Do the fall checklist in this order: heating and safety checks first, then the entry, the bedroom and the windows, and the kitchen last, just before holiday cooking. Most of it is small work. Fuel-burning equipment, chimneys and gas appliances belong to a licensed professional, not a cleaning cloth.
Product and appliance instructions differ. Your owner's manual and the product label override this page, and every agency or manufacturer statement in the post links to the page it came from.

Fall is the last easy stretch before the heat runs every day and the windows stay shut. The jobs below are ranked by how much they matter, and each one links to the agency or manufacturer page it came from.
What are the most important fall cleaning jobs?
In order of importance, which is our own ranking:
- The furnace filter. Check it monthly and book the yearly heating check-up.
- Smoke and carbon monoxide alarms. Test them now, before the house is sealed for winter.
- The dryer vent. Lint is a fire risk, not just a nuisance.
- Humidity. A reading between 30 and 50 percent, and a clean humidifier if you use one.
- The entry. Mats and a boot tray before the first snow and road salt.
- Bedding, window tracks and the kitchen. Smaller jobs for early November, ahead of holiday cooking.
The first three are worth doing this week. The rest can wait until early November, before Thanksgiving on November 26.
What should you do about the furnace?
Check the filter every month. ENERGY STAR says to inspect, clean, or change air filters once a month, and to clean reusable filters and replace disposable ones. Your filter's packaging and your furnace manual set the right interval for your system.
Then book the yearly check-up. The Consumer Product Safety Commission (CPSC) recommends a yearly professional inspection of all fuel-burning home heating systems, including furnaces, boilers, fireplaces, wood stoves, water heaters, chimneys, flues and vents. That is licensed-professional work, and a cleaning visit does not replace it. ENERGY STAR adds that dirt and neglect are the top causes of heating and cooling system failure and inefficiency.
Which safety checks belong on a fall list?
They are not cleaning jobs, but they matter most in a house that is sealed for winter. CPSC's guidance:
- Carbon monoxide alarms: installed on each level of the home and outside sleeping areas, with batteries replaced annually and the alarms tested monthly
- Smoke alarms: test them once a month
- Space heaters: at least three feet away from anything that can burn, plugged directly into a wall outlet and never into an extension cord or power strip, and never left on while sleeping
- Fireplaces: fireplaces can cause fires if the chimney is cracked, blocked or coated with creosote, which is why the yearly inspection includes the chimney
Does the dryer vent need attention before winter?
Yes, and it is a fire-safety job. The National Fire Protection Association (NFPA) says to clean the lint filter before or after each load, and that once a year, or more often if clothes take longer than normal to dry, lint should be cleaned out of the vent pipe, or a dryer lint removal service should do it. It also says to check that the outdoor vent flap is not covered by snow, and that the leading cause of home clothes dryer fires is failure to clean them. The U.S. Fire Administration adds to clean the back of the dryer where lint can build up. Repairs or replacement of venting are for a qualified professional. The dryer is outside what Happy Maids cleans, per our FAQ.
What should the humidity be once the house is closed up?
Between 30 and 50 percent. CPSC recommends maintaining relative humidity between 30% and 50% if possible, says levels above 60% may allow moisture to build up indoors and condense on surfaces, and notes that a hygrometer, available at a hardware store, measures it. University of Missouri Extension gives the same 30 to 50 percent. If you see condensation on windows, Andersen Windows says it forms inside the window because the humidity level is too high indoors, and suggests running the kitchen exhaust fan when you cook and the bathroom fan until the mirror is clear.
If you use a humidifier, keep it clean. CPSC staff advise changing the water daily if possible, emptying the tank before you fill it, using distilled or demineralized water rather than tap water, and cleaning it well and often during the heating season with the unit unplugged first. A humidifier that sat in a closet since spring needs a cleaning before use, since CPSC says to clean it after summer storage.
How do you get the entry ready for salt and slush?
Start with mats. University of Georgia Extension says around 30% to 40% of the contaminants inside your home are brought in from outdoors, and recommends a highly absorbent doormat just inside the door and removing your shoes at the door. Our suggestion is to set out the mats and a boot tray before the first snow.
Road salt is the winter problem for floors. Bona, a hardwood-floor care manufacturer, says that when more grit or even road salt can be tracked indoors, deep cleaning is recommended about every two weeks. It also says vinegar and water is not recommended for hardwood floors. Your own floor's manufacturer has the final word.
What changes in the bedroom for the colder months?
For people with a dust mite allergy, Nationwide Children's Hospital says to wash sheets, blankets and other linens in hot water weekly, with water at least 130 degrees F to kill the dust mites. It adds that dust mites thrive when humidity is over 50%, which ties this job to the humidity reading above, and that you should vacuum the bedroom floor at least once a week. Items that cannot be washed can go in a plastic bag in the freezer for 24 hours, and the care label on anything you wash comes first. Our guide to what kills dust mites goes further.
