Question 1

What is duct sealing?

Accepted Answer

Duct sealing is the process of closing leaks in a home's duct system so more of the air your HVAC equipment conditions actually reaches the rooms it was intended for. Duct systems leak at connections, seams, boots, plenums and damaged sections. Sealing addresses those openings so conditioned air stops escaping into attics, crawlspaces, wall cavities and other unconditioned areas.

Question 2

How do I know if my ducts leak?

Accepted Answer

You usually cannot tell by looking. Common signals include rooms that never get comfortable, weak airflow at certain registers, a system that runs for long stretches, and dust or temperature complaints that do not match how new the equipment is. The reliable answer comes from measurement: we test the duct system and establish how much leakage exists before any work is proposed.

Question 3

Can duct leakage cause uneven temperatures?

Accepted Answer

It can contribute. When a portion of the conditioned air escapes before it reaches a room — or when leakage on the return side pulls in air from an attic or crawlspace — the rooms furthest from the air handler often suffer first. Duct leakage is one of several possible causes of uneven temperatures, which is why we measure rather than assume.

Question 4

Can ducts in an attic be sealed?

Accepted Answer

Attic duct systems are one of the most common systems we evaluate in Southeast Louisiana. Whether a specific system can be sealed effectively depends on its condition, design and accessibility, which the evaluation is designed to determine.

Question 5

Do you have to tear open my ceiling or walls?

Accepted Answer

Often no. Some duct leakage can be addressed without extensive demolition. That said, it would be dishonest to promise it in every case: badly damaged, disconnected or improperly designed sections may require physical access, repair or replacement. We tell you what we find before work begins.

Question 6

How long does duct sealing take?

Accepted Answer

Most residential projects are completed in a single visit, including the before-and-after testing. Larger homes, multiple HVAC systems and difficult-to-access duct systems take longer. We give you a time estimate after the evaluation, not before we have seen the system.

Question 7

Can duct sealing reduce energy consumption?

Accepted Answer

Reducing duct leakage means less conditioned air is lost to unconditioned space, which can reduce how hard and how long your HVAC system has to work. We do not guarantee a specific savings percentage. Actual results depend on your duct system, equipment, home construction, thermostat habits, weather and utility rates. What we can do is document the measured change in duct leakage.

Question 8

Should ducts be evaluated before replacing an HVAC system?

Accepted Answer

It is worth considering. New equipment is connected to the existing duct system in many replacements. If that duct system leaks, some of what the new equipment produces can still be lost before it reaches the rooms. Evaluating the ducts first gives you and your HVAC contractor better information.

Question 9

Can Duct Daddy work with my HVAC contractor?

Accepted Answer

Yes. We work as a specialty third-party duct-sealing provider alongside HVAC companies. The customer relationship stays with the contractor; we handle the duct-sealing scope.

Question 10

Do you perform before-and-after testing?

Accepted Answer

Where applicable, yes. We measure duct leakage before the work, seal the system, then test again and document the measured difference. We do not just say your ducts are tighter.

Question 11

Does duct sealing replace duct replacement?

Accepted Answer

No. Sealing addresses leakage. It does not correct crushed, collapsed, disconnected, undersized or improperly designed ductwork, and it is not a substitute for repair or replacement when a system is in poor condition. Some duct systems need modification or replacement rather than sealing alone, and we will tell you when that is what we find.
