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.

AfterFast, Reliable Air Duct Cleaning Across Guilford
Air duct cleaning in Guilford typically costs between $450 and $900 for a full residential system, depending on home size, duct configuration, and the condition we find once the camera goes in. Homes along the shoreline and older colonials tend to run toward the upper end because those systems have more corrosion, collapsed runs, and decades of accumulated debris. We schedule Guilford jobs Monday through Saturday, with most cleanings completed inside a single day. Call (806) 606-6902 and you’ll get a written price before any work starts, not a vague estimate over the phone.
Guilford isn’t like inland towns when it comes to ductwork. The salt-humid air off Long Island Sound works its way into return plenums and eats galvanized metal from the inside out. We see it every week, from Sachem’s Head down through the tidal marsh corridors. This page explains what’s actually going on inside Guilford’s duct systems, what it costs to fix, and how we document every run we touch. Our air duct cleaning approach starts with a camera, not a vacuum, because you deserve to see the problem before anyone asks you to pay for a solution.
Why CleanRun Air Duct Cleaning Is Guilford’s Preferred Air Duct Cleaning Company
CleanRun has been operating under the H.A.V.E.N. Standard since 2013, and the teams we send into Guilford are background-checked, uniformed, and identified by name before they step through your door. That standard has four clauses, and the one that matters most to Guilford homeowners is Clause 1: a written price before any work starts. You’ll know the full cost of the job before a single panel comes off.
What separates us in Guilford is the Documented Photo Record. Every duct run is photographed before and after, and those images are delivered to you as part of the standard job record. You can look at your phone and see exactly what was pulled out of the return drop in your colonial. You don’t have to take anyone’s word for it. Tomas Reyes, who leads operations for CleanRun, has built the company around that principle since day one: evidence over persuasion.
We also offer a Free Second Opinion on any written estimate. If you have a quote from another company that seems suspiciously low (a $79 whole-house special, for instance), bring it to us. We’ll put our written number next to it and show you what the difference actually buys in terms of equipment, documentation, and follow-through. The 365-Day Done Right Promise backs every job in writing. If it’s not right, we make it right. That applies in Guilford the same as anywhere else we work.
Our Air Duct Cleaning Services in Guilford
Residential Duct Cleaning
Guilford’s housing stock runs the gamut from 1700s center-chimney colonials to 1970s split-levels off Route 77. A residential cleaning here isn’t a one-size-fits-all job. The colonial near the Green with hand-hewn floor joists requires a different approach than a mid-century ranch with original galvanized trunk lines. We map the system before we clean it, so we know what we’re dealing with behind the plaster and timber.
Commercial Duct Cleaning
Guilford’s commercial spaces, from the offices along the Post Road to the shops near the train station, accumulate dust faster than most building owners expect. Coastal humidity makes return-air plenums a collection point for salt-laden particulate that inland commercial systems simply don’t see. We schedule commercial work around business hours and provide the same written-price, photo-documented process we use on every residential job.
Supply Duct Cleaning
Supply ducts deliver conditioned air to your rooms. In an older Guilford home, those supply runs are often original galvanized sheet metal with rust forming at the seam joints. That rust flakes off and blows into bedrooms, settling on furniture and windowsills. Source removal with HEPA-filtered negative-pressure extraction gets that material out without releasing it back into the living space. We photograph the inside of the supply run before and after so you can see the difference.
Return Duct Cleaning
Return ducts pull air back to the air handler, and in Guilford they’re often the dirtiest part of the system. Shoreline homes consistently show mold growth and rust-pitting on return-side metal in systems that are only 20 to 30 years old, a deterioration rate typically associated with much older inland systems. The culprit is consistent salt-humid air drawn through leaky return plenums. Cleaning these runs properly requires more than a vacuum; it requires sealing the plenum connections afterward so the problem doesn’t return in six months.

