Gas vs Electric Heating Systems in Ontario Homes

Choosing the right heating system is one of the most important decisions for homeowners in Ontario.
With long, cold winters and months of heavy furnace use, your heating system directly affects your home’s comfort, energy costs, and overall efficiency.
Two of the most common options for residential heating are gas and electric systems.
Each has its own advantages and disadvantages, and the best choice often depends on factors like home size, energy costs, and long-term efficiency goals.
Understanding the differences between gas and electric heating can help Ontario homeowners make an informed decision.
How Gas Heating Systems Work
Gas heating systems typically use a natural gas furnace to generate heat.
The furnace burns natural gas to produce heat, which is then distributed throughout the home using ductwork and vents.
Gas furnaces are widely used in Ontario because natural gas is commonly available and relatively affordable compared to electricity.
Modern high-efficiency gas furnaces can convert over 90 percent of their fuel into usable heat, making them a popular choice for colder climates.
These systems are designed to quickly heat homes even during extremely low outdoor temperatures.
How Electric Heating Systems Work
Electric heating systems generate heat using electricity rather than burning fuel.
There are several types of electric heating systems, including electric furnaces, baseboard heaters, and heat pumps.
Electric furnaces work similarly to gas furnaces but use electric heating elements instead of gas combustion.
Baseboard heaters and electric radiators heat individual rooms rather than the entire home through ductwork.
Electric heat pumps are becoming increasingly popular because they provide both heating and cooling while using less energy than traditional electric resistance heating.
Energy Efficiency Differences
Energy efficiency is often one of the biggest considerations when choosing between gas and electric heating.
Electric heating systems convert nearly all the electricity they use into heat, making them technically very efficient.
However, electricity itself is usually more expensive than natural gas in Ontario.
Gas furnaces, especially high-efficiency models, provide powerful heating while often costing less to operate over time.
For larger homes that require substantial heating throughout the winter, natural gas systems often result in lower monthly energy costs.
Heat pumps, however, can offer excellent efficiency and may reduce electricity usage compared to traditional electric heating systems.
Heating Performance During Cold Winters
Ontario winters frequently bring freezing temperatures and heavy snowfall.
In these conditions, heating performance becomes extremely important.
Gas furnaces are known for their ability to produce strong, consistent heat even during extremely cold weather.
They can quickly warm large homes and maintain comfortable indoor temperatures throughout long winter periods.
Some electric heating systems, particularly older models or baseboard heaters, may struggle to heat larger homes efficiently during very cold temperatures.
However, modern cold-climate heat pumps have improved significantly and can perform well in colder regions.
Installation and Equipment Costs
Initial installation costs can vary between gas and electric heating systems.
Gas furnaces often require additional infrastructure, such as gas lines and ventilation systems, which can increase installation costs.
However, many Ontario homes already have natural gas connections, making furnace replacement relatively straightforward.
Electric heating systems typically have lower installation costs because they do not require gas lines or combustion venting.
Electric baseboard heaters are especially affordable to install.
That said, lower installation costs may be offset by higher monthly energy expenses depending on electricity rates.
Maintenance Requirements
Both gas and electric heating systems require regular maintenance to ensure safe and efficient operation.
Gas furnaces require routine inspections to check burners, heat exchangers, and gas connections.
Professional maintenance is important for both performance and safety.
Electric heating systems generally have fewer mechanical components, which can mean less frequent maintenance.
However, systems like heat pumps still benefit from regular servicing to maintain efficiency and reliability.
Regardless of the system type, annual inspections are recommended before the winter heating season.
Environmental Considerations
Environmental impact is another factor many homeowners consider when choosing a heating system.
Electric heating systems produce no emissions inside the home because they do not burn fuel.
Depending on how electricity is generated, they may result in lower overall carbon emissions.
Gas furnaces rely on fossil fuels and produce emissions as part of the combustion process.
However, modern high-efficiency gas furnaces are significantly cleaner than older models and remain one of the most practical heating options for cold climates.
As renewable energy sources continue to grow, electric heating systems may become even more environmentally friendly in the future.
Which Heating System Is Best for Ontario Homes?
Both gas and electric heating systems can provide reliable warmth during Ontario’s cold winters.
The right choice depends on several factors, including energy costs, home size, existing infrastructure, and personal preferences.
Gas furnaces are often the preferred option for larger homes because of their powerful heating performance and lower operating costs.
Electric heating systems may be suitable for smaller homes, condos, or properties where natural gas service is unavailable.
Homeowners considering a new heating system should consult with a qualified HVAC professional to evaluate their home’s heating needs and determine the most efficient option.
Final Thoughts
Ontario homeowners rely heavily on their heating systems to stay comfortable throughout the winter.
