Complete Guide to Duct Sealing: Boost Your HVAC Efficiency

At **Red Dragon Heating and Cooling**, we help homeowners tackle this hidden energy drain with professional duct sealing solutions that improve performance, reduce costs, and enhance overall comfort.

## Why Duct Sealing Is Essential
Your duct system acts like the bloodstream of your HVAC setup—delivering warm or cool air to each room. But over time, small gaps, disconnected joints, or cracks in the ductwork can cause 20–30% of that air to escape before it ever reaches its destination.
That lost air forces your HVAC system to work overtime, inflating your energy bills and reducing your comfort. Professional duct sealing can solve this problem quickly and cost-effectively—helping your system operate the way it was designed to.

## Warning Signs Your Ducts May Be Leaking
Wondering if your ducts need attention? These are the most common signs:
– **Uneven room temperatures** despite a consistent thermostat setting
– **Higher-than-usual energy bills** with no major changes in usage
– **Increased dust or allergy symptoms**
– HVAC system running frequently but not effectively heating or cooling your home
These are strong indicators that your ductwork isn’t sealed properly, and that air is being lost in crawlspaces, basements, or walls.

## Our Professional Duct Sealing Methods
At **Red Dragon Heating and Cooling**, we use two main techniques based on your home’s layout and duct accessibility:
### Manual Sealing
We apply a durable mastic sealant or foil-backed HVAC tape to cracks and joints in exposed ductwork—especially in attics, basements, or mechanical rooms.
### Aeroseal Technology
This high-tech option is ideal for duct systems hidden behind walls or ceilings. We inject a fine mist of sealing particles that locate and plug leaks from the inside—sealing even the smallest cracks without tearing into your walls.
