Frequently Asked Questions

How much does professional air duct cleaning actually cost in Guilford County?
For an average-sized home in Guilford County, you’re looking at somewhere between $450 and $1,000 for a complete, professional cleaning. The price depends on your home’s size, how many vents you have, and how accessible your ductwork is. If you see ads for $99 whole-house specials, that’s usually a red flag. Those prices often come with hidden fees or incomplete service. Real duct cleaning takes time, proper equipment, and trained technicians. We give you a clear quote upfront based on what your system actually needs.
Most homes benefit from cleaning every three to five years, but it’s not one-size-fits-all. If you have pets that shed, someone in your home has allergies or asthma, you’re a smoker, or you’ve recently renovated, you might need it more often. The EPA doesn’t recommend routine cleaning just for the sake of it. Instead, focus on signs like visible dust around vents, musty smells, uneven airflow, or if you’ve never had it done and don’t know the history. We’ll tell you honestly whether your ducts need attention or if you can wait.
A thorough, professional cleaning typically takes between two and five hours, depending on your home’s size and how dirty the system is. Homes with multiple HVAC units or years of buildup may take longer. If someone tells you they can clean your whole house in 30 minutes, they’re not doing it right. Real cleaning involves inspection, setting up powerful vacuum equipment, cleaning each vent and duct run individually, and a final walkthrough. It takes time to do it correctly, and that’s time well spent for your air quality and system efficiency.
Not if it’s done correctly. We use negative air pressure and seal off vents to keep dust and debris contained during the cleaning process. Everything gets pulled directly into the vacuum system, not blown around your house. Our technicians wear booties, use drop cloths, and treat your home with respect. After we’re done, your home should be just as clean as when we arrived—cleaner, actually, because the air circulating through your vents will be free of all that built-up dust and debris.
It’s not a scam when it’s needed and done right, but the industry does have its share of dishonest operators. The EPA says routine cleaning isn’t necessary for most homes. However, if you have visible mold in your ducts, a rodent or insect infestation, ducts clogged with dust and debris, or you’ve just finished a renovation, cleaning makes a real difference. The key is working with someone who’ll assess your system honestly and tell you what you actually need, not just try to make a sale. That’s how we operate.
A complete cleaning covers your entire HVAC system, not just the ducts. That means supply and return air ducts, all registers and grilles, the blower motor and fan, the air handler, and heating and cooling coils if accessible. We start with a visual inspection, often using cameras to see inside the ductwork. Then we use powerful vacuum equipment to create negative pressure while brushing and agitating debris loose from every surface. Finally, we do a post-cleaning inspection so you can see the difference. Anything less than that is cutting corners.
