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 Lexington
HVAC cleaning in Lexington means getting the blower, coils, and air handler actually clean, not just vacuuming a few vent covers. Most homes in Lexington pay between $450 and $850 for a full system cleaning that includes the evaporator coil, blower motor, and air handler. We coordinate scheduling and dispatch from our Boston office, but the crews working in Lexington live here and know the town’s housing stock, from colonial-era frames near the Battle Green to 1960s ranches off Woburn Street. Call (737) 727-2314 and a live person answers, 24/7, no phone tree.
Why Cardinal Air Duct Cleaning Is Lexington’s Preferred HVAC Cleaning Company
Lexington homeowners tend to ask the same three questions before booking: what does it cost, who’s actually coming, and how do I know the work was done. We answer all three before we ever step inside. Omar Haddad leads our team, and every technician who shows up in Lexington is background-checked, uniformed, and running pro-grade equipment, not a truck-mounted shop vac. You’ll know the tech’s name before they open the door, and you’ll get a written price before any duct is touched.
Our HVAC Cleaning process is built around proof. After the job, we hand you before-and-after photos of your own system, your own ducts, your own coils. Not stock images. Not a checklist with checkmarks. Actual photos you can zoom in on. That’s why homeowners across Lexington keep calling us back for follow-up work and referrals.
We hold ourselves to the 365-Day Done Right Promise. If the work isn’t right within a full year, we return and correct it at no charge. No fine print on which jobs qualify. Every job qualifies. That’s the longest-standing satisfaction window in the trade, and it applies every time we work in Lexington.
AC Cleaning in Lexington
AC Cleaning in Lexington typically costs $180 to $320 for a standard residential system, and it’s the service most homeowners should schedule before the first heat wave of June. We remove the access panels, clean the condensate pan, check the drain line, and clear the coil fins so your system isn’t working against a layer of dust when humidity spikes. Lexington’s summer weather swings from dry heat to thick, damp air within a week, and a clogged drain line or dirty coil turns that into a frozen evaporator or an overflowing pan.
Coil Access and Debris Removal
The evaporator coil sits inside your air handler, and in Lexington homes it’s often buried in a closet, attic, or crawlspace that hasn’t been opened since the last HVAC service call. We pull the panels, document what we find, and clean the coil with professional coil cleaner, not a spray bottle of household degreaser. Debris that clings to the coil fins reduces heat transfer, which means longer run times and higher bills, and in Lexington where many homes run central AC from June through September, the cost adds up fast.
Drain Line and Pan Service
Lexington’s humid late-summer weeks push more condensate through the drain line than the system handles in May or October. If the line is partially blocked with algae or dust, the pan overflows and you’re looking at water damage near the air handler. As part of AC cleaning, we flush the drain line and clear the trap. In older Lexington homes where the air handler sits in a finished basement, this is the difference between a $250 cleaning and a $2,500 ceiling repair.
Evaporator Coil Cleaning in Lexington
Evaporator Coil Cleaning in Lexington runs $150 to $300 on its own, and it’s the single highest-impact service for an older AC system that’s still cooling but running longer than it used to. The coil is what actually absorbs heat from your indoor air, and when it’s coated in a layer of dust, pet hair, and cooking residue, the system loses capacity. In Lexington homes with original ductwork that’s never been sealed, the coil gets dirty faster because return air pulls from unconditioned spaces.
Access Issues in Lexington Homes
Plenty of Lexington homes have air handlers in tight attic spaces or shallow closets where the coil isn’t easy to see, let alone clean. We bring the right tools for the space, coil brushes, fin combs, foaming cleaners, and a Nikro HEPA vacuum to capture what we loosen. In a 1950s ranch off Woburn Street, we found a coil that hadn’t been cleaned in over a decade, caked with drywall dust from a renovation the homeowners didn’t even know had contaminated the system. The photos we took before and after made the case better than any explanation could.
