Our HVAC Cleaning Services in Hudson

Evaporator Coil Cleaning

The evaporator coil in your Hudson home’s air handler does the heavy lifting all summer, and in this town it works overtime. Hudson’s location in the Assabet River valley traps humidity against the hills, so coils stay wet longer and collect microbial growth faster than systems in drier neighboring towns. We remove the coil assembly when accessible, clean it with foaming cleaner, and apply an antimicrobial treatment that keeps mold from regrowing through the season. In older Hudson homes with retrofit air handlers crammed into former closets or basement corners, coil access is tight - our techs have the compact tools and the patience to do it without damaging surrounding ductwork.

Blower Cleaning

A dirty blower wheel cuts airflow by 30% or more and strains your motor until it fails. In Hudson’s older mill-era housing, blowers are often tucked behind sharp 90-degree bends in undersized sheet-metal trunks that were never designed for modern equipment. We use flexible-drive Rotobrush systems with high-torque heads that can navigate those tight turns without dislodging the fragile flex-duct connections that are common in retrofitted systems. On a recent HVAC Cleaning job in a triple-decker on a lower street near the Assabet River floodplain, our techs found a return-air plenum lined with mold and decades of lint, trapped behind a maze of sharp 90-degree bends. Using a Rotobrush system with a high-torque head, we navigated the tight turn and reached the blower, which had a clogged evaporator coil that we treated with an antimicrobial coil treatment. The homeowner now has cleaner airflow and we eliminated the musty odor that had been persisting for years.

Condenser Cleaning

Your outdoor condenser coil in Hudson faces a specific challenge: cottonwood fluff from the Assabet River corridor, plus the fine grit that blows off construction and roadwork along Route 111 and Lowell Road. We pull the fan assembly when the design allows, straighten bent fins, and deep-clean the coil with foaming cleaner and low-pressure rinse. A clean condenser runs cooler, draws less power, and lasts longer - critical when Hudson’s summer humidity has your system running 16 hours a day.

Air Handler Cleaning

The air handler is the heart of your forced-air system, and in Hudson’s older homes it’s often a cobbled-together unit sitting on a basement slab or hung from a closet ceiling with minimal clearance. We clean the cabinet, the drain pan, the blower compartment, and all accessible duct connections. Where we find standing water or mold in the drain pan - common in river-adjacent Hudson neighborhoods with high groundwater - we treat with antimicrobial and check the condensate drain line for clogs that could flood your basement.

Coil Treatment

After cleaning, we apply a professional-grade antimicrobial coil treatment that inhibits mold and bacterial regrowth for the cooling season. In Hudson’s humid river-valley climate, this step isn’t optional - it’s what keeps your system from smelling musty two weeks after cleaning. We use treatments compatible with Aprilaire and other major brands, applied at the correct concentration for residential systems.

Heat Exchanger Cleaning

For homes with fossil-fuel furnaces, the heat exchanger is where combustion happens and where cracks can leak carbon monoxide. We inspect and clean accessible heat exchanger surfaces during our HVAC cleaning service, and if we find damage or heavy soot, we flag it for repair before it becomes a safety issue. In Hudson’s older housing stock with original or replacement furnaces dating to the 1980s and 90s, this inspection has caught problems that could have turned dangerous.

Trusted Brands We Service in Hudson

We clean and maintain equipment from every major manufacturer, and we stock common parts for fast turnaround on Hudson jobs. Our service vans carry Rotobrush cleaning systems, Abatement Technologies HEPA vacuums, and Aprilaire media filters and humidifier components. For antimicrobial treatments and coil cleaners, we use products from Guardsman that are specified by serious HVAC contractors, not the consumer-grade bottles you’ll find at the hardware store. When your Hudson home’s system needs a part we don’t have on the van, our Boston office sources it quickly - we don’t leave you waiting a week for a filter bracket or a blower belt.

Common HVAC Cleaning Problems We See in Hudson Homes

• Failed duct-tape seals in retrofit trunk lines. Hudson’s 19th-century mill housing got forced-air systems decades after construction, and the original installers used cloth duct tape that has dried out and failed. We find gaps blowing conditioned air into basement cavities and wall chases, which we seal with proper mastic during cleaning.
• Mold in return-air plenums near the Assabet River. The floodplain neighborhoods on Hudson’s lower streets have enough ground-level humidity that mold colonizes return plenums and blower compartments regularly. We treat with antimicrobial and recommend dehumidification strategies, but the root cause is Hudson’s specific geography - something you don’t see in drier neighboring towns.
• Dislodged flex-duct connections from careless cleaning. In Hudson’s older retrofit systems, over-aggressive brushing can dislodge fragile flex-duct connections, turning a cleaning into a repair job. Our techs know to inspect every connection before applying brush pressure, and we use lower-torque settings on tight bends.
• Damage to tight access points from hose handling. Failing to protect tight, alley-load access points when running hoses can damage trim or doors in Hudson’s dense townhome-style buildings - a common and avoidable mistake. We lay runners, pad corners, and assign a second tech to manage hose routing when access is constrained.
