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.

AfterFast, Reliable Air Duct Cleaning Across Hartford
Air duct cleaning in Hartford typically runs $350 – $650 for a full residential system and is scheduled within a few business days, with most jobs completed in three to five hours. If your home was built before 1950, has an oil furnace, or you’ve never had the ducts opened, you’re likely looking at the upper end of that range due to decades of soot and particulate buildup.
We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our Air Duct Cleaning in Hartford crews work from our local Hartford office. We know the city’s housing stock: the triple-deckers of Barry Square, the Victorians of the South End near Wethersfield Avenue, the pre-war colonials of the North End. We’ve cleaned ducts in homes with original galvanized steel from the 1920s and in commercial systems on Capitol Avenue. When you call (361) 326-5060, a live person answers, 24 hours a day, and we’ll give you a written price before any work starts.
Why Hollis Air Duct Cleaning Is Hartford’s Preferred Air Duct Cleaning Company
Hartford’s older housing stock creates problems most duct cleaners outside the Connecticut River Valley don’t recognize. We’ve been at this since 2004, and our technicians are trained to distinguish oil-furnace soot from mold, spot crushed branch runs behind knee walls, and identify leaky riveted joints on original galvanized ductwork that cleaning alone won’t fix.
Every job follows The Garrison Standard: arrive inside the quoted window, price in writing before touching anything, complete the work by the book, and leave the site clean. Our 365-Day Done Right Promise covers every repair in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit. No negotiation, no runaround.
Our technicians are background-checked and uniformed. You know who’s walking into your home before they arrive. And our phones are answered by a live person around the clock, not a voicemail loop that dumps you into a callback queue until Monday.
Commercial Air Duct Cleaning in Hartford
Commercial Air Duct Cleaning in Hartford covers office buildings, retail spaces, multi-unit housing, and institutional properties with larger, more complex systems than typical residential work. We use Nikro negative-air machines and Rotobrush rotary brush systems to remove accumulated debris from supply and return trunks, with HEPA filtration to protect occupied spaces during the job. A commercial system in Hartford typically runs $800 – $2,500 depending on square footage, system complexity, and accessibility. Properties near I-84 or in the downtown corridor often have rooftop units or basement mechanical rooms with limited access, which can extend labor hours.
Multi-Unit and Property Management Work
Triple-deckers and apartment buildings in neighborhoods like Parkville and Frog Hollow frequently have shared returns and multiple branch runs that less experienced crews quote as single-family jobs. We scope every branch with video inspection and price per system, not per vent, so you know the full cost before we start.
Post-Renovation and Turnover Cleaning
Construction dust from Hartford’s ongoing rehab work settles in ductwork and recirculates for months. We clean after renovations, between tenants, or as part of annual maintenance for property managers who need documentation for insurance or regulatory compliance.
Air Duct Cleaning Services in Hartford
Air Duct Cleaning Services in Hartford from Hollis include full system cleaning, video inspection, and duct sealing for residential and light commercial properties. A typical single-family home runs $350 – $650; larger Victorians or homes with oil-furnace soot buildup often fall in the $500 – $850 range. Every job starts with a written price and ends with before-and-after photos of your own ducts, not stock images.
Video Inspection and Problem Diagnosis
We run a camera through your supply and return lines before and after cleaning. In Hartford’s older homes, we regularly find crushed flex behind knee walls, disconnected branch runs in attic spaces, and the black soot from oil furnaces that homeowners mistake for mold. The camera shows you exactly what we’re seeing, and we explain what needs cleaning versus what needs sealing or repair.
Duct Sealing After Cleaning
Original galvanized steel ducts with riveted joints leak conditioned air into basements and attics even when clean. We seal accessible joints with mastic after source removal, which drops static pressure at the air handler and gets heat and AC to the rooms that were starving. Sealing is often the real fix; cleaning alone can actually make airflow worse by removing the debris that was partially blocking the leaks.