Hygiene and Airflow Benefits
A clean evaporator coil moves more air and removes more humidity. That matters in Lexington, where July and August bring the kind of muggy air that makes a struggling AC system feel like it’s barely running. If you’ve noticed musty smells when the system kicks on, or the house never quite reaches the thermostat setpoint, the coil is usually part of the story. We clean it, document it, and hand you photos that show exactly what came off.
Trusted Brands We Service in Lexington
The equipment in Lexington homes runs the full range, from 1990s builder-grade units to newer high-efficiency systems from every major manufacturer. We service all of them, and we stock common replacement filters, drain line components, and coil cleaning supplies so Lexington customers aren’t waiting on a part to ship. We also install and recommend Aprilaire and Guardsman filtration products when a Lexington homeowner wants better indoor air quality, and we run Abatement Technologies containment equipment on jobs where the ductwork is heavily contaminated. Our main cleaning tools are Rotobrush rotary brush systems and Nikro HEPA-rated negative-pressure vacuums. That means the debris we dislodge goes straight into the vacuum, not back into your living room.
Common HVAC Cleaning Problems We See in Lexington Homes
- Drywall dust from home renovations. Lexington’s housing stock includes a lot of homes that have been renovated at least once, often while the HVAC system was running. That dust gets pulled into returns and coats the coil and blower. Older homes near Massachusetts Avenue see this constantly.
- Rodent debris in original sheet-metal ducts. Pre-war and mid-century homes in Lexington often have original ducts with gaps and unsealed joints. Mice and squirrels find their way in, and the debris ends up in the blower compartment. We see this most often in homes near conservation land and wooded lots.
- Disconnected flex-duct runs from 1990s retrofits. Homes in Lexington that got flex-duct retrofits decades ago often have separate sections that have pulled loose, dumping conditioned air into attics and crawlspaces. A camera inspection finds these fast.
- Oversized systems short-cycling and building up moisture. Some Lexington homes have AC units sized for a bigger house or a hotter climate. Short cycles don’t remove humidity well, and the constant moisture makes coils and blowers get dirty faster. We clean the system and flag the sizing issue so you can plan ahead.

FAQs About HVAC Cleaning in Lexington
One flat price per system, always. We do not price by the vent. In Lexington’s mix of pre-war colonials, mid-century ranches, and newer construction, counting vents over the phone tells you nothing about what’s actually inside the ducts. We quote after a camera inspection so the price matches the real scope. Call (737) 727-2314 and we’ll walk you through it.
Most Lexington homes need duct cleaning every 4 to 7 years, but not all. Homes with pets, recent renovations, smokers, or a history of moisture or pest issues need it more often. Newer Lexington homes with properly sealed ducts and clean MERV filters often just need filter changes and a coil check. We’ll tell you honestly if cleaning isn’t needed. If your ducts haven’t been looked at in years, a camera inspection answers the question in about 30 minutes.
Yes, and we do it often. Original sheet-metal ducts in Lexington homes from the 1700s through the 1960s often have no accessible cleanouts, so we create access points where needed and seal them properly afterward. Our Rotobrush agitation tools and Nikro HEPA vacuum work in metal and flex duct alike. We document everything with photos, so you can see exactly what came out of the original runs. Call (737) 727-2314 for a quote on your specific home.
We remove the access panels, document the condition, clean the blower wheel with agitation tools, vacuum the blower compartment with a Nikro HEPA unit under negative pressure, and clean the evaporator coil if it’s accessible. The goal is to remove dust, pet hair, and debris before it gets pulled through the system and recirculated through your house. You get photos of the blower wheel before and after, so there’s no guessing whether the work was actually done.
No, and we won’t pretend to. Duct and HVAC cleaning in Lexington is a scheduled job that takes a few hours, and doing it right means bringing the right equipment and taking the time to document the work. We’ll give you a firm, trackable arrival window through our Relay Standard booking experience, and a live person answers the phone when you call. But we don’t do rushed same-day jobs in Lexington. We schedule properly and show up on time.
