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.

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

Fantastic team. Completed the job as per the specifications and in under 3 hours. Highly recommended Twintech.

During the summer, I previously hired TwinTech to replace my air conditioner when it failed. They did an excellent job so when I decided to proactively replace the furnace I contacted them. The furnace I had was 22 years old and showed signs of internal leakage. It still worked but rather than wait to have it fail in cold weather, I decided to purchase a higher efficiency model before it failed and take advantage of energy efficiency rebates. TwinTech offered very useful advice on the make and model of furnace to choose including high efficiency and variable speed motor. The price was reasonable, TwinTech arrived at the allotted time, installed the new furnace (including some re-routing of exhaust lines since the existing ones were too close to other vents), removed the old furnace, tested the installation and cleaned everything up. Overall, it was a good experience, they did a great job and the new furnace is working well.

Greg came over at 9:30pm to rescue my daughter and I from a horrible experience with Enercare that evening. He was professional. Kind. And got us what we needed quickly and at an afford price. I would 100% recommend calling on Greg and his team for any of your heating and cooling needs in the future!!

Installed a great hot water heater when our old one failed. When my furnace died during cold weather they showed up quickly and my house was warm before my wife got home. :)

I dont usually right reviews but when you receive service like this I felt it was a must. Honest and fair. I Have 4 children and on Xmas eve my furnace stopped working and a gentleman came out and got me up and running so at least we would have heat for the holidays. As promised he would replace my furnace early in the new year. The job was completed on time, great price for quality furnace and extremely clean and professional job. Would have never known anyone was in the house. Not a spec of dust or mess from lugging out an old rusty furnace. If you have any ac or heating concerns twintech is your only option. I was royally impressed with and Im sure you will be too.

This Company is terrific. No high pressure sales and they deliver exactly what they promise to deliver. The new furnace is great and we now get consistent temperatures throughout the house. The installers were great and very efficient and completed the work on schedule on the promised day. Everyone representing this company was very aware of their presence in our house and worked diligently to keep our home as uninterrupted and as clean as was humanly possible. We did not need to go around the house to clean up after they left, what a nice surprise. We have had follow up by the company to ensure everything is to our satisfaction. How unusual in today's environment. The impression left by Twintech is that they care about us and our home. This is so refreshing in today's high tech world. Out thanks go out to Dave in sales and G, G, and P (the installers).

Dec 23, 2018
The entire process was prompt and professional, from the initial quote to the installation of the new furnace. The team installed the new furnace and removed the old one in approx. 4 hrs. The guys were very knowledgeable and gave me lots of information. I have used Twintech before for a new A/C installation and new I was in good hands.

The overall experience dealing with this company was great from start to finish when getting a new furnace and ac this year. Everything was clearly explained to us during our consultation with Dave and there were no surprises with added costs. The work was done as expected and their response time to inquiries were very timely generally within a few hours or less. They are all very professional and was a pleasure to do business with them. Highly recommend to anyone looking for honest quality professional service.
