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 HVAC Cleaning Across Guilford
HVAC cleaning in Guilford isn’t the same job it is ten miles inland. Salt air off Long Island Sound moves through return ducts, rusting galvanized seams and feeding mold colonies in homes that are only 25 years old. We see it in Sachem’s Head, along the tidal marsh corridors, and in the colonial-era houses along Whitfield Street that were retrofitted for forced air decades ago. If you’re noticing musty air at the registers, rooms that never seem to reach the thermostat setting, or a film of dust that returns days after cleaning, the problem is usually inside the ductwork and the coil. Call CleanRun Air Duct Cleaning at (806) 606-6902 and we’ll give you a written price before any panel comes off.
Key Takeaways
- Full HVAC cleaning in Guilford typically runs $425-$780 depending on system size and condition.
- Shoreline homes here show rust and mold in ductwork far earlier than inland houses.
- Every job includes a Documented Photo Record of inside each duct run, before and after.
- Written price before work starts, always, under Haven Standard Clause 1.
Why CleanRun Air Duct Cleaning Is Guilford’s Preferred HVAC Cleaning Company
We’ve been cleaning and repairing HVAC systems since 2013, and the homes we work in around Guilford have taught us things you can’t learn from a training manual. The colonial on Broad Street with ducts routed through a hand-hewn framing bay. The 1990s Cape near the East River where the return plenum was pulling salt-humid air through three separate gaps. The ranch off route 77 whose original 1950s galvanized runs had been quietly rusting from the inside. Our crews know what these systems look like when they’re opened, and we photograph every inch before we touch anything.
Tomas Reyes founded CleanRun on a simple premise: show the customer what’s actually in their ducts, put a number on the fix before work begins, and stand behind the result in writing. That’s the 365-Day Done Right Promise. No fine print. No bait price that balloons once the van is in the driveway. Just a documented record of what was found, what was done, and what it cost.
Every technician who works in Guilford is background-checked, uniformed, and identified by name before arrival. We answer the phone with a live person around the clock. And we carry one flat written price per system, not per vent, not per surprise.
Our HVAC Cleaning Services in Guilford
Evaporator Coil Cleaning
In Guilford’s humidity, evaporator coils collect a dense mat of dust, salt residue, and biological growth that standard filter changes never address. A fouled coil raises head pressure, shortens compressor life, and is the most common reason an AC freezes up in August. We access the coil, photograph the buildup, then clean it with professional-grade coil cleaners that break down salt deposits and biofilm without etching the aluminum fins. A typical evaporator coil cleaning in Guilford runs $180-$320.
Blower Cleaning
The blower wheel is the lungs of your system, and in Guilford homes especially, it accumulates a fine layer of salt dust and particulate that throws the wheel out of balance. That off-balance spin wears motor bearings and reduces airflow to distant registers, which is why second-floor bedrooms in older colonials never seem to cool properly. We remove the blower assembly, clean each blade, and photograph the result. Expect $140-$240 for a standalone blower cleaning in Guilford.
Condenser Cleaning
Outdoor condensers along the shoreline take a beating. Salt spray and coastal fog coat the fins, and that coating traps dirt and grass clippings that restrict heat rejection. We see condensers in Sachem’s Head and along the marsh corridors that look ten years older than their actual age. We clean the coil with low-pressure water and a fin-safe degreaser, then straighten any bent fins that are choking airflow. Condenser cleaning in Guilford is usually $130-$210.
Air Handler Cleaning
The air handler is where the blower, coil, and drain pan live together, and it’s the component most affected by Guilford’s crawlspace humidity. Standing water in the drain pan breeds mold, and that mold gets distributed through every run. We clean the cabinet interior, flush the drain line, treat the pan with an antimicrobial, and document everything. A full air handler cleaning ranges $200-$360 depending on access and condition.
Coil Treatment matters more in Guilford than in most towns, because the salt loading doesn’t just sit on the surface; it works into the fin contact points. We apply a protective coil treatment after cleaning on shoreline systems to slow corrosion between cleanings. It’s an extra $60-$85 per coil and does more long-term good here than almost anywhere else in New Haven County.
HVAC Cleaning at CleanRun is never a one-size-fits-all job. Every system we open in Guilford gets its own scope, its own price, and its own photo record.

Common HVAC Cleaning Problems We See in Guilford Homes
- Salt-rusted galvanized ductwork in 25-year-old homes. Shoreline properties pull marine humidity through leaky return plenums, and the first ten feet of supply duct often shows pitting and rust bloom that inland techs would call a 50-year-old system. Cleaning reveals it; sealing stops it.
