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.

by DG Sellers on Twintech Heating and Cooling

Professionally done and took care to cover all entry floors to the house for the installers to remove the old furnace and install a new furnace.
I also made recommendations of the tankless water heater that we had installed and items to address. We did not know they also installed tankless water heaters.

by Bill, Pickering on Twintech Heating and Cooling

Price was not the cheapest nor the most expensive of my quotes. It's the quality of the installation that makes for a good AC system. The twins' knowledge & professionalism was evident in the small details:
Very clean work. Greg made sure that the refrigerant level & temperature were correct. They reinstall the insulation & vapor barrier around the wall. The outside electrical cords were secured to the wall. Proud to support this local company. Thank you.

by Taz on Twintech Heating and Cooling

Great team of guys came to do the work. Very professional. Arrived on time worked very efficiently and were very clean. They answered any questions we had without hesitation. The air conditioner works great and is so quiet. I highly recommend them and they don't try to up-sell anything right from the start.

by Jordan on Twintech Heating and Cooling

The service was prompt, professional and very courteous. Competitive price. Would highly recommend this company.

by David on Twintech Heating and Cooling

Excellent workmanship, and quick response. Would recommend Twintech to anyone.

by Todd Whyte on Twintech Heating and Cooling

My existing 15-yr old A/C went down on me during the first major heatwave of the season. Researched my options, as well as a few different installers, and decided on Twintech.

They gave me confidence right from the beginning. Extremely knowledgeable. Their communication was excellent - always responded to questions quickly. Given we were in a heatwave, they were fully booked. However, within days they were able to fit me in due to a cancellation. Upon learning that the Amana unit I was getting installed was on backorder, TwinTech went to bat for me with the manufacturer and was able to get me the next model up within a day, for the same price - Amazing!

As far as the installation was concerned, I couldn’t be more impressed. These guys were clearly very experienced and did a fantastic job. Very clean, polite, timely & informative. They even thoroughly sealed all the exposed gaps in my ductwork. I’ve had plenty of heating and cooling work done in the past and have never used the same contractor twice because I’ve never been very impressed. However, from now on, I’ll always be contacting Twintech first!

by Jordan Arnott, Courtice on Twintech Heating and Cooling

They were very friendly and took care of everything. The install looks great (and works great), they were very knowledgeable. Installed our a/c efficiently despite the difficult install location both inside and outside and they made it work.

by Lori Ellis on Twintech Heating and Cooling

Phenomenal service, so glad I found these guys a few years back after being "hosed" badly by 3 other companies. I've recommended them to so many, and they all are so thankful.

by Jonathan Rogoza on Twintech Heating and Cooling

This company is fantastic. Dave came out and gave me a very honest and reasonable quote, unlike a quote received from another company. I had a bunch of questions that were easily answered and when I had questions regarding heating/cooling a previously unheated room above the Garage, Dave arranged for Greg to come out for an assessment of this new space and gave me his recommendation along with his professional thoughts on all of my options.

These guys have been nothing but Professional, honest and helpful along the way. I can't recall the two other guys doing the install, but they were great as well. Good workmanship, everything was cleaned up and everything functions as promised. I could go on and on about my experience, but it's all positive so what more could you want?

Give them a call, see for yourself. If I had to buy another furnace/AC or heat pump, they'd be my first call.

by Private User on Twintech Heating and Cooling

I hired twin tech to convert my townhouse heating from electric to gas and install a furnace and a/c unit. I had talked with many other vendors, and received several quotes, but chose them, and very happy I did. Here are some of the reasons why:
1. They were realistic about the timeline for the work, when they could start and how long it would take. (They said upfront, it was their busy season and would need to get back to me in 3 weeks, which they did):
2. They had a quote with options for me. They were clear about the entertainment of what they would and would not do (they’d build duct work, id need another contractor to box in ductwork). This allowed me to plan as I was my own general contractor for my renovations).
3. They spoke to me in a language I understood, neither too technical nor too simple. They answered all my questions as I had them. Everyone is so lovely to work with, the sales team and the contractors who are worked in my home.
4. It’s been 4 m since the work was complete. They still answer my emails and my furnace is working very well!

I unabashedly recommend! Price, customer care and quality workmanship were all amazing!

by Aaron on Twintech Heating and Cooling

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.

by Linda on Twintech Heating and Cooling

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!

by Robert Rogers on Twintech Heating and Cooling

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.

by Robert Mizuno on Twintech Heating and Cooling

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!

by Ruth on Twintech Heating and Cooling

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!
