What You Don’t See Can Affect You When It Comes To Winter Air Quality

When winter settles in, most of us do the same thing: shut the windows, seal the drafts, and crank the heat. It’s great for comfort and energy efficiency, but not always great for the air we breathe. With homes closed up tight for months at a time, indoor air quality can quietly take a hit, leading to discomfort and even health concerns.

The good news? A few smart habits and simple upgrades can make a noticeable difference.

Why Indoor Air Quality Suffers in Winter

Cold weather means less fresh air circulating through your home. At the same time, heating systems kick into high gear, stirring up dust and other particles that might otherwise stay settled. Common indoor pollutants during winter include dust, pet dander, mold spores, and volatile organic compounds (VOCs) released from cleaning products, paints, and furnishings.

When these pollutants build up, people may experience headaches, fatigue, sinus irritation, or respiratory issues - symptoms often lumped under the term “sick building syndrome.” If you’re feeling off all winter, your indoor air might be part of the problem.

Practical Ways to Improve Winter Air Quality

Let Fresh Air In, Yes, Even in Winter

You don’t need to leave windows wide open. Short bursts of fresh air, just a few minutes at a time, can help flush out stale indoor air. Using kitchen and bathroom exhaust fans also helps remove moisture and airborne contaminants right at the source.

Keep Humidity in the Sweet Spot

Indoor humidity should hover around 40–50%. Too much moisture encourages mold growth, while air that’s too dry can irritate your nose, throat, and skin. A humidifier or dehumidifier can help keep things balanced, especially in older homes.

Stay on Top of HVAC Maintenance

Your heating system keeps you warm and moves air throughout your home. Change filters every three months and schedule annual maintenance to keep things running efficiently. Dirty filters and neglected systems can spread dust and allergens instead of trapping them.

Use Air Purifiers Where You Spend the Most Time

A quality air purifier with a HEPA filter can significantly reduce airborne particles like dust, pollen, and pet dander. Units with activated carbon filters also help absorb odors and chemical fumes. Bedrooms and living areas are usually the best places to start.

Add a Few Low-Maintenance Houseplants

Some plants help improve indoor air quality while also making your home feel more alive during the gray winter months. Snake plants, for example, are hardy, low-maintenance, and known for their air-filtering benefits.

Choose Cleaning Products Carefully

Many conventional cleaners release VOCs that linger in indoor air. Switching to natural or low-VOC products can reduce chemical exposure. When stronger products are necessary, proper ventilation is key.

Install and Maintain Gas Detectors

Carbon monoxide and radon are invisible, odorless, and potentially dangerous. Make sure detectors are installed and functioning properly, and test them regularly, especially during heating season.

Keep Dust Under Control

Regular dusting and vacuuming go a long way. Using a vacuum with a HEPA filter prevents allergens from being kicked back into the air while you clean.

Go Easy on Scents

Candles, plug-ins, and air fresheners may smell nice, but many release VOCs. If you use them, do so sparingly and make sure rooms are well ventilated.

Breathe Easier All Winter Long

Winter doesn’t have to mean stale air and stuffy rooms. With a few proactive steps, you can protect your indoor air quality, improve comfort, and create a healthier home environment for everyone under your roof.

Unwanted Holiday Houseguests

As winter settles in, you might find yourself sharing your home with some unexpected guests. Mice, raccoons, squirrels, and even possums often look for warmer places to stay as the weather grows colder. Attics make an ideal retreat, providing shelter from the elements. If you’re hearing strange noises such as squeaks, scurrying, or even hissing, especially late at night, it’s likely that a critter has moved in.

If an animal has taken up residence, it’s important to act quickly before they get too comfortable. Once settled, they may start nesting, which can lead to further damage. Most animals leave clues that help identify them. High-pitched squeaks or chewing sounds usually mean rats or mice, while fast scurrying is often a sign of a squirrel or a mouse. Raccoons, known for their snarling and hissing, tend to make more aggressive noises. While some animals move into your attic on purpose, others may be there by accident and are simply trying to find a way back outside. Understanding what you’re dealing with can help you determine the best course of action.

Animals in your attic aren’t just a nuisance; they pose serious risks to your home. Most will gnaw on anything they encounter, especially mice and rats, which chew through wiring, creating fire hazards. Larger animals like raccoons and possums can tear apart insulation and ruin ductwork, leading to costly repairs. Their droppings and urine can also create unpleasant odors and unsanitary conditions.

