How to Keep Your HVAC Energy Bills Lower This Winter

Winter heating costs can add up fast—especially during long cold spells.


The good news? A few smart HVAC choices and small home adjustments can make a noticeable difference on your monthly energy bills.


At Twintech Heating & Cooling, we help homeowners stay comfortable without overpaying for heat.


Here’s how to keep your HVAC energy bills lower this winter.


Set Your Thermostat Strategically


Thermostat settings play a huge role in heating costs.


Money-saving tips:


Keep your thermostat around 68°F while home


Lower it 5–10 degrees at night or when away


Avoid frequent manual temperature changes


Use a programmable or smart thermostat for consistency


Every degree higher than necessary increases energy use and wear on your system.


Change Air Filters More Often in Winter


Your HVAC system runs more in winter, which means filters clog faster.


Dirty filters:


Restrict airflow


Force your system to work harder


Increase energy consumption


Tip: Replace filters every 30–60 days during heavy winter use.


Schedule a Winter HVAC Tune-Up


A professional tune-up improves efficiency and prevents costly breakdowns.


During a winter maintenance visit, a technician will:


Clean critical components


Check airflow and system performance


Inspect safety controls


Ensure proper combustion or heat transfer


Well-maintained systems run cleaner, quieter, and cheaper.


Seal Air Leaks and Improve Insulation


Your HVAC system can’t keep up if warm air is escaping.


Focus on:


Sealing gaps around doors and windows


Adding weather stripping


Insulating attics and crawl spaces


Closing unused fireplace dampers


Stopping heat loss reduces how long your system needs to run.


Use Ceiling Fans the Right Way


Ceiling fans aren’t just for summer.


In winter:


Set fans to rotate clockwise


Use the lowest speed setting


This pushes warm air trapped near the ceiling back down into living spaces, reducing heating demand.


Don’t Block Vents or Returns


Blocked airflow wastes energy and creates uneven heating.


Make sure:


Furniture isn’t covering vents


Rugs aren’t blocking floor registers


Return air grilles stay clear


Balanced airflow helps your HVAC system heat your home more efficiently.


Consider Upgrading to a High-Efficiency System


If your system is older, efficiency upgrades can significantly reduce heating costs.


Options include:


High-efficiency furnaces


Cold-climate heat pumps


Dual-fuel heating systems


Smart thermostats


Modern HVAC systems can cut energy usage while improving comfort.


Know When High Bills Signal a Bigger Problem


If your heating bill suddenly spikes, it may be a warning sign:


Aging or failing equipment


Improper system sizing


Duct leaks


Poor installation


An HVAC inspection can uncover hidden issues costing you money every month.


Let Twintech Help You Save This Winter


Lower energy bills start with the right system, proper maintenance, and expert guidance.


Twintech Heating & Cooling helps homeowners reduce heating costs while staying warm all winter long.

Very pleased with the installation of our new furnace and A/C unit. From quotation stage to the completion of the job Twintech was very professional.
Thank you for a job well done.

by Darren, Pickering on Twintech Heating and Cooling

My old water heater quit on me. I called TwinTech. In less than 4 days, I had my new water heater installed and the old one taken away. The whole process was quick, easy, pleasant, and well done. This is the third time I've dealt with TwinTech and I've been satisfied each time.

by Private User on Twintech Heating and Cooling

I had them replace my furnace last year. When it came time for the air conditioner this year, I did not hesitate to call Twintech again. I will also have them perform regular maintenance on them.

by Robert, Ajax on Twintech Heating and Cooling

We required a new HVAC replacement after running the old
system for 18 years.
Dave understood our requirements and gave us a quote that
covered all the necessary items.
Installation was fast and very tidy. Everything works as
it should. Our thanks to Greg, Mitch and others for their
excellent work. Recommend this family owned business to
anyone else, considering HVAC or other work.

by John Armstrong, Pickering on Twintech Heating and Cooling

I needed a new furnace and A/C to replace my 21 yr. old units, and went to the internet to view potential companies in May, I received 3 quotes,
and chose Twintech based on their salesman Dave who was very detailed and covered off everything on what Twintech was all about,
an extremely dedicated company with so many years of experience, and after reading the on line reviews I was sold on Twintech, who did not disappoint as the installation team were top notch with Greg leading,
I would highly recommend this company without any doubts, in my books they are first class all the way. Our new Amana furnace and A/C are working perfectly !

by Private User on Twintech Heating and Cooling

Flawless transaction. They did exactly what they promised, showed-up on time, cleaned-up, and were highly professional. Highly recommended.

by Bill Edmondson on Twintech Heating and Cooling

Salesperson and 2 man installation team were all professional and
knew their stuff. All three were friendly and helpful, answering all
my questions. The quality of their work demonstrated their experience
and expertise in their field.

A dear late cousin of mine recommended this company and I have been happy with the service.

by Private User on Twintech Heating and Cooling

We are very pleased with the work done by Twintech. They were very professional from start to finish. Dave came to our home and gave us a very competitive quote for new high efficiency furnace and air conditioner. The installers were very courteous and professional. We would highly recommend them.

Great experience getting an old furnace replaced.

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!
