The ductwork running through your walls and ceilings is the hidden backbone of your HVAC system — and when it's dirty or leaking, your entire home suffers. HVAC Proz provides professional duct cleaning using truck-mounted and portable vacuum systems combined with agitation tools that dislodge debris, dust, allergens, mold spores, and construction contamination from supply and return ducts throughout your Los Angeles property.
Beyond cleaning, leaky ducts are one of the leading causes of high energy bills and uneven temperatures in LA homes. Studies consistently show that the average forced-air system loses 20–30% of conditioned air through duct leaks in unconditioned attic and crawl spaces. HVAC Proz technicians locate leaks using pressure testing and seal them with code-compliant UL 181-rated mastic compound or professional aerosol sealing, significantly improving your system's delivered capacity and efficiency.
After service, we provide a before-and-after report documenting duct conditions, debris levels, and any leakage measurements taken. Cleaner, tighter ducts mean better indoor air quality, lower utility bills, and a longer-lived HVAC system.
