How to Improve Indoor Air Quality and Home Comfort During Winter in Ohio

When temperatures drop in Ohio, we spend more time indoors with our heating systems running. While your furnace keeps your home warm, it also plays an important role in your indoor air quality, humidity levels, and overall comfort.

How can you improve indoor air quality during winter? Maintaining proper humidity, choosing the right air filter, improving ventilation, and keeping your heating system in good condition are all important steps. These measures can help reduce indoor air quality problems, manage allergens, and create a more comfortable home for your family.

Here are five ways to help your HVAC system support a healthier, more comfortable indoor environment this winter.

1. Maintain Healthy Indoor Humidity Levels

Why is my house so dry in the winter? Cold outdoor air typically contains less moisture than warm air. When that air enters your home and is heated, the relative humidity drops, which can leave your skin feeling dry and your nose and throat irritated.

Maintaining appropriate indoor humidity can improve comfort and help reduce some of the problems associated with excessively dry air.

A whole-home humidifier works with your HVAC system to add moisture to the air throughout your house. Unlike portable humidifiers that serve individual rooms, a whole-home system can provide more consistent humidity control.

However, adding too much moisture can create another problem. Excessive indoor humidity can contribute to condensation, mold growth, and dust mite problems.

What humidity level should my house be in during winter? A relative humidity level of approximately 30% to 50% is a common indoor guideline, although the ideal setting may be lower during very cold weather to prevent condensation on windows and other cold surfaces. Monitor your home and adjust humidity based on outdoor temperatures and signs of excess moisture.

If your home feels unusually dry or you notice condensation on your windows, talk with an HVAC professional about whether a whole-home humidifier or another humidity-control solution is right for your home.

2. Find the Right Indoor Temperature for Your Home

Your thermostat setting affects more than your energy bill. It also influences how comfortable your home feels throughout the day and night.

What temperature should I keep my house at during winter? The best temperature depends on your household's preferences, activity levels, and health needs. Many households choose a comfortable daytime setting around 68°F to 70°F and lower the temperature at night if everyone remains comfortable.

A programmable or smart thermostat can automatically adjust the temperature based on your daily routine. Lowering the setting when you're asleep or away can help reduce heating costs without sacrificing comfort when you're home.

However, adjusting the thermostat won't solve every comfort problem. If one bedroom feels freezing while the living room is warm, your home may have uneven airflow, inadequate insulation, air leaks, or ductwork issues.

Before assuming your furnace needs to be replaced, have the underlying problem evaluated. Sometimes, balancing the airflow or sealing drafts can make a noticeable difference in how evenly your home heats.

3. Improve Ventilation and Reduce Indoor Air Pollutants

During winter, keeping windows and doors closed helps retain heat. Unfortunately, limited ventilation can also allow indoor pollutants and moisture to accumulate.

Cooking, showering, cleaning products, pets, and everyday household activities can all affect indoor air quality.

How can I improve ventilation in my house during winter without losing heat? Start by using bathroom exhaust fans during showers and range hoods when cooking, especially when they vent outdoors. These fans help remove excess moisture, odors, and other airborne pollutants at their source.

Opening windows briefly when weather permits can also introduce fresh air, although it may increase heating demands.

For a more continuous solution, consider a whole-home ventilation system. An energy recovery ventilator (ERV) exchanges indoor air with outdoor air while transferring heat and, under appropriate conditions, some moisture between the air streams. This helps reduce the energy penalty associated with bringing in fresh air.

An HVAC professional can evaluate your home's ventilation needs and determine whether an ERV or another ventilation solution would be beneficial.

Proper ventilation is especially important in tightly sealed homes, where fresh air may not enter naturally at sufficient rates.

4. Reduce Dust, Allergens, and Other Airborne Particles

If you notice more dust, sneezing, or allergy symptoms when spending time indoors during winter, your home's indoor air quality may be worth investigating.

Dust, pollen, pet dander, and other airborne particles can accumulate indoors. Your HVAC system's filtration is one way to capture some of these particles as air circulates through the system.

What is the best furnace filter for indoor air quality? The right filter depends on your HVAC system's design, the type of particles you want to capture, and the amount of airflow your system requires.

Here are a few ways to improve filtration and manage airborne particles:

• Replace your furnace filter regularly. Check the manufacturer's recommendations and inspect your filter periodically. A clogged filter can restrict airflow and affect system performance.
• Choose a compatible filter. Higher-efficiency filters can capture smaller particles, but your system must be able to accommodate the filter's airflow resistance. Check your equipment specifications or consult an HVAC professional before upgrading.
• Consider a whole-home air purifier. Depending on the technology, these systems can capture or otherwise reduce certain airborne particles and contaminants throughout your home.
• Keep dust under control. Regular cleaning, vacuuming with a suitable filter, and washing bedding can help reduce the accumulation of dust and allergens.

Filtration and air purification can complement good ventilation and cleaning practices, but no single product removes every indoor pollutant. If indoor air quality remains a concern, a professional assessment can help identify the most appropriate solution.

5. Eliminate Drafts and Uneven Heating

A comfortable home should feel reasonably consistent from room to room. If you have cold spots, drafty windows, or rooms that never seem to warm up, your heating system may not be distributing heat effectively.

Why is my house cold even when the furnace is running? Several issues can contribute to uneven heating, including air leaks, insufficient insulation, blocked supply vents, ductwork problems, or an improperly balanced HVAC system.

Try these steps to improve comfort:

• Seal air leaks. Weatherstripping and caulking around windows and doors can help prevent cold air from entering and warm air from escaping.
• Keep supply and return vents clear. Furniture, rugs, and curtains should not obstruct airflow.
• Check your furnace filter. A dirty filter can reduce airflow and make it harder for your system to distribute heat.
• Investigate uneven airflow. If some rooms consistently receive less warm air, your ductwork or system balance may need attention.
• Schedule professional heating maintenance. A technician can inspect your system, evaluate its operation, and identify issues that may affect comfort and performance.

Replacing your furnace is not always the answer to uneven heating. Addressing air leaks, ductwork issues, or airflow restrictions may improve comfort without requiring a new system.

A professional evaluation can help you understand your options and decide which solution makes the most sense for your home.

How Does Furnace Maintenance Affect Indoor Air Quality?

Regular furnace maintenance helps keep your heating system operating as intended and provides an opportunity to identify issues that may affect comfort, airflow, and system performance.

During a maintenance visit, an HVAC professional can inspect key components, check system operation, and evaluate concerns such as restricted airflow or unusual operating conditions.

Maintenance is also a good time to discuss persistent indoor air quality concerns, including excessive dryness, dust buildup, or inconsistent temperatures.

Keep in mind that furnace maintenance alone does not eliminate every indoor air pollutant. Humidity control, ventilation, filtration, and source control all play important roles in creating a healthier indoor environment.
