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 JLH from Pickering on Twintech Heating and Cooling

Imagine, it's 5 minutes after the midnight countdown New Year's eve and the furnace quits. We called TwinTech fully expecting to leave a message and actually spoke with Greg, one of the owners! We had an immediate repair early the next morning & a new furnace within the week. We have entrusted TwinTech with all our home HVAC service needs for over 6 years. That's why this week with an opportunity to purchase a new BBQ, we called them 1st to see about a gas line install. It's chicken on the grill tonight! They are efficient, reliable, honest, hard working, and -- attentive is an understatement.

by Curtis, Ajax on Twintech Heating and Cooling

Wonderful customer service, starting from the job quote (Dave), to the clean install, to the follow-up. Twintech is a small company which installed my Napoleon furnace, A/C, John Wood tank, and ran the line for my gas dryer. The installation was completed as promised in one day. The work area was kept very clean, and they even took care of my old rental tank. The professionalism and wonderful customer service is second to none. They completed all of my rebate paperwork, and now I'm getting $2000 back! You will not be disappointed if you hire this company for your project.

by Roy in Pickering on Twintech Heating and Cooling

I was referred to Twintech by a neighbour and was not disappointed. Not only was the customer service excellent their workmanship was second to none. Greg and Grant work extremely clean covering the pathway to the furnace room, labeling the essential parts, left the area spotless and were efficient. They cleaned up the mess left by the previous installers (wiring, improperly installed AC coil, and gaps in venting etc). They also ran through the operation of the new furnace and gave me some maintenance tips. Greg and Grant are professional and all around good guys. I will definitely recommend their service to anyone without hesitation.

by Peter Buck, Pickering on Twintech Heating and Cooling

Very satisfied with service from Twintech , beginning with all the information provided by Dave , which helped make the decision much easier . Installation was very smooth & done on time as promised & cleanup was well done . Would definitely recommend this company & use them again for any future needs . Well done.

by Angela from Ajax on Twintech Heating and Cooling

Twintech Heating & Cooling Inc. came in and replaced my 39 year old furnace with a beautiful Napoleon variable high efficiency furnace! Their work was efficient and professional and they were a pleasure to deal with, from sales to installation! I would highly recommend them.

by Scott and Sandra in Ajax on Twintech Heating and Cooling

After receiving numerous quotes to replace my old furnace and AC unit (which was 20 years old) I went with Twintech. Dave, in sales, answered questions professionally and promptly and worked diligently in order to secure my business. Installation was scheduled the week after and Greg and Peter showed up, as scheduled, and did a fine job installing both units. The site was left tidy and neat. I would highly recommend Twintech for your furnace and AC work.

by Linda from Whitby on Twintech Heating and Cooling

I chose TwinTech because they installed my new furnace a few years ago and did a great job. When they installed my new A/C, they replaced all parts -- the copper pipes, the housing on top of the furnace and the wiring. (Apparently, the wiring for my old A/C was insufficient.) Their pricing was competitive. The sales representative came to see me within a few hours of my call. My new A/C was installed a few days later and I couldn't be happier with Twintech's professionalism and work. I would recommend TwinTech to any homeowner.

by george polychronis from Whitby on Twintech Heating and Cooling

Had a great experience with this company. Great price and great customer service. You wont be disappointed with twintech. Discussed the job with Greg while he was installing who was extremely informative and obviously enjoys the work he does.

by Nuzio in Markham on Twintech Heating and Cooling

I needed my AC unit relocated due to upcoming landscape work. I reached out to the Twintech team through Homestars. Dave connected with me immediately to discuss the project and various options. We decided the best option was to mount the unit on the wall. Greg was in touch with me the same day as well and we scheduled the work for later that same week. This was a small job so I did not think I would get immediate attention. The Twintech team exceeded my expectations in every respect. They were very knowledgeable and friendly. The team arrived exactly on time on the scheduled day and worked efficiently to get the job done quickly. I would definitely use Twintech again for any Heating and AC projects.

by Leslie B, Pickering on Twintech Heating and Cooling

I have used Greg Dainty for over 15 years in 3 different homes, for heating, cooling, pool heaters, appliances and bbq lines. Greg has always been so professional, friendly and the workmanship nothing short of fantastic. Greg has always discussed my options and fixing versus replacing, giving his honest opinion and what works best for me cost effective wise and long term. I have valued his opinion so much and have not trusted my gas needs with anyone since using him. I have also referred him to many of my friends and family and have always been so thankful with how well and quickly he looks after us all. I hold Greg in the highest regard and would recommend him to anyone with complete confidence!

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.

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!
