Franzen Heating & Cooling FAQ: air quality

Twice a year is the standard recommendation for servicing commercial HVAC systems -- typically once before the cooling season and once before heating season. High-demand environments like restaurants or server rooms may benefit from more frequent check-ups. Regular servicing ensures performance, prevents breakdowns, and helps maintain indoor air quality for employees and customers.

Yes — removing dust, pollen, mold spores, and other contaminants from your ducts can significantly improve indoor air quality. This is especially helpful for people with asthma, allergies, or other respiratory conditions. Clean ducts mean cleaner air circulating throughout your home.

Common signs include:

• Excessive dust around vents or on furniture
• Allergy or respiratory issues worsening indoors
• Musty or stale odors when the HVAC system runs
• Visible mold or debris inside vents
• Uneven airflow or inconsistent room temperatures

If you notice any of these, it's a good idea to schedule an inspection.
