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 interactions from sales to installation were Courteous and professional. The installation was seamless and the attention to detail including clean up was outstanding. I highly recommend TwinTech Heating and Cooling.
Twintech's Salesman Dave arrived promptly was friendly and courteous, listened and assured us the installation would be completed according to our requests. The crew arrived early morning on May 11th, 2018 and worked through till late afternoon non-stop. They were very friendly, very professional, their expertise was excellent, their workmanship outstanding and the installation was completed in a timely and efficient manner. We were completely satisfied and happy with the quality of the work.
I had cold and hot spots all over my 70 yr old home. My furnace is quite new and Greg optimized the fan and furnace. The original installer just took it out of the box with factory settings and installed it- basically running at 50% of capacity. Greg also routed heat into my laundry room, yeah - so now I can renovate laundry room - thanks Greg. He is honest, professional and knowledgeable. I will be calling him back in the spring to optimize my AC as well.
Wonderful from beginning to end. I tend to fret and worry about home improvements but the excellent team at TwinTech put my mind as ease. They listen, they are patient and best of all ... the work they did is amazing! I chose the Goodman 80K BTU 2 stage furnace and the matching Goodman air conditioner. Greg, Grant and Poitr "Peter" arrived on time, took great care, explained everything to me and they answered all of my questions. They carefully adjusted the factory settings to optimize the furnace for my house and they also checked the duct work in the basement. Dave, the Sales Manager, came by to say "hello" and to see if I was happy. YES, I am happy with the work! The furnace is very quiet. I have it running on low just to circulate the air in the house and it's so much quieter than my old furnace. When I need new duct work for an upcoming basement renovation TwinTech will be my first choice. I highly recommend TwinTech. PS. They were even nice to my dogs.
Greg was prompt on the scheduled day of installation and the work was done well within the time estimated beforehand. Installation was neat and the equipment and scope of work was as specified in the quote. One item I must point out is that we were faced with a "No Heat" situation the day before the scheduled installation and Greg came out to address it free of charge. Not only that, but he also corrected an installation fault with our smart thermostat that was not part of the original job, again free of charge.
Greg came by to do a routine furnace checkup. He was very knowledgeable and professional, letting me know what's being checked/adjusted and giving me tips to ensure everything runs smooth. Very honest and upfront about what's working fine vs. what may need to be fixed/replaced. He didn't attempt to up sell anything that wasn't necessary. I'm glad to have finally found someone I can trust and rely on for all my HVAC needs - furnace, A/C, and hot water tank.
I'm very happy with the work that was done. Everyone from salesperson to the installers were friendly and professional. They were on time and cleaned up the job site after it was installed. They also answered all my follow up questions promptly. I wouldn't hesitate to work with them or recommend them again.
Thanks to the team at Twin Tech for a great job installing my new heat pump/ac unit. The guys were very polite and professional. When they left you would never have known they had been there except for the new Mitsubishi unit on the wall!! would highly recommend the Twin Tech team.
Installed professionally, no delays, no rework needed. Very reliable contractor and sales person. Also installed BBQ gas line and some duct work.
Greg and Grant are friendly, reliable, and knowledgeable HVAC professionals. The twins, Dave and the entire team provided efficient top quality service. Our family plns to use Twintech for all of our future HVAC needs.

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!
