Beyond Surface Cleaning: Duct Work That Actually Improves Airflow

What Fails When Ducts Go Unaddressed

Most duct systems accumulate years of dust, construction debris, and insulation fibers that settle in low points and cling to interior surfaces. Homeowners notice reduced airflow from registers, uneven temperatures between rooms, and dust reappearing on furniture shortly after cleaning. What they don't see: gaps at trunk line joints leaking conditioned air into attics, disconnected flex runs dumping air into crawlspaces, and register boots separated from drywall openings. These hidden losses waste energy and strain HVAC equipment cycling longer to compensate.

In Chatsworth, where valley air carries fine particulates and seasonal winds stir dust, duct interiors coat faster than in coastal zones. Lunar Air Services Inc. uses rotating brush systems and negative air machines to dislodge accumulated material, then captures it before recirculation. The process removes allergens, mold spores, and debris that degrade indoor air quality and restrict airflow through return grilles.

Sealing That Restores System Efficiency

Duct sealing addresses leakage points discovered during cleaning inspection—separations at plenum connections, tears in flex duct, and unsealed register penetrations. Mastic sealant applied to joints creates airtight bonds that withstand temperature cycling and vibration, unlike foil tape that degrades within years. Aerosol sealant injected into pressurized ducts coats leaks from the inside, effective for concealed runs inaccessible without demolition.

Sealed ductwork delivers measurable improvements: static pressure drops across the system, airflow volume increases at registers, and temperature differentials between supply and return narrow. Furnaces and air conditioners reach setpoints faster, cycle less frequently, and consume less energy moving the same air volume. Indoor air quality improves as filtered air reaches living spaces instead of pulling unfiltered air through building cavities to replace leaked volume.

Evaluating Duct System Condition

Duct cleaning and sealing decisions depend on observable system behaviors and measurable performance losses. Effective service targets specific problems rather than applying blanket treatments.

• Visible dust accumulation around supply registers indicating dirty ductwork or inadequate filtration
• Uneven room temperatures despite properly functioning equipment pointing to airflow restrictions
• Excessive runtime to reach thermostat setpoints suggesting conditioned air losses
• Allergy symptoms worsening indoors as accumulated duct debris recirculates through Chatsworth homes
• Energy bills climbing without corresponding usage changes, signaling system inefficiency

Duct systems cleaned and sealed to eliminate leakage and contamination improve comfort, efficiency, and air quality. Contact us for an inspection to identify issues affecting your ventilation system.
