Frequently Asked Questions (FAQ)
1. How much does air duct cleaning cost in Westminster?
Costs vary depending on home size, number of vents, and system condition, but Westminster homeowners typically spend between $300 and $600 for full-service cleaning. Cheaper “vent-only” offers often skip essential components. Investing in a complete system cleaning ensures contaminants are removed, airflow is restored, and your HVAC operates efficiently for years, making the service cost-effective in the long run.
2. Can duct cleaning remove odors from my Westminster home?
Yes, professional duct cleaning helps eliminate musty, smoky, or chemical smells that circulate whenever the HVAC runs.

Many Westminster homeowners notice immediate improvements in how their home smells after a full-system cleaning is completed.
3. Is duct cleaning safe for older HVAC systems in Westminster?
