A clear, step-by-step approach to every air duct cleaning project we take on.
Our Marlborough technician inspects your supply and return ducts at multiple access points and registers. We photograph conditions inside the ductwork, check for mold growth, measure dust accumulation, and inspect duct connections for damage or disconnection before cleaning begins.
KIC Refrigeration uses the source removal method recommended by NADCA for duct cleaning in Marlborough, CT. Our negative air machine generates 10,000+ CFM of suction at the trunk while our technician agitates each branch with rotating brushes sized to the duct diameter. All debris is captured in a HEPA-filtered unit — nothing recirculates into your home.
We clean the blower housing, evaporator coil surface, return plenum, and supply plenum — the components where dust accumulates most and restricts airflow. A clean coil and blower improve both air quality and system efficiency.
Our Marlborough crew performs a post-cleaning camera inspection to document the results. We compare before and after conditions at each access point, install a new filter, and verify that airflow at supply registers has improved — confirming the cleaning made a measurable difference.
Common questions about air duct cleaning costs, timelines, and what to expect.
Professional air duct cleaning in Marlborough typically costs $300 to $600 for a standard home with a single HVAC system and 8 to 15 supply registers. Homes with multiple HVAC systems, extensive ductwork runs, or severe contamination from mold, rodents, or post-construction debris may run $600 to $1,200. Be cautious of companies advertising $99 or $149 whole-house duct cleaning specials — legitimate source removal cleaning requires a negative air machine, mechanical agitation tools, and 3 to 5 hours of skilled labor. Lowball pricing usually means a quick run-through with a shop vacuum that leaves most of the contamination in place. KIC Refrigeration provides honest, transparent pricing for genuine duct cleaning in Marlborough.
Yes. KIC Refrigeration follows NADCA ACR Standard 2021 — the Assessment, Cleaning, and Restoration standard published by the National Air Duct Cleaners Association — for all duct cleaning work in Marlborough, CT. We use the source removal method, which is the only cleaning approach that NADCA and the EPA recognize as effective. This involves connecting a negative air machine to the trunk line to create sustained negative pressure throughout the duct system, then mechanically agitating each branch with rotating brushes and compressed air whips to dislodge contaminants, which are pulled into a sealed HEPA-filtered collection unit. We do not rely on chemical fogging, ozone generators, or sealant sprays as substitutes for proper mechanical cleaning.
Yes. Dust and debris buildup on the blower wheel, evaporator coil surface, and inside duct runs creates measurable airflow restriction. When airflow drops below the designed 400 CFM per ton, the system works harder and runs longer cycles to reach thermostat setpoint, consuming more energy and putting extra stress on the compressor. A heavily contaminated evaporator coil can reduce cooling capacity by 10 to 20 percent. Cleaning restores designed airflow through the system, reducing energy consumption by an estimated 5 to 15 percent depending on contamination severity. KIC Refrigeration cleans the blower wheel, blower housing, and evaporator coil surface in addition to all duct runs during every duct cleaning project at your Marlborough home for maximum efficiency improvement.
Many Marlborough customers with dust allergies, pet allergies, or general respiratory sensitivity report noticeable improvement in symptoms after professional duct cleaning. Over several years, ductwork accumulates layers of dust, pollen, pet dander, mold spores, dust mite debris, and other allergens that recirculate through your home every time the blower runs. The EPA estimates that indoor air can be 2 to 5 times more polluted than outdoor air, and contaminated ducts are a significant contributor. Professional source removal cleaning extracts this accumulated material from the duct walls and register boots. Combined with a high-quality MERV 11 or MERV 13 filter changed every 60 to 90 days, clean ducts measurably reduce airborne allergen concentration in your Marlborough home.
