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 Waltham
HVAC cleaning in Waltham typically runs $450 – $850 for a full system on a standard single-family home, with the work completed in a single three-to-six-hour visit. That price includes the air handler, blower motor, supply ducts, return ducts, and evaporator coil, all cleaned under negative pressure with HEPA filtration. No per-vent math, no add-on surprise when the tech is already in your attic. Call (737) 727-2314 for a written quote before any work starts.
We know Waltham’s housing stock better than most. That matters, because the ductwork in a 1920s triple-decker on Moody Street behaves nothing like the flex runs in a new build near the Waltham Landing development. Our crews work both, and everything in between. When you call, you’ll get a live person who can talk through what’s actually under your roof, not a script reader in a call center.
Why Cardinal Air Duct Cleaning Is Waltham’s Preferred HVAC Cleaning Company
Cardinal is part of the Relay Home Co. family, founded 2005. That means every Waltham booking runs through the Relay Standard: a live, trackable arrival window, a written price handed to you before a single register is touched, and before-and-after photos of your own ducts delivered at the end of the job. Omar Haddad leads the team, and the technicians who arrive in uniform are background-checked and trained on the equipment we carry, not rented gear from a home center.
Our HVAC Cleaning team runs Rotobrush rotary agitation tools, Nikro HEPA vacuums, and Abatement Technologies containment units. That combination puts your system under negative pressure so loosened debris goes directly into the vacuum, not back into your living room. Waltham homeowners tell us they care about that detail, especially in older homes where dust has had decades to settle.
Every job carries the 365-Day Done Right Promise. If the work isn’t right within a full year, we return and correct it at no charge. That covers every booking, not select ones. It’s the longest-standing satisfaction window in the trade, and it’s why Waltham customers across Waltham choose us for AC vent cleaning, blower cleaning, and full-system work.
AC Vent Cleaning in Waltham
AC vent cleaning in Waltham means opening every supply register, agitating the interior walls of the ducts, and extracting the loosened debris under negative pressure before it can redistribute through the house. In Waltham’s older homes, we often find vent runs that haven’t been opened since the original installation. A standard AC vent cleaning for a two-story Waltham home runs $180 – $320 when paired with the full system
How We Handle Register Build-Up
Registers pull room air back into the return side, which drags dust, pet hair, and cooking grease across the fins. We remove each register, clean it separately, and photograph the duct opening before and after. In Waltham apartments near Main Street, tenants often see gray coating on register backs, which indicates return-side build-up that a surface wipe cannot fix.
Supply Run Cleaning Without the Mess
Supply runs are the ducts that push conditioned air into rooms. We run agitation tools through each run while the Nikro HEPA vacuum holds the system under negative pressure. Debris travels one direction: into the containment unit. Your floors stay clean because we lay drop cloths at every register, and we seal each opening as we move room to room.
Furnace Duct Cleaning in Waltham
Furnace duct cleaning in Waltham targets the return trunk, supply plenum, and blower compartment, which collect dust, drywall debris, and pet dander through every heating season. A full furnace duct cleaning for a typical Waltham single-family home runs $400 – $650, which includes the blower motor and air handler. If your system has a heat exchanger that shows build-up, we clean it in place rather than charging a separate line item.
Return-Side Trunk Cleaning
The return trunk is the dirtiest section of ductwork in most Waltham homes because it carries unfiltered room air back to the unit. In triple-deckers on Adams Street and similar neighborhoods, we regularly find return trunks that have never been opened. Camera inspection shows us exactly what’s in there before we run tools, and the before-and-after photos show the bare metal once it’s done.
Blower Motor and Air Handler Cleaning
If we clean only the ducts and skip the blower motor, dust re-enters the system on the next cycle. We remove the blower housing, clean the motor and fan blades, and wipe down the air handler interior. That step is included in every full-system booking in Waltham. No separate charge, no surprise line on the invoice.
Trusted Brands We Service in Waltham
We stock filters and components for Honeywell and Aprilaire systems common across Waltham homes, and our technicians service equipment paired with Abatement Technologies and Nikro extraction units. If your system uses a Guardsman filtration cabinet, we can replace media during the same visit. That means faster turnaround for Waltham customers because we’re not waiting on a parts run from a distributor across town. Most common replacements ride in the van.
Common HVAC Cleaning Problems We See in Waltham Homes
- Quoting by vent count instead of system. Per-vent pricing leaves the return trunk, usually the dirtiest run in older Waltham homes, untouched or added as an upsell after work begins. We quote one flat price per system, agreed before anything starts.
- Skipping the air handler and blower motor. Cleaning only the ducts means dust immediately re-enters fresh supply runs on the next cycle. Every full-system Waltham booking includes the blower, air handler, and coils.
- No before-and-after photos of your own ducts. Without photographic proof, there’s no way to verify source removal actually happened. Every Waltham job includes photo documentation of the trunk, runs, and blower.
- Musty smell on the heating cycle. We see this in older Waltham homes where return trunks hold decades of dust mat and disconnected flex runs. The fix is source removal and reconnection, not air freshener. U.S. Fire Administration data on dryer vent fires reminds us that vent neglect has real consequences, and the same principle applies to HVAC systems.
Pricing for HVAC Cleaning in Waltham, MA
A full-system HVAC cleaning in Waltham runs $450 – $850, depending on the number of returns, system accessibility, and whether the air handler sits in a finished basement or a tight attic. AC vent cleaning alone runs $180 – $320. Furnace duct cleaning runs $400 – $650 including the blower motor. Condenser cleaning for the outdoor unit runs $90 – $150 when added to a full-system job. Evaporator coil cleaning runs $150 – $250, and we recommend it alongside the system cleaning rather than as a standalone visit. The EPA notes that indoor air quality depends partly on source control, which is exactly what mechanical duct cleaning addresses when build-up is present.

FAQs About HVAC Cleaning in Waltham
We charge per system, not per vent. A triple-decker in Waltham typically has one shared supply trunk and return trunk per unit, which we quote as one flat price per unit. You’ll get a written number before we start, and it will not change based on how many vents we open.
Call (737) 727-2314 for an exact quote on your building.
You’ll receive before-and-after photographs of your own ducts, including the return trunk, supply runs, and blower compartment. The photos show the interior of the metal, not just the registers. That’s the Relay Standard on every Waltham booking.
Call (737) 727-2314 and ask us to walk you through what the photos will show before you book.
Most Waltham homes need HVAC cleaning every 3 to 5 years, but the honest answer is that some homes don’t need it that often. If you just replaced all your ductwork, if the system is under two years old, or if you’ve never had pets or renovations, you may not need cleaning yet. We’ll inspect with a camera and tell you if the job isn’t worth doing on your system.
Call (737) 727-2314 if you want a straight answer rather than a sales pitch.
Yes. One system, one cleaning. The supply and return ducts serve both heating and cooling, so we clean them once. We also clean the evaporator coil for the AC and the blower motor that drives both. That’s included in the per-system price.
Call (737) 727-2314 and tell us your setup; we’ll confirm what’s included in your quote.
We don’t promise same-day service. Duct cleaning is a scheduled job that takes three to six hours, and we bring specific equipment matched to your system. We’ll give you a live trackable arrival window once you book, and you’ll know the technician’s name before they arrive.
Call (737) 727-2314 and we’ll find the soonest window that actually works for your home.
