Montrose sits in a high desert climate where hot summers and cold winters drive long heating seasons. Older homes on the Northside and Southside often have leaky ductwork and outdated furnaces that pull in fine dust from the surrounding terrain. Indoor air quality testing begins with measuring particulate levels and checking for carbon monoxide near combustion appliances, especially in houses close to the Montrose County Courthouse or Ute Indian Museum where many structures date to the mid-20th century.
Cerro Summit and the ridgeline winds that sweep through the valley carry pollen and mineral dust that settle on roofs and enter attic returns. Technicians test supply and return air at multiple points, compare readings to outdoor baselines taken near Delta and Ridgway, and note how elevation and dry air affect filter loading. Homes with crawl spaces or unconditioned attics commonly show elevated moisture and mold spores once winter humidity drops.
Testing also covers volatile organic compounds from household products and radon infiltration common in Montrose County soils. Results guide specific recommendations such as upgraded filtration, sealed combustion units, or ventilation adjustments rather than generic filter swaps. Every report includes photos of test locations and a prioritized list of repairs that match the actual conditions found on site.
Technician insight
In Montrose the thing that catches most people out with indoor air quality testing is how quickly fine dust from the high desert gets pulled into returns once winter temperatures drop and furnaces run nonstop; homes near Cerro Summit or on the Southside often show double the particulate counts of newer builds because the original ductwork was never sealed.
Northside Furnace Dust Issue
Homeowner on the Northside noticed increased allergy symptoms after the first cold snap. Testing showed elevated PM levels near the return in the attic. We located gaps in the original ductwork that were drawing in dust from the roofline. Sealing the joints and adding a higher-efficiency filter dropped indoor readings to match outdoor baselines.
