FAQs
Why is duct cleaning important for my Cowan home?
Over time, dust, pollen, pet dander, and even mold spores can accumulate inside your ductwork. Cowan’s humid summers and cool winters mean your HVAC system runs most of the year, constantly circulating whatever is inside the ducts. Professional cleaning removes these contaminants, which helps improve indoor air quality, reduces allergy triggers, and allows your heating and cooling equipment to operate more efficiently.
How often should I schedule duct cleaning with Mountain-Fresh Air Heating & Air Conditioning?
For most Cowan households the National Air Duct Cleaners Association (NADCA) recommends a thorough duct cleaning every 3–5 years. However, you may need service sooner if you’ve recently completed a renovation, have shedding pets, notice visible dust blowing from vents, or suffer from unexplained allergy or respiratory issues. We’re happy to perform a free inspection and let you know if cleaning is warranted now or can safely be postponed.
What happens during a Mountain-Fresh Air duct cleaning appointment?
1. Inspection: Our certified technicians open access panels and use a video scope to examine the condition of your supply and return ducts. 2. Containment: We protect floors and furnishings, then attach a high-powered negative-pressure vacuum to the trunk line to keep debris from escaping into your living space. 3. Agitation & Extraction: Rotating brushes and compressed-air whips dislodge buildup while the HEPA-filtered vacuum collects it. 4. Sanitizing (optional): If we detect microbial growth, we can apply an EPA-registered disinfectant. 5. Final Report: You’ll see before-and-after images and receive suggestions for maintaining clean, healthy ducts.
Do I need to do anything to prepare my house before the technicians arrive?
Just make sure we have clear access to supply and return vents, the furnace or air-handler, and the main trunk lines (usually in a basement, crawl space, or attic). Remove fragile items from the work area, secure pets, and plan for each zone of the home to be offline for 2–4 hours. We bring protective coverings and will leave your home exactly as we found it—only cleaner.
Can duct cleaning lower my energy bills?
Yes. When ducts are coated with debris, the blower motor has to work harder to push air through the system, which increases electricity or gas usage. The U.S. Department of Energy estimates that 25–40 % of the energy used to heat or cool a home is wasted in dirty or poorly maintained systems. After cleaning, many Cowan customers report noticeably stronger airflow and lower monthly utility costs, especially during peak summer heat and winter cold snaps.
How much does professional duct cleaning cost in Cowan and what factors affect the price?
Pricing typically ranges from $350 to $650 for an average single-family home in the Cowan area. Variables include the size of the home, number of HVAC zones, accessibility of ductwork, level of contamination, and whether optional services like antimicrobial treatment or dryer-vent cleaning are added.