BeforeAfterTrusted Brands We Service in Guilford
We service and clean duct systems running equipment from Honeywell, Aprilaire, and Abatement Technologies. Our crews use Rotobrush and Nikro equipment for source removal and video inspection, and we stock the filters and components Guilford homeowners most often need for these systems. If your system runs on a specific filter media or Aprilaire housing, we carry compatible parts on the truck so we don’t have to schedule a follow-up visit. The same goes for Guardsman sanitizing products when a job calls for mold remediation inside accessible duct sections. You can verify these brands independently before you agree to a price; that’s the point.
Common Air Duct Cleaning Problems We See in Guilford Homes
- Mold growth in 20-to-30-year-old shoreline systems. Sachem’s Head and the tidal marsh corridors consistently show visible mold and biofilm inside return ducts far earlier than inland homes. The salt-humid marine air gets pulled in through leaky return plenums and condenses on the metal, creating a moisture bed for mold. This isn’t surface dust; it requires source removal and often plenum sealing to correct.
- Rust-pitted galvanized supply runs. The salt air off Long Island Sound corrodes galvanized duct joints from the inside. Homeowners notice rust flakes on register covers or reduced airflow to second-floor bedrooms. The fix is cleaning plus sealing the compromised joints, not just vacuuming out the rust.
- Collapsed return ducts in original crawlspaces. Guilford’s colonials and Capes often route return air through dirt-floor crawlspaces that have held damp soil for two or three centuries. The weight and moisture flatten flexible or thin-metal return runs, starving the air handler and pulling unfiltered air directly into the system.
- Disconnected flex duct in retrofitted knee walls. Many older Guilford homes had forced-air systems retrofitted into spaces never designed for ductwork. Flexible ducts in knee-wall attics detach from registers over time, dumping conditioned air into unheated space and drawing mold spores back into the living areas through negative pressure.
Pricing for Air Duct Cleaning in Guilford, CT
Here are the numbers we put on paper in Guilford, updated for the current market. A full residential system cleaning on a 1,500-square-foot ranch runs $450 to $600. A 2,500-to-3,000-square-foot colonial, especially one with hard-to-access runs through original timber framing, runs $650 to $900. Commercial spaces in Guilford run $800 to $1,800 depending on square footage and duct complexity. Video inspection is included with every full system cleaning. If we find collapsed return runs or disconnected flex duct, the replacement and sealing work is quoted separately in writing before anything is touched. That’s Haven Standard Clause 1. There is no per-vent price, no bait coupon, and no surprise line item at the end.

FAQs - Air Duct Cleaning in Guilford
Guilford’s shoreline homes pull salt-humid air into the return side through leaky plenum connections, and that air condenses on cooler metal duct surfaces, creating the moisture bed mold needs to colonize. We regularly find visible mold growth inside systems that are only 20 to 30 years old in Sachem’s Head and the marsh corridors, a timeline that would be unusual in inland New Haven County. The fix starts with cleaning and camera inspection, then sealing those leaky connections so the moisture source is cut off. Call (806) 606-6902 if you want a camera in your ducts before deciding anything.
We don’t open plaster walls. We map the system with a video inspection camera, then access the runs from the registers, return drops, and plenum points already in place. The negative-pressure extraction equipment creates suction at the air handler while we work each accessible run from the register end. Where we find crushed or disconnected sections, we document them on camera and quote the replacement or sealing work in writing before touching anything. That’s Haven Standard Clause 1.
Return ducts bring air back to the air handler, and in Guilford they’re exposed to the raw crawlspace and marine air, so they collect mold, rodent nesting, and damp debris that supply ducts never see. Supply ducts distribute air the other direction and are more likely to accumulate rust flakes, construction debris, and fine particulate that gets blown into living spaces. A full system cleaning addresses both, but the camera inspection often shows the return side needs more intensive source removal. The photo record you receive will show the difference clearly.
Salt air absolutely corrodes galvanized metal ductwork, and Guilford proves it. We see rust-pitting through the metal at joint seams in shoreline homes that are two or three decades old. That corrosion weakens the metal, creates gaps at seams, and releases rust particles into the airflow. If the photo record shows perforation through the duct wall, replacement of that section is more cost-effective than cleaning. We’ll show you the image and the written price for either option.
Most original galvanized runs from the 1950s are worth cleaning if they’re intact, and the camera inspection will tell us that within the first twenty minutes. The inland ranch subdivisions off Route 77 and Route 146 tend to have straight trunk lines that clean well and only need joint sealing. If the inspection shows rust through the metal or disconnected sections, we’ll give you a written replacement quote for those specific runs, not a whole-system upsell. The decision should be based on photos, not sales pressure. Call (806) 606-6902 to schedule a Guilford inspection with a written price before any work begins.
