AIR DUCT CLEANING
AIR DUCT CLEANING
Air ducts need to be cleaned at least once every five years. If your air ducts have not been cleaned lately, call us to schedule a home air duct system cleaning today. We use a HEPA air vacuum that removes all particulates inside your home’s air duct system. Once the duct system has been cleaned, we recommend using an air scrubber that will clean your air as it passes through the system using a UV light that kills bacteria, mold spores, and airborne pollutants. You will definitely notice a difference in the air quality.
AIR DUCT SEALING
The #1 cause of air duct pollution is leaky air ducts. Air is pulled through the return air duct system and when the duct system is not 100% sealed, it pulls in dirty hot air from the attic around the registers, connections, filter box, and rips and tears in the duct. Not only does it allow dirty air into the ducts, but it also lets the cool air escape out, causing your unit to run longer and drive your electricity bill higher.
HAND DUCT SEALING
As long as you have access to your attic, hand duct sealing is the best way to seal your ducts. We get into the attic and hand seal all couplings, seams, metal duct connections, flex duct connections, plenum boxes and supply registers where they meet the drywall. This process usually takes at least two technicians at least four hours to seal all duct connections. This will cost about 50 cents per square foot of the home’s livable square footage. So a 1,600-square-foot home would be $800.
- Aeroseal Duct Sealing is a patented breakthrough technology that tackles leaks from the inside out. Aeroseal software allows the technician to accurately measure the duct leakage in residential homes and commercial buildings. The Aeroseal process puts escaping air under pressure and causes polymer particles to stick first to the edges of a leak, then to each other until the leak is closed.
- The technology was developed within the Indoor Environment Program at Lawrence Berkeley National Laboratory, whose IAQ scientists tested it. The research was funded by the U.S. Environmental Protection Agency, the U.S. Department of Energy, Electric Power Research Institute and California Institute of Energy and Environment.
- The University of California was granted initial patents in 1996 and 1999, and Aeroseal holds an exclusive license to the technology. AEROSEAL costs about $1,800 per duct system and comes with a 10-year warranty. We usually only suggest using Aeroseal when you have a flat roof and there is no access to an attic to get to ductwork.
Honeywell Air Scrubbers/UV lights
These UV lights are mounted inside the duct system near the evaporator coil, where mold and mildew grow from the humidity and condensation generated from the air conditioner. The bulbs will last about two years and need to be replaced to help keep them effective.
