Murphy Air Duct Cleaning Inc delivers Cambridge’s most trusted air duct cleaning with IICRC-certified crews, transparent pricing, and same-day service for homes in Harvard Square, Kendall Square, and beyond. We don’t just clean ducts—we solve Cambridge’s unique indoor air challenges year-round.
1. We’re Cambridge-based, not a fly-by-night outfit from out of state
Most duct cleaners in Cambridge are franchises or out-of-town crews passing through. Murphy Air Duct Cleaning Inc is locally owned and operated since 2010, with crews who live and work in Cambridge, Arlington, and Somerville. We know Cambridge’s housing stock—from triple-deckers on Magazine Street to modern condos in Kendall Square—and how duct systems age in this climate. When you call us, you’re talking to neighbors who understand Cambridge’s humidity swings, construction dust, and seasonal HVAC demands. We’re licensed (#CS-12345) and insured, so you’re covered from Porter Square to Inman Square.
2. IICRC-certified crews who treat your ducts like a medical procedure, not a vacuum job
A chimney inspection is a visual check of flue liners and masonry for cracks or obstructions. Similarly, a proper air duct cleaning follows the IICRC’s S520 standard for HVAC system cleaning. Many Cambridge cleaners skip agitation, HEPA vacuuming, or coil cleaning, leaving behind dust that feeds mold and allergens. Our crews use roto-brushes, negative-air machines, and EPA-registered sanitizers to remove 98%+ of debris. We document each step so you get a report—not just a receipt. Learn more about our process.
3. Cambridge’s humidity and construction dust demand more than a once-over
Cambridge’s summers spike humidity, and winters bring salt and road grime tracked into homes near Alewife Brook Parkway or Fresh Pond. Add post-renovation dust from projects in Porter or Central Squares, and your ducts act like a sponge. Most cleaners treat ducts as a one-time chore, but Cambridge homes need proactive care. We recommend a cleaning every 3–5 years for owner-occupied homes, or annually if you have pets, smokers, or allergies. See our August checklist for Cambridge-specific prep.
4. We don’t upsell you on services you don’t need—unlike national chains
Old ducts in Cambridge triple-deckers aren’t automatically hazardous. We inspect first—using cameras and pressure tests—then recommend cleaning, sealing, or replacement only when necessary. Many homeowners waste $2,000–$5,000 on unnecessary replacements after a $400 cleaning quote. Our free estimates include a no-pressure walkthrough. Get your free estimate and compare our transparent pricing to the fine print from out-of-town crews.
5. Local knowledge beats generic advice—especially near the Charles River
Cambridge’s proximity to the Charles River means higher pollen counts in spring and mold risks near waterfront homes in East Cambridge. We tailor our sanitizing agents to local allergens and humidity cycles. For example, we use botanical-based sanitizers in homes near Magazine Beach Park to avoid chemical residues that aggravate asthma. We also know which Cambridge neighborhoods have older duct materials prone to rust—like those in the Avon Hill or Agassiz neighborhoods—and adjust our approach accordingly.
6. Same-day service for emergencies—because Cambridge summers are brutal
When your AC fails during a 95°F Cambridge heatwave, waiting weeks for a duct cleaning isn’t an option. We offer same-day service for emergency calls in Cambridge, Somerville, and nearby towns. Our crews carry HEPA vacuums and antimicrobial treatments to restore airflow quickly. Call us now if you notice weak airflow, musty odors, or increased allergies—especially in homes near Kendall Square where office buildings and residential units share HVAC systems.
7. A 100% satisfaction guarantee—because Cambridge homeowners deserve peace of mind
We stand behind our work with a 30-day satisfaction guarantee. If you’re not happy with the results, we’ll return within 7 days to re-clean the affected areas at no extra cost. No fine print, no hidden fees. We also offer a 1-year warranty on all sanitizing treatments to protect against mold regrowth—a common issue in Cambridge’s older homes.

Frequently Asked Questions
How do I know if my Cambridge triple-decker’s air ducts really need cleaning?
Start with a visual check: remove vent covers in your kitchen, bathroom, or bedroom and shine a flashlight inside. If you see thick dust, mold spots, or debris, it’s time for a cleaning. Cambridge’s older homes often hide buildup behind grilles near the Charles River or in attics with poor insulation. See our DIY inspection guide for step-by-step help.
What’s the average cost for air duct cleaning in Cambridge, and what affects the price?
In Cambridge, expect $350–$750 for a standard 3-bedroom home, depending on duct length, accessibility, and whether you need sanitizing. Costs rise for homes near Harvard Yard with tight crawl spaces or in East Cambridge where parking restrictions add labor time. Explore the 6 cost factors that Cambridge homeowners often overlook.
Can Murphy Air Duct Cleaning handle my Cambridge condo’s HVAC system safely?
Absolutely. We clean condo HVAC systems in buildings like 100 Memorial Drive or One Kendall Square without disrupting residents. Our crews coordinate with property managers, use low-noise equipment, and follow condo board guidelines. We also offer after-hours service for buildings with strict noise ordinances. Contact us to schedule a condo-friendly cleaning.
Do you clean dryer vents too, or just air ducts? I live near Porter Square and worry about lint fires.
We clean both air ducts and dryer vents in Cambridge homes. Lint buildup in dryer vents is a leading cause of house fires, especially in older homes near Porter Square with long duct runs. Our cleaning removes lint from the vent pipe to the exterior, reducing fire risk and improving dryer efficiency. Learn the 5 essential steps for Cambridge homeowners.
