Our HVAC Cleaning Services in Hollis

Evaporator Coil Cleaning

The evaporator coil in your Hollis home’s air handler sits in a dark, humid environment six months of the year while your heating system runs. Southern New Hampshire’s long heating season, from October through April, means that coil accumulates dust, pollen, and microbial growth faster than in milder climates. We access the coil, apply foaming cleaner, and rinse thoroughly so it transfers heat efficiently again. A clean coil can drop your energy bills and eliminate the musty smell that blows from vents in homes near the dense tree cover of Hollis‘s rural lots.

Blower Cleaning

The blower motor and wheel push every cubic foot of air through your Hollis home’s ductwork. When the wheel fins clog with debris, airflow drops, the motor strains, and you hear that low rumble from the basement. We remove the blower assembly, clean the wheel and housing, and re-balance the system. In Hollis’s older raised-ranch homes, where the air handler often sits in a damp basement corner, blower cleaning is one of the most impactful single services we perform.

Condenser Cleaning

Your outdoor condenser unit draws air through its coils, and Hollis’s heavily wooded properties deliver exceptional pollen loads in spring and leaf particulates in fall directly to that intake. We wash the coils, straighten damaged fins, and clear the cabinet base so the unit can reject heat properly. This matters especially before the cooling season, when a dirty condenser will run longer, cost more, and fail sooner.

Air Handler Cleaning

The air handler is the central station of your forced-air system, and in Hollis homes with basement-mounted units, it’s often the dirtiest component we find. We clean the cabinet, drain pan, and associated components, then run our camera through the attached plenum to verify nothing was missed. For homes with whole-house humidifiers, and that’s most of Hollis, this is where we also inspect for the mineral scale and microbial growth that well-water systems produce.

Heat Exchanger Cleaning

The heat exchanger is the barrier between combustion gases and your breathing air, and any breach is a serious safety concern. We inspect and clean exchanger surfaces during our HVAC cleaning service, looking for corrosion, cracks, or soot buildup that could indicate incomplete combustion. In Hollis’s 1990s-era homes with original furnaces, this inspection has caught deteriorating exchangers before they became hazardous. We do not perform DIY-level checks; this requires trained technicians with proper detection equipment.

Coil Treatment

After mechanical cleaning, we apply EPA-registered coil treatment products to inhibit microbial regrowth on evaporator and condenser coils as part of our Air Quality & Sanitizing - Hollis service. In Hollis’s well-water homes, where humidifier pans and coils already face elevated bioburden from mineral-rich moisture, this treatment extends the cleanliness of the service. We use Abatement Technologies products applied according to manufacturer specifications, not over-the-counter sprays.

Trusted Brands We Service in Hollis

We carry professional-grade equipment and replacement parts from Rotobrush, Abatement Technologies, and Aprilaire on every truck, and we stock common humidifier pads and filters for Hollis customers so most jobs finish in one visit. Aprilaire whole-house humidifiers are especially common in this market, and we keep the 35-, 45-, and 600-series pads in stock because we know what Hollis well water does to them. When a component needs ordering, our supply chain reaches Nashua and beyond with next-day turnaround, but same-day completion is our standard.

Common HVAC Cleaning Problems We See in Hollis Homes

• Mineral scale and microbial growth in humidifier-attached plenums. Nearly every Hollis home draws from a private well, and southern New Hampshire groundwater carries elevated minerals and iron. Whole-house bypass humidifiers deposit that scale inside supply plenums and trunk lines, creating a contamination pattern far more prevalent here than in municipal-water-served towns like Nashua. Every duct-cleaning job in Hollis should include a humidifier pan and duct inspection for this reason.
• Rodent contamination in basement return chases. As temperatures drop each October, field mice move indoors across Hollis’s rural lots and frequently enter duct systems through basement return grilles or gaps around floor registers, leaving nesting material, dander, and droppings in main trunk lines. Local technicians know to probe lower-level return chases before quoting a standard clean, because rodent contamination here often requires EPA-registered sanitizer application on top of mechanical cleaning.
• Condensation moisture in unconditioned basement duct runs. Hollis’s housing stock of custom-built colonials and raised-ranches typically routes flex and sheet-metal duct through unconditioned basements. That basement routing exposes duct runs to condensation moisture and rodent pressure, common findings on service calls throughout town, and leads to recurrent debris accumulation if not properly addressed.
• Accelerated debris loading from wooded lot particulates. Hollis’s densely wooded, large-lot character delivers exceptionally high spring pollen loads and heavy fall leaf particulates directly to outdoor return-air intakes, speeding interior duct fouling compared to more open suburban layouts. Systems here often need more frequent attention than identical equipment in cleared developments.
