Colorado Springs sits in a semi-arid high-plains climate where hot summer days and cold winter nights create repeated condensation cycles inside HVAC systems. Homes in older neighborhoods such as Old Colorado City often have metal duct runs in unconditioned attics or crawl spaces that collect moisture when temperatures swing sharply overnight. That moisture feeds mold on coils, drain pans and fiberglass-lined ducts, especially in houses near Cheyenne Mountain or the United States Air Force Academy where elevation and wind patterns increase air infiltration.
Technicians must separate the HVAC system from living spaces before any removal begins because spores can travel through the duct network into every room. In El Paso County, many systems installed before 1990 still use lined duct board that absorbs water and cannot be fully cleaned, requiring section replacement. Condensate drains clog with mineral scale from local hard water, leaving standing water that feeds colonies on evaporator coils and in the air handler cabinet itself.
After physical removal, negative-air machines and dehumidifiers run until moisture readings on wood and insulation drop below 12 percent. Technicians then apply EPA-registered antimicrobials labeled for HVAC use and replace filters with higher-MERV options suited to the dusty conditions near Garden of the Gods and Pikes Peak. Final clearance includes visual inspection plus air sampling to confirm spore levels match outdoor baselines before the system is returned to service.
Nearby cities such as Security-Widefield and Fountain share the same winter temperature inversions that push homeowners to run furnaces longer, increasing the chance of hidden growth behind registers. Work performed from the shop at 8003 N Academy Blvd stays within Mon–Fri 8am–6pm and Sat 9am–2pm so residents in Briargate or Rockrimmon can schedule around work and school hours.
Technician insight
In Colorado Springs the thing that catches most people out with HVAC mold remediation is the way cold winter nights pull warm moist air through poorly sealed ducts in older Old Colorado City and Manitou Springs homes, creating hidden growth behind registers that only shows up after the furnace runs hard for weeks.
Hidden coil growth in Briargate townhome
A homeowner in Briargate noticed musty air only when the heat kicked on. Inspection found black growth on the evaporator coil and clogged drain line inside a 1998 air handler. Technicians contained the system, removed the contaminated insulation, cleaned and treated the coil, then dried the cabinet to 10 percent moisture before reinstalling a new filter. The odor disappeared and follow-up sampling matched outdoor spore levels.

How it works
- 1
System Inspection
Technicians inspect coils, ducts, drain pans and insulation using borescopes and moisture meters while the system runs.
- 2
Containment Setup
Negative-air machines and plastic barriers isolate the HVAC equipment from occupied rooms before any disturbance.
- 3
Physical Removal
Moldy insulation, drain pan debris and growth on coils are removed by hand, followed by HEPA vacuuming of all surfaces.
- 4
Drying and Treatment
Dehumidifiers and air movers dry the system, then antimicrobial coatings are applied to cleaned metal and new insulation.
Pricing
Pricing varies by system size, extent of hidden growth and whether lined duct sections must be replaced.
