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.

AfterCarrier Air Duct Cleaning in Baltimore, CA | Hollis Air Duct Cleaning
Carrier air duct cleaning in Baltimore typically runs $350 – $650 for a full rowhouse system, depending on duct length and how much sealing the job requires. We’re Hollis Air Duct Cleaning, an independent Carrier service provider, and the reason our work here is different comes down to one thing: Baltimore’s rowhouses don’t just need debris removed, they need ducts sealed against shared-wall cross-contamination. Roy Castellanos and our crew have spent years working Carrier systems in these 19th-century homes. Call (361) 326-5060 for a written estimate before any work begins.
Why Baltimore Residents Choose Us for Carrier Service
Carrier builds equipment that shows up in a lot of Baltimore homes: Infinity systems in renovated rowhouses, Performance and Comfort units in retrofits, ductless 38MURA setups in additions. We know how each line behaves when it’s hooked to original galvanized ductwork in a 100-year-old house. Our Carrier sales & service experience comes from actual job sites, not manuals. Roy Castellanos learned the mechanical trade at Los Angeles Trade-Technical College and has spent his career in duct work, so when he tells a Baltimore homeowner their Carrier blower is clogged with coal dust, he’s talking from what he’s seen with his own hands. We’re background-checked, uniformed, and we show up inside the window we quoted. Every job gets a written price before we touch anything, and it doesn’t move at the door.
Common Carrier Air Duct Cleaning Problems We Solve in Baltimore
- Mold on Carrier evaporator coils in humid summers. Baltimore’s muggy season makes coils sweat, and that moisture breeds biofilm on Infinity coil surfaces. The result is a musty smell every time the AC cycles. We clean the coil and treat the drain pan so the odor doesn’t return in six weeks.
- Coal dust sucked through floor register gaps. In neighborhoods like Hampden and Federal Hill, original floor registers sit over old coal basements. When the Carrier blower pulls return air, those gaps act like vacuum ports. We seal them with mastic and clean the blower wheel, which is usually coated black.
- Variable-speed blower dust buildup causing shutdowns. Greenspeed ECM motors run hot and collect fine dust. Baltimore’s freeze-thaw winters create condensation in crawlspace ducts, and that moisture makes dust cling harder. The blower overheats and shuts down intermittently. Cleaning the wheel and housing restores operation.
- Shared-wall duct leaks between attached rowhouses. This is the Baltimore problem. Two units share a wall, and often share duct chases. When one neighbor’s Carrier system runs, it can pull air from the other side. Pressure imbalances and uneven room temperatures follow. Duct sealing isn’t optional here; it’s the core of the job.
- Clogged filters from plaster dust and pest debris. Plaster walls shed fine dust for decades, and older Baltimore homes have duct runs through unheated crawlspaces where pests get in. That combination loads up Carrier filters fast. We show homeowners before-and-after photos so they can verify the work.
Carrier Service in Baltimore: What Local Conditions Mean for Your Equipment
Here’s a fact that holds true in Baltimore and almost nowhere else: this city has the densest concentration of 19th-century rowhouses with original galvanized ductwork in the United States. That matters for your Carrier system in a way it wouldn’t in Fresno or Sacramento. Galvanized steel ducts from that era were joined with slip connections, not sealed seams. Over a century, those joints open up. When a Carrier Infinity blower pushes air through those leaky runs, the system can’t hold static pressure, so rooms get uneven temperatures and the blower works harder than Carrier designed it to. Worse, return-side leaks in shared walls pull air from the attached unit next door. Standard duct cleaning ignores this; it only vacuums what’s already inside. Our approach serving Baltimore, MD always includes sealing accessible seams with mastic, because cleaning a leaky system is just moving air around. If you live in a rowhouse, ask any contractor one question: are you sealing the ducts or just cleaning them? The answer tells you everything.
Carrier Models & Products We Service in Baltimore
We work on Carrier Infinity systems with Greenspeed variable-speed technology, Performance 14 – 17 SEER2 units, Comfort series base models common in rowhouse retrofits, and 38MURA/40MUAA ductless systems installed in Baltimore additions. For parts, we use OEM Carrier components when fit and longevity matter: blower motors, control boards, coil assemblies. For wear items like filters and gaskets, quality aftermarket equivalents do the job and keep your cost down. We keep common Carrier filter sizes and mastic on our trucks, so a standard Baltimore rowhouse job doesn’t stall waiting on a parts run. If your Carrier unit is past 15 years and facing a major repair, we’ll give you an honest repair-versus-replace assessment rather than push a sale.
Carrier Service Pricing in Baltimore
Air duct cleaning for a typical Baltimore rowhouse runs $350 – $650 for the full system. What moves the number: how many returns the house has, whether ducts run through accessible crawlspace or finished ceilings, and how much sealing the job needs. Houses with heavy coal-dust contamination or shared-wall leaks sit at the higher end because the work includes mastic sealing at floor registers and duct seams. A free estimate from us means we actually look at the system before quoting, and the price we write down is the price you pay. Call (361) 326-5060 to schedule an inspection.

FAQs – Carrier Air Duct Cleaning in Baltimore
The smell comes from mold and biofilm growing on your Carrier evaporator coil. Baltimore’s humid summers make coils stay wet for weeks, and that moisture feeds microbial growth. Cleaning the coil and treating the drain pan removes the odor source. We recommend coil cleaning alongside duct cleaning if your system smells. Call (361) 326-5060 and we’ll inspect it.
Yes. We use negative-air extraction with soft rotary brushes, not aggressive tools that score metal. Baltimore Air Duct Cleaning requires care: original galvanized ducts from the early 1900s are more brittle than modern sheet metal, so we inspect access points before starting and clean at lower brush speeds. The cleaning itself won’t harm sound ductwork; the bigger risk is ignoring leaks at the seams, which we seal with mastic after cleaning.
It can, if the imbalance comes from blocked or leaky ducts rather than the system itself. In Baltimore rowhouses, we frequently find return-side leaks in shared walls that pull air from the neighboring unit and drop static pressure to the far rooms. Cleaning removes the obstruction, sealing fixes the leak. If the imbalance persists after both, the issue may be zoning or damper settings, which we’ll report honestly.
Every 3 – 5 years for most Baltimore homes, and closer to every 2 – 3 years if you live in a rowhouse with original plaster walls, a coal-dust basement, or pets. Coal dust and plaster fines accumulate faster than typical household dust. If you’re seeing dust on registers within days of cleaning surfaces, it’s time. Call (361) 326-5060 and we’ll give you a straight answer on whether it’s due.
We do. Carrier 38MURA and 40MUAA ductless systems show up often in Baltimore rowhouse additions and finished attics. The indoor units have blower wheels and filters that need cleaning just like ducted systems. We clean the blower wheel, wash the filter, and check the drain line. Ductless units in humid Baltimore summers are prone to the same coil mold issue, so we include Dryer Vent Cleaning in Baltimore and coil cleaning on those calls.
