Creating a Healthier Home with Professional Duct Cleaning
Air ducts play a bigger role in your comfort than many homeowners realize. Over time, dust, pollen, pet dander, and other airborne particles can collect inside the system, gradually affecting both efficiency and indoor air quality. In Louisville, Evansville, and across Kentuckiana, where seasonal changes bring a variety of allergens, keeping your ductwork clean can make a noticeable difference in how your home feels and functions.
Professional duct cleaning helps ensure that conditioned air flows freely through your system, reducing the strain on your HVAC equipment and allowing it to operate more efficiently. That can translate to lower energy bills, fewer breakdowns, and a longer lifespan for your heating and cooling system. It also means the air circulating in your home is cleaner, fresher, and healthier to breathe.
Scheduling a cleaning with an experienced team ensures the job is done thoroughly and safely, using the right equipment to remove debris without damaging your ducts. With proper care, you can enjoy the benefits of improved air quality, a more efficient HVAC system, and a cleaner living space for months to come.

Duct Cleaning FAQ’s
Do you clean both supply and return ducts?
Yes. The two sides are different: The supply ducts send air throughout your house, and the return ducts bring air back into your HVAC system. Both need professional cleaning.
How do I know if my ducts have mold? What can be done about it?
Unfortunately, moisture and mold thrive in Kentuckiana homes. Mold is a contamination that poses health hazards, so don’t ignore the signs you have mildew or mold in your HVAC ducts:
A mushroomy, mildew-like odor when your heating or cooling cycle kicks on is likely a mold problem. It can occur in one room or your entire home.
Increased allergy or asthma symptoms are associated with mold in ducts.
Inspect vents, walls, and flooring regularly for signs of mold. Moisture or stains on your ceilings and floors could be a structural or ductwork problem. (Some homeowners report upholstered furniture begins to feel damp.) If you see black, brown, green, or yellow growth on air vents, it’s likely a mold issue.
How often should I have my ducts cleaned?
You should vacuum and clean your vents every year. If your vents become dust-covered more often, that’s a sign you need professional duct cleaning. You can’t effectively DIY ductwork cleaning. The National Air Duct Cleaners Association recommends cleaning every three to five years.
Is duct cleaning necessary if I have a new HVAC system?
If you’re replacing an older HVAC system, it’s the perfect time to replace or clean air ducts. Even if you have a new home, dirt and airborne debris can linger in your ductwork after construction, so duct cleaning is recommended.
How long does professional duct cleaning take?
Most single-family homes take about two to four hours, depending on home size, number of registers, contamination level, and access. Technicians protect floors, create negative pressure on the system, agitate debris with rotary brushes or air whips, vacuum with HEPA filtration, clean registers and plenums, and verify airflow before they finish.
What methods and equipment do professionals use?
Reputable providers use a combination of negative-air vacuum equipment, sealed hoses, and mechanical agitation (rotary brushes or air whips) to dislodge debris, followed by capture with high-powered, HEPA-filtered vacuums. Supply, return, and trunk lines are addressed end to end. If there’s confirmed microbial growth or persistent odor sources, an optional post-cleaning treatment may be recommended—only after mechanical cleaning and with products appropriate for HVAC use.

What Are the Benefits of Professional Duct Cleaning Services in Louisville, KY, and Surrounding Areas?
Experience cleaner air, improved comfort, and enhanced energy efficiency with professional duct cleaning in Louisville, KY and the surrounding areas from A+ Derr Heating & Cooling, your local HVAC company you can trust. Regular duct cleaning is an essential part of any HVAC maintenance plan, helping your furnace, heat pump, or air conditioner last longer and perform better. Accumulated dust, allergens, pet dander, and debris inside ducts over time can clog the system and block airflow, but professional duct cleaning will restore air movement for healthier, more comfortable indoor air.
1. Improves Indoor Air Quality
Clean air ducts circulate cleaner air throughout your home. Dust, pollen, mold spores, pet dander, and other contaminants that can aggravate allergies, asthma, or respiratory problems are reduced when the ducts are professionally cleaned. Cleaning ducts is especially important in Louisville’s humid climate which is more prone to mold growth inside ductwork.
2. Enhances HVAC Efficiency
A build-up of dust, debris, and contaminants inside ductwork causes the HVAC system to work harder to circulate air. With professionally cleaned ducts, the system can move air more easily to improve overall airflow. This allows the heating and cooling system to run more efficiently, which lessens wear and tear and reduces monthly energy costs.
3. Reduces Dust and Odors in the Home
Are you finding that dust accumulates quickly after cleaning or that strange odors linger when you turn on the heating or cooling system? One or both of these problems can be caused by dirty ducts. The accumulated particles that get trapped in the ducts over time release dust and mildew into the home when the system is on. Professional duct cleaning can help to remove these particles and odors, keeping your home fresher and cleaner for longer.
4. Extends the Life of HVAC Equipment
Regular duct cleaning as part of an HVAC maintenance plan can help to extend the life of the heating and cooling system. By improving airflow and circulation, the system experiences less strain and wear on internal parts. Less dust and debris on components also means less clogs, cleaner coils, and less risk of early motor or fan failure.
5. Supports Healthier, More Comfortable Living
Clean ducts more evenly distribute conditioned air throughout the home, which helps reduce hot or cold spots as well as excessive humidity. Families with kids, elderly family members, or pets are the most likely to benefit from professional duct cleaning as part of a routine maintenance plan.
Local tip: Humidity, seasonal pollen levels, and an aging housing stock all make duct cleaning in Louisville, KY an especially good idea every 3 to 5 years, or more often if you’ve recently remodeled, gotten rid of shedding pets, or seen visible dust accumulation.
In summary:
Professional duct cleaning in Louisville, KY, and nearby areas can help homeowners to achieve lower energy costs, longer-lasting HVAC equipment, and cleaner, healthier air indoors for their families.
