A surprising share of a home's conditioned air never reaches the vents at all — it escapes through leaky duct joints in the attic or crawlspace.
Mastic sealing, not just tape, for joints that actually need to last.
If you're dealing with one room that never quite reaches temperature, unusually high utility bills relative to system size, or visible disconnected duct runs discovered in the attic, you already know leaky or poorly balanced ductwork can waste a significant share of a system's output before it ever reaches a single vent, and most homeowners never know to check.

Most ductwork repair problems give some warning before they turn into one room that never quite reaches temperature, unusually high utility bills relative to system size, or visible disconnected duct runs discovered in the attic — catching it early usually means a shorter, cheaper fix.
AAA Pro HVAC built its ductwork repair process around one idea: diagnose first, quote honestly, fix it right.
We're licensed, insured, and staffed with techs who've spent years specifically on ductwork repair, not general handyman work with an HVAC certificate bolted on.

We use pressure testing equipment to quantify actual duct leakage rather than sealing wherever looks suspicious.
Every sealed joint is inspected after curing, not just applied and left.
We adjust dampers and measure room-by-room airflow after sealing, not just at the trunk line.
We measure static pressure before and after work to confirm the fix actually improved performance.
From the first symptom to the final fix, these are the specific ductwork repair services our Lamar-area crews are equipped for.
Pressure testing locates leaks precisely instead of sealing every joint indiscriminately. Techs handling duct leak detection & sealing carry the specific parts and tools this job calls for, not a generic kit.
Fully disconnected sections in an attic or crawlspace can dump conditioned air directly outside the living space. This is one of the most requested ductwork repair calls we get across Lamar, SC.
Room-by-room airflow measurement identifies which zones are starved and which are over-supplied. This is one of the most requested ductwork repair calls we get across Lamar, SC.
We match insulation R-value to the space's conditions. Techs handling duct insulation repair & replacement carry the specific parts and tools this job calls for, not a generic kit.
A return duct too small for the system's airflow requirement creates constant static pressure problems system-wide. This is one of the most requested ductwork repair calls we get across Lamar, SC.
High static pressure strains the blower motor and shortens its life; low pressure means air isn't moving efficiently. This is one of the most requested ductwork repair calls we get across Lamar, SC.

Describe the symptom — uneven room temperatures, high bills, or a suspected disconnected run — and we route accordingly.
We inspect accessible duct runs thoroughly, not just at the visible trunk line.
Flat-rate quote reflects the confirmed scope of repair needed.
We remeasure after the repair to confirm the numbers actually improved.

Bedroom over the garage never got below 80 in summer no matter what.
Utility bills always seemed high for the size of our house.
Genuinely convincing to see the numbers change.
Return duct was undersized the whole time, apparently common in homes our age.

Signs include uneven room temperatures, unusually high utility bills, and visible gaps at duct joints in an attic or crawlspace.
No — despite the name, standard duct tape degrades quickly in attic heat and typically fails within a few years.
Yes — conditioned air lost through duct leaks before reaching the vents is effectively paid-for air that never does its job.
A leak physically loses air before it reaches the vent; a balancing problem means air reaches the vents but unevenly across rooms.
That's typically where the most significant leaks and disconnections are found.
Non-emergency duct inspections are scheduled based on current demand across Lamar, SC.

Our ductwork repair crews are positioned throughout Lamar, SC to keep response times realistic, not just promised.
