Mendoza Air Duct Cleaning Inc. doesn’t just clean ducts—we protect what matters most in your Boston home. Our safety-first approach starts with understanding how clogged air ducts silently escalate fire risks and degrade indoor air quality, especially in older Boston neighborhoods where decades of dust and debris can coat your system. We don’t just remove what you see; we eliminate what you can’t—mold spores, pet dander, and even the fine soot that coats your vents after a century-old building’s heating season. Every inspection includes a thermal scan to detect hotspots before they become hazards, because in a city where space is tight and regulations are strict, proactive fire prevention isn’t optional—it’s essential.

Boston’s older housing stock often violates fire safety codes without homeowners knowing. Our technicians are trained to spot violations like improper duct clearances, combustible debris near heat sources, and missing fire dampers—issues that could void your insurance or trigger fines. We provide detailed reports so you can address problems before they become hazards.
CO leaks from ducts or furnaces are a leading cause of accidental poisoning in Boston. We don’t just clean ducts—we test for backdrafting, inspect heat exchangers, and ensure your furnace’s flue is clear. Our reports include CO readings and recommendations to keep your family safe, especially during winter when windows stay shut.
Many Boston homeowners face denied claims after fires or CO incidents because their duct systems weren’t documented as clean or code-compliant. We provide before-and-after photos, lab reports for microbial tests, and signed compliance certificates that satisfy insurers and local fire marshals.
From Beacon Hill’s historic brownstones to South End’s modern condos, each home’s duct system has unique risks. Our team knows Boston’s building codes inside and out—whether it’s asbestos in older ducts, rodent-proofing in North End basements, or humidity control in Back Bay apartments.
We arrive within 24 hours of your call to inspect your ducts, furnace, and venting system using thermal imaging and CO detectors. You’ll get a real-time report of hazards like lint buildup, mold growth, or code violations—no waiting for estimates or hidden fees.
Based on your home’s risks—whether it’s rodent debris in your Jamaica Plain duplex or pollen buildup in your Fenway apartment—we tailor the cleaning method. Options include HEPA vacuuming, rotary brushing, or antimicrobial treatments for mold.
Our team works systematically from the main trunk lines to every vent, using negative-air machines to contain debris. We sanitize ducts with EPA-approved solutions and install UV-C lights if recommended for your system’s needs.
You’ll receive a digital report with photos, CO readings, and code compliance notes. We schedule a 30-day follow-up to ensure no issues recur, and our team is always available for emergency calls—because safety in Boston homes never takes a day off.
"After my furnace started making a strange noise, I called Mendoza. They found a massive lint buildup near the heat exchanger—something my regular HVAC guy missed. The team was here within hours, cleaned everything, and even provided a fire safety report for my insurance. Worth every penny."
"My wife and I both have severe allergies, and our doctor suggested checking the ducts. The difference after cleaning was night and day—no more coughing fits at night. They even found a small rodent nest in the return vent that we didn’t know about. Highly recommend."
"I was skeptical about duct cleaning until I saw the before-and-after photos. The mold in my 1920s Brookline home’s ducts was shocking. Mendoza’s team was thorough, professional, and explained everything in detail. My air smells fresh for the first time in years."
"We had a scare when our CO detector went off randomly. Mendoza traced it to a cracked heat exchanger and clogged flue—issues that could’ve been deadly. They fixed the problem same-day and gave us peace of mind. Can’t thank them enough."
"Living near the airport means dust is a constant battle. After Mendoza cleaned my ducts, the dust in my apartment dropped by 80%. They were on time, respectful of my space, and even sealed some gaps to prevent future buildup. Truly impressed."
"I’ve had duct cleaning before, but Mendoza was the first to check for fire hazards and code compliance. They pointed out a missing fire damper in my basement that my previous cleaner ignored. This isn’t just cleaning—it’s safety."
