Duct Services in Myrtle Beach, SC

Hot and cold rooms, weak airflow, and dust from the vents usually mean the ducts — not the AC. We test your ductwork, find the actual leaks, and fix them.

How it works

What happens during a duct service visit

1. Airflow and leakage check

We measure room-by-room temperatures and airflow, then inspect accessible duct runs for disconnections, crushing, and failed insulation — with photos you can see.

2. Targeted repair plan

Seal versus replace, section by section. You get a written scope showing exactly which runs we touch and why — no whole-system scare tactics.

3. Seal, repair, and verify

Mastic-sealed connections, replaced sections, reinsulated runs, rebalanced dampers — then we retest airflow to prove the fix worked.

Local expertise

Why ductwork is different on the Grand Strand

Attics here are ductwork's worst enemy. Summer attic temperatures soar, so every leak and every inch of missing insulation is punished immediately — cooled air escaping into the attic, and superheated attic air infiltrating through return leaks. Flexible duct, the most common type in local homes, kinks and crushes easily when homeowners store boxes on top of it, and the humid air slowly degrades old insulation wrap.

Salt air finds the metal too: rusted takeoffs, plenums, and straps in oceanfront homes. Renovations are another local pattern — a flipped Surfside bungalow or a remodeled Pawleys kitchen where a run got cut and never properly reconnected. And in flood-zone homes with elevated equipment, we see duct transitions that were never sealed after the lift. Every duct job here starts from what the coast did to the system, not from a generic checklist.

Common problems

Duct problems we fix most on the Strand

One room never cools while the rest are fine

Our fix Our fix: we trace that run — usually a crushed, kinked, or disconnected flex duct, or a missing return. Targeted repair beats a new AC every time here.

High bills even with a newer system

Our fix Our fix: leaky ducts can waste a large share of conditioned air into the attic or crawl space. We test leakage, mastic-seal it, and the system finally delivers what you paid for.

Dust puffing from vents

Our fix Our fix: supply leaks pull dusty attic or crawl-space air into the airstream. Sealing the leaks plus proper filtration ends the dust cycle.

Ducts sweating in summer

Our fix Our fix: failed insulation plus humid air equals condensation — which drips, stains, and grows mold. We reinsulate and seal so the duct surface stays above the dew point.

Pricing

What affects the cost of duct work

Duct jobs range from sealing a few connections to full replacement. The drivers:

  1. Accessible vs. buried runs: Open attic ducts are quick to reach; ducts buried under insulation or in tight crawl spaces take longer.
  2. Seal vs. replace scope: Mastic-sealing existing ductwork costs less than replacing collapsed or mold-damaged sections — we recommend based on condition, not commission.
  3. Linear footage and fittings: Total duct length, number of takeoffs, and plenum condition set the material and labor scope.
  4. Insulation level: Rewrapping to a proper R-value in a hot attic adds material cost but cuts energy waste year-round.

FAQs

Duct service FAQs

How do I know if my ducts are leaking?

Classic signs: rooms that never get comfortable, unusually high bills, dusty vents, and ducts in the attic that look crushed or disconnected. We confirm with airflow and leakage testing.

Should I seal my ducts or replace them?

Seal when the duct material is sound and the problem is connections and leaks. Replace when flex duct is crushed, insulation has failed throughout, or there is mold damage. We show you photos and recommend accordingly.

How long does duct sealing take?

Most single-family sealing jobs finish in a day. Full replacements or difficult crawl-space work can take longer — your written scope states the timeline.

Will fixing my ducts lower my energy bills?

Sealing significant leaks means the system delivers the air you already paid to condition instead of losing it to the attic. Most homeowners notice both comfort and bill improvements.

Do you work in attics and crawl spaces?

Yes — that is where the ducts live. We photograph everything we find so you can see the before and after without climbing up yourself.

24/7 emergency line

Vents blowing weak — or not at all?

A disconnected main trunk or a failed blower can take a whole zone down at once. Call and we will get airflow restored, then fix the underlying duct problem. Call (123) 456-789 any time, day or night.
