The Purpose of Indoor Air Quality (IAQ) Tests
An IAQ test measures the concentration of airborne contaminants inside your home or building. The goal is to identify pollutants that aren’t visible to the naked eye but can influence your comfort, health, and even HVAC system performance. Certified testing provides precise measurements of key pollutants such as radon, volatile organic compounds (VOCs), carbon monoxide (CO), and particulate matter (PM2.5), among others.
- Improve respiratory health by eliminating hidden triggers like mold and dust.
- Reduce headaches, fatigue, and allergic reactions by identifying pollutant sources.
- Ensure compliance with government air safety standards — vital for rental properties and real estate transactions.
What Pollutants Are Commonly Tested
Home air testing typically focuses on several high-impact pollutants:
- Radon gas – A naturally occurring radioactive gas that seeps into homes from the soil.
- VOCs – Emitted from paints, solvents, adhesives, and household cleaning products.
- Mold spores – Thrive in damp or poorly ventilated areas, often linked to high humidity levels.
- Carbon monoxide – An odorless gas from incomplete combustion appliances and heating systems.
- PM2.5 and PM10 – Fine particulate matter from outdoor air, smoke, and indoor objects like candles.
Health Risks of Undetected Air Issues
Prolonged exposure to poor indoor air isn’t just uncomfortable — it can be dangerous. High radon levels are the second leading cause of lung cancer in Canada. Mold spores can trigger asthma attacks, while VOCs and CO lead to chronic fatigue and nausea. Children, seniors, and those with pre-existing respiratory conditions are particularly vulnerable to indoor air pollutants left unmonitored.
“A proper air quality test can detect invisible health risks like radon, VOCs, and mold spores.”
If you’ve never conducted an IAQ test in your Calgary home, now is the time to assess what you’re really breathing.
Why Air Quality Testing Matters in Calgary
Protect your Calgary home and family with expert air quality testing services.
Living in Calgary brings unique environmental challenges that can significantly impact your indoor air quality. From high radon exposure due to our local geology to the sudden infiltration of wildfire smoke during summer, Calgary residents face air quality risks that are both seasonal and systemic. Professional indoor air testing is your first defense against these invisible threats.
How Calgary’s Geology Impacts Indoor Air (Radon Zones)
Calgary sits in one of Canada’s highest radon emission zones due to its underlying bedrock and soil composition. This means that radon gas — a naturally occurring radioactive substance — easily seeps into homes through foundational cracks and sump pits. Over 50% of homes tested in Calgary exceed Health Canada’s safety guideline of 200 Bq/m³ for radon. Without testing, there’s no way to detect this health threat.
Don't leave your family's health to chance. A professional home radon test in Calgary takes the guesswork out of indoor air quality. Calgary Radon Detection uses Health Canada-approved methods to deliver results you can act on. Schedule your test now.
“Calgary sits in a known radon hot zone, increasing risk of exposure in homes.”
Seasonal Factors Like Dry Winters and Wildfire Smoke
Dry, frigid winters in Calgary drive residents indoors and decrease natural ventilation, amplifying indoor air contaminants from gas heating, fireplaces, and low humidity. During wildfire season, outdoor smoke and particulates (PM2.5) also enter homes via drafty windows or HVAC systems, degrading indoor air even when you keep doors shut.
- Low humidity causes dry airways and can exacerbate asthma symptoms.
- Wildfire smoke infiltration raises PM2.5 levels far above healthy thresholds, even indoors.
“Wildfires and dry winters intensify poor indoor air during Calgary seasons.”
Who Is Most at Risk in the Calgary Region
Infants, seniors, and individuals with respiratory issues are especially vulnerable. However, even healthy adults can experience chronic symptoms due to unclean indoor air. Renters and property managers should also consider IAQ testing to comply with safety standards and minimize tenant liability. Calgary homes built pre-1980 can be more susceptible due to older ventilation and insulation systems.
When local conditions elevate risk, proactive air quality testing helps Calgary families breathe easier year-round.
Common Indoor Air Pollutants Found in Calgary Homes
A visual overview of household air contaminants like VOCs, radon, and PM2.5, highlighting the importance of professional air quality testing in Calgary.
Even spotless Calgary homes can host serious airborne contaminants that escape the naked eye. From basement radon seeping undetected to VOCs off-gassing from everyday products, pollutants vary based on building materials, HVAC performance, and external environmental conditions. Understanding what you’re up against is the first step in safeguarding your indoor air.
Radon Gas
Radon is responsible for over 3,000 lung cancer deaths in Canada yearly. It infiltrates homes through foundation cracks and accumulates, especially in basements. Calgary has among the highest concentration of at-risk homes. Because it’s odorless and invisible, a long-term radon test is the only way to confirm if levels are safe.
“Over 50% of Calgary homes tested have radon levels above the Health Canada guideline.”
Volatile Organic Compounds (VOCs)
VOCs are emitted by hundreds of common household products — from paint and varnish to air fresheners and new furniture. In poorly ventilated homes, VOC buildup leads to chronic headaches, allergic reactions, and throat irritation. Renovated homes or new builds often show elevated VOC levels due to fresh construction materials.