- Disconnected or crushed runs in retrofitted colonials. Homes built in the 1700s and 1800s along Whitfield Street and around the Green were never designed for forced air. Ducts were routed through framing bays and knee walls, and decades of seasonal movement have pulled joints apart or flattened flex runs. Supply air never reaches the second floor.
- Mold inside duct insulation after nor’easter-driven moisture. When coastal storms force water into poorly sealed duct connections, fiberglass liner inside ducts becomes a damp substrate. Standard vacuum cleaning doesn’t touch it. Source removal does, and that’s what we perform.
- Coil freeze-ups in August from restricted airflow. Guilford’s summer humidity means coils sweat more, and when a fouled coil or dirty blower restricts airflow, the coil ices and the system shuts down. We see this every summer, usually in homes where the coil hasn’t been cleaned in five or more years.
Pricing for HVAC Cleaning in Guilford, CT
A full system clean in Guilford, covering the evaporator coil, blower, air handler, and accessible duct runs, typically falls between $425 and $780 depending on the size of the house, the number of returns, and how much the shoreline environment has punished the metal. Standalone jobs are less: evaporator coil cleaning runs $180-$320, blower cleaning $140-$240, condenser cleaning $130-$210. If we find rusted or disconnected runs during the clean, we’ll quote the sealing or replacement separately, in writing, before any additional work happens. What you won’t see is a $79 teaser price that triples once we’re on site. We don’t do per-vent pricing. We don’t do surprise add-ons. We name the price, you approve it, we do the work, and we hand you a photo record of the inside of every run.
The real wildcard in Guilford is what the camera finds. A house on the marsh side of town with a leaky return may need coil treatment and source removal that a Clinton house doesn’t. That’s scope, not markup. We’ll show you the photos and let you decide.

FAQs - HVAC Cleaning in Guilford
Because salt-laden marine humidity from Long Island Sound is pulled through leaky return plenums and into galvanized duct runs, where it condenses and sits against the metal. We’ve opened systems in Sachem’s Head and along the marsh corridors where the first ten feet of supply duct showed visible rust pitting and bloom on a mid-1990s colonial. The owners had no idea. We ran a camera down the run, mapped the compromised sections, cleaned the system with HEPA-filtered negative pressure, then sealed every joint and replaced the pitted runs with corrosion-resistant material. The cleaning removes the accumulated salt and debris; the sealing and replacement stop it from coming back. Call (806) 606-6902 for a written assessment.
We access what the framing allows, and we photograph what we can’t. The ducts in Guilford’s 18th- and 19th-century homes were often routed through hand-hewn bays, knee walls, and crawlspaces that were never built for service access. That means some runs can only be cleaned from the register end or through small access cuts we open and reseal. We use camera inspections to see what’s inside before we commit to a cleaning method, and we’ll tell you plainly if a run is unreachable without opening a wall. Most of the time we can clean and seal it from the accessible side. The photo record will show you exactly what we reached and what we found.
Source removal means physically extracting the accumulated debris, salt dust, and biological growth from inside the ductwork using HEPA-filtered negative-pressure equipment, rather than agitating it and hoping it ends up in the vacuum. For Guilford shoreline homes, this matters because the buildup isn’t just dust. It’s salt-laden particulate that has been deposited in layers and often bound to moisture-driven mold inside the duct. Rotobrush and Nikro extraction tools pull that material out from the duct walls themselves. A standard shop-vac pass doesn’t. We include before-and-after photos of every run so you can see the difference instead of taking our word for it.
If it freezes up in August, it’s not working fine. The freeze-up is the symptom. The cause is usually restricted airflow across the evaporator coil, and in Guilford the culprit is typically a coil fouled with salt-laden dust and biological film that limits heat transfer. When airflow drops, the coil temperature drops below freezing, condensation turns to ice, and the system shuts down. Cleaning the coil removes that restriction. We also check the blower wheel, because a dirty blower can produce the same freeze-up. A coil cleaning in Guilford runs $180-$320. The camera will show you what’s actually on the fins before we clean them.
The blower is one component; the air handler is the cabinet that contains the blower plus the evaporator coil, drain pan, and often a section of the return plenum. In Guilford homes with crawlspace-mounted air handlers, the cabinet sits in the dampest, saltiest air in the house, and that environment affects the whole assembly, not just the fan blades. Cleaning the blower alone removes debris from the wheel but leaves the coil, pan, and cabinet interior untouched. A full air handler cleaning addresses all of it. We’ll quote whichever scope matches what we find, in writing, before work starts.
If your system is pushing years of shoreline air through your house, the fix starts with a look inside. Call CleanRun Air Duct Cleaning at (806) 606-6902 and we’ll give you a written price, a documented photo record, and a clean system that doesn’t quietly rust from the inside.
