How to Keep Your HVAC Energy Bills Lower This Winter
Posted On: February 2, 2026
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.

Dave was great in helping me get the proper units for my property, as well as getting them installed. The installers arrived when they said they would, and completed the project on time, and professionally. If I needed another furnace, I would use Dave again.

I have known Greg and Grant Dainty for many years and have used their company for my house and business. I recommended them also for my parents and sister and they all have been very satisfied with the quality of work for a reasonable price. I just recently had them install a new HVAC system in an older house and was very pleased with their work. Craig in Pickering. After meeting with various heating and air conditioning contractors I was referred to Twin Tech Heating and Cooling through a family member. Greg and Grant arrived at my home and provided me with an estimate and a plan as to how they were going to remove and replace my furnace and air conditioner. On the day of install Greg and Grant arrived at my home on time and were very professional and extremely courteous as to any questions or concerns that I had. The removal and install was truly professional and the attention to detail was exactly what I was looking for. Ive seen many installs from other contractors and I couldnt be any happier to have had such a clean looking install. The sheet metal work, ducting and venting all look fantastic. Upon completion Greg and Grant left me feeling extremely happy and very fortunate of a job well done. Thanks again Twin Tech!!

To whom it may concern, I recently had TwinTech (Greg and Grant Dainty) replace my furnace and service both my gas fireplaces and air conditioning unit. They were professional, courteous and very fair in their pricing. I would gladly recommend TwinTech to anyone needing work done. I can be contacted at 905-626-XXXX.

My Fiancé and I have relied on Twintech Heating and Cooling now for the better part of the last 10 years. In that time, Greg has installed a furnace, an air conditioner, and a heat-pump at our residence in Toronto. In each instance Greg and his team were a pleasure to deal with. They were courteous and professional throughout the whole process and the quality of their work is first rate. Our experiences have always been extremely positive and we have referred his services numerous times to our friends and family. Without hesitation, I would recommend Greg and TwinTech Heating and Cooling to anyone looking to service or replace their existing heat/AC equipment
