Our indoor air quality services
We treat indoor air quality as a system, not a single product. Here are the four core services we install across Plainfield and Hendricks County - usually in some combination, depending on what your home actually needs.
Whole-Home Duct Cleaning
High-volume vacuum from the trunk plus per-run agitation - debris actually exits the house instead of just shifting around. Includes return drops, supply runs, plenums, and grilles, with before/after photos so you see exactly what came out.
- Removes dust, dander, drywall debris, rodent contamination
- Standard on post-2005 builds that never had construction debris cleared
- Pairs with a media filter upgrade for lasting results
UV Light Installation
Coil-mounted UV-C lamps installed at the indoor evaporator coil to kill mold, bacteria, and biofilm as air passes through. Fixes the musty AC smell at the source - no scented filters, no recurring coil cleanings.
- Targets mold and microbes on the coil and drain pan
- Permanent fix for AC-on musty odors
- Annual bulb replacement keeps it working at full intensity
Whole-Home Air Purifier
AprilAire and similar whole-home purifiers integrate into your existing ductwork to capture particles down to 0.3 microns - allergens, smoke, virus-sized particulates - on every cycle of the system. Works with any furnace or air handler we service.
- MERV 16 / 4-5 inch media or polarized-media options
- No filter changes every month - typical service interval is 12 months
- Best fit for households with allergies, asthma, or pets
Whole-Home Humidifier & Dehumidifier
Bypass and steam humidifiers for winter dryness; ducted dehumidifiers for sticky summers and damp basements. Sized to your home and tied into the thermostat or a dedicated humidistat so you set it once and forget it.
- Targets the 35-50% comfort and health humidity window
- Stops cracked wood floors, static shocks, sinus irritation
- Dehumidifiers cut basement musty smell at the source
Plainfield homes, Plainfield air problems
Air quality issues track closely with when your house was built. After thousands of jobs across Hendricks County, here's the pattern we see in Plainfield:
Older Plainfield homes (pre-1990)
Main Street, Saratoga, Hummel Park, downtown Plainfield
- High humidity loads. Crawlspaces and unfinished basements pump moisture into the house all summer - musty smells, sticky upstairs.
- Decades of duct buildup. Original ductwork that was never cleaned, often with insulation shedding inside.
- Mold-prone coils. Older AC coils + high humidity = the AC-on musty smell every June.
Typical fix: dehumidifier + duct cleaning + coil-mounted UV.
Newer Plainfield builds (2005+)
Hadley Ridge, Saratoga, Settler's Ridge, post-2005 subdivisions
- Tight envelope, no fresh air. Sealed-tight construction with no dedicated ventilation - stale air, lingering cooking and chemical odors.
- Construction debris in the ducts. Drywall dust, sawdust, and fasteners from the build that nobody ever vacuumed out.
- Duct sealing problems. Aggressive flex-duct runs and flimsy builder boots leak unfiltered attic air past the filter.
Typical fix: duct cleaning + air handler sealing + media filter upgrade.
Either way, we start with a free duct inspection and a humidity reading at the return - then recommend the smallest fix that actually solves the symptom.

UV light vs. whole-home air purifier - what's the difference?
Two of our most-asked-about IAQ products solve completely different problems. We install both, often together - here's how to think about which one fits your symptoms.