Happy Maids can change bed linens as an add-on, charged per bed and requested at least one business day ahead. Making a bed is part of the cleaning and carries no charge. Washing and folding the linens is not part of our service, so the laundry stays with you.
Should you clean the window tracks before the windows stay shut?
It is a short job, and it is easier before the windows are closed for the season, which is our suggestion rather than a rule. Marvin's care guidance lists as routine upkeep to clean sand, dirt or dust from door and window hinges, sills and tracks. It says not to use cleaners containing abrasives or solvents, and to wipe any remaining traces of cleaning solution from the glass and other parts of the window and frame. Other manufacturers' instructions differ, so check yours.
On our side, interior windows within reach of a step ladder are an add-on, arranged ahead of the visit and priced separately, with at least one business day of notice. Exterior windows are not part of our service.
What about the pumpkins on the porch?
They do not last long, so carve close to Halloween. University of Illinois Extension says a carved pumpkin will last seven to 10 days depending on weather conditions. To slow the decay, it says to coat the inside of the pumpkin and the cuts with petroleum jelly, to wash the pumpkin with warm water and let it dry before carving or display, and to keep it in a cool place. It also says to avoid using candles, because the heat cooks the flesh and shortens the pumpkin's life.
What should you do in the kitchen before holiday cooking?
The oven is the biggest job and has its own timeline in our guide to cleaning the oven before Thanksgiving. Inside the oven, inside the refrigerator and inside cabinets (emptied first) are extras with Happy Maids. Our FAQ says to ask at least one business day ahead and that extras cannot be added on the cleaning day itself. For the whole house, see what to clean before holiday guests arrive.
What does a Happy Maids visit cover in the fall?
A visit follows our room-by-room cleaning checklist, with floors vacuumed with sealed-HEPA machines and mopped. If the house has not had a full reset in a while, our deep cleaning is the usual starting point and our house cleaning service keeps it going. We have cleaned homes in Barrington and the surrounding towns since 1985. Call or text 847-382-0082, or use the free estimate tool.
Dust is the other thing a closed-up house collects. Our guide to air purifiers and dust explains what a purifier does and what removes settled dust.
Where did these instructions come from?
Every statement above that is not about Happy Maids comes from the organization's own page, which we opened and read before using it:
- ENERGY STAR: maintenance checklist, clean heating and cooling
- U.S. Consumer Product Safety Commission: home heating equipment, CO alarms, 2023 winter heating release, 2020 winter safety release, dirty humidifiers
- Fire safety: NFPA clothes dryer safety tip sheet, U.S. Fire Administration clothes dryer fire safety flyer
- Universities: University of Missouri Extension, University of Georgia Extension, University of Illinois Extension, Nationwide Children's Hospital
- Manufacturers: Andersen Windows, Marvin, Bona
- Happy Maids: FAQs and policies
Agencies and manufacturers update their pages and every home is different, so your owner's manual and product labels are the final word.
Frequently asked questions
When should you do fall cleaning in Illinois?
Late October through mid-November works well, and that timing is our suggestion. The one sourced anchor is the heating system: ENERGY STAR says contractors are busy in winter and that the heating system is best checked in the fall. Do the filter, alarm and heater checks first, then the entry, bedding and windows, and the kitchen the week before Thanksgiving.
How often should you change the furnace filter?
ENERGY STAR says to inspect, clean, or change air filters once a month in a furnace, central air conditioner or heat pump, and to clean a reusable filter or replace a disposable one. Your filter's packaging and your furnace manual set the actual interval for its type and size.
What should indoor humidity be in winter?
CPSC recommends between 30% and 50% if possible, and warns that levels above 60% may allow moisture to build up and condense on surfaces. Andersen Windows says that to avoid condensation on windows, in the winter months you should aim for 30 to 35 percent humidity. A hygrometer will tell you where your house is.
How often should bedding be washed in the colder months?
For people with a dust mite allergy, Nationwide Children's Hospital says to wash sheets, blankets and other linens in hot water weekly, with water at least 130 degrees F. Follow the care label on each item, and the same page suggests a freezer bag for 24 hours for anything that cannot be washed.
Do you need to clean the dryer vent before winter?
NFPA says to clean lint out of the vent pipe once a year, or more often if clothes take longer than normal to dry, or have a dryer lint removal service do it, and to check that the outdoor flap is not covered by snow. Gas dryers should be inspected by a qualified professional. Happy Maids does not clean inside dryers or do laundry.
Where should carbon monoxide alarms go?
CPSC says CO alarms should be installed on each level of the home and outside sleeping areas, with the alarms tested monthly and the batteries replaced annually. CPSC also recommends a yearly professional inspection of fuel-burning heating systems, including chimneys, flues and vents.
Can Happy Maids clean inside the oven and refrigerator before the holidays?
Yes, as extras. Our FAQ page lists inside the oven, inside the refrigerator and inside cabinets (emptied first) among the extras, which are arranged ahead of the visit and priced separately. Ask at least one business day ahead, because extras cannot be added on the cleaning day itself.
