We’ve been driving into Somerville from Lowell for fourteen years, and we know the difference between working in a purpose-built colonial in West Somerville and squeezing equipment into a retrofitted triple-decker off Medford Street. Thomas Hernandez shows up as both owner and lead technician — not a subcontracted crew learning your building on the fly. Our HVAC Cleaning team carries Rotobrush and Nikro systems built for tight-access jobs, which is exactly what Somerville’s dense housing stock demands.
Why Titan Air Duct Cleaning Lowell Is Somerville’s Preferred HVAC Cleaning Company
Our 389 verified reviews averaging 4.7 stars include plenty from Somerville homeowners who found us after a bad experience with a low-bid franchise crew. They mention the same thing: Thomas actually climbs into the crawlspace, reads the duct layout, and explains why the retrofit flex run behind their bulkhead is trapping debris that a standard brush-and-vacuum pass won’t touch.
We’re state-licensed and insured, and we don’t delegate. When you schedule HVAC cleaning for your Somerville property, Thomas is the person who shows up with the equipment, makes the call on whether your evaporator coil needs treatment, and signs off on the job. That matters in a city where buildings from the 1880s have been modified six different ways by six different owners.
Response time to Somerville is typically next-day, sometimes same-day for properties near the Cambridge line or along McGrath Highway where we can park the van without a twenty-minute search. We know which streets have resident-only parking, which alleys accommodate a service vehicle, and which triple-deckers require us to haul a Nikro HEPA vac up a narrow rear staircase because the front bulkhead ceiling is too low.
Our familiarity with Somerville’s ZIP codes — 02143, 02144, 02145 — means we don’t waste your first hour figuring out whether your system is original forced-air or a 2005 retrofit with a condensate pump crammed under the stairs. We’ve seen both. Many times.
Our HVAC Cleaning Services in Somerville
Evaporator Coil Cleaning
In Somerville’s retrofitted triple-deckers, the evaporator coil often sits in a basement air handler shoehorned beneath a 1920s ceiling joist, surrounded by humid, unconditioned air. We pull and clean the coil with foaming cleaner and low-pressure rinse, then inspect the drain pan for algae or sludge — a common failure in systems that run hard from October through April, then sit idle through a humid July. Coil cleaning in Somerville typically runs $180–$320, depending on accessibility and contamination level.
Coil Treatment
After cleaning, we apply an antimicrobial coil treatment using Guardsman products to prevent mold colonization in Somerville’s poorly insulated basement installations. This step gets skipped by crews racing through four jobs a day. It shouldn’t. The combination of six-month heating seasons and humid summers creates exactly the conditions where untreated coils become a source of musty, circulated air. Coil treatment adds $85–$140 to a cleaning service.
Blower Cleaning
The blower wheel in a retrofitted Somerville system works harder than it was designed to, pushing air through kinked flex duct and undersized returns. We remove the blower assembly, clean each vane, balance the wheel, and check the motor amp draw. A dirty blower in these conditions can draw 15–20% more current — you’ll see it on your Eversource bill. Blower cleaning runs $160–$280 in Somerville.
Condenser Cleaning
For Somerville properties with split systems or rooftop condensers — increasingly common in condo conversions near Union Square and Assembly Row — we clean the condenser coils, straighten fins, and check refrigerant levels. Condensers near McGrath Highway or Route 28 collect road particulate faster than units in quieter neighborhoods. Service ranges from $140–$260.
Air Handler Cleaning
The full air handler cabinet — housing, filter rack, drain line, and electrical compartment — gets HEPA-vacuumed and wiped down. In Somerville triple-deckers, the air handler is often the most accessible part of a system with otherwise nightmare ductwork. We treat it as the critical junction it is. Air handler cleaning starts at $200–$350.
Heat Exchanger Cleaning
We inspect and clean heat exchangers in gas-fired furnaces, checking for soot buildup or corrosion that affects efficiency and safety. Given the age of many Somerville heating systems, this inspection can catch problems before they become carbon monoxide risks. Heat exchanger service runs $190–$340.

