November General HVAC Checklist

Posted On: November 3, 2025

November General HVAC Checklist

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.


Stay Warm With Twintech Heating & Cooling


Preparing your HVAC system in November sets the stage for a comfortable and stress-free winter.


Whether you need routine maintenance, repairs, or a new heat pump installation, Twintech Heating & Cooling is here to help.


Stay cozy, stay safe, and enjoy the season with expert HVAC care you can trust.

by Bill, Whitby on Twintech Heating and Cooling

Reasonable price and the workmanship was prompt and timely and the employees were great to deal with.

by Nadia, Toronto on Twintech Heating and Cooling

The sales process was friendly, informative, and very consultative. They worked hard to earn our business by taking a careful look around our home to assess our needs, providing a lot of information about the product, and answering all our questions and finding the right solution for our home at a competitive price. They prepared us very well for what to expect on installation day, and the installation went very smoothly - no surprises, all very professional! They gave us a call after installation to ensure we were happy with the work. We're very happy that we chose to work with TwinTech to get our new furnace.

by Private User on Twintech Heating and Cooling

Twintech promptly responded to request for quotation. They were thorough and helpful in explaining options. The quote was very competitive. Installation of new furnace was very professionally completed. Excellent work.

by Rita, Scarborough on Twintech Heating and Cooling

When our old oil furnace finally broke down we decided it was time to finally convert to natural gas and finally install central air conditioning at the same time. Knowing it was going to be a significant investment for us, we wanted to make the right choice. Twintech came highly recommended by a friend and we were not disappointed. From the first contact with the salesperson, until the final touches on the installation, we were so pleased with their service. Everyone from the company was so friendly, efficient and a pleasure to deal with. Best of all, the cost was very competitive. We would certainly recommend Twintech to anyone requiring HVAC work in their home.

by Bob S, Pickering on Twintech Heating and Cooling

Mitch from Twintech came out for our annual furnace inspection. We found him to be friendly, conscientious & he left the work area clean. We were also very impressed with the thoroughness of the job he did. This is the 2nd job we’ve had Twintech do for us & have been very happy with the results for each. We highly recommend this company. Thank you, Mitch, Dave & Greg.

by Brent L on Twintech Heating and Cooling

Work was done on schedule, professionally, according to quote and with minimal inconvenience to building users. Very happy with the end result. The only area for improvement from my experience - need more timely quoting process.

by Karen on Twintech Heating and Cooling

The team was great! Very knowledgeable, professional and extremely helpful. A few days after install the unit didn’t seem to be working, user error, but within minutes of contacting them..on a Saturday.. a tech was on the phone troubleshooting with us. I highly recommend Twintech for your cooling or heating needs. They stand by their products and a pleasure to deal with.

by Rob on Twintech Heating and Cooling

During the hottest week in the summer our old A/C decided to call it quits. I called Twintech Heating & Cooling after receiving a referral from a family member; came highly rated for being an honest, family-run business, who appreciates their customers. Dave was able to accommodate my hectic schedule and book a late evening appointment to walk through the specifics. Greg and Mitch arrived exactly on time a few days later, were very polite and friendly, and within a couple of hours had a new unit up and running. I also received a follow-up call to ensure we were happy with the Amana.

by Linda Robinson on Twintech Heating and Cooling

They were on time and very professional. I'm so glad I decided to go with Twintech, thanks!

by Famcam1953 on Twintech Heating and Cooling

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!
