Cleaning & Care
Air Duct Cleaning
Our negative-air machine seals onto the main trunk duct and puts the whole system under suction first. Then each run is scrubbed individually, so years of dust and debris travel one way only — out of the ducts and into the machine. The visit also covers the returns, where pet dander mats heavily in a house closed up against the heat. Air Duct Cleaning in Lawrenceville, GA is one call away, every day of the week.

A duct system in Lawrenceville cools through a long, humid season, breathes some of the heaviest pollen in the country and often runs through a crawlspace. This is what we actually find here, and what we check on every visit.
A large share of Lawrenceville homes run their ductwork through a vented crawlspace that stays humid most of the year. Dust inside those ducts sits in moisture, joints sweat, insulation gets damp, and the musty smell that follows is a duct problem before it is anything else.
In a dry climate dust stays loose; in Gwinnett County it cakes. Moisture makes the dust inside ductwork cling and build in layers, so a Southeast system can look worse at five years than a desert system at ten - and a surface wipe at the registers does nothing for what is packed in the trunk.
Two-story Lawrenceville homes usually cool the upstairs through attic ductwork that bakes all afternoon. Heat ages flex duct, dries out taped joints and sags loose straps, so the upstairs - the rooms that need the air most - get the least of it.
Gaps in return runs are common in Georgia homes, and a return that leaks pulls unfiltered air from attics, garages and wall cavities - dust, insulation fibers and fumes included - and sends it through the house, bypassing the filter entirely.

It removes a real reservoir. Lawrenceville pollen loads the return side heavily each spring, and the system keeps recirculating it after the season ends. Cleaning the trunk and returns out means the house stops re-dosing itself. It is not a medical treatment, but most families notice dust settling more slowly afterward.
Usually the attic ductwork: joints leaking cooled air, runs sagging between straps, or an undersized return starving the second floor. In Gwinnett County we trace the upstairs runs end to end on the inspection, and repair or sealing normally closes most of the gap.

Where ducts run through attics and crawlspaces - most Lawrenceville homes - leaks spill cooled air outside the living space, and sealing them means the AC runs less to hold the same temperature. We check for leaks on every inspection and tell you plainly which work would pay off.
