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.

AfterTrane Air Duct Cleaning in Boston, CA | Hollis Air Duct Cleaning
Trane air duct cleaning in Boston is a different job from what you’d get in a newer city. The answer most homeowners need: we clean, seal, and balance Trane ducted systems throughout Boston at a flat, written price before any work starts, and we’re independent, so no factory warranty games. The one thing that makes our Trane work different here is knowing how these systems behave inside 19th-century triple-deckers and pre-war rowhouses, where the ductwork was never designed for a modern Trane air handler. Call (361) 326-5060 for a free estimate on your Boston system.
Why Boston Residents Choose Us for Trane Service
We’ve been doing Trane sales & service work long enough to know the equipment line by heart. XR Series heat pumps, XB air handlers, XV variable-speed systems, ComfortLink II controls. More than that, we know how those units actually run inside Boston’s housing stock. Triple-deckers squeeze Trane air handlers into closets never built for airflow. Rowhouse basements swallow equipment runs that sweat through every humid July. Roy Castellanos, our owner, came up through the sheet metal and air conditioning program at Los Angeles Trade-Technical College and spent years doing hands-on duct work before starting Hollis. He trains the crew to check static pressure, not just vacuum registers. That’s the difference when you’re in a building where one return trunk serves three floors of tenants.
We show up uniformed, background-checked, and inside the quoted window. The price is written down before we touch anything. And every job carries the 365-Day Done Right Promise. If the work fails within a year, we come back and make it right at no charge. No fine print, no moving targets. That’s The Garrison Standard, and it’s what we hold ourselves to on every Boston service area call.
Common Trane Air Duct Cleaning Problems We Solve in Boston
- Coil biofilm in humid basements and attics. Trane’s all-aluminum evaporator coils have tight fin spacing. In Boston’s coastal humidity, that spacing traps moisture and dust together, forming the sticky microbial film that chokes airflow. We see it constantly in uninsulated rowhouse basements where the coil never fully dries between cycles.
- Variable-speed blowers overcompensating for leaky flex duct. Trane variable-speed air handlers with constant-torque or communicating motors will ramp up when they detect high static pressure. In older Boston homes, flex duct snaked through unheated attics collapses or tears at the connector collars. The unit works harder, you hear it struggling, and still don’t get even airflow room to room.
- Rusted metal supply trunks in pre-war basements. Trane supply trunks routed through cold, uninsulated basement or attic chases sweat during Boston’s humid summers. Then they rust and flake internally, and you start seeing iron-oxide dust on registers. In shared-return buildings, that dust moves through multiple units.
- Cabinet and plenum seams that fail after freeze-thaw cycles. Historic-district Boston installs often have ducts sealed with lightweight mastic or old duct tape. Freeze-thaw cycling breaks those seams every few winters. Return-side dust pulls in from basements and chases, coating the blower and secondary heat exchanger with fine particulate.
- Shared returns pulling neighbor’s air through one Trane handler. The big one in Boston triple-deckers. A single return trunk between units means one floor’s cooking odors, pet dander, or smoke ends up in another unit’s Trane evaporator coil. Cleaning alone won’t fix it. The return needs isolation or reconfiguration.
Trane Service in Boston: What Local Conditions Mean for Your Equipment
Here’s the fact that shapes more of our Boston work than anything else: in a triple-decker, one shared return trunk often serves multiple units, and a Trane air handler on one level pulls air from the apartments below. The Trane variable-speed blower with its higher static pressure makes this worse, not better. It actively draws from wherever the return path leaks, and in a 1920s wood-frame building, that’s the neighbor’s kitchen. We see Trane XR coils coated in a film that’s part cooking grease, part cigarette tar, part ordinary Boston dust. The fix is never just Air Duct Cleaning - Boston vacuuming the return. Sometimes we cut the shared trunk and seal it with rigid metal and mastic. Sometimes we add a filter grille sized for the top-floor unit. In one triple-decker on Dorchester Avenue, we dropped a Trane variable-speed blower from a laboring 80% ramp to a quiet low stage by reworking the return alone. No new equipment. Just the ductwork doing what it was supposed to do.
Boston’s cold winters and muggy summers mean systems run hard in both seasons. Freeze-thaw cycles crack sealant. Coastal humidity feeds microbial growth. None of this shows up in a generic Trane service bulletin. It shows up in the buildings themselves, and you have to be here, opening up chases and pulling coils, to know what you’re looking at.
Trane Models & Products We Service in Boston
We work on the full residential Trane line in Boston: XR Series heat pumps and air conditioners, XB Series air handlers and furnaces, XV Series variable-speed communicating systems, and S-Series units tied to ComfortLink II controls. For critical components, control boards, motors, coil assemblies, we use Trane OEM parts when the system is under warranty or the communicating controls need a factory match. For duct-side work, flex, mastic, sealing components, we use high-quality aftermarket materials where OEM equivalents either don’t exist or add nothing. If a Trane coil or heat exchanger is corroded beyond cleaning, we tell you straight and quote repair versus replacement. We won’t push a new system on you for what’s actually a Boston Dryer Vent Cleaning duct problem.
Our focus on this page: return duct cleaning, duct sealing, and evaporator coil cleaning. Those three services fix the majority of Trane airflow complaints in Boston housing stock.
Trane Service Pricing in Boston
Air duct cleaning on a Trane system in Boston typically runs $450 to $900 for a full single-family home or one floor of a triple-decker, depending on system size, number of returns, and how much of the ductwork is accessible. Adding evaporator coil cleaning runs $150 to $350. Duct sealing with mastic and rigid metal at problem joints runs $75 to $150 per access point we open. Every quote is written before work starts, and it doesn’t move at the door. What drives the price here specifically: older Boston buildings often have returns buried behind plaster or in narrow chases, which takes more time to access properly. A free estimate means we look at your actual system and duct layout, then hand you a number in writing. Call (361) 326-5060 to schedule one.

FAQs – Trane Air Duct Cleaning in Boston
Duct cleaning alone won’t fix it. The smell is coming through a shared return trunk that pulls air from the neighboring unit into your Trane air handler. What fixes it is isolating that return, sealing the trunk with mastic and rigid metal, and possibly adding a properly sized filter grille at your unit. That’s return duct reconfiguration, not just cleaning. Call (361) 326-5060 and we’ll trace the return path and tell you exactly what’s needed.
Because your evaporator coil is likely coated in the sticky film that forms when humid Boston air meets the tight fin spacing on Trane’s all-aluminum coils. Add the dust load from running the system hard through both heating and cooling seasons, and airflow drops. Cleaning the coil restores it. We do this as part of our Trane-focused service in Boston.
Interior duct cleaning work generally does not, because it happens inside your home and doesn’t alter exterior appearance or structure. What matters is whether the work touches structural framing or requires new exterior penetrations. We’ll flag any local Boston historic-district considerations before we start, and we’ll work through what’s needed with you.
Yes. Cleaning the ductwork doesn’t require changing system programming. We don’t reset or reflash anything on a ComfortLink II system unless we’re asked to and the specific job calls for it. The blower runs during cleaning, but the settings stay exactly as they were.
Every 3 to 5 years is a reasonable interval, but a shared return or heavy pet load can shorten that. If you’re noticing dust on registers within weeks of cleaning, or smells migrating between units, call us for an assessment. The return layout determines more than the calendar does.
