When the cold weather rolls into Columbus, most of us seal up our homes to keep the warmth inside. But while shutting windows and doors helps your house stay cozy, it also keeps indoor air from circulating the way it does during other parts of the year. Over time, that stale air can feel heavy, dry, or just not as fresh as you’d like it to be.
That’s why it’s good to take steps that improve indoor air quality during winter. Simple habit changes and routine checkups can make a big difference, especially when the furnace or heat pump is running every day. Winter air may be bleak outside, but inside your home, it doesn’t need to feel that way.
Breathe Easier by Controlling Humidity
Dry air is a common problem once the temperatures drop. Cold Ohio winters tend to pull the moisture out of the air, and running your heat day and night makes it worse. You might notice it through cracked lips, static shocks, or dry skin. But it’s not just about comfort, dry air can also stir up dust more easily, making your home feel less clean.
One effective way to balance this out is with a whole-home humidifier that works directly with your HVAC system. Aire-Flo Heating, Cooling & Generators installs whole-home humidifiers that integrate with your heating equipment for consistent coverage. It’s not the same as a small room humidifier you plug in and fill with distilled water. These systems help add moisture across your entire home and maintain healthier levels without you needing to adjust them often.
Getting indoor humidity back into a comfortable range helps in more ways than one. For example:
• It makes the air feel warmer, so you stay more comfortable without cranking the heat.
• It helps reduce airborne dust and allergens that dry air tends to kick up.
• It cuts back on static electricity flicking through blankets, socks, and doorknobs.
When humidity is steady, every room feels more livable, even on those icy mornings when stepping outside your front door feels like a shock.
Change Filters and Clear Your Vents
Filters are easy to overlook. They don’t make noise, they don’t flash a warning, and they’re usually tucked out of sight. But when they’re clogged, your system has to work much harder to push warm air through. And if dust, hair, or pollen has built up, all of that gets blown right back into your living space.
We always recommend checking your HVAC filters every month during heavy heating use and replacing them at least every three months. Some homes in Columbus, Dublin, and Delaware, especially those with pets or older systems, may need filter changes more often in the winter.
Don’t forget the vents either. They fill with dust and debris year-round, and during the heating season, they carry warm air through every room in your home. If furniture or rugs block them, airflow gets disrupted. If the grates are dusty, that stuff can get stirred up every time the furnace kicks on.
Here are a few things to check:
• Are your floor or wall vents open and unblocked?
• When you look at your vents, do they look dusty or dirty?
• Have you vacuumed around supply and return vents in the past month?
Little fixes like opening up airflow paths and popping in a clean filter can go a long way toward a fresher-feeling home.
Use Proper Ventilation for Fresh Indoor Air
During cold months, homes in Central Ohio often stay shut tight. It’s warm inside, and no one wants to crack a window when it’s 30 degrees outside. But this traps stale air, especially odors from cooking, pets, or strong cleaning products. Without some form of ventilation, those smells and particles stick around much longer than you’d like.
That’s when mechanical ventilation becomes helpful. These systems can bring in filtered outdoor air while pushing old air back out. They keep things moving without letting all that cold winter air spill indoors. Energy recovery ventilators (or ERVs) are a good example. They move air while holding onto the heat, so you don’t lose all the warmth you’ve built up inside.
If your home feels stuffy and the air just doesn’t feel fresh, it might have less to do with your heating system and more to do with a lack of proper ventilation. A few signs you may need better airflow include:
• Lingering smells that hang around for hours or days after cooking
• Foggy windows or a damp feeling in bathrooms
• Air that feels heavy or stale, especially in closed-off rooms
Fresh air makes a space feel cleaner, lighter, and more comfortable, even when it’s too cold to let in a breeze the old-fashioned way.
Keep Your HVAC System Clean and Checked
Like any piece of equipment, your heating system runs better when it’s clean. Dust, pet hair, pollen, and mold can settle into the parts you don’t see, the ducts, coils, and internal components. Over time, these materials can circulate throughout your home every time air moves through the system.
Scheduling a seasonal check helps avoid that. During an indoor air quality visit, our team can inspect ducts, coils, and filters and recommend equipment upgrades when needed, including air cleaners, humidifiers, ventilators, or UV lamps that work with your existing system. When your HVAC is inspected before or during the heating season, dirty parts can get cleaned out early, keeping contaminants from building up and blowing through your vents.
There’s a hidden benefit, too. When airflow is blocked by dirty parts or filters, your system has to work harder. That can create uneven heat, loud noises, or even cause a malfunction. Clean, well-maintained systems filter air more efficiently and make sure each room in your home gets the same steady warmth.
If you’ve noticed musty smells, a drop in airflow, or more dust than usual since turning on the heat, it may be time to have the system cleaned and inspected. Professional technicians can spot early signs of trouble and help keep your heat running smoothly all the way through spring.
