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.

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!