Trusted Brands We Service in Somerville
We clean and service systems running Honeywell, Aprilaire, and Nikro components — brands we see constantly in Somerville’s mixed-era housing stock. Honeywell media air cleaners and Aprilaire humidifiers are common retrofits in triple-deckers where owners wanted better air quality without replacing the whole furnace. We stock replacement filters and pads for these units, so Somerville customers don’t wait a week for a part. Our Abatement Technologies HEPA filtration runs during every job, protecting your space while we work.
Common HVAC Cleaning Problems We See in Somerville Homes
- Kinked flex duct behind bulkheads. Retrofitted forced-air in Somerville’s triple-deckers often runs through closets and dropped ceilings with 90-degree bends that trap lint and dust. We find these with a borescope before we start, then use flexible-shaft Rotobrush heads to navigate what rigid rods can’t.
- Construction dust from the Green Line Extension. We serviced a triple-decker on Medford Street near the Green Line Extension site. The retrofitted flex duct had a 90-degree kink behind a bulkhead, clogged with fine gray construction particulate and dust. We used a Rotobrush system to clear the run and applied an antimicrobial coil treatment to prevent mold in the humid basement air handler. Properties along Washington Street and Medford Street in East Somerville still show this contamination.
- Mold in uninsulated basement ducts. Somerville’s long heating season keeps furnaces cycling, but humid summers create condensation inside poorly sealed retrofitted runs. Without coil treatment and proper drainage, we find mold in the air handler and the first few feet of supply trunk — exactly the air you’re breathing when the system kicks on in October.
- Access problems for alley-load properties. Many Somerville triple-deckers have rear entrances through narrow alleys with parking restrictions. We’ve developed a compact equipment setup for these jobs — smaller HEPA vac, collapsible ladders, brush systems that break down for stair carries. A crew with only truck-mounted gear simply can’t complete the work.
Pricing for HVAC Cleaning in Somerville, MA
Full HVAC cleaning in Somerville runs $280–$580 for a typical residential system, with most triple-decker retrofits landing in the $350–$480 range due to access complexity. Here’s how individual services break down:
- Evaporator Coil Cleaning: $180–$320
- Coil Treatment (antimicrobial): $85–$140
- Blower Cleaning: $160–$280
- Condenser Cleaning: $140–$260
- Air Handler Cleaning: $200–$350
- Heat Exchanger Cleaning: $190–$340
What moves the price: accessibility (crawlspace vs. full basement), contamination level (construction dust takes longer than household dust), and whether we find mold requiring sanitizing. We don’t quote over the phone without asking about your building type — a Somerville triple-decker retrofit is a different job than a 1990s split-level in West Somerville. Estimates are free. Call (877) 517-5646 and Thomas will walk through what you’re working with.

FAQs — HVAC Cleaning in Somerville
Retrofitted forced-air systems in Somerville’s triple-deckers use flex duct with tight bends, low airflow velocity, and minimal filtration — all of which accelerate debris accumulation compared to purpose-built systems. The original steam or hot-water buildings were never designed for air movement, so the retrofit ductwork acts more like a lint trap than a smooth airway. Call (877) 517-5646 for a free inspection — we’ll show you exactly where your system is trapping debris.
Yes — we’ve cleaned systems accessed through closets, bulkhead hatches, and even exterior crawlspace entries in Somerville’s dense housing. Our Nikro and Rotobrush equipment breaks down for tight carries, and Thomas has navigated access routes that larger crews simply won’t attempt. The job takes longer, but it’s absolutely doable. Call for an estimate based on your specific access.
Yes, we clean coils in high-efficiency condensing furnaces — common in Somerville condo conversions — and we apply antimicrobial treatment to prevent mold in the humid basement environments where these systems often live. High-efficiency units have tighter coil spacing that traps debris faster; they need more attentive cleaning, not less. Call (877) 517-5646 to schedule.
Fine gray particulate that doesn’t match ordinary household dust, musty or metallic odors when the system starts, and increased allergy symptoms since 2015–2022 are all indicators. We’ve found this contamination in East Somerville properties along Medford Street and Washington Street — the dust is distinctive under magnification. We can inspect with a borescope and show you what’s in your system. Estimates are free.
We clean and service systems with Honeywell, Aprilaire, and Nikro components, and we use Abatement Technologies HEPA filtration during every job.
