Duct Sealing
Duct Sealing in St. George
In homes with forced-air heating and cooling, leaky ducts quietly waste a large share of the air you pay to condition. Sealing them fixes that.

In plain terms
What duct sealing is
In houses with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. Over time those ducts develop leaks, holes, and poorly connected joints.
About 20 to 30 percent of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts. Duct sealing closes those gaps so the air your system conditions actually reaches the rooms it is meant for.

Why duct sealing matters
When 20 to 30 percent of conditioned air never reaches the room, the system runs longer to make up for it. Sealing the ducts puts that air — and that cost — back where it belongs.
- 20-30%
- Of the air moving through a duct system is typically lost to leaks.
- Even rooms
- More consistent temperatures from room to room.
- Less runtime
- The system works less to reach the temperature you set.

Common questions
Duct Sealing questions, answered
A few of the questions homeowners ask most about this service. The full list lives on our FAQ page.
How much air do leaky ducts really waste?
In a typical forced-air home, about 20 to 30 percent of the air moving through the duct system is lost to leaks, holes, and poorly connected joints. That is air you have already paid to heat or cool, escaping before it ever reaches the room it was meant for.
“They were professional and up front about our attic insulation and duct repair. They were on time and the work was completed efficiently.”
What are the signs my ducts are leaking?
Common signs are rooms that never match the thermostat, a system that runs longer than it should, rising energy bills, and dust that keeps coming back. Sealing the duct runs puts that lost conditioned air — and that cost — back where it belongs.
“They showed up right when they said they would, completed the work quickly, and cleaned up afterward. Would use them again.”
Is duct sealing the same as duct cleaning?
No. Duct cleaning removes dust and debris from inside the ducts. Duct sealing closes the leaks, holes, and loose joints that let conditioned air escape. They address different problems — sealing is about keeping the air you paid for inside the system.
“They listened to my concerns, discussed the pros and cons, and recommended what they would do as if they were working on their own home.”
