How Can I Seal a Leaking Air Duct to Improve HVAC Efficiency?

To improve HVAC efficiency when ducts are leaking, start with a professional duct assessment and cleaning. Clean ducts keep air flowing without hindrance and help your system retain its energy-efficiency potential. We clean and sanitize using high-pressure air and a high-static vacuum. After the assessment, a technician will review repair options for any leak points and confirm costs on site. Service available across Warrenton, Ashburn, and nearby towns.

Quick checks:

• Dirt around supply or return vents
• More dust in rooms than usual
• Air filter clogging faster
• Signs of rodent activity
