Air Duct Cleaning Company in St. Andrews, SC
When ducts in St. Andrews start leaking, sagging, or pulling attic air into the supply side, the fix is air duct repair, not another pass with a vacuum. This page is for homeowners and property managers in this Columbia suburb who suspect their duct system is the reason a room never cools right or why the house smells musty by June. St. Andrews sits in the Midlands’ humid subtropical belt, where the HVAC system runs from roughly March through October and the ductwork spends most of the year cool and damp. We’re Hartwell Air Duct Cleaning, and we troubleshoot duct integrity with professional-grade equipment. Call (866) 942-9804 for a free estimate on duct repair in St. Andrews.
Why St. Andrews Homes Are Different
Duct work in St. Andrews deals with an older housing stock under a long cooling season. The suburb is dominated by mid-century and late-20th-century single-family ranches and split-levels, and many of them still run original or partly retrofitted rigid and flex duct systems that are now 30-50 years old. In homes where flex duct runs through an unconditioned attic, years of heat cycling leave those runs sagging, crushed, or pulled loose at the collar. The climate makes it worse. Columbia’s long, hot, humid summers keep duct interiors cool and damp for most of the year, which is exactly the condition mildew needs. Heavy spring pine pollen and red clay dust drawn off the surrounding Midlands landscape settle into the return side. This is why so many St. Andrews calls are less about winter dust and more about musty odors and mold growth that build up during the cooling season.

Our Main St. Andrews Services
Two jobs come up again and again in this suburb: cleaning out the ducts and dryer vent, and repairing the duct runs that have failed behind the drywall and in the attic. Here’s what each involves here.
Air Duct Cleaning in St. Andrews
A typical duct cleaning in St. Andrews starts with the return side, where red clay dust and spring pine pollen collect fastest. We use contact cleaning with Rotobrush and negative-pressure capture with Nikro, then pull the debris out of the system rather than stirring it into the rooms. In the older ranches, that often means cleaning around sagging flex runs before we evaluate whether the duct itself needs repair. If your ducts haven’t been serviced since the house changed hands, Air Duct Cleaning in St. Andrews lays out the process, the equipment we bring, and what a whole-system clean covers.
Dryer Vent Cleaning in St. Andrews
The dryer vent is the other part of the air pathway we service in St. Andrews, and in older homes it’s frequently the one nobody has looked at. Lint builds up in the run, especially where the vent travels through an exterior wall or a long attic path, and that restricted airflow makes the dryer work harder and run longer. We clear the full length of the vent and confirm the exhaust moves freely. Dryer Vent Cleaning in St. Andrews covers what the service includes and the signs it’s overdue.
Air Duct Repair in St. Andrews
Air duct repair in St. Andrews is mostly about ductwork that was installed decades ago and has been quietly degrading ever since. In the ranch homes here, technicians routinely find flex duct runs crushed or disconnected in the attic after years of heat cycling, which pulls hot attic air and insulation fibers straight into the supply side. The failure tends to peak in the first 100-degree weeks of summer, when the system finally runs hard enough to reveal it. Repair is a separate job from cleaning, and it’s one we handle in-house – see Air Duct Repair for the full picture of what we fix.
Ductwork Repair
Signs you need it
You know ductwork repair is due when one room runs warm while the rest of the house cools fine, or when you can see crushed, torn, or disconnected runs in the attic.
What it costs in St. Andrews
Ductwork repair in St. Andrews typically runs $250-$600 depending on how many connections and how much flex needs resealing or re-hanging, with the written estimate setting the final figure.
How we do it
We inspect the accessible runs, reconnect and re-seal the failed joints with mastic and tape, re-support sagging flex, and confirm airflow at the registers before we leave.
Air Duct Replacement
Signs you need it
Replacement makes sense when the duct itself is beyond repair, with flex that’s collapsed along most of its length, torn open at the collar, or soaked through with condensation and mildew from the long cooling season.
What it costs in St. Andrews
Air duct replacement in St. Andrews usually falls in a typical range of $1,200-$3,500 depending on the number of runs and how much attic access the job requires, with the estimate fixing the price.
How we do it
We measure the existing layout, remove the failed duct, install new runs sized for the system, seal every joint, and test airflow at each register once the system is back online.
What Air Duct Repair Costs in St. Andrews
These are typical ranges for the St. Andrews market, priced per system rather than per vent. The written estimate sets the final number.
| Item | Typical range in St. Andrews |
|---|---|
| Ductwork repair (reseal, reconnect, re-support) | $250-$600 |
| Air duct replacement (per system) | $1,200-$3,500 |
| Full duct inspection and airflow test | $150-$350 |
Can duct repair fix a room that never cools right?
Often, yes. A room that stays warm while the rest of the house cools is a classic sign of a disconnected or crushed supply run pulling hot attic air. Repairing that run restores balanced airflow. Call (866) 942-9804 for an exact quote – estimates are free.
Will repair cost more if the attic access is tight?
It can, because access shapes how much labor the job takes. Attics in the older St. Andrews ranches vary a lot in clearance and walkability, so the estimate reflects what we can actually reach. Call (866) 942-9804 for a free estimate.
Brands We Service in St. Andrews
We work comfortably with the air-quality brands your system depends on, including Honeywell and Aprilaire for the filtration and control side, and Nikro and Abatement Technologies for negative-pressure and abatement-grade capture. We don’t claim to stock parts for them; we clean and repair the ductwork these systems rely on. Turnaround depends on the scope of the estimate. See our brands.

What St. Andrews Customers Say
"They photographed every return and supply before starting and sent me the file afterward. No upsell to a sanitizing treatment I didn't need."
- Shanice Boyd"Found a disconnected run in the crawlspace while they were in there and told me about it rather than cleaning around it."
- Ebony Hampton"My wife's allergies had been bad in this house since we moved in. It's been two months since they did the ducts and it's noticeably better. Not a miracle, but real."
