Indoor Air Quality Testing in Fort Collins, CO

You can't fix what you haven't measured. Indoor air quality testing is a professional assessment of what's actually in your home's air: particulates, volatile organic compounds, humidity levels, carbon monoxide, and ventilation effectiveness. We use calibrated instruments instead of guesswork. The result is a report th

Wall air vent supplying fresh, filtered air

Fort Collins gives us plenty to measure. Wildfire smoke season drives fine particulates indoors. Our dry climate swings humidity to extremes. Tightly built new homes can trap VOCs from finishes and furnishings. Testing turns vague worries into numbers.

What we test for

Particulate matter (PM2.5 and PM10): the fine dust, ash, and smoke particles that penetrate deep into lungs. Spikes during wildfire season and dusty windy days.
Volatile organic compounds (VOCs): off-gassing from paints, flooring, cabinets, cleaning products, and furnishings. Highest in new or recently remodeled homes.
Humidity: relative humidity readings room by room. Fort Collins homes often sit at 15–25% in winter (too dry) and swing with summer monsoons.
Carbon monoxide: ambient CO levels near combustion appliances and in living spaces. A safety-critical reading.
Carbon dioxide: a proxy for ventilation effectiveness. Chronically high CO2 means the house isn't getting enough fresh air.
Temperature stratification: hot and cold spots that indicate airflow and duct issues contributing to comfort complaints.

We also note the home's filtration setup, duct condition, and ventilation during the visit — the air doesn't exist separately from the system moving it.

How the testing visit works

Walkthrough interview. We ask about symptoms: odors, dust, allergy patterns, when problems are worst, recent changes to the home.
Instrument placement. Calibrated monitors go in key rooms — bedrooms, living areas, near the HVAC system — and log readings over a set period while the system runs normally.
Spot measurements. Handheld instruments check CO near the furnace and water heater, humidity room by room, and airflow at registers.
Your report. You get the numbers, what they mean against health and comfort benchmarks, the likely sources we identified, and prioritized recommendations. Those run from simple fixes (filter upgrades, humidity control) to equipment: filtration, humidifiers, ventilation.
No obligation. The test is diagnostic. You can take the report and do nothing, implement the easy fixes yourself, or have us handle the equipment side.

Why test before buying equipment

This is the point of testing first: a $400 air purifier is a great purchase if particulates are your problem and a waste if your issue is dry air or VOCs. Testing first means every dollar goes at the actual problem. We've seen homes where the "air quality problem" was a disconnected return duct pulling attic air, and homes where it was a new carpet off-gassing formaldehyde. Same complaint, completely different fixes. The instruments tell them apart in an afternoon.

Fort Collins IAQ patterns

The same local patterns show up again and again. Late-summer wildfire smoke pushes PM2.5 indoors even with windows closed — homes without good filtration see it in the readings. The EPA's guidance for smoky periods is a filter rated MERV 13 or higher. MERV is the filter efficiency scale, and 13 catches fine smoke particles. EPA testing found high-efficiency filtration can reduce indoor PM2.5 by about half when the system fan runs continuously. That's why your filter choice shows up directly in the numbers. Winter brings the opposite: single-digit humidity that dries sinuses, cracks woodwork, and makes static shocks a daily event. New builds in Timnath, Severance, and Windsor are tight and efficient, which is great for energy but means VOCs and CO2 accumulate without mechanical ventilation. And older homes with original ductwork often show particulate readings tied directly to duct leakage pulling in attic and crawlspace air.

What affects the cost of IAQ testing

Testing is a flat-rate visit based on home size — more rooms and more pollutant categories take more instrument time. The report and recommendations are included. If testing leads to equipment recommendations, those are quoted separately and there's no pressure to proceed.

Frequently Asked Questions

How is professional IAQ testing different from a home air monitor?

Consumer monitors measure one or two things with uncalibrated sensors. Professional testing uses calibrated instruments across multiple pollutant categories simultaneously, in multiple rooms, with a technician interpreting the results against benchmarks and identifying sources. A home monitor tells you a number; testing tells you what to do.

How long does indoor air quality testing take?

Plan on 2–3 hours. Instruments need time to log stable readings in each location, and the walkthrough interview and spot measurements fill the rest. You'll have the full report within a couple of days.

Can testing detect mold?

We measure the conditions mold needs — humidity, moisture, and particulate patterns — and we inspect for visible signs. But identifying specific mold species requires lab analysis of air or surface samples, which is a different service. If our readings point that way, we'll tell you and recommend a mold specialist.

Should I test before buying an air purifier?

Yes — that's exactly the use case. Testing tells you whether particulates, VOCs, humidity, or ventilation is the real issue, so you buy the right equipment instead of guessing. It's the difference between solving the problem and owning an expensive appliance.

Do new homes need air quality testing?

Often more than older ones. New construction off-gasses VOCs from finishes for months, and tight envelopes trap them inside. If your new home smells "new" for a long time or family members have headaches and irritation that ease when you leave, testing is worthwhile.

Will testing tell me if my ducts are the problem?

It points there strongly. Particulate readings that spike when the system runs, or CO2 and humidity patterns tied to airflow, usually trace back to duct leakage or filtration gaps. We cross-reference the air data with a duct inspection to confirm.
