combine heating and cooling into one, delivering year-round efficiency.
Better Energy Efficiency
Modern electric heat pumps boast high SEER and SCOP ratings, meaning excellent performance in all seasons. They're built to perform even in harsh Quebec winters—down to -30°C for some models like the Bosch BOVA or the Fujitsu KZAH R-32.
Added Property Value
A building heated by electricity with a modern heat pump is far more appealing to potential buyers. It’s a significant value booster in today’s real estate market, where energy efficiency is increasingly important.
The Cost of Converting from Oil to Electricity
The total cost depends on several factors:
-
Size of the home or building
-
Existing distribution system (forced air, hot water, etc.)
-
Type of heat pump chosen
-
Installation complexity (ductwork upgrades, electrical panel upgrades, etc.)
General Estimates
| Type of Conversion | Approximate Cost (Before Grants) |
|---|---|
| Oil to Central Heat Pump | $12,000 to $20,000 |
| Oil to Dual-Energy (with Hydro-Québec’s DT Rate) | $10,000 to $18,000 |

Real Example: Conversion in Laval of a Duplex from Oil to Bosch Heat Pump
A client in Chomedey (Laval) recently contacted us to replace their aging oil system with a Bosch BOVA 36,000 BTU central heat pump, a high-efficiency model using R-454B refrigerant.
Technical Challenges:
-
The existing ductwork was outdated and needed modification.
-
The oil tank had to be removed and neutralized.
-
An electrical panel upgrade (to 200 amps) was necessary.
Result:
-
43% reduction in annual heating costs
-
LogisVert grant of $5,710 secured
-
Installation completed in 3 days, with no major comfort disruptions
-
Improved acoustic comfort, thanks to the ultra-quiet inverter compressor
Practical Tips for a Successful Conversion
