KIC Refrigeration starts every duct cleaning in Portsmouth, NH with a thorough inspection. We document the current condition of your supply ducts, return ducts, and trunk lines with photos, check for biological growth or contamination, and design a cleaning plan specific to your duct material and layout.
At your Portsmouth property, our crew connects a negative air machine to your main trunk line, creating powerful suction throughout the system. We then insert rotary brushes and compressed air tools into each supply and return run to dislodge accumulated dust and debris, which is pulled directly into our HEPA-filtered collection unit.
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.
KIC Refrigeration verifies every duct cleaning in Portsmouth, NH with a final inspection and airflow test. We provide before-and-after photo documentation, install a clean filter, measure supply register CFM, and confirm your system is delivering cleaner air at improved volume throughout your home.
Everything you need to know before scheduling air duct cleaning for your property.
Professional air duct cleaning in Portsmouth 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 Portsmouth.
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 Portsmouth home for maximum efficiency improvement.
Yes. KIC Refrigeration offers dryer vent cleaning as an add-on service during air duct cleaning appointments in Portsmouth. Lint-clogged dryer vents are a serious safety hazard — the U.S. Fire Administration reports that clothes dryers cause approximately 2,900 residential fires per year, and lint buildup in the exhaust vent is the leading contributing factor. A clogged vent restricts exhaust airflow, causes the dryer to overheat, increases drying time by 2 to 3 times normal, and dramatically raises fire risk. Our technicians clean the entire vent run from the dryer connection through the exterior wall or roof termination, verify proper airflow with an anemometer, and inspect the vent cap for damage or blockage.
The National Air Duct Cleaners Association recommends professional duct cleaning every 3 to 5 years for most homes. However, several factors can shorten that interval for Portsmouth properties. Homes with indoor pets that shed hair and dander, smokers, family members with asthma or severe allergies, recent remodeling or construction, or visible mold growth in or around duct registers should be cleaned more frequently — every 2 to 3 years. New construction homes should be cleaned before occupancy to remove accumulated drywall dust, sawdust, paint overspray, and construction debris that settles inside the ductwork during the building process. KIC Refrigeration inspects your Portsmouth ducts and recommends a cleaning schedule based on actual conditions.