If your problem is mice or rats, they likely came in looking for warmth and water. These small animals can squeeze through holes as tiny as a dime, so sealing any potential entry points and fixing leaks is essential. Setting bait traps can catch some of the rodents already inside, but long-term solutions require securing all access points to prevent re-entry.

Squirrels, on the other hand, usually prefer the outdoors and may have come into the attic by mistake. They often get in through soffits or vents. One of the best ways to help them leave is by installing an exclusion door - a one-way exit that allows them to leave but not return.

Raccoons are more determined and will stay put if they find a warm, dark spot. Since they’re nocturnal, try leaving lights on in the attic and playing music to encourage them to find somewhere quieter to rest.

Bats are trickier, as they’re usually very quiet unless there’s a large colony present. Due to potential health risks, bat removal should only be performed by a certified DEEP specialist.

Finally, possums, much like raccoons, are resilient squatters that often refuse to leave. Their droppings can quickly accumulate, leaving a huge mess and a foul odor. The best way to handle a possum is to call a professional for humane trapping and removal.

Ultimately, dealing with unwanted animal visitors is best left to professionals. Ignoring the problem can result in more than a few sleepless nights; it can lead to extensive and costly repairs.

10 Tips to Keep Your Home Warmer This Winter

When Connecticut winter settles in, temperatures drop quickly and your home’s heating system has to work overtime. The good news is that staying warm doesn’t have to mean turning the thermostat up and hoping for the best. With a few practical upgrades, many of which you can handle yourself, you can boost comfort, improve efficiency, and keep drafts at bay. Here are ten reliable ways to make your home warmer this winter.

1. Seal Up Drafts Around Doors and Windows

Even small gaps can let in a surprising amount of cold air. Check for drafts by running your hand along the edges of windows and exterior doors. If you feel air movement, use weatherstripping, caulk, or draft stoppers to seal the gaps. These fixes are simple, inexpensive, and often make an immediate difference.

2. Install Thermal Curtains or Insulated Shades

Your windows can lose up to 30% of your home’s heat, even if they’re newer. Thermal curtains or honeycomb cellular shades add an extra layer of insulation to help keep warm air in and cold air out. Close them at night and on cloudy days, then open them when the sun is shining to take advantage of natural heat.

3. Reverse Your Ceiling Fans

It sounds counterintuitive, but ceiling fans can actually help warm a room. If your fan has a reverse switch, flip it to the clockwise setting for winter. This gently pushes warm air, which loves to hang out near the ceiling, back down where you actually need it.

4. Add Area Rugs to Hard Floors

Wood, tile, and laminate floors can feel icy and pull warmth from the room. Adding thick area rugs, especially in basements or rooms over unheated spaces, helps insulate the floor and make your home feel instantly cozier.

5. Check and Replace Weatherstripping on the Attic Hatch

The attic access door is one place homeowners forget to check, but it’s a notorious escape route for heat. Make sure the hatch closes tightly and that the weatherstripping hasn’t compressed or cracked. A tight seal here helps prevent heat from rushing straight into the attic.

6. Change Your Furnace Filter Regularly

A dirty furnace filter forces your heating system to work overtime, which can make your home feel less warm and your bills noticeably higher. Check your filter monthly and replace it as needed. It’s an easy DIY task that can improve airflow and efficiency right away.

7. Insulate Hot Water Pipes

Insulating the hot water pipes in your basement or utility area helps reduce heat loss as water moves through your home. Pipe insulation sleeves are inexpensive, easy to install, and can improve both water temperature and heating efficiency.

8. Add Door Draft Blocks in Older Homes

Connecticut is full of beautiful old homes but those charming original doors often come with less charming drafts. Door draft blockers (or even a rolled-up towel in a pinch) can help keep cold air from sneaking in under exterior doors. Bonus: they’re kid-friendly DIY projects.

9. Get Your Heating System Professionally Tuned

A yearly tune-up can help your furnace run more efficiently, identify issues before they become bigger (and more expensive) problems, and ensure your system is operating safely. Plus it will lengthen the lifespan of your system.

10. Consider Small, Strategic Upgrades

If your home still feels chilly, a few targeted improvements can help. Adding attic insulation, sealing ductwork, or upgrading older thermostats to programmable or smart models can make a big difference. These projects vary in difficulty - some homeowners feel comfortable tackling them, others prefer a professional - but in many cases, the energy savings can quickly outweigh the upfront cost.

Winter in Connecticut will always bring its share of cold snaps, but with a little preparation, your home can stay warm, comfortable, and energy-efficient all season long. Whether you’re sealing a drafty window yourself or calling in a pro for a furnace check, small steps can add up to big improvements.
