Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

Storrs isn’t like other Connecticut markets. The university drives a seasonal pulse that shapes what we find in ducts here, and the housing stock splits between century-old New England homes and 1960s – 1980s apartment complexes with original sheet-metal runs. We’ve worked both. We know what fails in each.
Why Hollis Air Duct Cleaning Is Storrs’s Preferred Duct Sealing Company
Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004, and our Hartford office coordinates scheduling for Storrs jobs with the same discipline we apply everywhere: arrive inside the quoted window, price in writing before touching equipment, leave the site clean. Our 365-Day Done Right Promise covers every duct sealing job in writing. If the seal fails within a year, we return and make it right at no charge, including a free second visit.
Our technicians are background-checked and uniformed. You’ll know who’s arriving before they knock. Phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops, no callback queues, no waiting until Monday for a Storrs appointment.

Duct Repair in Storrs
Duct Repair in Storrs means fixing the physical damage we find in aging HVAC systems: reattaching disconnected joints, patching rusted sections, replacing crushed flex runs, and restoring supply and return balance so heated or cooled air actually reaches the rooms it’s supposed to serve. In Storrs, we perform duct repair most often in 1960s – 1980s rentals near UConn where original sheet-metal has corroded from moisture buildup, and in older village homes where decades of debris have hidden collapsed runs behind plaster walls. A typical duct repair in Storrs runs $280 – $650, with larger jobs involving multiple disconnected sections or access through finished surfaces at the higher end.
Disconnected Joints and Rusted Metal
Storrs’s cold winters and humid summers mean HVAC systems run hard year-round. Condensation forms inside ducts, especially in unheated attic spaces common in historic village homes. Over years, this moisture rusts original sheet-metal at the seams. We cut out rotted sections, splice in new material, and seal with mastic rated for temperature cycling.
Crushed Returns Behind Walls
During clean-outs, we feed cameras through ductwork to find returns flattened by settling, renovation damage, or old pest intrusion. In Storrs’s older stock, these runs often sit behind original plaster. We map the damage, explain access options, and quote repair before cutting anything open.
Air Duct Sealing in Storrs
Air Duct Sealing in Storrs closes the gaps, cracks, and seam separations that leak conditioned air into attics, crawl spaces, and wall cavities. We use mastic and reinforced mesh for rigid ductwork, and specialized sealant for flex runs, applied after source removal cleaning so we’re sealing clean metal, not trapping debris. In Storrs, air duct sealing is most needed in rentals with years of student turnover wear, and in historic homes where original ductwork has shifted with building settlement. A whole-home air duct sealing in Storrs typically runs $350 – $850; partial sealing of a single zone or accessible basement trunk line starts around $200.
Post-Cleaning Seal Application
We seal after we clean. That’s non-negotiable. Sealing over dust and debris traps contaminants and guarantees premature failure. Our rotary brush systems and negative-air machines perform source removal first. Then we seal. The result holds.
Supply and Return Balance Testing
After sealing, we measure static pressure and airflow at each register. In Storrs rentals, we often find supply ducts sealed but returns still pulling from unconditioned spaces. We flag it. We fix it. The system works as designed, not as it settled over forty years.
Trusted Brands We Service in Storrs
We carry parts and sealing materials from Aprilaire, Abatement Technologies, and Guardsman, stocked for the Storrs market so we’re not ordering mid-job and making you wait. Aprilaire’s ventilation controls integrate with sealed duct systems to manage humidity, critical in Storrs’s summer months when outdoor moisture loads are high. Abatement Technologies supplies the HEPA filtration and containment tools we use during agitation cleaning. Guardsman provides the mastic and mesh tapes rated for the temperature swings our ducts see. For Storrs homeowners, this means faster turnaround and repairs that match the original equipment specifications.
Common Duct Sealing Problems We See in Storrs Homes
- Rusted original metal in UConn-area rentals. Decades of moisture cycling in 1960s – 1980s sheet-metal ducts near campus leave metal too thin for sealant to bond. We test with a probe. If the metal is gone, we replace the section before sealing.
- Student debris blocking airflow and masking disconnects. Tennis balls, food wrappers, and other items dropped into floor registers during the academic year block returns and hide crushed ducts. Sealing without removing these first traps contaminants and leads to immediate recontamination.
- Unheated attic runs in historic village homes. Ducts routed through freezing attics in winter and humid attics in summer develop condensation that defeats new seals. We address insulation and vapor barriers as part of the sealing plan, not as an afterthought.
- Disconnected joints from building settlement. New England freeze-thaw cycles shift foundations and frame members. Ducts attached to structure separate at the seams. We find these with camera inspection, reattach with mechanical fasteners, then seal.

FAQs About Duct Sealing in Storrs
Student rentals near UConn accumulate debris in registers and develop disconnected joints from heavy year-round HVAC use, so cleaning reveals damage that was hidden by blockage. We find rusted seams, crushed returns, and separated flex connections once the obstruction is removed. Sealing after cleaning fixes the underlying leaks and prevents the same dust from recirculating. Call (361) 326-5060 for an inspection quote.
We find tennis balls, food wrappers, bottle caps, and other items dropped or kicked into registers over the academic year, blocking airflow and masking disconnected duct runs behind them. This pattern repeats every May like clockwork in the Celeron Square area and similar rental clusters. Removing the debris is step one; then we camera-inspect for the real damage. Call (361) 326-5060 before your next turnover.
Yes, if the cold room is caused by leaky supply ducts or disconnected returns losing conditioned air to attics or wall cavities. We see this in historic village homes where settlement has separated duct joints. We pressure-test the system, locate the leaks, and seal them. If the issue is insufficient duct sizing or a blocked run, we’ll tell you that too. Call (361) 326-5060 for diagnosis.
Storrs’s cold, snowy winters and humid summers mean ducts expand and contract through wide temperature swings, stressing sealant bonds. Moisture from summer humidity condenses on cool metal in unconditioned spaces, promoting rust that undermines new seals. We use mastic rated for temperature cycling and address insulation and condensation control as part of the job, not as separate upsells. Call (361) 326-5060 to discuss your specific system.
Yes, our cleaning and sealing protocols align with NADCA guidelines for source removal, containment, and post-job verification. We perform agitation cleaning with negative-air containment before applying sealant, test airflow balance after sealing, and document with photos. The 365-Day Done Right Promise backs the work in writing. Call (361) 326-5060 to schedule a NADCA-aligned duct sealing job.
