Air Duct Cleaning in Lawrenceville - One Price Per System, Agreed Before We Start

Air Duct Cleaning in Lawrenceville, GA

Whole-system HVAC cleaning in Lawrenceville typically runs $450-$850 for a standard residential job, with most homes in the area falling toward the higher end due to original flexible ductwork installed during Gwinnett County’s 1985-2005 building boom. We’re CleanRun Duct Repair & Cleaning, and our crews work the Lawrenceville market from our Atlanta office, carrying Rotobrush and Nikro negative-pressure extractors into attics that regularly hit 140°F in July. Every job starts with a written price before a panel comes off, and every duct run is photographed before and after. Call (678) 904-9744 for a free estimate.

Why Lawrenceville Homes Are Different

Lawrenceville sits at the core of Gwinnett County’s suburban explosion - the county was one of the fastest-growing in the US from the late 1980s through the 2000s, leaving a dense concentration of builder-grade homes now 25-35 years old with original flexible ductwork systems running through unconditioned attic spaces in Georgia’s brutal summer heat. That combination of age, cheap original materials, and extreme attic temperatures (often 140°F+) means flex duct has sagged, kinked, and accumulated decades of Georgia’s notorious pollen, red-clay dust, and humid-air biofilm in ways that neighboring newer Forsyth County builds or older Decatur-era homes simply don’t replicate.

The dominant housing stock is large, two-story suburban tract homes built in 1985-2005 subdivisions throughout eastern Gwinnett County, almost universally constructed with flexible duct systems routed through vented attics rather than hard-pipe trunk lines. These homes frequently have 4-5-ton multi-zone systems with long duct runs that are now at or past typical service life, and many were never professionally cleaned since original installation. Technicians working the older subdivisions off Sugarloaf Parkway and around the Lawrenceville Highway corridor regularly find original late-1990s flex duct with inner liner separating from the outer jacket - a failure mode accelerated by years of 140°F attic heat - that collapses partially under suction during cleaning and requires camera inspection before any aggressive agitation to avoid blowing debris into living spaces.

Lawrenceville’s Georgia Piedmont climate delivers high humidity and heavy spring pollen loads - Gwinnett County regularly records some of the highest pine and oak pollen counts in the Southeast - which means return-air intakes pull a significant particulate burden into systems every March through May. The same summer humidity creates condensation risk inside attic-run flex duct, making mold accumulation inside aging ductwork a genuine and recurring finding rather than an upsell scare tactic.

Our Main Lawrenceville Services

Most Lawrenceville homeowners who call us start with one of these three services, each with its own dedicated local page.

Air Duct Cleaning in Lawrenceville

We clean the full duct network - supply and return runs, trunk lines, and plenum - using negative-pressure extraction with Rotobrush agitation. In Lawrenceville’s 1990s subdivisions, we typically find 2-4 inches of compacted pollen and red-clay dust at the first elbow off the plenum, plus sagging flex duct that has to be camera-inspected before we apply full suction. Every run is photographed before and after. Air Duct Cleaning in Lawrenceville covers the full scope and pricing.

Dryer Vent Cleaning in Lawrenceville

Dryer vent blockages are common in Lawrenceville’s two-story homes where the vent run extends 20-35 feet through attic space to a roof or soffit termination. We pull the lint load with a Nikro rotary brush and measure airflow before and after. The photo record shows the obstruction removed, not just claimed. Dryer Vent Cleaning in Lawrenceville has full details.

Duct Repair & Sealing in Lawrenceville

When camera inspection shows separated flex liner, collapsed runs, or disconnected boots in Lawrenceville’s original 1990s ductwork, we repair or replace the damaged section and seal with mastic. No work starts without a written price under Haven Standard Clause 1. Duct Repair & Sealing in Lawrenceville explains the process.

Before

After

HVAC Cleaning in Lawrenceville

Lawrenceville’s 25-35-year-old systems need more than duct cleaning - the components that actually move and condition air are coated with the same pollen, dust, and biofilm that lines the ductwork. HVAC Cleaning addresses the evaporator coil, blower assembly, condenser, and air handler as integrated parts of one system, not isolated add-ons. In this market, we regularly find evaporator coils completely blocked by compacted debris that has bypassed the filter, and blower wheels throwing out of balance from uneven dust loading.

