Is HVAC Duct Cleaning Really Worth the Money in San Jose, CA?

Many homeowners in San Jose question whether HVAC duct cleaning is a necessary service or an unnecessary expense. After working on California homes for over 15 years, I can say the value depends entirely on the condition of your duct system and indoor air quality issues. In 2026, rising energy costs and ongoing wildfire smoke exposure make this decision more relevant for Bay Area homeowners.

• Heavy dust or debris buildup inside ducts
• Wildfire smoke residue, common in California homes
• Recent construction or remodeling
• Pet hair and dander accumulation
• Leaky ductwork pulling air from attics or crawl spaces
• Older duct systems common in San Jose housing
