AC Duct Cleaning

Our AC duct cleaning process is methodical from start to finish. Here is exactly what happens when our technician arrives at your home.

We start by walking through your home and identifying every supply vent and return air grille. Before we begin the physical cleaning, we recommend an air duct inspection so we can see what is actually inside your ductwork. Mold, rodent debris, collapsed sections, or heavy contamination each require a different approach. The inspection gives us — and you — a clear, honest picture of your duct condition before any work begins.

Once we know what we are dealing with, we connect a commercial-grade, truck-mounted or portable negative pressure vacuum system to your duct network. This machine creates powerful suction that pulls loose dust, pollen, pet dander, mold spores, and debris out of the ducts and into a sealed collection unit. Nothing recirculates back into your living space. We then work through each duct branch using rotary brushes and compressed air tools to agitate and dislodge stubborn buildup clinging to duct walls and bends.

Every supply duct, return duct, and main trunk line gets cleaned. All registers and grilles are removed, scrubbed individually, and reinstalled. After the primary cleaning is complete, many homeowners choose to add air duct sanitizing — an EPA-registered antimicrobial treatment applied directly inside the ductwork to reduce mold, bacteria, and odor-causing organisms. This is especially valuable for homes with pets, young children, or anyone with respiratory sensitivities.

This full AC duct cleaning process is part of the broader air duct cleaning services Hoffner Heating & Air Conditioning provides throughout Western Pennsylvania — all aimed at improving indoor air quality and keeping your cooling system performing at its best throughout the summer months.