Evaporator Coil Cleaning

Signs you need it

Ice buildup on the refrigerant lines, weak airflow from registers, or cooling that can’t keep up on 95°F July afternoons in Lawrenceville.

What it costs in Lawrenceville

Evaporator coil cleaning typically runs $280-$450, with heavily fouled coils in older Gwinnett County systems toward the upper end.

How we do it

We remove the coil access panel, apply foaming cleaner, rinse with low-pressure water, and photograph the before and after condition for the job record.

Blower Cleaning

Signs you need it

Vibration noise from the air handler, uneven airflow room-to-room, or a blower wheel visibly caked with dust when the panel is removed.

What it costs in Lawrenceville

Blower assembly cleaning ranges from $220-$380 depending on whether the wheel requires full removal for access.

How we do it

We disconnect power, extract the blower assembly, clean the wheel and housing with compressed air and solvent, balance-check the wheel, and reinstall with torque to spec.

What HVAC Cleaning Costs in Lawrenceville

Why does my Lawrenceville home’s AC smell musty when it first turns on?

Musty startup odor usually means biofilm on the evaporator coil or standing water in the condensate pan, both common in Lawrenceville’s humid climate with aging systems. We clean the coil, pan, and drain line, then photograph the result. Call (678) 904-9744 for an exact quote - estimates are free.

Can HVAC cleaning fix weak airflow upstairs in my two-story Lawrenceville home?

Weak upstairs airflow often comes from a dirty blower wheel running below rated RPM, a blocked coil raising static pressure, or collapsed flex duct in the attic - all inspectable and correctable. We measure static pressure before and after to document the improvement.

Air Quality & Sanitizing in Lawrenceville

Lawrenceville’s combination of 140°F attic heat, high humidity, and original flex duct creates conditions where mold and bacteria colonize duct interiors - not hypothetically, but as a recurring finding our cameras document. Air Quality & Sanitizing treats these biological loads with targeted application, not fog-and-hope. We use Abatement Technologies and Honeywell equipment, and we photograph the treatment area before and after every application.

Mold Treatment

Signs you need it

Visible mold at registers, musty odor that persists after duct cleaning, or a history of condensation inside attic ductwork.

What it costs in Lawrenceville

Spot mold treatment runs $350-$600; whole-system treatment for a typical 4-ton Lawrenceville home ranges $800-$1,400.

How we do it

We apply EPA-registered antimicrobial directly to affected surfaces with controlled droplet size, avoid overspray into living spaces, and include post-treatment air sampling in the deliverables.

UV Light Installation

Signs you need it

Recurring mold after treatment, chronic musty odor, or a medical recommendation for reduced airborne bioburden.

What it costs in Lawrenceville

UV-C lamp installation at the coil or supply plenum typically costs $450-$750 including the lamp, ballast, and wiring.

How we do it

We mount the lamp with sight-glass access for annual bulb replacement, wire to the air handler’s 24V circuit, and show the customer the operating lamp before we close the panel.

What Air Quality & Sanitizing Costs in Lawrenceville

Is mold in Lawrenceville ducts common or are you trying to upsell me?

Mold is a genuine recurring finding in Lawrenceville’s original flex duct, where attic heat plus humidity creates condensation on the inner liner - we photograph it before mentioning treatment, and we show you the image. No treatment happens without a written price under Haven Standard Clause 1.

Does UV light actually work in Georgia’s humidity?

UV-C at the coil surface prevents biofilm regrowth by continuous irradiation; it does not scrub the air passing through. We install for customers with documented recurrence after mold treatment, with the lamp’s spec sheet included in the job record.

Brands We Service in Lawrenceville

We stock parts and service equipment from Honeywell, Aprilaire, Abatement Technologies, and other major brands - our technicians carry common filters, UV lamps, and coil cleaners on the truck. Most Lawrenceville repairs don’t require a return visit. See our brands for the full roster.
