Your ductwork is the part of the HVAC system most homeowners never think about — and it's also the part that quietly destroys system efficiency, indoor air quality, and comfort when it's neglected. Leaky ducts in a Carolina crawlspace can waste 25-40% of the conditioned air your system produces, send dust and humidity into rooms, and force the unit to run longer to compensate.
Total Plumbing Pros handles the full range of ductwork: professional duct cleaning, leak testing, mastic sealing, full duct replacement for failing flex lines, new duct runs for additions, and Aeroseal-style sealing for hard-to-reach systems. Healthier air, lower bills, longer system life.
Signs You Need Ductwork & Duct Cleaning
Visible Dust at Vents
Dust caking on supply registers or visible debris blowing out of vents means contaminated ducts feeding allergens directly into your living space.
Uneven Temperatures Between Rooms
Rooms that never cool or heat correctly often have crushed flex duct, disconnected boots, or major leaks robbing them of airflow.
Higher-Than-Normal Bills
Leaky ducts in unconditioned crawlspaces and attics waste 25-40% of system output. Sealing them can cut HVAC bills 15-25% immediately.
Allergy or Asthma Symptoms Indoors
Mold, pet dander, construction dust, and rodent debris in old ducts blow through the house every time the system runs. Cleaning and sealing fixes it.

Our Process
- 1
Inspection & Quote
We inspect the supply, return, and main trunk lines, check for leaks, crushed flex, and contamination, then quote a flat price.
- 2
Sealing & Containment
We seal off vents and create negative pressure inside the duct system so all dislodged debris pulls into our containment vacuum — not into your home.
- 3
Cleaning & Sealing
Rotating brushes and compressed air dislodge buildup while the HEPA vacuum pulls it out. Joints and boots are then sealed with UL-181 mastic.
- 4
Final Walk-Through
We show before/after photos, confirm airflow at every register, and provide a written record of work performed.
Industry Standards & Resources
Our ductwork & duct cleaning work follows the standards published by these national authorities:
We don't use the gas-station 'duct cleaning' specials that just spin a brush at the register and call it done. Total Plumbing Pros uses true negative-pressure cleaning with HEPA containment and proper mastic sealing — the way the EPA, NADCA, and ENERGY STAR all specify it.
