FAQs

Why is air duct cleaning important for my HVAC system in Johnson City?

In Johnson City’s humid summers and cool winters, dust, pollen, and moisture can accumulate in ductwork, promoting mold growth, circulating allergens, and forcing your HVAC system to work harder. Professional duct cleaning removes these contaminants, helping your equipment run more efficiently, extending its lifespan, and improving indoor air quality year-round.

How often should I have my ducts cleaned?

For most Johnson City homes, the National Air Duct Cleaners Association (NADCA) recommends a full duct cleaning every 3–5 years. However, you may need more frequent service if you have pets that shed, residents with allergies or asthma, recent remodeling projects, or if you notice visible dust buildup or musty odors coming from vents.

What signs indicate my ductwork needs cleaning?

Common red flags include visible dust or debris blowing from supply vents, musty or moldy odors when the HVAC cycles on, unexplained respiratory irritation, uneven airflow, higher-than-normal utility bills, and recent water leaks or pest infestations inside the ductwork.

What does your duct cleaning process involve?

Our certified technicians begin with a camera inspection to pinpoint trouble spots. We then attach a high-powered negative-air vacuum to the main trunk line, isolating each branch with access tools. Agitation devices—such as rotating brushes and compressed-air whips—dislodge debris, which is pulled into a HEPA-filtered containment system. We finish by sanitizing the ducts (upon request) and replacing the HVAC filter to ensure a clean, sealed system.

Will duct cleaning really improve energy efficiency and indoor air quality?

Yes. Removing buildup allows conditioned air to move freely, reducing the strain on motors and blowers, which can cut energy consumption by up to 20 %. Cleaner ducts also reduce recirculation of dust, mold spores, pet dander, and other allergens, leading to fresher air and fewer respiratory issues for occupants.

How long does a typical duct cleaning service take and what does it cost in Johnson City?

A standard single-family home with one HVAC system usually takes 2–4 hours to clean. Larger homes or those with multiple units may require a full day. Pricing in Johnson City generally ranges from $350 to $600 per system, depending on square footage, number of vents, contamination level, and optional services like antimicrobial treatments or dryer-vent cleaning.
