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 Weymouth
HVAC cleaning in Weymouth, MA typically runs $425-$680 for a full system on a ranch or Cape, and most jobs take our crew between 2.5 and 4.5 hours. What drives that price here, more than anything else, is what Weymouth’s coastal air does to ductwork that inland towns never see. Salt-laden humidity off the Fore River and Hingham Bay pushes moisture into basements year-round, which means the evaporator coil, blower, and air handler in a 1960s Cape on Charles Street corrode faster than the same equipment in Randolph. HVAC Cleaning done right in Weymouth means cleaning what the salt air leaves behind, not just vacuuming what you can see. Call (806) 606-6902 and we’ll give you a written price before any panel comes off.
Why CleanRun Air Duct Cleaning Is Weymouth’s Preferred HVAC Cleaning Company
We’ve worked enough homes in North Weymouth, Weymouth Landing, and East Weymouth to know the difference between a dirty system and a salt-corrosion problem. Most HVAC cleaners pull a vacuum and call it done. We photograph the inside of every duct run before and after, so you can see exactly what we removed from your air handler and evaporator coil. That photo record is part of every job we do in Weymouth, not an upgrade.
Tomas Reyes, who leads our Weymouth crews, started this company in 2013 on a simple rule: write the price down before the work starts. That rule is Haven Standard Clause 1, and it applies to every single job. No exceptions, no “it turned out to be more than we thought.” The written scope and the written warranty are yours before we touch a register. If you want a second opinion on any HVAC cleaning estimate from another company, bring it to us. We’ll put our written number next to theirs, free. That’s how we’ve done it for over a decade.
Our HVAC Cleaning Services in Weymouth
Evaporator Coil Cleaning
On a Weymouth Cape with the original 1960s duct runs, the evaporator coil is usually where marine aerosols and condensate combine into a bio-film that re-colonizes freshly cleaned ducts within a season. We pull the coil access panel, photograph what’s there, clean it with a professional-grade coil cleaner, and treat the surface to resist re-growth. Skip this step and your duct cleaning is half done. Weymouth’s humidity makes sure of that.
Blower Cleaning
The blower wheel in a 50-year-old furnace in a North Weymouth basement has spent decades pulling salt-damp air across its fins. That leaves a crust that reduces airflow and pushes your system harder than it needs to work. We remove the blower housing, clean the wheel and the motor, and document it. On systems where the blower has never been pulled, this alone changes the sound of the system.
Condenser Cleaning
Your outdoor condenser sits in Weymouth’s coastal air all year. Salt spray off Hingham Bay settles on the coils, then holds moisture long after a similar unit in Braintree would have dried. We wash the coil, straighten bent fins, and check refrigerant pressures. A fouled condenser means your interior work is wasted, so we clean it as part of the system, not as an add-on.
Air Handler Cleaning
The air handler is the junction box where ductwork meets mechanical equipment, and in Weymouth’s split-levels and ranches it’s usually tucked into a damp basement corner near an unsealed foundation wall. We open the handler, clean the interior surfaces, check the drain pan and line for biological growth, and treat the area so it doesn’t turn into a growth chamber between cleanings. This is where the salt-humidity problem in Weymouth homes concentrates, and where our photo record matters most.
Coil Treatment
After cleaning, we apply a coil treatment that slows re-growth on evaporator and condenser surfaces. In Weymouth, where the tidal air re-wets coils within days of cleaning, this step buys real time between service visits. We’ll tell you what product we use, and we’ll photograph the coil before and after application. You’re not guessing what we did. You’re seeing it.

Common HVAC Cleaning Problems We See in Weymouth Homes
- Salt-air sweating on basement trunk lines. In homes within a few blocks of the Back River estuary, uninsulated 1950s-60s galvanized supply trunks attract condensation during Weymouth’s muggy summers. That moisture feeds microbial matting and accelerates interior rust scale. It also means cleaning alone won’t fix the problem if the basement transitions stay unsealed.
- Unsealed basement duct transitions. Weymouth’s post-WWII housing stock was rarely sealed with mastic at the duct joints. Basement-slab air, carrying moisture and debris, gets pulled into the supply side and re-contaminates the system within one heating season. We seal those transitions as part of our standard cleaning.
- Clogged evaporator coils on coastal homes. Marine salts combine with normal condensate to form a paste that coats the coil fins. That paste is a food source for biological growth, and it suppresses cooling capacity. In Weymouth, a coil cleaning is often the single highest-value part of the entire HVAC cleaning.
- Rust scale knocked loose but not removed. Rotary brushing without negative pressure dislodges rust flakes throughout the duct runs, then leaves them sitting at the next elbow. In Weymouth’s galvanized systems, that scale is large and sharp. We run negative pressure continuously during agitation, so what gets knocked loose gets pulled out, not rearranged.

FAQs - HVAC Cleaning in Weymouth
In Weymouth, a full HVAC cleaning should be done every 2 to 3 years, not the 3 to 5 years often quoted for inland Massachusetts. Homes within a half-mile of the Fore River, Back River, or Hingham Bay may need coil and blower cleaning annually. If we photograph microbial matting in your air handler, we’ll recommend a treatment and a shorter interval. The photographic record tells us what the schedule should be, not a generic reminder post. Call (806) 606-6902 and we’ll assess your system.
Weymouth is a peninsula, surrounded by tidal water on three sides. Your relative in Randolph is a few miles inland, where air dries out faster and carries far less salt. Your 1950s or 1960s ranch likely has original galvanized sheet-metal ducts in an uninsulated basement that draws in salt-humid air year-round. That combination produces the rust scale and dark microbial matting we see routinely in North Weymouth and the older streets off Commercial Street. For a written assessment of your system, call (806) 606-6902.
Yes, if the odor source is inside the ducts or air handler. In most Weymouth basements, the musty smell traces to condensation on uninsulated trunk lines, biological growth in the air handler drain pan, or debris pulled in through unsealed transitions. We clean the system, photograph every run, seal the transitions with mastic, and treat the coil and pan. Then we show you the photos. If the smell returns, our 365-Day Done Right Promise means we correct it in writing. Call (806) 606-6902 to schedule.
They need different priorities. Homes near the former South Weymouth Naval Air Station are generally newer construction with sealed duct systems, so contamination tends to be more about dust loading and construction debris than rust. North Weymouth, especially within a few blocks of the Back River estuary, is where we find the worst salt-corrosion and microbial matting inside 1950s-60s galvanized trunks. We decide the cleaning approach after camera-inspecting your system, not based on the neighborhood name. Call (806) 606-6902 for a quote specific to your home.
Three things. First, replace your filter every 30-60 days, more often during July and August when Weymouth humidity peaks. Second, check that basement duct transitions are sealed with mastic, not duct tape; if they aren’t, we can do that during your next cleaning. Third, run a dehumidifier in the basement from May through October, keeping humidity below 50%. Salt air can’t grow what it can’t condense onto. For a full plan, call (806) 606-6902 and we’ll assess your system in person.