Understanding the differences between gas and electric heating can help you choose the right system for your home.
Whether upgrading an older furnace or installing a new heating system, selecting the right equipment and maintaining it properly can improve comfort, reduce energy costs, and keep your home warm during even the coldest months.
All staff concerned were total professionals. Sales rep Dave was like having an old friend at your house. No up selling or pressure, just good honest facts and figures. The owners and assistant who installed our unit worked quietly, efficiently and left our home clean. We could not have been happier with the service and attention we were given. We are so happy a family member recommended Twintech. She said "don't call anyone else, just call them...they are amazing". And they were!!! Thank you guys for the great work!!! A. Johnson
We are completing a large project adding an addition on to our house and couldnt be more pleased with our decision to trust Twintech with our hvac work. They removed and replaced the furnace, installed a new A/C unit, swapped our tank water heater for a tankless unit, and completed ducting and new A/C lines through the addition. Without hesitation we would recommend Twintech to anyone.
Honest, very personable , men of their word ,workmanship xcellent ,showed up when promised ,They do not try to up sell ,rather give good advice instead . Price was very fair in my opinion .We have a family member with a medical condition and I think they made us a priority .Very happy with these guys . (Nice guys ) Stu Leffler Ajax.
Very professional, courteous, knowledgeable staff. Sales staff (David Gergley) excellent in knowledge and getting the job setup and installation was very prompt. Greg and Peter (technicians) knew their stuff and stuck around after completion to make sure it all worked properly and that I understood how it all was installed and how the unit worked. Would highly recommend them! Thanks for a great job-house is now cool and comfortable.
I had Twintech install a brand new air condition back in June of this year and I'm very happy with their service. I have a very busy schedule so I sent out an email to 7 or 8 HVAC companies just to get an idea of what it would cost. Dave at Twintech and only one other company were able to give me an approximate quote through email. Many of the companies I reached out to didn't even respond. I decided to meet with Dave and he was very friendly and professional. He gave me a good quote for a name brand/energy efficient AC with installation from their certified technicians. It was an easy decision to go with them.
Within a week I had the unit installed and working perfectly. Their technicians were very helpful and answered all of my questions. I'll definitely be calling them back for all of my HVAC needs in the future.
The people from Twintech were very friendly and personable...from the salesman to the installers. The installation was done as scheduled. I love my new air conditioner. My neighbour has a York and that thing is so noisy compared to my Goodman!! Thanks Twintech!!
Thank you, Twintech. They installed an A/C in my home in the middle of a heat wave which we appreciated very much. I found the team good, not overly friendly, other than the brothers. Dave, the salesperson was awesome, and, it's because of him that I was sold on using Twintech. I had other questions about additional work I am curious about and would have liked them to follow up and provide a quote. Other than that, which ultimately is not related to the great work they did, I would definitely recommend them, although I don't believe they go outside of Durham (check with them).
We have used this company a few times so I can't remember exactly what we paid but I do know that their fees are always very reasonable.
The first time we called Greg was when our furnace conked out while we were away. He came right away, showed me the problem and fixed it immediately.
The second time was when we needed an air conditioner moved and lifted to a platform. Again, he showed up on time, completed the job quickly (including a new gas line) and the fee was very reasonable.
We have received a quote from Greg to replace the air conditioner and furnace and when we are ready to move ahead, we will be calling him.
I have no hesitation in recommending TwinTech!
Our rating for Twintech is 5/5 stars. They are very professional and efficient, and the transparency they maintain right from the preliminary assessment till the day of the work is a testament to their experience in the field. We had Twintech replace our air conditioning and furnace, and we appreciate the efforts taken by Greg.
After 18 years my Air conditioner died in the middle of a heat wave. I entered my information on Home Stars and within the hour Dave from Twin Tech responded and offered to meet me as soon as possible depending on my availability. Dave was very knowledgeable about the products Twin Tech offered and even though this was the first quote I received . I felt very comfortable in giving Twin Tech my business. maybe it was the professional approach. Needless to say that the crew with Greg and Grant arrived promptly at the time they committed to were very professional and within a few hours had the place cool. They cleaned up and one would never know that I had work done . I know that the System is new and I probably wont need to worry about it for some time. However with the professionalism displayed by the crew I feel assured that should I need to call for service Twin Tech will respond. I also know that should I need a new Heating system I will go with Twin Tech. Keep up the good work.

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.
Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!
Very pleased with the professional service that TwinTech Heating and Cooling provided in replacing my furnace. I got several quotes from different service providers. Their price was excellent and they explained the features very well. We are very glad we went with TwinTech and highly recommend their services.
We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!
TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!
