Is It My Fault My Heating Costs Are Going Up?

If you’ve opened your energy bill lately and felt your stomach drop, you’re not alone. Many Ontario homeowners see heating costs rise year after year—especially after a long winter.
The question is: is it something you’re doing wrong… or is it just the way things are?
The honest answer? It’s usually a mix of both. Some factors are completely out of your control, while others come down to how your home and HVAC system are performing.
Let’s break it down.
Rising heating costs are often caused by:
But there are also hidden factors inside your home that can quietly drive your bills up—without you realizing it.
One of the biggest reasons for rising heating costs has nothing to do with you at all.
In Ontario:
Even if your usage stays the same, your bill can still go up.
This is one area where homeowners often contribute—without meaning to.
Common habits that increase costs:
Even a few extra degrees can significantly increase your heating bill over time.
Tip: Lowering your thermostat by just 1–2°C can lead to noticeable savings.
If your home isn’t well sealed or insulated, your heating system has to work much harder.
Common heat loss areas include:
This isn’t always obvious—but it can have a major impact on your energy use.
Your heating system plays a huge role in efficiency. If it’s not running properly, it may be using more energy than necessary.
Potential issues include:
Even a well-installed heat pump can lose efficiency over time without proper care.
If your system hasn’t been serviced recently, it could be working harder than it should.
Without maintenance:
This is one of the most common—and fixable—reasons for rising heating costs.
Your system depends on proper airflow to heat your home efficiently.
Issues like:
…can all force your system to run longer to achieve the same results.
Sometimes, it really does come down to the weather.
If the winter was:
…your system had to work harder, which naturally increases your bill.
Older heating systems become less efficient over time—even if they’re still working.
Signs your system may be losing efficiency:
If your system is aging, rising costs may be a sign it’s time to consider an upgrade.
While you can’t control energy prices or the weather, you can take steps to reduce your heating costs:
These small changes can make a big difference over time.
If your heating costs are going up, it’s probably not entirely your fault—but there may be opportunities to improve efficiency and lower your bills.
Most homeowners are surprised to learn how much of an impact:
…can have on their energy usage.
Rising heating costs can feel frustrating, but they’re often a combination of external factors and hidden inefficiencies inside your home.
The good news? Many of these issues are fixable.

On coldest night of the year our furnace quit. At 8:40 in the morning Greg arrived and gave us a diagnosis and a recommendation. By 2:30 we had a new furnace and were warm again. Great company. Great customer service. Good reasonable price.

Twin tech team was very efficient and prompt. They provided a quote within hours of request and got the job done on time. No disruption to home function. We would highly recommend this team. Job well done.
Our furnace bit the dust, and Twintech came out to troubleshoot and diagnose the problem within a couple of hours. Mitch was super helpful, patient, and answered all of our questions. When we decided to get the furnace replaced, the crew was over first thing the next morning and did a fantastic job. Not only did they complete the job in a few hours, but they cleaned up and respected our house as they went, and answered all of our follow-up questions. I've used Twintech for our HVAC needs in the past and will continue to do so. I'd recommend them to anyone, and it feels good to support a local, family-owned business.
Dave and the Twintech team were fabulous from day 1 and helped us through the process to identifying a new furnace and AC unit. This was our first time through this process and Dave did a thorough job explaining all the components and was very patience answering all our questions. Dave provided great insights and fair pricing.
The Twintech team did an awesome installation. Very clean and efficient. I would highly recommended their service.
We had a new Amana furnace installed by Twintech and we were very pleased with the installation. It is nice to have a warm house again.
Excellent job. Excellent service. Competitive price. Its rare to find a company with the knowledge and professional results we have experienced with Twintech. The clean and neat installation with attention to detail and drop sheers to respect our property is a clear indication of Twintechs high level of integrity. The 1-1/2 gas line upgrade they did for our pool 3 years ago was awesome. Can't say enough. Thank-you Twintech.
Twitch did a great job with the installation of our new furnace. I really appreciated their honesty and I could trust what they were telling me. Another company tried to suggest significantly more work at a greater cost claiming it was necessary to meet current building code. Twintech is very fair. All staff I meet were friendly, polite and trustworthy. I would recommend Twitch for a furnace.
This is a professional team that's easy to deal with. I would strongly recommend them
Very professional firm from start to finish!
They removed the old oil tank and furnace. They installed air conditioning and a new propane furnace.
Professional installation, on time and no mess.
Very pleased with their work and would highly recommend the company. Our house is three stories so they spent the time to do all the calculations to make sure we would have great performance on each floor.
Thank you again!
Upon a routine yearly maintenance, it was discovered there was a leak in the heat exchanger and a I needed a new furnace. I know nothing about these things and was completely stressed out. The company I had the maintenance plan with quoted me a huge number to rent a furnace, I just wanted to cry. Then I spoke to Dave at Twintech. He was so knowledgeable and calming, provided me a fair quote and within a few days I had an amazing crew show up to my house and install my new energy efficient furnace! I have already recommended these wonderful people at Twintech to a good friend of mine. Thank you Twintech!!

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!
