November General HVAC Checklist
Posted On: November 3, 2025
November brings cooler temperatures and more time spent indoors, making your HVAC system essential for home comfort.
Before winter weather fully settles in, it’s smart to ensure your heating equipment is running safely and efficiently.
A little maintenance now can prevent costly repairs, improve energy efficiency, and keep your home cozy all season long.
Use this November HVAC checklist to make sure your system is ready for winter.
✅ 1.
Replace or Clean Your Air Filters
Dirty filters force your HVAC system to work harder, reducing airflow and efficiency.
For most homes, filters should be cleaned or replaced every 1–3 months.
Fresh filters keep the air cleaner and your system healthier.
✅ 2.
Check Thermostat Settings
Set your thermostat to a comfortable heating schedule for the colder months.
If you don’t already have one, consider upgrading to a smart thermostat to help manage energy use automatically.
✅ 3.
Clear Vents and Registers
Blocked vents can restrict airflow and create uneven temperatures.
Move furniture and rugs away from registers so warm air can circulate freely throughout your home.
✅ 4.
Inspect Outdoor HVAC Equipment
Make sure your heat pump or outdoor unit remains clear of leaves, snow, and debris.
Keep at least two feet of clearance around the unit to help it operate efficiently.
✅ 5.
Test Your Heating System
Turn your heating on before temperatures drop too low.
If you notice unusual noises, weak airflow, or cold spots, it’s time to schedule service.
✅ 6.
Seal Air Leaks
Check windows, doors, and attic access points for drafts.
Sealing air leaks can significantly reduce heating costs and keep warm air indoors where it belongs.
✅ 7.
Schedule Professional HVAC Maintenance
A professional inspection can catch small issues before they become major repairs.
The trained technicians at Twintech Heating & Cooling ensure your heating system, furnace, or heat pump is running safely, efficiently, and reliably.

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!

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!

Amazing experience with TwinTech Heating & Cooling! Their team was professional, knowledgeable, and efficient from start to finish. They installed my new furnace quickly and left everything spotless. The technicians took the time to explain everything and made sure I was comfortable with the system before they left. Great customer service and fair pricing. I highly recommend them for anyone needing HVAC services!

I returned from vacation to find my AC unit on the Fritz. After calling way too many places I connected with TwinTech. Ive used the company in the past for my furnace so I was happy when I recognized Greg at my front door. Hes great and the service is always top notch. Id highly recommend using twintech for honest, superior service in the Durham region. Thanks!

I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!
