Air Duct Cleaning in Greenville, SC
AC Repairs Greenville provides duct cleaning services to homes and businesses across Greenville and surrounding neighborhoods.
Duct cleaning is one of the most over-sold home services in the country. Bait pricing, scare tactics, and pictures of “what we found in your ducts” — most of it borderline scam. AC Repairs Greenville does honest duct cleaning: we inspect first, tell you if you actually need it, and charge a flat price for the work without bait-and-switch.
The truth is most homes don’t need their ducts cleaned regularly. Most do need it once after a renovation, once when they buy an older home with no maintenance history, or once when there’s a specific reason — pest intrusion, water damage, smoke event, or visible mold.
When duct cleaning makes sense
Real reasons to clean your ducts:
- Recent renovation. Drywall dust, sawdust, and demo debris get pulled into the return ducts and recirculated. Post-renovation cleaning makes a real difference.
- New homeowner of an older home. You don’t know what’s in there. One thorough cleaning gives you a baseline to start from.
- Visible mold or biological growth. Worth investigating fast — usually a moisture problem upstream that also needs fixing.
- Pest intrusion. Rodents in attics often nest in duct insulation and supply lines. Cleaning + sealing the entry point.
- Persistent unexplained respiratory issues. Worth ruling out as a factor, especially in older homes with original ductwork.
- Smoke or fire event in the home. Ducts hold smoke residue for years if not cleaned properly.
Reasons that are NOT good reasons to clean ducts
Some pitches we hear from homeowners who’ve been told they “need” duct cleaning:
- “There’s some dust on the supply register.” Normal. Wipe it.
- “I saw a coupon for $99 duct cleaning.” That’s a bait price. Real duct cleaning isn’t $99.
- “I haven’t had it done in 10 years.” Time alone is not a reason. Condition is.
- “A company in an unmarked van knocked on my door and said my ducts were full of mold.” Walk away. Don’t pay anything. Don’t sign anything.
What proper duct cleaning involves
The NADCA (National Air Duct Cleaners Association) standard is the right benchmark. Done correctly:
- Inspect first. Open access panels, look inside the system with a camera or scope. Photograph the actual condition.
- Quote based on inspection. Flat-rate, no surprise add-ons.
- Seal off the system. All supply and return registers covered to prevent dust release into rooms.
- Negative pressure with HEPA filtration. Industrial vacuum at the system access points, pulling debris out without releasing it into the home.
- Agitate the duct interior. Powered brushes, compressed air whips, or both depending on duct material.
- Clean the air handler. Coil, blower wheel, plenum — the actual dirty parts. If a “duct cleaning” doesn’t include this, it’s not really duct cleaning.
- Replace the air filter with the right MERV rating for your system.
- Photograph after so you can see what was actually done.
A real residential duct cleaning takes 4–6 hours. If someone quotes 90 minutes, they’re not doing it right.
