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.

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.

I have used Twintech many times over the years. They always arrive quickly and get the issue fixed. The most recent incident was when my air conditioner broke last week I called Greg at 11:30am and he was at my home by 2:30pm he had the unit fixed by 3:30pm. Twintech are very reliable and honest and they are experts in the field. I have already recommended them to many of my friends. I would not use anyone but them for my heating and air conditioning issues.

I would highly recommend these guys, professional, fast and competitive pricing. I moved into this place with no working AC unit with a 8 month baby, he was able to come with in a week to fix even in the busy summer days. He really values his customers , I am already recommending to my neighbors.

Very impressed they arrive to quote even though I had forgotten to call them back to confirm date & time. They showed the day before installation to deliver the unit. Returned the next day as promised at 9am. Project was completed in a professional manner. They even fixed a few things that they noticed were not installed correctly, or to code by previous heating & air contractors we had at our residence before. Would recommend this company to everyone!

Greg removed old oil furnace and oil tank from basement relocated new Napoleon propane furnace to allow duct work to be rerouted to a much more suitable location. Moved air conditioner to the new furnace. Dave recommended two available grants to assist with cost. They kept to their original quoted price which was substantially lower than a competitors for the same furnace and work. They completed the work as stated when stated and left the area clean and tidy. We are very pleased with the outcome.

We had Grant and Greg Dainty quote to replace our 20 yr old furnace. I have known them for years and have had other jobs done by them ( AC and Pool Htr). The price was very reasonable and the job was completed in one day.

TwinTech was the right choice. Our consultation with Dave set the tone. Professional and knowledgeable, we even received a follow-up call within hours of our install completion, wow! TwinTech arrived as scheduled to install our A/C unit. Within minutes of arrival Greg noted and explained a few out of code faults on our furnace installed by another company, problems fixed, thanks TwinTech. Greg, Grant and "Subaru" Pete were meticulous start to finish. Highly recommended!

Twintech replaced our aging +20 yrs old Furnace & AC with the variable high efficiency Napoleon Furnace matched with the Goodman AC. Sales guy ,Dave was great, gave a no pressure estimate, explained about the Government Rebate program which they took care of completely including arranging the home energy audit. On the scheduled day Greg and his team arrived on time, did a great job and completed the same day , extremely professional and courteous, cleaned up everything , tested the system, Greg took his time to explain the setup. Very impressed with the Napoleon Furnace 9600 which did a great job in maintaining a comfortable temperature last winter and now with the hot weather the Goodman AC cooled the house in much less time than the old AC unit could ever. From start to finish Twintech were great and have no hesitation in recommending them 100%.

The Twintech team did an excellent job installing our new Goodman air conditioner. They were polite and professional. Greg was knowledgeable and clearly experienced. Thank you Twintech for bringing our cooling system up to current regulations. Job well done!

Dave from TwinTech was very knowledgeable, professional and thorough in the buying process. He helped us to identify the best furnace for our home and our budget. When we needed a new filter a year later and seemed to have a problem finding the right one, I called Dave up and he delivered a filter to me the next day! The cost was on par with other retailers, but it was this unexpected personal service that really was impressive. The furnace? Works like a charm.