Trusted Brands We Service in Hartford
Our equipment roster includes Rotobrush rotary brush systems for agitation inside duct walls, Nikro negative-air machines for source removal under controlled pressure, and filtration products from Honeywell, Aprilaire, and Abatement Technologies. We stock parts and maintain tools locally through our Hartford office, so we’re not waiting on shipments from out of state when a job needs a specific brush head or HEPA filter. That means faster turnaround for Hartford homeowners and less downtime for commercial clients on Capitol Avenue or in the Insurance District.
Common Air Duct Cleaning Problems We See in Hartford Homes
- Oil-furnace soot mistaken for mold. Many Hartford homes still burn heating oil, and decades of soot buildup coats original galvanized ducts with a black, powdery layer that looks identical to mold in a flashlight beam. We test before we declare, and we’ve saved homeowners thousands in unnecessary remediation quotes by identifying what it actually is.
- Leaky riveted joints on pre-1950 ductwork. Original galvanized steel was joined with rivets, not sealed seams. Cleaning removes the partial blockage, which can increase airflow through the leaks and make the system feel weaker, not stronger, until the joints are sealed with mastic.
- Crushed or disconnected branch runs in triple-deckers and Victorians. Long branch lines to second and third floors, often routed through unconditioned spaces, get crushed by prior renovation work or simply sag and disconnect. We find these with video inspection and rebuild or rehang as needed.
- Mold and mildew from Hartford’s humid basements and attics. The Connecticut River Valley’s cold, wet winters and hot, humid summers create condensation inside poorly insulated ductwork. We address the source with proper cleaning and recommend insulation upgrades where the duct itself is sweating.

FAQs About Air Duct Cleaning in Hartford
Probably not. The black, powdery coating we find in Hartford’s oil-heated homes is almost always soot from decades of combustion, not mold. It looks similar in a dim flashlight beam, which is why less experienced crews or anxious homeowners call for mold remediation that isn’t needed. We run a camera inspection and test when indicated, then remove the soot with negative-air extraction and rotary brush agitation. If you’re worried about what you’re seeing, call (361) 326-5060 and we’ll scope it before you spend money on the wrong fix.
We seal accessible joints on Hartford’s original galvanized ductwork whenever we find leakage, because cleaning alone often makes airflow worse. The debris in old riveted joints was partially blocking air from escaping; once it’s gone, the leaks are exposed. We apply duct sealing mastic after source removal, which drops static pressure and delivers conditioned air to the rooms that need it. Sealing is priced in writing before we start, never added as a surprise at the door.
Yes. Hartford’s triple-deckers in neighborhoods like Barry Square and Frog Hollow have complex branch systems and shared returns that require scoping every line with video inspection. We price per system based on what we find, not a flat per-vent rate that leaves whole branches untouched. Our technicians have cleaned and sealed triple-decker ductwork throughout the South End and North End; we know how to access common returns without disrupting other units.
Hartford’s location in the Connecticut River Valley means cold, humid winters and hot, humid summers, both of which create condensation on ductwork in unconditioned basements and attics. That moisture feeds mold and mildew growth inside the system, and it accelerates corrosion on original galvanized steel. We see this most in homes with poor basement ventilation or attic insulation gaps. Cleaning removes existing growth; sealing and insulation recommendations address the moisture source. Call (361) 326-5060 for an inspection if your basement ducts are sweating or you smell mustiness when the system runs.
It can, if pollen is accumulating in your ductwork and recirculating. Hartford’s spring pollen counts run high due to the river valley’s tree cover and trapped air patterns. Pollen enters through intake points, gaps around filter racks, and leaky return ductwork in attics or basements. We clean the accumulated material and seal the entry points we can access. For ongoing filtration, we can recommend Honeywell or Aprilaire media filters sized to your system. Duct cleaning isn’t a cure-all for allergies, but removing the reservoir of pollen and sealing the leaks that let more in is a concrete step. Call (361) 326-5060 to discuss your specific symptoms and system setup.
