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 Waltham
A standard air duct cleaning for a typical Waltham home runs $450 – $750, takes about 3 to 5 hours, and includes a written price before any work starts. We schedule work across every Waltham neighborhood, from the triple-deckers off Moody Street to the ranches near Trapelo Road. If you’ve been wondering what’s actually moving through the air in your house, call (737) 727-2314 and we’ll walk you through what a real cleaning involves, what it costs, and whether your system even needs it yet.
Why Cardinal Air Duct Cleaning Is Waltham’s Preferred Air Duct Cleaning Company
Waltham presents a specific set of duct problems you won’t find in a brand-new subdivision. Homes here run the full range: 1890s triple-deckers with steam heat converted to forced air, 1950s capes with original ductwork, and a surprising number of 1920s colonials where the return runs were never designed for modern airflow. Our Air Duct Cleaning team sees these systems every week, and we quote accordingly. One flat price per system, written down before we touch a single register.
Omar Haddad leads our Waltham work, and the standard he set is simple: if the job isn’t done right within 365 days, we come back and correct it at no charge. That’s the 365-Day Done Right Promise, and it covers every booking, not select ones. You’ll also know the technician’s name before they arrive, see a live trackable arrival window, and receive before-and-after photos of your own ducts when we finish.
We’re part of the Relay Home Co. family, founded 2005, and every Waltham booking is held to The Relay Visibility Guarantee: a live arrival time you can track, photo proof of the work, and a digital invoice you can pay from your phone. No phone tag, no vague windows, no price that shifts at the door.
Air Duct Inspection in Waltham
An Air Duct Inspection in Waltham is a camera walkthrough of your supply and return runs, looking for the specific problems our housing stock tends to hide: old renovation debris, undersized returns, and disconnected joints hidden behind finished basement ceilings. This is where we start when a homeowner says their system is noisy, dusty, or just not moving air the way it used to. A video inspection in Waltham runs $125 – $250 depending on system size and access, and if you book a full cleaning afterward, we credit the inspection fee toward the job.
What the Camera Shows Us
We run a video scope through the accessible runs and record what we find. In Waltham’s older homes, that often means drywall dust from a 1990s renovation, a dead mouse in the return, or a section of flex duct that collapsed behind a wall. You get the footage along with a written recommendation.
When an Inspection Makes Sense
If your house predates 1960 and you’ve never seen the inside of your ducts, you should know what’s in there before you spend money on anything else. For newer builds, an inspection is usually overkill; we’ll tell you that plainly.
Residential Air Duct Cleaning in Waltham
Residential Air Duct Cleaning in Waltham means source removal, not surface dusting. The job involves setting up HEPA-filtered negative pressure at the air handler, then agitating the supply and return runs with a Rotobrush rotary brush system so loosened debris goes straight into the vacuum, not back into your living room. A typical Waltham single-family home runs $450 – $750; a triple-decker unit or larger home with multiple zones runs $600 – $900. Every quote is one flat price per system, agreed before work begins.
The Process in a Pre-1900 House
Older Waltham systems weren’t designed for easy cleaning. Returns may be undersized, shoehorned through finished basements, or rerouted around an addition from decades ago. That’s exactly why we use negative pressure and real agitation, not a nozzle waved at a register.
What We Leave Behind
When we’re finished, you get before-and-after photos of your own ducts, a written invoice, and the 365-Day Done Right Promise. If airflow still feels weak or you find dust settling in the same corners a few months later, call us. We return and correct it at no charge.
Trusted Brands We Service in Waltham
Most of our Waltham customers don’t know what brand their ducts are, and that’s fine. What matters is the equipment we use to clean them: Rotobrush rotary brush systems, Nikro HEPA vacuums, and Abatement Technologies containment units. These aren’t truck-mounted shop-vac shortcuts. They’re professional-grade tools built for source removal, and they’re the same machines we use on commercial jobs. If your system has an Aprilaire filter housing or a Guardsman media cabinet, we’ll inspect that too and tell you if the filter itself is doing its job. Waltham homeowners deserve to know exactly what tools will be in their home before anyone arrives.
Common Air Duct Cleaning Problems We See in Waltham Homes
- Renovation debris in the returns. Waltham has a lot of old houses with finished basements and reworked layouts. Drywall dust and wood shavings from a 15-year-old remodel often sit in the return runs for decades, feeding the blower motor every time the fan kicks on.
- Undersized return ducts on pre-war systems. Triple-deckers and 1920s colonials converted from steam heat frequently have return runs too small for the air handler they’re paired with. Cleaning helps, and so does knowing the limitation so you don’t chase airflow problems that cleaning can’t fix.
- Lint buildup from combined laundry setups. Many Waltham basements route a dryer vent near or into the main return area. Fine lint migrates into the ductwork, where it sticks to damp or oily residue and creates a stubborn coating that needs real agitation to remove.
- Collapsed flex duct in finished basements. We opened a ceiling in the Warrendale neighborhood off Trapelo Road and found a return duct that had been rerouted during a renovation, then partially collapsed. The run was choked with lint and drywall dust. Negative pressure and a camera inspection showed the homeowner exactly what was happening, and after source removal the system moved noticeably more air.
Pricing for Air Duct Cleaning in Waltham, MA
Here’s the honest range for Waltham. A standard single-family home with one system and accessible ductwork runs $450 – $750. Larger homes, multi-zone systems, or houses where the air handler is in a tight finished basement run $600 – $900. Commercial spaces in Waltham’s converted mill buildings are priced per job after a walkthrough. We quote one flat price per system, written down before any work begins, and it does not change at the door. We will never quote you per vent. Waltham’s older housing stock makes per-vent pricing meaningless; a single vent can hide a long, undersized return run that needs real work. Call (737) 727-2314 for a written quote, free of charge.

FAQs About Air Duct Cleaning in Waltham
For most Waltham houses, every 4 to 6 years is genuinely enough. If you renovate, if the home predates 1960 and has never been cleaned, or if someone in the house has severe allergies, you might justify doing it sooner. If a company tells you every Waltham home needs annual duct cleaning, they’re selling you something you don’t need. Call (737) 727-2314 and we’ll give you an honest read on your system.
Because Waltham’s housing stock makes per-vent pricing a bait-and-switch. A $39-per-vent coupon sounds reasonable until you learn that the return run on your pre-1900 triple-decker needs 45 minutes of real agitation and negative pressure, and suddenly the invoice balloons. We quote one flat price per system, agreed before work starts. That’s the whole point: you know the number before our van pulls into your driveway.
We set up HEPA-filtered negative pressure at the air handler, seal the registers, then run Rotobrush agitation tools through the supply and return runs. Loosened debris goes straight into the vacuum, not into your living space. Afterward, we run a camera through the accessible runs so you can see the result. You get before-and-after photos of your own ducts, not a stock image.
We don’t promise same-day service because a proper source-removal cleaning takes 3 to 5 hours and needs to be scheduled, not squeezed between calls. What we do offer is a live trackable arrival window, a technician whose name you know before they arrive, and a written price before any work starts. We’ll schedule you at a time that actually works, and we’ll be there when we say we will.
Sometimes, yes. If your ducts are holding renovation dust, pet dander, or fine lint from a nearby dryer vent, removing that source gets it out of the airflow path. But duct cleaning isn’t a cure for a leaky 1920s envelope or a missing return in a closed bedroom. In Waltham’s older homes, we’ll tell you what cleaning can fix and what it won’t. Call (737) 727-2314 and Omar or one of our techs will give you a straight answer.
