FAQs
How often should I schedule professional duct cleaning for my HVAC system in Kelso?
For most Kelso homeowners, we recommend scheduling a thorough duct cleaning every 3–5 years. The exact interval can vary based on factors such as the age of your home, presence of pets, smokers in the household, recent remodeling projects, or allergy sensitivities. Our technicians will inspect your ducts and provide a personalized recommendation during your service call.
What signs indicate my air ducts need cleaning?
Common indicators include noticeable dust around supply registers, musty or stale odors when the HVAC system runs, unexplained respiratory or allergy flare-ups, inconsistent airflow in certain rooms, and visible mold growth inside the ductwork or on HVAC components. If you experience any of these issues, book an inspection to confirm whether duct cleaning is warranted.
Will duct cleaning improve my indoor air quality and HVAC efficiency?
Yes. Removing built-up dust, pollen, pet dander, and microbial growth from your ducts helps reduce airborne contaminants, which can alleviate allergy and asthma symptoms. Clean ducts also promote smoother airflow, allowing your furnace and air conditioner to operate more efficiently, potentially lowering energy bills and extending equipment life.
How long does a typical duct cleaning visit take, and will it disrupt my day?
An average single-family home in Kelso takes 2–4 hours to complete, depending on square footage, number of vents, and level of contamination. Our crew uses negative-pressure vacuums and rotary brush systems that keep dust contained, so you can remain in your home with minimal disruption. We protect floors and furnishings, and we’ll review results with you before leaving.
Is duct cleaning safe for my HVAC system and environmentally friendly?
Absolutely. We follow National Air Duct Cleaners Association (NADCA) standards, using soft-bristle rotary brushes and HEPA-filtered vacuums that won’t damage duct surfaces or HVAC components. We avoid harsh chemicals; if antimicrobial treatment is needed, we use EPA-registered, low-VOC products safe for people, pets, and the environment.
What does your duct cleaning service in Kelso include and how much does it cost?
Our package includes a pre-cleaning inspection (with camera footage), sealing of supply and return registers, negative-pressure vacuuming of the entire duct network, rotary agitation to dislodge debris, cleaning of the blower, evaporator coil, drain pan, and final system sanitization if requested. Pricing starts around $425 for an average 1,800-sq-ft home, with a firm quote provided upfront after inspection. We also offer discounts when bundled with seasonal HVAC maintenance plans.
