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.

On one of the coldest days of winter, our furnace stopped working. Our regular furnace company came and told us we had a CO2 leak and shut us off. Their quote for a new furnace was way too high and they couldn't even install it on the same day. TwinTech was recommended to us by a friend. We called and spoke to Dave who was very nice and knowledgeable. Grant showed up a short time later and a new furnace was installed the same day with no troubles at all. Best of all, we received a higher-end furnace than what was offered by our previous company and at a cheaper price. I would recommend TwinTech with no hesitation at all.

Great sales member named Dave came in told us some amazing items and how they would be priced installed an all. We couldnt believe it! The next day the ac was installed, that day one employee named Greg told us that our furnace was working way to hard and was causing us to use way too much gas. So two days later they came in an installed a new furnace!

They removed and discarded old furnace. Installed new furnace. Installed air intake pipe, that had never been installed by builder, no charge. Replaced loose hose on floor with hard pipe and rerouted it to drain, no charge. Almost 33% cheaper then quote from Enercare, which was the company we dealt with and had insurance with for 8 years. No yearly fee for cleaning/insurance, saves 300 a year. Courteous, professional, fast, and friendly. My wife and I have been recommending them to everyone we know and meet, and will continue to do so. Thanks for everything, Twintech!!!

Finally! An honest company with highly knowledgeable and informative staff. Had a furnace service and found multiply errors in our system from an amateur installer. Very fair price to correct problems and will definitely use again.
