Fall Home Safety Checklist for NJ: Furnace, Chimney & Dryer Vent
Your furnace, chimney, and dryer vent all work hardest from November to March — and they're behind many winter fire and carbon monoxide calls. Here's a simple fall checklist for New Jersey homes.
Every fall, New Jersey homes switch on three systems at once. The furnace runs for the first time in months, the fireplace gets its first fire, and the dryer works overtime on heavy winter loads. Those three — heating equipment, the chimney, and the dryer vent — are behind a large share of winter house fires and carbon monoxide calls.
The good news: most problems give warning signs, and a few minutes of checking now prevents almost all of them. Here's the checklist we give our own customers.
Why fall is the time to check
- Heating fires peak in winter. The National Fire Protection Association (NFPA) ranks heating equipment among the leading causes of U.S. home fires, with most heating fires happening in December, January, and February.
- Carbon monoxide is invisible. According to the CDC, more than 400 Americans die each year from unintentional carbon monoxide poisoning not linked to fires. Furnaces, fireplaces, and blocked flues are common sources.
- Dryer lint is fuel. The U.S. Fire Administration reports roughly 2,900 home clothes dryer fires each year, and failure to clean is the leading cause.
Your 15-minute DIY checklist
Furnace and HVAC
- Replace the HVAC filter. ENERGY STAR recommends checking it monthly during heavy use and replacing it at least every 3 months.
- Run the heat for 10–15 minutes before the first cold night. A brief burning-dust smell is normal; a smell that lingers, banging or rattling, or a yellow flame on a gas burner is not.
- Keep anything that can burn at least 3 feet away from the furnace, water heater, and space heaters.
- Make sure supply and return vents aren't blocked by furniture or rugs.
Chimney and fireplace
- From the ground (binoculars help), look for a missing cap, a cracked crown, a leaning stack, or white staining on the brick.
- Open and close the damper — it should move freely and close fully.
- With the damper open, shine a flashlight up the flue to look for nests or debris.
- Burn only seasoned hardwood that has been split and dried for 6–12 months.
- If your chimney hasn't been swept or inspected in the last 12 months, book it before the first fire.
Dryer vent
- Clean the lint screen after every load.
- Go outside while the dryer runs and confirm the exterior flap opens with strong, warm airflow.
- Replace any white vinyl or foil accordion hose behind the dryer with semi-rigid or rigid metal duct.
- Time a normal load. If it takes more than 45 minutes or two cycles, the vent is restricted. (See all 10 warning signs.)
Smoke and CO alarms
- Test every smoke and carbon monoxide alarm and replace the batteries.
- Make sure there's a CO alarm on every level of the home and outside each sleeping area.
- Replace any alarm that's past the date printed on the back.
What to leave to a pro
| System | What a pro does | How often |
|---|---|---|
| Furnace / AC | Tune-up: clean and inspect burners and blower, check venting, test safety controls | Heating every fall, cooling every spring |
| Chimney | Sweep and inspection; Level 2 camera inspection when needed | Every year |
| Dryer vent | Full-length cleaning with rotary brushes and an airflow check | Every year (every 6 months for heavy use) |
| Air ducts | Cleaning of supply and return ducts, registers, and air handler | Every 3–5 years, more often with pets or after renovation |
Book before November if you can. By then, most NJ chimney and HVAC companies are booked weeks out.
Get it all done in one visit
Most homeowners don't skip this maintenance on purpose — they just forget until something goes wrong. That's why we created the Green Care Club. For $19/month, members get their yearly furnace/AC tune-up, dryer vent cleaning, and chimney inspection scheduled for them, with reminders before every visit and priority scheduling.

Frequently Asked Questions
When should I get my furnace serviced in NJ?
Early fall — September or October — before the first cold snap. ENERGY STAR recommends checking your heating system every fall and your cooling system every spring.
Is it normal for the furnace to smell when I first turn it on?
A light burning-dust smell for the first few minutes of the season is normal. A smell that lingers, an electrical burning smell, or any rotten-egg (gas) odor is not. If you smell gas, leave the house and call your gas utility or 911 from outside.
Do I need a chimney inspection if I rarely use my fireplace?
Yes. NFPA 211 recommends an annual inspection whether or not you burn often. Unused flues are a favorite spot for birds and animals to nest, and gas fireplaces need inspection too.
How often should I clean my dryer vent?
At least once a year, and every 6 months if you do a lot of laundry, have pets, or have a long vent run or a roof termination.
Where should carbon monoxide alarms go?
Put a CO alarm on every level of your home and outside each sleeping area, follow the manufacturer's placement instructions, and test them monthly.