“VOCs come from paints, cleaning products, and synthetic home materials.”
Mould Spores and Humidity
Moisture-rich environments like bathrooms and unfinished basements are hotspots for mold growth. In Calgary, where cold winters and humidifiers can skew household moisture levels, testing for mold spores and tracking relative humidity is vital. Mould exposure can aggravate asthma and cause long-term respiratory issues, even in minimal concentrations.
Particulate Matter (PM2.5), Carbon Monoxide
Fine particulate matter (PM2.5) and carbon monoxide (CO) are combustion by-products from stoves, furnaces, and external wildfire smoke. They reduce oxygen intake and are dangerous in enclosed spaces. Carbon monoxide in particular is odorless and lethal, which is why every Calgary home should have both functional CO alarms and professional IAQ assessment.
Regular air quality monitoring helps detect these pollutant threats before they disrupt health or home comfort in Calgary properties.
Professional vs DIY Air Quality Testing

Thinking about checking your home’s air quality on your own? As a Calgary homeowner or property manager, you may be comparing store-bought test kits to professional inspections. While DIY air test kits offer convenience, they often fall short when it comes to accuracy and comprehensiveness—especially for critical contaminants like radon gas or volatile organic compounds (VOCs). Understanding when to rely on certified professionals versus going the DIY route can directly impact your home’s safety and your peace of mind.
Limitations of store-bought or online test kits
DIY indoor air quality test kits, commonly sold online or in hardware stores, typically use basic chemical strips or low-cost sensors to measure pollutants. While they may detect general issues like humidity or basic mold presence, these kits fail to accurately measure gases like radon or carbon monoxide. Most do not provide real-time monitoring or laboratory-grade analysis, meaning results can be misleading or incomplete. False negatives are especially risky when it comes to long-term exposure to hazardous substances.
What makes professional testing more accurate
Certified air quality inspections utilize calibrated equipment, advanced digital sensors, and local lab partnerships to identify a full range of indoor pollutants. Technicians trained in environmental sciences analyze data not just on airborne particles, but also on hidden biological and chemical threats present in walls, basement foundations, and HVAC systems. Professional services can include radon detection, VOC sampling, mold air spore counts, and carbon monoxide analysis—often in a single comprehensive visit.
Professional testing uses laboratory-grade equipment calibrated for accuracy—DIY kits rarely capture radon or VOCs correctly.
When it’s worth bringing in a certified expert
If your household includes children, seniors, or anyone with respiratory issues, professional air quality testing is not just advisable—it’s essential. Homes in Calgary with finished basements are particularly susceptible to radon gas accumulation, especially in older neighborhoods or those with clay-heavy soils. If you suspect indoor air pollution, have recently renovated, or are preparing to sell or rent a property, certified testing provides clear documentation and certified remediation guidance if needed.

Improving Your Indoor Air Quality After Testing
A well-maintained HVAC system is essential for effective air quality testing and healthy living in Calgary homes.
Received your air quality test results and found concerning levels of radon, VOCs, or mold spores in your Calgary home? You’re not alone—and more importantly, there are proven steps to improve indoor air safety permanently. Whether your testing was part of a real estate transaction, a renovation, or a general wellness checkup, taking action quickly helps reduce health risks and boosts home value.
Installing air filtration or purification systems
High-efficiency particulate air (HEPA) filters and active carbon purifiers play an essential role in filtering out airborne contaminants like fine particles (PM2.5), allergens, and chemical gases. Many Calgary residents choose whole-home systems that integrate directly into ductwork for continuous, room-by-room purification. Portable purifiers are also effective when placed in bedrooms, nurseries, or lower levels prone to air stagnation.
Improving HVAC and ventilation systems
Optimizing your home’s HVAC and ventilation ensures air is circulating and filtering properly year-round. Solutions include installing energy recovery ventilators (ERVs), boosting fresh air exchange, and sealing leaks near utility penetrations. A properly maintained HVAC system not only regulates temperature, but also controls humidity and helps prevent mold growth in Calgary’s varied climate zones.
Proper ventilation helps maintain healthy humidity and prevent mould buildup.
Reducing sources of indoor air pollution
Identifying and removing household products high in VOCs is a critical step. Common culprits include synthetic carpets, glues, paints, air fresheners, and unvented gas appliances. Choosing low-VOC finishes and storing chemicals in garages or sealed containers can reduce exposure significantly. Additionally, smoke from fireplaces or tobacco can introduce fine particulate matter that remains trapped in closed spaces.
When mitigation for radon, mould, or VOCs is necessary
Radon mitigation systems such as sub-slab depressurization can lower radon levels by over 90%, often below Health Canada’s recommended 200 Bq/m³ limit. Mold mitigation may involve air duct cleaning, HEPA vacuuming, and targeted remediation in drywall or insulation. If VOCs are persistent, sealing crawlspaces and updating materials using certified green alternatives will help create lasting indoor air improvements.
