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.
Very impressed with this company. They show up on time , kept my place clean and after they left it looks like they were never there. Very professional team. Those people know what they doing . Their installation was on the highest standard. They are very knowledgeable especially they're worker Peter. I strongly recommend this company to everybody. After the installation I receive the call making sure I'm satisfied with their products and their job. Bravo!!!
Greg and his brother were referred to us by a friend. They arrived when they said they would, did an exceptional job and left the place as tidy or tidier then they found it. Their professionalism is only surpassed by their kind and friendly demeanor. Even after several calls to help me with my high tech thermostat I feel that I could always call with any concern (No one responds to my texts as quickly as Greg) and have a friendly helpful response. I found out their grandfather started the company and now as a 3rd generation company, they are doing their grandfather proud. I would highly recommend Twintech over any other hvac company out there.
Thanks to the guys at Twintech Heating for a great job installing a new hot water tank. They set a time and day to remove the old tank and install the new one. They were on time and had the work done quickly and cleaned up after they were finished. Excellent work and great value.
In November, we contacted Twintech for a quote on a high efficiency furnace plus installation. Dave, the sales representative for the company was very friendly and informative. Upon arrival at our home, he willingly showed us his company licenses, clearly explained the operation of a high efficiency furnace and answered all our questions to our satisfaction. As well, Dave was the only sales representative that we contacted that was willing to make the arrangements for an energy audit. For us, this was a big plus as we found the government rebate program somewhat confusing to navigate. The furnace was installed on the date that was arranged in an efficient and professional manner by Greg (the owner) and Peter. Both men worked diligently, throughout a long day to complete the job and upon finishing, left the job site immaculate. When a neighbour raised concerns about the furnace venting location, Greg located an alternative location and resolved the situation with diplomacy. We chose the Napoleon furnace for its excellent warrant;y on the heat exchanger and because it was made in Canada! In addition, to the furnace warranty, Twintech offered us a 5 year warranty on labour which speaks to the quality and pride this team has in their workmanship. It has been over a month now (with some of the coldest January days on record) since we have had the furnace installed. The furnace runs quietly and distributes heat more evenly throughout our 90 year old Toronto home. We can't speak highly enough of the Twintech team and are very satisfied with their workmanship and job ethics. We have no hesitation about recommending them.
What more could you ask for! Grant and Greg Dainty provided a professional,diligent and thorough approach to the installation of my furnace. I would highly recommend there services.
Last week our Furnace failed overnight. We called Twintech to help us get it running again. They did a really thorough check on it, and got it running in less than an hour. Given that it was an old Furnace (+20 years old), we were giving two options: repair it or replace it. Instead of doing a repair on it that could break in a week or two, they recommended us to change it. I like that they were honest on the recommendation, not forcing a new furnace on us. At the end we went with a new Furnace. Twintech solutions service & salesman gave us recommendation on the size of the unit and many options that could work for our home. They ended up doing an excellent work in our furnace, replacing the filter to a better option and replacing some pieces that had water damage. They cleaned after themselves and leave everything even better than what they found. They even went far and beyond tiding up the hose connections that we had on the basement.
I am in the process of finishing my basement and wanted to make sure I got the low hanging duct work fixed in advance. After reviewing 5 quotes I selected Twintech to award the contract to. The price was competitive however what won me over was Grant's (co-owner) attention to detail and his ability to focus on what my goals and priorities were for the project. His team completed the job over 3 days as there was significant duct work changes and the relocation of all of the equipment. They also completed the job with little downtime so we weren't left overnight without heat during freezing winter temperatures.
My father woke up to no heat one Saturday morning. We had a few names that friends had recommended but while checking out the companies' ratings on HomeStars, we found Twintech with great ratings too. The other companies either didn't get back to us or didn't have time to come at such short notice. TwinTech made the time in their schedule for what they judged to be an emergency: no heat in the home of an elderly person. At no extra fee for a short notice, weekend visit. They recommended an upgraded furnace unit and explained that we would qualify for a rebate that would bring the price down to that of a lower model. They set us up with the rep from the MNR that covers the rebate so that we didn't have to deal with the paperwork & phone calls ourselves. Installation was quick, efficient, & smooth. We were so pleased with their service we ordered a new water heater too. Both are working great (efficient & quiet!) & my father is safe & comfortable. We can't say enough about how pleased we are with their service. We have already recommended them to others.
Twintech Heating & Cooling. I just want to say thanks for helping me . My Furnace stopped working. And l phone Dave Getgley he set me up with Greg. What an amazing team they did a great job in setting me up with a new Furnace. Anyone that needed a new Furnace these are the guys to call. Thanks again for a job well done.
Our home has had poor heating and air conditioning the past couple of years. Dave recommended a Goodman solution with more power than we had. Grant and Greg installed the units in late November. Heating is better than ever. We have a warm home again and look forward to the winter. Can't wait to see how the AC runs in 2018. Job was super clean and professionally done. Highly recommended.

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!
