Indoor air can affect how your home feels every day, from sleep quality to comfort, odours, humidity, and how often dust seems to return. If you want to improve indoor air quality, you do not always need a major renovation or expensive equipment. The biggest results often come from simple habits and a few targeted upgrades that reduce pollutants, increase fresh air, and keep your HVAC system operating the way it was designed.
Comfort Living HVAC helps homeowners in London, Ontario improve indoor air quality with practical, home specific recommendations. In this guide, you will learn straightforward steps you can do today, what changes matter most in winter, how to choose filtration that fits your system, and how to create a simple routine that keeps air cleaner all year.
Start With Ventilation And Fresh Air Basics
To improve indoor air quality, ventilation is one of the most important foundations because it helps remove stale air and replaces it with fresh outdoor air. Health Canada explains that ventilation can help improve indoor air quality by removing pollutants from the home and by bringing in fresh air from outside, especially during renovations or when using chemical products indoors. If your home feels stuffy, smells linger, or humidity builds up, improving ventilation can make a noticeable difference quickly.
To improve indoor air quality without overcomplicating it, think in terms of controlled air exchange. That can be as simple as using kitchen and bathroom exhaust fans properly, opening windows when weather permits, and ensuring your mechanical ventilation systems actually run as intended. A consistent approach to ventilation is often the fastest path to improve indoor air quality because it reduces buildup of common indoor contaminants.
Use Exhaust Fans The Right Way
To improve indoor air quality during cooking and showering, use your kitchen and bathroom fans and let them run long enough to clear moisture and odours. Many homes create humidity problems simply because the fan is used too briefly, or not at all, which allows moisture and particles to spread into the rest of the house.
Know When To Use Natural Ventilation
To improve indoor air quality with outdoor air, short periods of window opening can help in mild weather, especially after cleaning or cooking. In winter, you may rely more on mechanical ventilation and spot ventilation because open windows can create comfort and energy loss issues.
Control The Biggest Indoor Pollutant Sources
If you want to improve indoor air quality, it helps to reduce pollutants at the source instead of trying to filter everything after the fact. Smoke, candles, incense, strong cleaning chemicals, off gassing from some materials, and even hobby activities can add particles and chemicals to indoor air. Reducing these sources can immediately improve indoor air quality because you are lowering what your system has to manage.
To improve indoor air quality in a realistic way, focus on the rooms and activities that create the most impact. Kitchens, bathrooms, basements, and attached garages are common areas where pollutants and moisture accumulate. When you reduce sources and manage moisture, you improve indoor air quality and also reduce the risk of mould, musty smells, and condensation on windows.
Cooking And Combustion Byproducts
To improve indoor air quality, use your range hood when cooking and keep it clean so it can move air effectively. Combustion sources like gas cooking or fuel burning appliances can add pollutants, so good ventilation and maintenance matter, especially in winter when windows stay closed more often.
Moisture Control Prevents Air Quality Problems
To improve indoor air quality, keep indoor humidity in a healthy range and address condensation quickly. Excess moisture can encourage mould and dust mites, and it often makes a home feel stale even when the temperature is comfortable.
Filtration That Actually Works With Your HVAC System
To improve indoor air quality through filtration, you need a filter that matches your system’s airflow requirements. A filter that is too restrictive can reduce airflow, which can make heating and cooling less even and can cause your system to work harder. The Public Health Agency of Canada notes that higher MERV filters can reduce airflow through forced air systems if the system cannot handle them, and recommends consulting the system manual or an HVAC professional to confirm compatibility. This is why the best plan to improve indoor air quality is not always the highest rated filter.
To improve indoor air quality with less guesswork, start with the filter type your furnace or air handler was designed to use, then adjust based on your home’s needs. Homes with pets, allergy concerns, or heavy dust often benefit from a better filter, but only when airflow remains strong. Comfort Living HVAC can help you choose a filter that helps improve indoor air quality without introducing comfort problems.
Build A Filter Routine You Will Follow
To improve indoor air quality, filters must be replaced on schedule, not only when the system seems to struggle. A simple monthly check and a consistent replacement routine can improve indoor air quality because it keeps airflow steady and prevents buildup in the system.
Consider Whole Home Filtration Upgrades Carefully
To improve indoor air quality beyond basic filters, some homes benefit from media filter cabinets or upgraded filtration setups. The best choice depends on your system design, duct layout, and indoor air goals, so it is worth reviewing options with a technician.
