How to Get the Most Out of Your Heat Pump This Winter

Winter in the Durham Region and Toronto can be long, cold, and unpredictable — which makes it the perfect time to ensure your heat pump is running at peak performance.
Whether you recently installed a new system or have been using one for years, a few smart habits can dramatically improve comfort, efficiency, and savings.
Here’s how to take full advantage of your heat pump during Ontario’s winter months.
1.
Set It and Forget It — Avoid Constant Thermostat Adjustments
Heat pumps work best when they maintain a steady temperature.
Why you shouldn’t keep adjusting the thermostat:
Frequent temperature changes make the system work harder
Maintaining a steady set point is more energy-efficient
Modern heat pumps regulate power levels automatically
For most homes in Durham Region and Toronto, a temperature between 20–22°C keeps things comfortable without overworking the system.
2.
Keep Your Outdoor Unit Clear of Snow and Ice
Ontario winters mean snow, wind, and icy buildup.
A blocked outdoor unit can reduce efficiency or cause short cycles.
Check your unit regularly for:
Snow accumulation
Ice buildup
Fallen branches or debris
Gently clear around the unit with a soft brush or broom — never chip at ice.
If you notice persistent icing, Twintech can inspect it to ensure everything is functioning properly.
3.
Clean or Replace Filters Monthly
Your heat pump depends on proper airflow.
During winter, indoor air is drier and dustier, so filters can clog faster.
Clean filters mean:
Better airflow
Lower energy bills
More consistent heating
Improved indoor air quality
A quick monthly check can make a huge difference.
4.
Use the Right Heat Pump Mode
Many homeowners accidentally use the wrong settings, which can reduce comfort or increase energy use.
For winter, use: ✔ HEAT mode for primary heating ✔ AUTO-FAN mode for balanced airflow ✘ Avoid using AUTO temperature mode, which can switch to cooling unexpectedly
If you’re unsure, Twintech technicians can help optimize your settings.
5.
Don’t Rely on Backup Heat Unless Needed
Most heat pumps include auxiliary or emergency heat, but these modes use much more energy.
Use Emergency Heat only during a malfunction or extreme cold (usually below –20°C for older systems).
Modern cold-climate heat pumps used in Toronto and Durham Region rarely need backup heat during typical winter days.
6.
Improve Home Efficiency to Boost Heat Pump Performance
Your heat pump is only part of the comfort equation.
Improving your home’s overall efficiency helps your system work at its best.
Simple steps include:
Sealing drafts around windows and doors
Using thick curtains at night
Keeping interior doors open for better airflow
Adding weatherstripping in older homes
These upgrades help maintain stable indoor temperatures and reduce strain on the system.
7.
Take Advantage of Zone Heating
If your heat pump includes multiple indoor units (common with ductless systems), you can heat different areas independently.
Optimize zone heating by:
Heating the rooms you use most
Lowering temperatures in guest rooms or unused spaces
Keeping doors open to share warm air when needed
This maximizes comfort and savings.
8.
Schedule Professional Maintenance Before Peak Cold
Heat pumps run almost year-round, so they benefit from regular professional care.
A Twintech technician will:
Check refrigerant levels
Clean coils
Inspect electrical components
Test sensors and controls
Ensure your system is winter-ready
Preventive maintenance improves performance, reduces energy use, and extends your system’s lifespan.

Great service and great people to deal with, from sales to installer. I highly recommend this company.
Twintech replaced our aging furnace and air conditioner recently. I highly recommend this company. Their quote was competitive, they were on time and respectful of our home and extremely professional. From the salesman to the installers and the owner who followed up afterward to ensure we were satisfied, we are very pleased with the service. We are looking forward to working with this company for all of our HVAC needs for the years to come. Excellent workmanship and service!
We wanted to get our AC replaced as it was 22-years old and added to this our furnace was costing more and more to repair. So, we decided to get both the furnace and AC replaced.
After going through a few quotes and product reviews we decided to go with Twintech. The three-men crew arrived early in the morning, wasted no time and got to work right away. By 2:00 pm, they were all done. Ive found their work to be top notch and they were completely professional. I had all my questions answered to my satisfaction both during the progress of their work and at end.
I have pleasure in recommending Twintech to anyone who is looking to get their furnace or Ac replaced

Our air conditioner died On a Saturday and within hours Dave came out to take a look and discuss replacement/repair options.
The new air conditioner was installed on the Wednesday. The new unit was installed quickly. The installers were friendly and cleaned up afterwards.
We noticed a slight leak around the furnace that night and they came out the next day and fixed the issue. It has been working great and is quieter than our previous unit.
Very satisfied and would highly recommend TwinTech.
I contacted TwinTech to replace my 20-year old A/C. Dave, their service rep, promptly replied and was at my home within 2 hours. He was friendly and knowledgeable and didn't try to upgrade or oversell their A/C units but suggested the best fit for my small 1000 feet bungalow. Although this was during a heatwave and very busy, they were able to fit me in 2 days later. The TwinTech crew installed a 1.5 ton Ducane A/C unit that is now running smoothly while maintaining a constant cooling temperature. The crew were very courteous, professional and efficient and I will definitely recommend TwinTech to family and friends. I much appreciated your great service.

We had a great experience. The guys who installed our a/c did a nice job. Cleaned up.
excellent crew, fast and efficient! Would call them again when I need a new furnace.
Professional, courteous and efficient, dont need to say more than that! Use them you will not regret it.
TwinTech was a pleasure to deal with from the estimate through installation. We replaced a 28 year old a/c unit with one recommended by TwinTech's sales representative Dave who took the time to go over the product with us and answer any questions. The warranty is for 10 years parts and labour and they will complete the registration for you. Installation was by Greg (owner) and Mitch and Spencer who were quick and efficient and left everything clean and tidy.
Very professional, from the sales consultation and inspection to the final installation. Met every expectations we had for the job. A local business with great client support. We highly recommend. Twintech is a blue chip! Thanks!

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!
