Duct Work

Energy efficient HVAC systems depend on quality duct work. Without properly sealed and balanced ducts, a new shiny piece of heating or cooling equipment cannot provide real comfort and efficiency. Duct leakage is not only an efficiency issue, but also a significant issue for indoor air quality and home comfort. To achieve your goals in home performance we ensure you have properly sealed by conducting duct testing before and after our duct work. This includes thoroughly cleaning air ducts to confirm maximum performance.  A few interesting facts:

Efficiency:
• “You can lose up to 60% of your heated air before it reaches the register if your ducts aren’t insulated and they travel through unheated spaces such as the attic or crawlspace.” -U.S Dept. of Energy

• Duct systems in older homes in the Bay Area leak an average of 30-40%. That’s like throwing away $0.40 for every dollar you spend on heating!

Air Quality:
•Leaky HVAC air ducts are often located in the attic or crawlspace. This can cause major indoor air quality issues.

•Damp crawlspace can cause mold growth and high humidity. When the furnace goes on, the leaky duct system can draw this unhealthy air and distribute it throughout the house.

Comfort:
•Fixing the leaks can provide more air flow to the rooms where you want it. A common complaint is that some rooms are too hot/cold or don’t receive enough air flow.

•To help balance the system and deliver correct air flow to individual rooms, we can adjust the in-line dampers on the furnace to redirect the heat where you want it. If you have an older duct system, you may need to have dampers installed in order to do this.