Keep Your System Clean And Maintain Airflow
If you want to improve indoor air quality, your HVAC system should be maintained so it can circulate and condition air properly. Dirty coils, clogged drains, and neglected components can contribute to odours, moisture problems, and reduced airflow. Many homeowners try to improve indoor air quality with an air purifier while ignoring the basics of system performance, which often limits results.
To improve indoor air quality, focus on airflow pathways: return vents should be unobstructed, supply vents should not be blocked, and filters should fit correctly. When airflow is balanced, your system can mix and distribute conditioned air more evenly, which helps improve home air quality and makes the home feel more consistent from room to room.
Do Not Block Return Air Pathways
To improve indoor air quality and comfort, keep return grilles clear of furniture, curtains, and storage. Returns are how air gets back to the system for filtration and conditioning, so blocked returns can reduce circulation and make air feel stale.
Schedule Preventive Maintenance
To improve indoor air quality long term, seasonal maintenance helps confirm the system is operating safely, efficiently, and cleanly. A professional visit can also identify issues like duct leakage or improper fan settings that reduce circulation.
Ventilation Systems And HRVs For Year Round Fresh Air
Many Canadian homes benefit from dedicated mechanical ventilation, especially when the home is fairly airtight or when winter keeps windows closed. To improve indoor air quality consistently, a heat recovery ventilator can exchange stale indoor air with fresh outdoor air while reducing heat loss. Natural Resources Canada explains that a properly installed and maintained HRV exhausts indoor air pollutants and excess humidity while distributing fresh air into the home. This can be a strong option if you want to improve home air quality without relying on window opening.
To improve indoor air quality with HRV or ERV equipment, maintenance matters. Filters and cores need cleaning, outdoor hoods must stay clear, and airflow settings should match your household use. If ventilation equipment is turned off or neglected, the home may feel stuffy and humidity can rise, which works against your goal to improve indoor air quality.
When An HRV Makes Sense
To improve indoor air quality, HRVs are often helpful in homes with persistent condensation, odours that linger, or rooms that feel stale even when heating and cooling are running. They are also useful when you want more predictable fresh air during winter.
Maintenance Keeps Ventilation Effective
To improve indoor air quality with an HRV, you need a simple maintenance routine for filters and the core. A neglected ventilator cannot deliver the consistent air exchange that makes these systems valuable.
Simple Cleaning Habits That Improve Indoor Air Quality
You can improve indoor air quality with small routine habits that reduce dust, allergens, and moisture. Regular vacuuming with a good quality vacuum, damp dusting instead of dry wiping, and keeping clutter down can reduce particles that otherwise get stirred into the air. These steps seem basic, but they often create noticeable results for homeowners trying to improve indoor air quality without major upgrades.
To improve home air quality even more, focus on entry control and textiles. Use mats at doors, remove shoes when possible, wash bedding regularly, and keep pet areas clean. These practices reduce what becomes airborne, which means your filters have less to capture and your home can feel cleaner between deep cleanings.
Choose Low Scent Cleaning Products
To improve indoor air quality, consider using milder cleaning products and ensure good ventilation when using stronger chemicals. Health Canada notes ventilation is especially important when using chemical products in the home.
Address Basement And Crawl Space Sources
To improve indoor air quality, manage moisture and odours in basements, because air from lower levels can move upward through the home. Dehumidification, sealing obvious gaps, and improving ventilation can reduce musty air that circulates into living spaces.

Seasonal Tips For Winter And Summer In Ontario
To improve indoor air quality in winter, focus on moisture, ventilation, and filtration because homes are sealed tighter and heating systems run longer. Winter air can feel dry, but indoor humidity can still rise from cooking and showers, leading to condensation and musty smells. Consistent ventilation and proper fan use help improve indoor air quality while maintaining comfort.
To improve home air quality in summer, focus on controlling outdoor pollutant entry and managing humidity. Air conditioning can help reduce humidity, but only if the system is sized and maintained properly. If summer humidity stays high, you may feel sticky and notice odours lingering, so improvements to airflow, dehumidification, and ventilation can help improve indoor air quality through the warm season.
Allergy Season And Wildfire Smoke Considerations
To improve indoor air quality during high pollen days or smoke events, keep windows closed when needed and rely on filtration and controlled ventilation strategies. Your approach may shift depending on outdoor conditions, so having a flexible plan helps improve indoor air quality without sacrificing comfort.
