Why You Need Air Duct Sealing in San Rafael


Signs You May Need Air Duct Sealing in San Rafael:


Are your utility bills unusually high during extreme weather? Does your home take a long time to heat or cool? Is there noticeable dust and debris being blown through your living space? These issues might indicate holes, leaks, disconnected ducts, or unbalanced air distribution.


Sealing your air ducts can improve comfort and energy efficiency in your home. According to Energy Star, 20-30% of air moving through your ducts can be lost due to these problems, causing your HVAC system to work harder and potentially drawing dust from the attic or crawl space into your home.

The Air Doctor Standards


 Air Doctor adheres to NADCA standard specification guide and uses the source removal method. We use a portable HEPA filtered air duct vacuum system (and/or gas-powered commercial air duct vacuums) to clean all supply ducts, return air ducts, and plenums. This system is brought into each room and used in conjunction with a compressed air whip (and/or rotating power brushes). The air whip agitates the duct while the HEPA filtered air duct vacuum system creates a negative vacuum at 3500 cfm (up to 10,000 cfm with our gas-powered commercial air duct vacuums). Once each supply air duct is cleaned, the return air system is cleaned in the same fashion. Finally, we clean the furnace unit.
