Choosing between a central heat pump and an electric furnace is a common decision in Quebec, especially when homeowners want to improve comfort without adding maintenance complexity. Both systems can heat a home effectively, but they operate in very different ways. That difference affects electricity consumption, comfort, humidity management, and seasonal flexibility. This guide clearly explains what sets these two options apart and how to choose based on your home, your needs, and your ductwork.
Summary of key points
- A central heat pump transfers heat and can also provide cooling, while an electric furnace generates heat using resistance elements.
- Under moderate conditions, a heat pump generally delivers more heat per unit of electricity consumed than resistance-based heating.
- An electric furnace is simple and reliable, but its efficiency is limited by its principle: one unit of electricity produces roughly one unit of heat.
- A heat pump is more sensitive to sizing, clearances, and maintenance because it relies on heat exchange and airflow.
- Both systems often use existing ductwork, but air balance and airflow become even more critical with a heat pump.
- During extreme cold, a system may rely on electric backup heating depending on configuration and control strategy.
- The best choice depends primarily on your home (insulation, size, ductwork), your priorities (cooling, stability), and your tolerance for maintenance.
Understanding how they work: generating heat vs transferring heat
Central heat pump: moving heat
A central heat pump does not “create” heat the way an electric resistance system does. It uses a refrigeration cycle (compressor, refrigerant, heat exchangers) to move heat between the outdoors and the home. In heating mode, it extracts heat from the outdoor air and transfers it indoors. In cooling mode, the process is reversed.
This principle explains its main advantage: when operating in favorable conditions, it can deliver more heat than the electricity it consumes.
Electric furnace: heating with resistance
An electric furnace heats air using resistance elements, then a blower pushes that warm air through the duct system. It is a simple and very predictable system: it converts electricity directly into heat. Its operation is generally stable, but it does not benefit from the “energy leverage” that a heat pump provides.
A simple way to remember this: a heat pump is a heat transporter, while an electric furnace is a heat generator.
Energy efficiency: what really changes consumption
The term “efficiency” can be confusing, so it helps to be specific. With resistance heating (electric furnace), electricity is converted directly into heat. With a heat pump, electricity powers the compressor and fans that transfer heat.
Why a heat pump can use less electricity for heating
Under moderate outdoor temperatures, a heat pump can deliver more heat for the same amount of electricity. In practical terms, that means it can often provide similar comfort while consuming less electricity than an electric furnace, especially in fall, spring, and during average winter conditions.
What happens during very cold weather
As outdoor temperatures drop, a heat pump must work harder to extract heat, and its capacity or efficiency may decrease depending on the equipment and conditions. In many systems, an electric backup heater supplements the heat pump temporarily or partially to maintain comfort.
The key takeaway is this: a central heat pump delivers most of its benefits over a large portion of the heating season, while an electric furnace provides very consistent output without efficiency gains.
Comfort: stability, air distribution, and humidity
Comfort is not only about heat output. It also depends on temperature stability, airflow, and humidity management.
Temperature stability and heating cycles
Many modern central heat pumps can modulate their output, depending on technology, which promotes smoother and less abrupt heating cycles. An electric furnace typically operates in on-off cycles based on thermostat demand. These cycles can still be comfortable when the thermostat and air distribution are properly adjusted.
Indoor humidity in winter
In winter, outdoor air is naturally dry. When it is heated indoors, relative humidity drops regardless of the heating system. A heat pump does not inherently dry the air more than an electric furnace. Perceived dryness depends mainly on:
- indoor temperature (overheating feels drier),
- ventilation and air exchanges,
- air circulation throughout the home.
The importance of ductwork (often underestimated)
In both systems, ductwork must be in good condition, properly sized, and well balanced. With a heat pump, airflow and heat exchange are even more critical. Insufficient airflow can reduce performance and comfort.
Installation and maintenance: what to expect
Central heat pump
A central heat pump requires a more technical installation: outdoor unit placement, clearances, snow management, defrost operation, connections, and control settings. Maintenance focuses on preserving airflow, keeping heat exchangers clean, and ensuring stable operation.
Electric furnace
An electric furnace is generally simpler: no outdoor unit, fewer external components, and maintenance focused on cleanliness, filters, and electrical elements. It is often chosen for its straightforward operation.
Regardless of the system, proper maintenance reduces energy use and helps prevent unexpected issues.
- Check filters and return air grilles regularly.
- Keep supply registers unobstructed.
- Schedule an inspection if you notice new noises, abnormal cycles, or persistent cold spots.

How to choose based on your situation
There is no universal “best” system. The right choice depends on your goals and your home.
Home with ductwork and a need for air conditioning
If you want one central system for both heating and cooling, a central heat pump has a structural advantage: one system serves two seasons.
Well-insulated home seeking stable comfort
In a home that retains heat well, a heat pump can take full advantage of its efficient operating range, often delivering stable comfort when airflow is properly balanced.
Priority on simplicity and consistency
If your main priority is a very simple system with no outdoor unit and highly predictable operation, an electric furnace may be appropriate in certain configurations.
Home with cold zones and uneven airflow
In this case, improving air balance, circulation, and airtightness should come before changing equipment. Otherwise, the same comfort issues may persist regardless of the system chosen.
Table 2 – Decision support by priority
| Main priority | Often the more coherent option | Why |
| Central heating and cooling | Central heat pump | One system for two seasons |
| Simplicity, no outdoor unit | Electric furnace | Direct, straightforward system |
| Lower consumption in moderate weather | Central heat pump | More advantageous heat transfer |
| Stable comfort, fewer fluctuations | Central heat pump (well configured) | Often smoother operation |
| Low tolerance for maintenance | Electric furnace | Generally simpler upkeep |
Conclusion
The main difference between a central heat pump and an electric furnace lies in their operating principle. One transfers heat and provides cooling, while the other converts electricity directly into heat for space heating only. In Quebec, a central heat pump can offer lower electricity use over much of the winter and provide summer comfort, but it requires more careful installation and maintenance. An electric furnace remains a simple, consistent option, particularly appealing to homeowners who prioritize straightforward operation.

Frequently Asked Questions
Does a central heat pump always replace an electric furnace?
Not necessarily. Depending on the configuration, the furnace may serve as backup or be fully replaced. The strategy depends on the home, local climate, and comfort goals.
Can a central heat pump work with existing ductwork?
Often yes, but duct condition, airtightness, and especially airflow must be verified. Poor distribution can limit comfort and efficiency.
Can an electric furnace provide air conditioning?
No. It provides heating only. Central air conditioning requires a dedicated cooling system or a heat pump.
Which system is quieter?
Both can be quiet when properly installed. Vibrations, placement, and air distribution have a strong influence on perceived noise.
What maintenance has the greatest impact on energy use?
For both systems: filters, clear return air paths, and unobstructed registers. For a heat pump, keeping the outdoor unit clear in winter is also essential.
