When did you last think about the air inside your home?
Most homeowners don’t — until something feels off. A stale smell. Allergies that won’t quit. Dust reappearing on furniture days after cleaning. Your duct system is the lungs of your home, and what’s inside it is circulating through your air 5 to 7 times every day.
According to the U.S. Environmental Protection Agency, indoor air can be 2 to 5 times more polluted than the air outside. In most homes, the duct system is a significant reason why.
Do You Actually Need It?
How do you know if your ducts need cleaning?
Here are the situations where duct cleaning delivers the most meaningful improvement:
- Pets in the home — Dander and hair settle deep into ductwork beyond what any filter captures, and recirculate continuously.
- Allergies or asthma — If symptoms are consistently worse indoors, your duct system may be the source.
- You’ve never had it done — Most duct systems haven’t been cleaned since the home was built. What’s accumulated over 10, 20, or 30 years may surprise you.
- Recent renovation or remodel — Drywall dust, sawdust, and construction debris embed themselves in ductwork and circulate for months afterward.
- Musty or stale odors when the system runs — This often signals mold, mildew, or biological growth inside the duct system — not just a surface smell.
- Rising utility bills with no clear cause — Debris buildup restricts airflow, forcing your system to run longer and work harder to hit the same temperature.
- You moved into the home — You don’t know what the previous owners had: smokers, pets, neglected maintenance. A cleaning gives you a clean start.
- Elderly family members, young children, or infants — Developing lungs and compromised immune systems are more sensitive to indoor air quality than most people realize.
It’s simply been 3 or more years — For most households, cleaning every 3 years is appropriate. If you have pets, allergy sufferers, or heavy system use, every 2 years is a better interval.
How We Do It
Professional-grade equipment. A process you can see.
Many duct cleaning companies use a shop vacuum and a brush.
Our process uses professional-grade negative air machines — the same industrial equipment used in mold remediation and restoration work. These units draw air through a true HEPA filtration system that captures 99.97% of particles down to 0.3 microns, including mold spores, fine dust, bacteria, and allergens. Contaminated air is captured and filtered — not just moved around.
Here’s what a Goff cleaning includes:
- Video inspection before we start — We use advanced camera equipment to show you exactly what’s inside your ducts before we touch anything. You see what we see.
- Brush and negative air extraction — We systematically clean trunk lines, branch lines, supply vents, and return lines using professional-grade brushing equipment combined with HEPA-filtered negative air pressure, pulling debris out rather than pushing it further in.
- Blower compartment service — Depending on your package, we clean the blower compartment and cabinet where debris concentrates and affects system performance.
- EPA-approved sanitizing treatment — After cleaning, we apply an EPA-approved antimicrobial sanitizer to address biological growth and leave your system clean at the source.
After inspection and documentation — We show you the results before we leave. You’ll see the difference.
Most duct cleaning companies know how to clean a duct. Our technicians know how they’re built. Goff installs HVAC systems from the ground up — and that hands-on experience gives our team a depth of familiarity with ductwork that a cleaning-only specialist simply doesn’t have. And if we find something that warrants a closer look, a full HVAC evaluation is one call away — with the same company.

Dryer Vent Cleaning
Dryer Vent Cleaning
Don’t forget your dryer vent.
The U.S. Fire Administration identifies lint buildup as the leading cause of residential dryer fires. While we’re in your home, adding a dryer vent cleaning is an easy decision — same visit, and it takes 30 minutes or less.
Signs your dryer vent needs cleaning: clothes taking more than one cycle to dry, the dryer running hot to the touch, or it’s been more than a year since the last cleaning.
How Often?
How often should you have your ducts cleaned?
The National Air Duct Cleaners Association (NADCA) recommends every 3 to 5 years for most homes. We recommend every 3 years as a standard interval, and every 2 years for homes with pets, allergy sufferers, smokers, or high system usage. If you’ve never had it done — regardless of when you moved in — now is the right time.
Schedule a duct cleaning inspection and we’ll show you exactly what’s in your system before we start. No pressure. No surprises. Just honest work from a local team that’s been serving Northern Indiana since 1937.
